What should we do today while waiting for mitigation?
EPA says there is no known safe level of radon, so reducing exposure matters now. Increase ventilation by opening windows and running fans where safe, and avoid spending extended time in the lowest level of the home. Schedule mitigation as soon as practical rather than waiting for a later test.
How do I confirm the contractor is qualified?
Kentucky law says no person or business may conduct radon mitigation without the appropriate certification. Check the state's certified radon professional listing and ask the pro for proof of certification. Verify the installer's experience, references, and licenses before signing.
What does a mitigation system do?
A common method is sub-slab depressurization, which uses a fan and vent pipe to pull radon from beneath the foundation and exhaust it outside. A qualified contractor can study the home and choose the right system. EPA says typical costs range from about $500 to $2,500.
When should the home be retested after installation?
Retest between 24 hours and 30 days after installation to confirm the reduction worked. If the system is installed in warm weather, retest again in winter between November 1 and March 31.
What to do next

- Verify the contractor's Kentucky radon certification through the state certified radon professional listing before any work starts.
- Request proof of certification, experience, and references from the pro before signing.
- Schedule a retest 24 hours to 30 days after installation to confirm levels dropped below 4 pCi/L.
