What is radon?
Radon is an extremely toxic gas that is produced when soil, rocks and water break down. Since rocks, soil and water are always in the process of decaying, radon is continuously emitted. Radon gas is colorless, tasteless and odorless and is present in all soil, although levels can vary in different soil compositions. How much radon escapes from the soil is determined by the soil porosity and chemistry, soil moisture level and weather conditions. The amount of radon that enters your house depends upon the factors just listed combined with the amount of suction (vacuum) created by your particular house.

How does radon get into my house?
Any home may have a radon problem. Radon is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up. Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements. Radon from soil gas is the main cause of radon problems. If your test shows radon levels lower than 4 pCi/L, this is within the range of safety. It is very important, however, to repeat testing in order to insure continuing safe levels. The EPA recommends testing your home every two years and to test any time you change an area of activity to a lower level in your home, or any time you do any major renovations or have new systems installed, such as plumbing, furnace or central air.

If we have elevated levels of radon, that is, over 4 pCi/L, what should our next step be?
As soon as possible, select a qualified radon mitigation contractor to implement a radon reduction system in your home. The contractor will design the most effective system for your home’s structure and foundation. When the system is in place be sure to maintain the radon reduction system according to the contractor’s instructions.

How much does a radon mitigation system cost?
Radon reduction systems work. Some radon reduction systems can reduce radon levels in your home by up to 99%. The cost of fixing a home generally ranges from $800 to $2,500 (with an average cost of $1,400). Your costs may vary depending on the size and design of your home and which radon reduction methods are needed. Hundreds of thousands of people have reduced radon levels in their homes successfully.
