You failed a radon test in Lexington
An elevated result across the Inner Bluegrass is an expected outcome in karst terrain. Confirm the number, get licensed bidders in front of it, and negotiate from a written design rather than a phone estimate.
Bluegrass homeowners ask about karst and sinkholes, and about whether a crawlspace needs treating. Both are real questions with real answers: karst explains the regional pattern without predicting an address, and a crawlspace in soil contact absolutely needs treating. Horse-farm owners ask about outbuildings and apartments over barns, which deserve their own measurements.
What an elevated result actually means
Confirm in the same location under closed-building conditions, and if the original test fell during a wet spell, that confirmation genuinely adds information in karst ground. If a sale is running, confirm and quote in parallel to protect the inspection window. Kentucky licenses the professionals who do this work but does not compel a seller to install a system at any concentration — the result is a disclosure item and a negotiable repair, and a written quote is what makes the negotiation concrete. Closed-house conditions from December through March give the most conservative readings, and Kentucky’s heating season produces solid stack effect. Karst ground responds quickly to rainfall, and the region gets substantial rain — a borderline reading taken during a wet stretch is a good candidate for confirmation rather than immediate action.
Your next four steps
Four steps, in this order. Confirm the result — a second short-term test or a longer-term measurement, run under closed-building conditions. Get written quotes from independent businesses holding a current Kentucky Department for Public Health radon mitigation license. Decide who pays, which in Kentucky is a negotiation and not a legal mandate. Then verify with a post-mitigation test after the system runs. Nothing about a single elevated reading forces you out of your house or out of a contract. Ask for the post-mitigation measurement after twenty-four hours of runtime, in the original detector location, in writing with the Kentucky Department for Public Health license number on the same page. On a crawlspace membrane system, confirm the verification was measured in the living space above rather than in the crawl itself.
If the result landed inside a deal
Kentucky’s seller disclosure form addresses known environmental conditions and hazards, and radon findings a seller knows about belong in that disclosure. Kentucky does not require a seller to test or to mitigate — the response to an elevated result is negotiated. Given regional levels, buyers should treat radon testing as standard diligence during the inspection period.

Failed Radon Test questions in Lexington & the Bluegrass
Does Kentucky require a licensed professional to do the mitigation?
Kentucky licenses radon measurement and radon mitigation professionals through the state Department for Public Health, and that license is what you should verify before hiring — ask for the number, confirm it is current, and confirm it covers mitigation rather than measurement alone. The license is the credential; the written design and the post-mitigation test are how you judge the work.
Does an elevated result put a sale in Lexington at risk?
Kentucky licenses radon measurement and mitigation professionals through the state Department for Public Health, so there is a genuine credential to verify. Kentucky sellers complete a property condition disclosure, and radon appears in inspections routinely. Nothing in Kentucky law compels a seller to test or to mitigate at any concentration.
Am I legally required to mitigate in Kentucky?
No. A result at or above 4 pCi/L is an EPA action recommendation, not an automatic legal obligation in a Kentucky sale. What state law generally governs is disclosure — telling a buyer what you know — not whether a system gets installed. Who pays, and whether the work happens before closing, is negotiated between buyer and seller.
