Radon is a lung cancer-causing radioactive gas. It is an odorless, tasteless and invisible gas produced by the decay of naturally occurring uranium in soil, rock and water. 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. The EPA recommends that those homes be treated with a radon mitigation system with radon levels of 4 pCi/L and above. We service Western WI and Eastern MN. We are currently offering specials on Radon Testing.

Radon Detection and Reduction questions, answered by experts

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Testing typically costs between $150 and $500, depending on the method used and the number of areas tested.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.
