How Basement Supports Impact Floors Above:  Adjustable Steel Columns

11/7/2018

0 Comments

 
If you have a basement, or a crawl space, you probably have adjustable steel columns, also known as screw jacks and beam jacks.  These are hollow steel posts designed to provide structural support. An attached threaded adjustment mechanism is used to adjust the height of the post.  Adjustments can properly distribute support to the floors above, to prevent out of level conditions that might cause structural damage.  A professional home inspector can determine if these appear to be properly positioned and adjusted, or may suggest consulting a Structural Engineer.
​A few facts about adjustable steel columns:
  • They are usually found in the basement.  In some places, these are called lally columns, but this term can also apply to columns that are concrete-filled and non-adjustable.
  • Adjustable steel columns can be multi-part assemblies, sometimes called telescopic steel columns, or they can also be single-piece columns.
Defects that are often found in adjustable steel columns:
  • The 2012 International Residential Code (IRC), Section R407.3, columns (including adjustable steel columns) says... Adjustable steel columns "shall not be less than 3-inch diameter standard pipe." 
It is possible that a 2½-inch post may be able to support the load above it. However, supports smaller than 3 inches in diameter would violate the IRC even if not necessarily defective. In some cases, a 4-inch diameter post could buckle if the load exceeds the structural capacity of the post - even if not defective.  Structural engineers -- not inspectors -- are the authority on whether adjustable steel posts are of adequate size. But a professional home inspector can render an opinion as to when to consult a  Structural Engineer.
Picture
Other Possible Defects In Structural Supports:
  • Non Compliant Paint Allowing Rust To Form:  According to the IRC Section R407.2, All adjustable steel columns should be protected by rust-inhibitive paint.  It says, specifically, "All surfaces (inside and outside) of steel columns shall be given a shop coat of rust-inhibitive paint, except for corrosion-resistant steel and steel treated with coatings to provide corrosion resistance."   Inspectors will not be able to identify paint as rust-inhibitive, but may be able to observe the earliest stage of rust beginning to form and recommend further attention.  In dry climates where rust is not as much of a problem, rust-inhibitive paint may not be necessary. Visible signs of rust constitute a potential defect. Advanced rust will weaken the post and could cause structural collapse and extensive damage.
  • The post is not straight. The post should not bend anywhere along it's length or especially at its mid-point. Bent Posts indicate that the column cannot bear the weight of the house.  The maximum load is affected by many factors, such as the height and diameter of the post. 
  • The column is not connected to the floor. An inspector can determine whether a connection between the post and the floor exists as long as this connection has not been visually obscured.
  • The column is not connected to the beam. To provide proper support, the post should connect to the beam above.  This connection provides additional resistance against lateral displacement.
  • Too much extension:  If more than 3 inches of the screw thread are exposed the post may be overextended and thus have it's load bearing capacity reduced.
  • There are cracks in upstairs walls. If a post is not properly adjusted, then cracks may appear in walls.  This would suggest a failure of the columns.

Attic Pull-Down Ladders

4/24/2018

0 Comments

 
Attic pull-down ladders, also called attic pull-down stairways, are collapsible ladders that are permanently attached to the attic floor. Occupants can use these ladders to access their attics without being required to carry a portable ladder.
Common Defects
​
 Homeowners, not professional carpenters, usually install attic pull-down ladders. Evidence of this distinction can be observed in consistently shoddy and dangerous work that rarely meets safety standards. Some of the more common defective conditions observed by inspectors include:
  • cut bottom cord of structural truss. Often, homeowners will cut through a structural member in the field while installing a pull-down ladder, unknowingly weakening the structure. Structural members should not be modified in the field without an engineer’s approval;
  • fastened with improper nails or screws. Homeowners often use drywall or deck screws rather than the standard 16d penny nails or ¼” x 3” lag screws. Nails and screws that are intended for other purposes may have reduced shear strength and they may not support pull-down ladders;​
  • fastened with an insufficient number of nails or screws. Manufacturers provide a certain number of nails with instructions that they all be used, and they probably do this for a good reason. Inspectors should be wary of “place nail here” notices that are nowhere near any nails;
  • lack of insulation. Hatches in many houses (especially older ones) are not likely to be weather-stripped and/or insulated. An uninsulated attic hatch allows air from the attic to flow freely into the home, which may cause the heating or cooling system to run overtime. An attic hatch cover box can be installed to increase energy savings;
Picture
  • loose mounting bolts. This condition is more often caused by age rather than installation, although improper installation will hasten the loosening process;
  • attic pull-down ladders are cut too short. Stairs should reach the floor; 
  • attic pull-down ladders are cut too long. This causes pressure at the folding hinge, which can cause breakage;
  • improper or missing fasteners;
  • compromised fire barrier when installed in the garage;
  • attic ladder frame is not properly secured to the ceiling opening;
  • closed ladder is covered with debris, such as blown insulation or roofing material shed during roof work. Inspectors can place a sheet on the floor beneath the ladder to catch whatever debris may fall onto the floor; and
  • cracked steps. This defect is a problem with wooden ladders. 
  • In sliding pull-down ladders, there is a potential for the ladder to slide down quickly without notice. Always pull the ladder down slowly and cautiously. 

 Relevant Codes
The 2009 edition of the International Building Code (IBC) and the 2006 edition of the International Residential Code (IRC) offer guidelines regarding attic access, although not specifically pull-down ladders. Still, the information might be of some interest to inspectors.

