Radon is a dangerous gas you cannot see, smell, or taste, and it is the 2nd leading cause of lung cancer in the U.S.

Any home, new or old, can have a radon problem. Winter is an ideal time to test for radon gas in your home. Closed windows and doors help to create ideal conditions for testing indoor air for radon. Testing should be done on the lowest floor of your home where you or your family spends time or sleeps.
