Winchester, KY: what's different here
Winchester is the seat of Clark County, Kentucky, about 19 miles and roughly 30 minutes by car from Lexington via the main highway. Clark County is identified as EPA Radon Zone 1, a high radon-potential part of the state. Central Kentucky's risk is tied to Ordovician-age limestone and karst terrain that can let radon move through underground pathways into homes. That makes a pre-sale radon test a common step for Winchester sellers.
Is radon testing required to sell a home in Winchester, KY?
Kentucky does not require radon testing at the time of sale. However, if testing has occurred, the seller must disclose the results on the real estate disclosure form. Many sellers test anyway because only a small share of Kentucky homes have been tested.
How long does radon testing for a home sale take?
For real estate transactions, testing should be conducted by professionals and can be part of a regular home inspection. Professionals can complete a short-term test in as little as 48 hours. That fits most closing timelines.
What if the Winchester home tests above 4.0 pCi/L?
The EPA action level for radon is 4.0 pCi/L. If a home tests at or above that level, mitigation is needed to reduce indoor radon below 4.0 pCi/L. A mitigation system in the Lexington area averages $1,200 to $3,000.
How can I get a free radon test kit in Kentucky?
Kentucky residents can request free radon test kits through the Kentucky Radon Program, and some local health departments also provide free kits. The state program offers free kits if a county does not have its own radon program. Note that a sale transaction should use professional testing.
What to do next
- Order a short-term professional test for the sale, or request a free kit through the Kentucky Radon Program to check your home first.
- Verify the contractor's Kentucky license and NRPP certification through the state radon office at radon.ky.gov or 502-782-2782.
- Ask the pro for proof of license and insurance, and get a written quote covering test results and any mitigation cost.
- If the home tests at or above 4.0 pCi/L, get a mitigation quote and plan disclosure before closing.
- Call (859) 249-8571 or email [email protected] for a free quote from a Kentucky-certified (NRPP/NRSB) radon mitigation contractor.