2009 IBC (Commercial Construction):
1209.2 Attic Spaces. An opening not less than 20 inches by 30 inches (559 mm by 762 mm) shall be provided to any attic area having a clear height of over 30 inches (762 mm). A 30-inch (762 mm) minimum clear headroom in the attic space shall be provided at or above the access opening.

2006 IRC (Residential Construction):
R807.1 Attic Access. Buildings with combustible ceiling or roof construction shall have an attic access opening to attic areas that exceed 30 square feet (2.8m squared) and have a vertical height of 30 inches (762 mm) or more. The rough-framed opening shall not be less than 22 inches by 30 inches, and shall be located in a hallway or readily accessible location. A 30-inch (762 mm) minimum unobstructed headroom in the attic space shall be provided at some point above the access opening.

Tips that inspectors can pass on to their clients:
  • Do not allow children to enter the attic through an attic access. The lanyard attached to the attic stairs should be short enough that children cannot reach it. Parents can also lock the attic ladder so that a key or combination is required to access it.
  • If possible, avoid carrying large loads into the attic. While properly installed stairways may safely support an adult man, they might fail if he is carrying, for instance, a bag full of bowling balls. Such trips can be split up to reduce the weight load.
  • Replace an old, rickety wooden ladder with a new one. Newer aluminum models are often lightweight, sturdy and easy to install.
​
In summary, attic pull-down ladders are prone to a number of defects, most of which are due to improper installation.

Sump Pump Operation & Inspection Guide

4/16/2018

0 Comments

 
Sump pumps are self-activating electrical pumps that protect homes from moisture intrusion. They are usually installed below basement or crawlspace floors to remove rising groundwater and surface runoff before it has a chance to seep into the home. Accumulated water can cause interior damage and encourage the growth of mold, mildew, and fungus. Pumps should be maintained and equipped with all necessary components in order to ensure their reliability.
How a Sump Pump Works 

A pit, known as a sump pit or sump trench, can be dug at the lowest part of the basement floor to capture and contain any flowing water. A sump pump sits at the bottom of this trench (or beside it) and expels excess water through a series of interconnected pipes to a suitable discharge location. The pump can sense water levels through a float that rises and falls with fluctuating water levels in the trench. The sump pump becomes activated and deactivated based on the height of the float, providing a simple, automated way to monitor and deal with variable water levels.
Picture
Types of Sump Pumps
  • Pedestal sump pumps sit above the water line beside the sump trench and are not designed to get wet. Since they are not contained within the sump pit, they can be accessed easily but are also very noisy. They cost roughly $60 to $200, which is significantly less than other varieties.
  • Submersible sump pumps rest underwater at the bottom of the sump pit, and are much quieter than pedestal pumps. Their oil-cooled motors and tight seals protect against water and dust and afford them a long lifespan. They can cost up to $600.
  • Water-powered sump pumps are normally used as backups and kick in when the main pump experiences an electrical or mechanical failure.
Maintenance
  • The pump must be kept clean and free of debris. The inlet screen prevents the passage of dirt and other solid material from entering the pump, but it can become overwhelmed. Cleanings should occur often for pumps that run constantly.
  • Inspectors should make sure that the float is not tangled or jammed in one position. A sump pump with a jammed float is useless because it will not sense when it should turn on and shut off.  
Picture
  • The pump can be tested by pouring water into the pit to make sure it becomes activated and expels the water. The homeowner should seek professional assistance if the pump does not activate.
  • Maintenance should take place annually, and when the home is sold.
  • When testing the pump, no one should ever reach into the pit. The float can be reached and manipulated with a household item such as a golf club (with a rubber handle) or anything else non-conductive that happens to be lying around. 

Inspectors should check for the presence of the following:
  • A GFCI. There is considerable debate among inspectors concerning whether or not a sump pump should be connected to a GFCI. It is possible that a GFCI can prevent electrocution, but it is extremely unlikely that a sump pump will energize water in the first place. It is much more likely that a GFCI will trip during safe conditions and deactivate the sump pump when it is needed. A sump pump is among the most critical of all household appliances, and its deactivation, especially if the tenants are not home, could allow catastrophic building damage. Codes recommend that appliances in basements and crawlspaces be connected to GFCIs to reduce the chance of electrical shock, but this advice is often ignored due to these concerns over nuisance tripping.

  • An alarm. Sump pumps can burn out, lose power, become clogged or misaligned, or malfunction in a variety of other ways. It is valuable to have a warning device installed that will signal water build-up. These alarms can alert homeowners or neighbors of flooding so that it can be resolved before water damage occurs. Alarms are especially important in residences that are not occupied for long periods of time. Inspectors should keep in mind that, while an alarm can be helpful, it is not a requirement.
  • a check valve. This device is the same diameter as the discharge pipe into which it fits and is usually a different color. A check valve should be installed in order to prevent pumped water in the discharge line from re-entering the sump pit when the device is turned off. Without this valve, the pump will have to work twice as hard to remove the same column of water, which causes unnecessary strain to the pump components. A check valve can also prevent the rare yet disturbing possibility that a discharge line connected to a stream or pond will back-siphon into the sump pit.
Picture
  • a backup power source. Power outages are most likely to happen during heavy rains and floods, which are situations when the sump pump is most needed. For this reason, combined with the nuisance-tripping from GFCIs, sump pumps should have a backup power source to rely on. A pump powered by a battery or the home’s water pressure can also be installed as a backup. Installation of a backup power source or backup pump is not a requirement, but can be offered to a client as a recommendation.

