Radon In Your Home

Radon can be found all over the U.S. Radon comes from the natural breakdown of uranium in soil, rock and water and gets into the air you breathe. New Hampshire is a prime location due to the amount of granite in our state. It can find its way into any type of building — homes, offices, and schools — and result in a high indoor radon level. But your greatest exposure will be in your home, where you spend most of your time. Testing is the only way to know if you and your family are at risk from radon. EPA and the Surgeon General recommend testing all homes below the third floor for radon. Testing is inexpensive and easy — it should only take a few minutes of your time. Radon levels can be brought into safe ranges with a radon mitigation system. Some radon reduction systems can reduce radon levels in your home by up to 99%. Even very high levels can be reduced to acceptable levels. For more information on radon, testing and mitigation please click the link below.

Attic Ventilation 101

Attic ventilation relies on the principle that hot air rises and cold air falls. Soffit vents allow air intake into the attic space, and ridge, gable, and roof vents allow the hot air to escape. This creates a circular flow which helps prevent hot moist air from causing mold and rot. Proper ventilation also help reduce heating and cooling costs. There is an excellent video in the link below explaining the basic principles in attic venting.

Keeping your dryer vents clean, simple but important maintenance!

Something I always educate my clients on is dryer venting and proper maintenance. Lint is extremely flammable and every year there are approximately 300 fires in the U.S. attributed to dryers and dryer venting. This is an excellent article about installation and maintenance of your dryer venting.

Ungrounded Outlets

 
In older homes the original wiring did not have a ground wire connected to the outlets. These ungrounded outlets are easily distinguished by their two hole / slot configuration verses the newer grounded type of outlet that has three holes / slots. Ungrounded outlets that have two holes / slots used in a home that was originally wired in this manner and has not been rewired are considered acceptable.

The problems for the owners of older homes start when grounded type outlets are substituted for the ungrounded type without the necessary rewiring that adds a ground wire to the new three prong grounded type outlet. Grounded type (three hole / slot) outlets may not be substituted for ungrounded outlets unless a ground wire is connected.

An exception to this rule is allowed by the National Electric Code, when the outlet is protected by a ground fault interrupter (GFI or GFCI).

There is a correction available for those home owners who do not want to rewire the entire house.  Replace the outlets with Ground Fault Interrupters. There are two types of GFI available, one takes the place of the regular circuit breaker in the load center. The second type that is available takes the place of the standard outlet and replaces it with a special GFI protected outlet. These are commonly used in the kitchens and bathrooms of newer homes. Most people know them for their black and red reset buttons.

A surge protector plugged into an ungrounded outlet will not operate as the manufacturer intended. When a large surge or spike hits, the surge protector uses the ground wire to take the "hit" away from the protected equipment and send it safely to ground. If the surge or spike is not sent to ground by the surge protector it will destroy the delicate electronics you were trying to protect. The warranty offered by the surge protectors manufacturer offer, is only valid if the surge protector is used in a properly grounded outlet.

 

 

Garage Door Safety

Automatic garage doors are required to come equipped with safety features to prevent accidental injury. One of the most important features is auto reverse. The door opener should sense an obstruction and stop and reverse. This prevents rhe door from exerting downward pressure and crushing anything trapped under it. As home inspectors we test these functions, and as a home owner you should do the same. For more information on the safety features and methods for testing please click the link.

Plumbing Traps, Knowing Right From Wrong

 Why we want P-traps vs. the old style S-traps.

 An S-trap is obsolete and illegal because as the water leaves it, it can cause a condition called back syphonage, it pulls all the water out of the trap, leaving a dry trap. Dry traps let sewer gases flow back up through the fixture into the house. P-traps are designed to prevent syphonage. The trap retains a small amount of water after the fixture's use. This water in the trap creates a seal that prevents sewer gases from passing from the drain pipes back into the home.
