U.S. Environmental Protection Agency guidance on testing homes for radon and fixing a problem when levels are high.
The U.S. Environmental Protection Agency explains what radon is, how it can enter homes and how to test for it. Radon is a natural gas that comes from the ground and can collect in basements and crawl spaces, and the agency recommends testing and fixing a home with elevated levels. Waterproofing work touches the same cracks, sumps and slabs that soil gas uses, so Nashville homeowners are often interested in how the two topics connect.
We are a private waterproofing company and are not part of the EPA. We send you to the official pages to read about testing and action levels, and we coordinate with qualified radon professionals when a system is needed. We do not diagnose health risks, and we encourage you to read the guidance and talk with your doctor with any concerns.