  • that the pit that is large enough for the pump. The sump pit does not need to be constructed from any particular material, as long as it is solid and provides permanent support for the pump. It must, however, be large enough to allow the pump room to work properly. Some homeowners use a 5-gallon bucket as a sump pit, but this is insufficient. For most homes, the sump pit should not be less than 24 inches deep and 18 inches wide. One of the most common reasons why sump pumps fail is that the float gets jammed between the pump and the pit because the pit is too cramped.

  • a cover. The sump pit should be covered to prevent water from evaporating into the home.

Discharge Location
​
 Insideout inspectors are not required to check for a proper discharge location. They can note an improper discharge if they see it, but searching outdoors for the discharge is not recommended. The following is good general information that can be passed on to the homeowner:
  • Water must be discharged at least 20 feet from the building.
  • Water should not drain back into the house! Cycling water will place unnecessary strain on the pump and can weaken the structure’s foundation.
  • Water should not drain onto a neighbor’s property without their approval.
  • Many jurisdictions do not permit pumped water into public sewer systems.
  • Pumped water should never drain into a residence’s septic system. Especially during heavy rain, a septic drainfield will become saturated and will struggle to handle the normal flow of water from the house. Additional water from the sump pump can damage the septic system. 

In summary, sump pumps are used to remove excess water from homes that would otherwise cause property damage. There are multiple types, but they all monitor water levels and ensure that they do not rise higher than predetermined levels. Proper maintenance and inspection will ensure pump efficiency and prolong their lifespan.

Inspecting Gutters & Downspouts

4/9/2018

0 Comments

 
Picture
InsideOut Home Inspectors are required to inspect the gutters and downspouts as part of the roof portion of the home inspection.  
Some important factors a home inspector should consider include:
  • that the guttering system is adequately sized to prevent runoff;
  • that the gutters are free of rust, cracks and holes in order to prevent leaking; and
  • that the downspouts divert water 4 to 6 feet away from the home's foundation.
           
A few inches of rain falling on the roof of a house can produce several thousand gallons of water runoff. This runoff must be channeled away from the home's foundation. Otherwise, the excess water can quickly saturate the soil surrounding the building and wick through the foundation to the interior. (See Figure 1 below.) Once inside, this moisture can lead to a variety of problems, including mold and wood rot. Excess moisture can also cause indoor air quality problems. 
Picture
Figure 1:  If not drained away from the house, the volume of water coming off a roof in a large rainstorm can quickly saturate the soil and wick through the foundation into the interior of the building.

Gutter System Basics
Gutter systems consist of two parts: 1) gutter channels that run horizontally along the roof edge to collect runoff; and 2) the downspouts that carry the collected water to grade level. Roofing gutters should slope down toward the downspout at the rate of 1/16-inch per foot, or 1/4-inch per 5 to 10 feet. An angle less than this won't allow water to move effectively, and much more of an angle will cause the water to move at too great a speed, potentially resulting in overflow over end caps and corners. 

In terms of standards, InsideOut home inspectors are not required to measure the amount of gutter slope. To do it accurately would be time-consuming, would require a transit or water level, and would exceed InterNACHI's Standards of Practice. A more practical approach is to make sure that all gutters slope toward the downspout. In judging adequate slope, look for signs of standing water in portions of the gutter away from the downspout, and eyeball the margin against the fascia. 
​
Gutter channels are typically available in 4, 5, and 6-inch sizes. They are referred to by their shape: there are K-style gutters (also known as "ogee" because the shape resembles this molding type); and U-style gutters (or half-round), as shown in Figure 2 below. The style differences are principally aesthetic; there is no substantial difference in performance. Larger sizes conduct more water at a faster rate, provided that there are enough downspouts to drain the gutter channels without overflowing.
Picture
Figure 2:  Standard gutter styles found in building supply centers include the K and U styles. The difference is purely aesthetic.  (Image courtesy of the U.S. Dept. of Energy's Building America Solution Center.

Downspout Basics

Most downspouts are made of the same material as the gutter system, so they tend to suffer from similar problems, but with a few twists -- especially in the area of mechanical damage from proximity to high-traffic areas.
Downspouts should be inspected for:
  • the connection between the downspout and the gutter;
  • proper attachment of the downspout to the structure;
  • leakage in joints (sometimes they will have been installed upside-down);
  • impact damage from doors of vehicles parked nearby; and
  • downspouts that terminate onto another roof surface.
Climate

The following are some climate-specific considerations for different types of gutter systems:
  • Hot-Dry and Mixed-Dry Climates:  Gutters are not required in all dry climates. However, a wide roof overhang will keep occasional runoff away from the home.  As with any structure, the grade at the foundaiton should slope away from the building.  Metal, rather than vinyl, gutters and downspouts are safer in areas susceptible to wildfires. 
  • Hot-Humid and Mixed-Humid Climates:  In areas with heavy rainfall, the gutter and rain leader capacity should be increased. Kickout and diverter flashing will prevent high water volume from spilling over the gutters and running down the exterior walls of the home. 
  • Marine Climate:  In areas that experience high winds and heavy rains, the gutter and rain leader capacities should be increased, especially for large roofs. 
  • Cold and Very Cold Climates:  Depending on the building codes for the jurisdiction, it may be wise to avoid the use of gutters in areas that receive high snow loads.  If gutters are installed, ice buildup inside the gutters during freezing and below-freezing temperatures can lead to ice damming, which can cause moisture intrusion through the roof's sheathing and any unsealed openings.  There are products available at building supply stores that will help prevent Ice Dams from forming.

