Radon Detection and Reduction questions, answered by experts

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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.
