Radon Detection and Reduction questions, answered by experts

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.

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

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.