Tips for Homeowners
​
Inspectors can relay the following tips to their clients to help them properly and safely maintain their home's gutter system:
  • Observe common-sense safety precautions (and enlist a spotter, if available) when using a ladder to reach the gutter system.  Always maintain three point contact and don't over-reach; move the ladder instead.
  • If mounting the roof, wear footwear with gripping treads to prevent slipping.
  • Wear gloves to protect hands and arms from sharp debris, as well as from animals and insects that may be hiding in the gutters. 
  • A gutter scoop is a convenient tool for removing leaves and other debris. 
  • Cleaning gutters can take a substanial amount of water. Place a garden hose in the gutters and downspouts to flush them out, making sure that the water is directed away from the home via the downspouts. This will help reduce the chances of saturating the soil around the foundation. 
  • Covered gutter systems may be effective in preventing excessive debris buildup, but these are not maintenance-free.
  • Homeowners can install a rainwater harvesting system (if allowed in their jurisdiction) that includes a drainage mechanism to handle overflow. 

If the home is surrounded by deciduous trees, they may shed their leaves onto the roof and into the gutters. So, home inspectors should impress upon their clients that regular gutter system maintenance is necessary to prevent moisture intrusion problems.  
​
  The home inspector should also explain to his clients the importance of a properly functioning gutter system, and the potential problems that an undersized or damaged system can create.

Inspecting Generators & Hazards

4/2/2018

0 Comments

 
Homeowners may use a generator to supply electricity to their home in the case of a power outage, either out of necessity or convenience. Inspectors may want to know about generators and the potential hazards they present when improperly wired or utilized.   
​
Generator Types
There are two main types of generators:  permanently installed, standby generators; and gasoline-powered, portable generators. 
 
Standby Generators 

Standby generators typically operate on natural gas or liquid propane. They remain fixed in place outside the home and are designed to supply on-site power to specified circuits through a home's electrical wiring. These generators work in tandem with a manual or automatic transfer switch, which automatically detects an interruption in grid-powered  electricity and ​subsequently transfers over electrical input to the generator.
 The transfer switch suspends input from the generator once it senses that utility-powered electricity has resumed. Generators for small- to medium-size homes are typically air-cooled and employ fans to regulate the temperature inside the unit. Liquid-cooled units are used for the larger energy loads in larger homes.
Picture
Some advantages of standby generators are as follows:
  • They may be turned on manually, or they may be programmed to switch on automatically in the case of a power outage even when no one is home.
  • Power may be supplied for extended periods of time.
  • Hard-wired systems, such as a home's furnace, well pump and air conditioner, may maintain continuous power.
  • Uninterrupted power can be supplied to systems that must remain on continuously, such as medical equipment used for breathing, etc.
Disadvantages of standby generators are as follows:
  • Installation may require a permit.
  • A qualified technician, such as an electrician, is required to install the ATS and to determine the electrical load requirements for the circuits in a home.
  • Routine maintenance is required.
  • Standby generators may be prohibitively expensive.
Portable Generators 

Gasoline-powered, portable generators are typically smaller in size and power capacity than permanently installed generators. They are designed so that corded electrical devices may be plugged directly into them. 
Picture
Gasoline-powered, portable generators are typically smaller in size and power capacity than permanently installed generators. They are designed so that corded electrical devices may be plugged directly into them. 
 
Advantages to portable generators are as follows:
  • Portable generators are versatile. They may be used at home or transported and utilized in remote locations, such as a campground or a construction site.
  • They do not require complicated installation.
  • They typically do not require permits.
  • Portable units are generally less expensive than standby generators.   
Disadvantages of portable generators:
  • Devices that are hard-wired into a home's electrical system cannot be powered by a portable generator if no transfer switch is installed.     
Hazards
  • Portable and standby generators produce dangerous carbon monoxide (CO) gas, which can be deadly if inhaled.
  • Inexperienced installers are exposed to the risk of electrical shock. Only qualified electricians should attempt to install a generator.
  • Overloading a generator may result in reduced fuel efficiency, damage to appliances or fire.
  • Standby generators or their required transfer switches that are incorrectly wired (or missing) may result in "back-feed" -- a hazardous condition in which an electrical current is fed back into the grid -- which could potentially electrocute and kill homeowners, utility workers, and others who are using the same utility transformer. 
  • Connecting a portable generator directly into a home's wall outlet can also cause dangerous back-feed.
  • Generators that are exposed to water or that are not properly grounded can cause electrocution.
  • Gasoline for portable generators is highly flammable and may cause a fire when exposed to an open flame or when spilled on the hot generator.
  • Over-taxed cords attached to a portable generator may cause a fire.
Inspecting A Generator
​
InsideOut inspectors check for the following: 
  • Generators should never be used anywhere indoors, even if the area is ventilated.
  • Portable generators placed outside should not be near doors, vents or open windows leading into the home.
  • Carbon-monoxide detectors should be installed in case CO is accidentally released into the home.
  • A standby generator hard-wired into a home should have a transfer switch installed to prevent backfeeding.  An inspector can locate this device situated between
  • Generators should be properly grounded.
  • Units should be dry and shielded from contact with liquid.
  • Only heavy-duty electrical cords that are rated for outdoor use should be plugged into portable generators.
  • Electrical cords should not have any punctures or exposed wiring.
  • Cords running from portable generators should be kept out of the way of foot traffic and should not run underneath rugs.
  • The total electrical capacity of the generator should exceed the power requirements of the devices that the unit is supplying.
  • Fuel for portable generators should be stored away from the home and children in clearly labeled and durable containers.

