Radon is a gas you cannot see, smell, or taste — and Colorado has a lot of it. The only way to know about your house is to test your house.
Call (720) 764-6365Radon rises naturally out of the ground and can collect inside a house — in the basement, in the living spaces, in the air your family breathes every day. You cannot detect it with your senses, and you cannot guess it from the house next door: two homes on the same street can test completely differently. The only honest answer about radon in a particular house comes from testing that particular house.
Colorado soil produces a lot of radon, and that includes Centennial, Littleton, Highlands Ranch, Greenwood Village, Englewood, Parker, Lone Tree, and Cherry Hills. If you are buying, the inspection window is the natural moment to test — you learn the number before the house becomes yours, while it can still be part of the conversation. If you already own, testing is simply how you find out what your family has been living with. Either way, a test turns an invisible question into a known answer, and known answers can be dealt with.
The radon test is separate from the home inspection, and the simplest way to get it is to ask when you book a buyer inspection or a pre-listing inspection — it happens as part of the same visit to the house.
