What radon level means you should fix the house?
The EPA says a level of 4 pCi/L or higher means the home should be mitigated. Lexington sits in EPA Radon Zone 2, where average indoor screening levels fall between 2 and 4 pCi/L. Because of that, a high reading in a Lexington home is worth taking seriously.
Should I confirm the test with a certified tester?
EPA guidance says all radon tests should run a minimum of 48 hours. For real-estate transactions, a certified radon tester is often recommended instead of a do-it-yourself kit. Ask who ran the original test and whether it met that duration.
What does a radon mitigation system involve?
The usual fix is an active soil depressurization system, which uses a fan and pipe to draw radon from under the foundation before it enters the home. Radon repairs take 24 hours to take effect before re-testing should occur.
How can I get free radon test kits in Lexington?
The Lexington-Fayette County Health Department provides free short-term radon test kits upon request. Its Environmental Health office is at 650 Newtown Pike, and questions can go to 859-231-9791.
What to do next
- Ask the seller or buyer's agent for the original radon test report, and confirm it ran at least 48 hours.
- If the level is 4 pCi/L or higher, request mitigation before closing or schedule it right after you move in.
- Verify the contractor's Kentucky certification on the state radon program list ([email protected], 502-782-2782) before hiring.
- Ask the pro for proof of licence and insurance, and get a written quote that states foundation type and total price.