In summary, generators can be lifesavers during a power outage, but they present serious health and safety concerns if they are not installed and used properly.

Inspecting for Defects in Older Buildings

3/26/2018

0 Comments

 
While you can’t predict the lurking dangers in an unfamiliar home, its age offers clues about what you can expect to encounter. Older homes, especially those that have remained in the same hands for much (or all) of their lifetime, are often plagued by a common set of defects that InsideOut inspectors and potential home buyers may want to learn about.
Some of the more prevalent issues of older homes are as follows.
  • Lead is a toxic metal that was once commonly used in the manufacture of household paint and plumbing fixtures, and as an additive to gasoline. While it has long been prohibited in new construction, lead-based paint and plumbing that weren't removed may present a significant health hazard. Homes constructed 
prior to 1978 may contain lead paint, which can be ingested by small children or contaminate surrounding soil and vegetable gardens. It is easily identifiable by its alligator-like flaking pattern. Lead pipes, too, were used in homes up until the late 1940s, and they may allow lead to leach into drinking water. They can be identified by their dull gray color and the ease by which they can be scratched by keys or coins.
Picture
  • Asbestos insulation, which can increase the chances of developing lung cancer and mesothelioma, was used in homes between 1930 and 1950. Asbestos insulation should be left undisturbed until it can be removed by a qualified professional, as its fibers can be inhaled when they are airborne, creating a significant health hazard.
  • Older homes were not constructed to meet modern energy efficiency requirements. They may suffer thermal losses from single-pane windows, insufficient or compressed insulation, leaking ductwork, and inefficient heaters and other appliances. It should be noted, however, that older homes better capitalize on natural sources of lighting, heating and ventilation through the use of design features such as exterior shutters, shade trees, and thick, heat-retaining masonry walls.
  • Buried oil tanks were often abandoned and forgotten after homes switched to newer fuel sources. Today, these tanks pose a safety hazard to homeowners and their neighbors, as their contents may leak into surrounding soil. Disposal guidelines vary and may call for removal of the tank or filling it with sand or gravel. Soil testing may be required to investigate whether an abandoned fuel tank has leaked underground.
  • Obsolete electrical components pose a fire and safety hazard, such as:
    • aluminum wiring. From about 1965 to 1973, single-strand aluminum wiring was sometimes used in place of copper branch-circuit wiring in residential electrical systems due to the escalating price of copper. After a decade of use by homeowners and electricians, weaknesses were discovered in the metal, which led to its disuse as a branch wiring material. Although properly maintained aluminum
Picture
                   wiring is acceptable, aluminum will generally become defective faster than copper due to certain qualities                       inherent in the metal. It can be identified by its color or the labels “CO/ALR,” “aluminum” and “AL”;
  • knob-and-tube (K&T) wiring.  This was an early standardized method of electrical wiring in buildings from about 1880 to the 1940s. While codes do not require its removal, K&T wiring often suffers from unsafe modifications, old age, overheating, and lack of a ground wire. It can be identified by its characteristic porcelain insulating tubes;
    • a lack of ground-fault circuit interrupters (GFCIs). Homes built before the 1970s may not have been equipped with GFCI protection, which guards against overloads, short circuits and ground faults; and
    • a lack of grounded receptacles, which provide a safe path to ground for stray electrical current. Most major appliances, such as stoves, refrigerators and computers, have three-prong plugs and require three-slot or grounded receptacles. Homes in the U.S. built before 1962 were not constructed with three-slot receptacles.
  • Wells, cesspools and septic tanks were commonly used before homes and buildings were connected to public sewer and water systems. If they were abandoned and not removed, these elements pose hazards related to their deterioration and collapse.
  • Radon is a naturally occurring gas that has been identified as the second leading cause of lung cancer in the United States. It usually enters the home through cracks in the foundation, a common problem found in vintage construction. Radon cannot be seen, smelled or tasted, so concerned homeowners should consult with their InsideOut inspector about radon testing during their next scheduled inspection.

Arc-Fault Circuit Interrupters (AFCIs)

3/19/2018

0 Comments

 
Arc-fault circuit interrupters (AFCIs) are special types of electrical receptacles or outlets and circuit breakers designed to detect and respond to potentially dangerous electrical arcs in home branch wiring.
How do they work?
 
AFCIs function by monitoring the electrical waveform and promptly opening (interrupting) the circuit they serve if they detect changes in the wave pattern that are characteristic of a dangerous arc. They also must be capable of distinguishing safe, normal arcs, such as those created when a switch is turned on or a plug is pulled from a receptacle, from arcs that can cause fires. An AFCI can detect, recognize, and respond to very small changes in wave pattern.
Picture
What is an arc?
 
