Radon enters buildings through cracks in foundations, gaps around pipes, and other openings in contact with the soil. The EPA recommends testing for radon in all homes and taking action if levels exceed 4 picocuries per liter (pCi/L). Many states require sellers to disclose known radon test results, and some require disclosure of radon hazard information. Radon mitigation systems can reduce levels effectively and typically cost $800-$2,500 to install.
A home inspection reveals radon levels of 6 pCi/L in the basement, above the EPA action level of 4 pCi/L. The buyer requests a radon mitigation system as a condition of the purchase. The seller installs a sub-slab depressurization system for $1,500, reducing radon levels to 1.2 pCi/L.
Know that the EPA action level for radon is 4 pCi/L. Radon is a naturally occurring gas, not a man-made pollutant. It is the second leading cause of lung cancer (after smoking). Sellers must disclose known radon test results in most states. Radon is MITIGABLE—it can be reduced to safe levels.
