Radon Resources

Tennessee Has Some of the Highest Radon Levels in the U.S.

Large areas of Middle and East Tennessee—especially Davidson, Williamson, Rutherford, Knox, and surrounding counties—are classified as Zone 1 (highest potential), meaning homes frequently test above the EPA action level of 4.0 pCi/L.

Radon Is the #2 Cause of Lung Cancer in the U.S.

The EPA estimates 21,000+ deaths annually are linked to radon exposure. It is the leading cause of lung cancer among non-smokers, making testing a critical part of a complete home inspection.

Radon Enters Through the Foundation—Not the Air Outside

Radon is drawn into homes through cracks in slabs, crawlspaces, sump pits, and gaps around plumbing. Even brand-new homes or well-sealed homes can develop elevated levels due to pressure differences in the soil beneath the structure.

Radon Mitigation Is Affordable and Highly Effective

Professional mitigation systems typically reduce radon levels by up to 99%, often costing less than other major home repairs. Tennessee homes with basements and crawlspaces benefit significantly from sub-slab or sub-membrane depressurization systems.