When an electric current crosses an air gap from an energized component to a grounded component, it produces a glowing plasma discharge known as an arc. For example, a bolt of lightening is a very large, powerful arc that crosses an atmospheric gap from an electrically charged cloud to the ground or another cloud. Just as lightning can cause fires, arcs produced by domestic wiring are capable of producing high levels of heat that can ignite their surroundings and lead to structure fires.
According to statistics from the National Fire Protection Agency for the year 2005, electrical fires damaged approximately 20,900 homes, killed 500 people, and cost $862 million in property damage. Although short-circuits and overloads account for many of these fires, arcs are responsible for the majority and are undetectable by traditional (non-AFCI) circuit breakers.

Where are arcs likely to form?
 
Arcs can form where wires are improperly installed or when insulation becomes damaged. In older homes, wire insulation tends to crystallize as it ages, becoming brittle and prone to cracking and chipping. Damaged insulation exposes the current-carrying wire to its surroundings, increasing the chances that an arc may occur.
Situations in which arcs may be created:
  • electrical cords damaged by vacuum cleaners or trapped beneath furniture or doors.
  • damage to wire insulation from nails or screws driven through walls.
  • appliance cords damaged by heat, natural aging, kinking, impact or over-extension.
  • spillage of liquid.
  • loose connections in outlets, switches and light fixtures.
Picture
Where are AFCIs required?
 
Locations in which AFCIs are required depend on the building codes adopted by their jurisdiction.
The 2006 International Residential Code (IRC) requires that AFCIs be installed within bedrooms in the following manner:
E3802.12 Arc-Fault Protection of Bedroom Outlets. All branch circuits that supply120-volt, single-phase, 15- and 20-amp outlets installed in bedrooms shall be protected by a combination-type or branch/feeder-type arc-fault circuit interrupter installed to provide protection of the entire branch circuit.
Exception: The location of the arc-fault circuit interrupter shall be permitted to be at other than the origination of the branch circuit, provided that:
  1. The arc-fault circuit interrupter is installed within 6 feet of the branch circuit overcurrent device as measured along the branch circuit conductors, and
  2. The circuit conductors between the branch circuit overcurrent device and the arc-fault circuit interrupter are installed in a metal raceway or a cable with metallic sheath.

The National Electrical Code (NEC) offers the following guidelines concerning AFCI placement within bedrooms:
Dwelling Units. All 120-volt, single phase, 15- and 20-ampere branch circuits supplying outlets installed in dwelling unit in family rooms, dining rooms, living rooms, parlors, libraries, dens, sun rooms, recreation rooms, closets, hallways, or similar rooms or areas shall be protected by a listed arc-fault circuit interrupter, combination-type installed to provide protection of the branch circuit.
Home inspectors should refrain from quoting exact code in their reports. A plaintiff's attorney might suggest that code quotation means that the inspector was performing a code inspection and is therefore responsible for identifying all code violations in the home.  Some jurisdictions do not yet require their implementation in locations where they can be helpful.

What types of AFCIs are available?
 
AFCIs are available as circuit breakers for installation in the electrical distribution panel. 
 
Nuisance Tripping
 
An AFCI might activate in situations that are not dangerous and create needless power shortages. This can be particularly annoying when an AFCI stalls power ​​to a freezer or refrigerator,
allowing its contents to spoil. There are a few procedures an electrical contractor can perform in order to reduce potential “nuisance tripping," such as:
  • Check that the load power wire, panel neutral wire and load neutral wire are properly connected.
  • Check wiring to ensure that there are no shared neutral connections.
  • Check the junction box and fixture connections to ensure that the neutral conductor does not contact a grounded conductor.

Arc Faults vs. Ground Faults
 
It is important to distinguish AFCI devices from Ground Fault Circuit Interrupter (GFCI) devices. GFCIs detect ground faults, which occur when current leaks from a hot (ungrounded) conductor to a grounded object as a result of a short-circuit. This situation can be hazardous when a person unintentionally becomes the current’s path to the ground. GFCIs function by constantly monitoring the current flow between hot and neutral (grounding) conductors, and activate when they sense a difference of 5 milliamps or more. Thus, GFCIs are intended to prevent personal injury due to electric shock, while AFCIs prevent personal injury and property damage due to structure fires.
 
In summary, AFCIs are designed to detect small arcs of electricity before they have a chance to lead to a structure fire. ​

The Dangers of Mold
Molds produce allergens, which are substances that can cause allergic reactions, as well as irritants and, in some cases, potentially toxic substances known as mycotoxins.  Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals.  Allergic responses include hay fever-type symptoms, such as sneezing, runny nose, red eyes, and skin 
rash (dermatitis).  Allergic reactions to mold are common.  They can be immediate or delayed.  Molds can also cause asthma attacks in people with asthma who are allergic to mold.  In addition, mold exposure can irritate the eyes, skin, nose, throat and lungs of both mold-allergic and non-allergic people.  Symptoms other than the allergic and irritant types are not commonly reported as a result of inhaling mold, but can also occur.
Picture
Carpet at Risk
Carpeting is an area of the home that can be at high risk for mold growth.  In order to grow, mold needs moisture, oxygen, a food source, and a surface to grow on.  Mold spores are commonly found naturally in the air.  If spores land on a wet or damp spot indoors that contains dust for them to feed on, mold growth will soon follow. Wall-to-wall carpeting, as well as area rugs, can provide an ample breeding ground for mold if conditions are right.  At especially high risk for mold growth are carpeting located below ground level in basements, carpet in commonly moist or damp climates, and carpet that has been wet for any period of time. 

Identifying Mold in Carpeting
Just because mold is not immediately apparent or visible on a carpet's surface does not mean that mold growth is not in progress.  In fact, mold will probably only be visible on the surface of carpets in unusually severe cases of growth, such as carpet damaged in flooding that has remained wet for some time. InsideOut Inspections can detect specific types of mold spores by using state of the art equipment to pull air samples from your home.  The following are some examples of identifiable instances where mold growth has occurred or is likely to occur:
  • visible mold growth:  As stated above, this can be a rare case, but sometimes it may be obvious from visual inspection that mold growth is occurring.  Carpet in this condition is most likely not salvageable and should be disposed of and replaced.  Often, even if mold growth is not visible on the top of carpeting, it may be occurring underneath the carpet where it can't be easily seen.  Carpet suspected of containing mold should always be examined on both sides.

  • carpet mildew:  Any discoloration or odor on carpeting that might be described as mildew is probably a case of mold.

  • wet or water-damaged carpet:  Any carpet that has been subjected to water damage from flooding or standing water will most likely need to be disposed of.  Conditions are ripe for mold growth, in this case.  Even if visibly apparent mold growth has not yet begun, it is highly likely to happen unless the carpet is completely removed, cleaned and dried within 24 to 48 hours.  Even then, removal and cleaning are not guaranteed to prevent mold growth.  It is more likely that the carpet will need to be replaced.

  • wet padding beneath carpet:  If padding beneath the carpet has become wet for any reason, or has become moist from condensation, the padding as well as the carpet on top are at risk for mold growth.  The padding may need to be replaced, as will the carpet, in some cases.

  • basement carpet:  Carpeting in basements below grade level is especially at risk in areas where humidity is high, or where wide temperature swings can produce condensation.

  • odors and stains:  There is a wide range of things that can cause odors and stains on carpets.  If mold is suspected, samples can be taken and sent for analysis to determine if mold growth has occurred.
Preventing Mold Growth in Carpeting
The best method for combating mold is to not allow mold growth in the first place.  The best way to do so is by ensuring that conditions conducive to growth do not exist.  Below are some ways to prevent mold growth in carpets.
  • Reduce indoor humidity.  The use of dehumidifiers will help control moisture in the air, depriving mold spores of the water they need to grow into mold.  A range of 30% to 60% humidity is acceptable for interiors.

  • Install intelligently.  Do not install carpeting in areas that are likely to be subject to frequent, high moisture.  Carpet in a bathroom, for example, will quickly turn to a breeding ground for mold growth due to the high humidity from constant water use in that area.

  • Choose high-quality carpet padding.  Solid, rubber-slab carpet padding with anti-microbial properties is available.  It is slightly more expensive than other types of padding but can be helpful for preventing the growth of mold, especially in climates prone to periods of high humidity.

  • Never allow standing water.  Carpet exposed to standing water will quickly be ruined.  If standing water ever occurs because of a leak or a spill, all carpeting exposed must be immediately cleaned and dried.  The top and bottom surfaces of the carpet, any padding, and the floor underneath must be cleaned and completely dried within a short period of time after exposure to standing water if the carpet is to be saved.  If a large flood has occurred, or if standing water has been present for any extended period of time, the carpet will probably need to be replaced.

  • Clean smart.  When carpeting needs to be cleaned, try to use a dry form of cleaning, when possible.  If any water, liquid, or other moisture has come in contact with the carpet during cleaning, be sure it is dried thoroughly afterward.

Removing Mold From Carpet
In many cases, if mold has grown on carpet, cleaning will not be possible.  If growth has occurred on more than one area of the carpet, or if there is a large area of growth, the carpet will probably need to be replaced. 
Picture
Small areas of growth that have been quickly identified can sometimes be dealt with.  Detergent and water used with a steam-cleaning machine may be enough to clean the carpet thoroughly.  It is then important to ensure that the carpet dries completely after cleaning to prevent the growth from recurring.  Stronger cleaning agents can be substituted if detergent does not work.  Anything stronger than detergent or common rug-cleaning products should first be tested on an inconspicuous area of the carpet to ensure that the rug will not be damaged during cleaning. 
About 24 hours is a reasonable amount of time to wait after testing to be sure that wider cleaning will not discolor or damage the carpet.
​
Another option in instances where mold growth is not widespread is to remove the ruined section of the carpet.  If cleaning has been attempted unsuccessfully, the area of mold growth may be removed and replaced with a patch of similar carpet.  Of course, this will only work in situations where aesthetics are not a big concern, since exactly matching the patch to the original carpet may be difficult and the seam may be visible.  If mold has grown in more than one area of the carpet, or if the area of growth is larger than a couple of feet, this will probably not be an effective method of mold removal.
 
As with all areas of the interior at risk for mold growth, prevention is the best method of control for carpet mold.  Eliminating high-moisture conditions and preventing the risk of flooding or standing water will reduce the possibility of growth.  Inspectors will want to know where to look for and how to identify mold growth in carpeting.  It is also helpful to know how to determine if carpet should be replaced, or whether there is a possibility of cleaning and saving it.

Carpeted bathrooms are bathrooms that have carpeted floors instead of traditional floor surfaces, such as tile or vinyl. Despite their tendency to foster mold and bacteria, carpets are sometimes installed in residential bathrooms for aesthetic purposes.
Advantages of Carpets in Bathrooms
  • They make bathrooms appear more warm and inviting.
  • They are softer than tile and many people find them comfortable on bare feet.
  • Bathroom slip hazards are reduced. It is easier to slip on hard bathroom surfaces, such as tile, than on carpet.
  • Installation is generally quick and inexpensive.
Carpeted Bathroom
Disadvantages of Carpets in Bathrooms
 
The pad beneath the carpet may soak up large amounts of moisture.  Some of the common ways that carpets may come into contact with moisture in bathrooms include:
  • Steam from the shower will condense on the carpet.
  • Water splashes from the tub or shower.
  • Water sheds from shower/tub occupants as they step onto the carpet.
  • Water splashes out of the sink.
  • Water drips from the vanity.
  • Water leaks from the toilet.
The presence of moisture in the pad will lead to the growth of decay fungi on the wood or oriented strand board (OSB) sub-floor. The sub-floor will be decayed and weakened by mold. Mold also releases spores that can cause respiratory ailments, especially for those with certain health problems. Inspectors can use moisture meters to determine if there is excess moisture beneath a carpet.
​
 In addition to potential mold growth beneath the carpet, bacteria can accumulate in carpeting that surrounds the toilet. Bacteria are contained in urine, which can be accidentally deflected onto the carpet.
 
The following are recommendations that InterNACHI inspectors can pass on to clients who are experiencing urine- or moisture-related problems with their bathroom carpet:
  • Clean the carpet regularly to remove any mold or urine that may be present.
  • Keep the carpet as dry as possible. Various devices exist that prevent water from bypassing the shower curtain.
  • Install a bathroom fan, if one is not installed already. If a fan is installed, operate it more often.
  • Inspectors can inform their clients about why they are experiencing problems.

In summary, carpets installed in bathrooms can trap moisture and urine, substances that can cause structural damage and health problems.

Ceramic Tile and Stone Inspection

2/26/2018

0 Comments

 
Ceramic tile and stone are popular flooring materials, but each is subject to damage if not properly maintained.
Ceramic tile, due to its low required maintenance, ease of cleaning, and resistance to physical damage, is one of the most popular flooring materials available today. Made primarily from clay and other organic, as well as inorganic, materials, the tile is available in both glazed and unglazed finishes. Ceramic tiles are vulnerable to a number of defects, however, that can be inspected for the following issues:
Ceramic Tile
Ceramic Tile
  • uneven tiles. Examine the tiles to see how level they are in relation to each other. Uneven tiles probably weren’t set correctly in the mortar, and reinstallation may be necessary;
  • cracks, loose tiles and splitting. Cracks in ceramic tile are the result of movement in the tile underlayment, excessive expansion or contraction of the building during freeze-thaw cycles, abuse, or improper installation. Minor cracks can be repaired with grout that matches the color of the tile, but larger cracks may require replacement of the tile;
  • crazing. If tiles were cooled too quickly after kiln-firing, they can develop fine surface cracks, most often appearing as a fine, web-like network akin to cracked ice. Crazing is much more common in older, historic tiles than in modern tiles, but it still happens today. Crazing increases the rate at which tiles hold dirt, leading to discoloration; and
  • cracked or discolored grout lines. Unsealed or improperly sealed grout will readily absorb moisture from the air or standing water, especially around showers and sinks. Some types of porous tiles may actually powder or spall if subjected to constant moisture. Damaged or discolored grout can be removed and replaced.
Craving
Natural stone tiles have a beauty that is difficult to recreate. They add an air of elegance and character to any home. Stone is more durable than ceramic tile, too, as it’s less likely to scratch, and holds up well under foot traffic. The unique and complex patterns can appear busy and overwhelming in large, empty rooms, however.  Stone is also more difficult to maintain than ceramic tile. The following maintenance and repair tips are recommended:
  • Apply an impregnating sealant. An oliophobic sealant will repel both oil and water, and it’s especially helpful in the kitchen. Try to use a solvent-based sealant, as they’re generally better than water-based varieties.
  • Quickly clean up any acids. Some of the more common stone tiles are marble and limestone, which are calcite-based, meaning that they will corrode when exposed to acids, such as vinegar or lemon juice. Unfortunately, sealants cannot protect stone against these substances, which will etch into the stone if left standing. Igneous stones, such as basalt and granite, as well as ceramic tile, are less vulnerable to acid damage.
  • Lay walk-off mats or area rugs on either side of exterior entrances and instruct people to wipe their feet before they enter the home. The main cause of surface scratching on stone floors is dirt from outside that becomes caught under shoes and scraped across the floor. Scratching can dull the stone’s natural polish and damage its natural crystals, causing it to lose its shine and reflection.
  • Use a good-quality stone soap, preferably one containing linseed oil, for regular maintenance and cleaning. In most cases, you can simply mop the soap and leave it to dry.​
In summary, ceramic and stone can be superb flooring materials, but water, acid, improper installation, and other adverse conditions may create defects.
