Nicholasville, KY: what's different here
Nicholasville is the seat of Jessamine County, about 11 miles and roughly 17 minutes from Lexington via Nicholasville Road. The Kentucky Geological Survey flags radon as a local problem there, with a few areas of high radon concentrations recorded in the Bluegrass region. The county's Inner Bluegrass karst geology and Tanglewood limestone make radon infiltration into homes one of the listed hazards. Homes in high-radon areas should be tested.
What level of radon requires mitigation?
The EPA's action level for indoor radon is 4 picocuries per liter (pCi/L). The Kentucky Geological Survey says homes in high-radon areas should be tested, and mitigation is needed when levels stay above the EPA guideline. The health threat comes from relatively high exposure over long periods of time.
Why won't radon levels go down after mitigation?
If levels stay high, the system may be undersized, the fan may have failed, or the slab may have unsealed openings. Sub-slab depressurization, a pipe-and-fan system that draws radon from beneath the foundation before it enters the home, is the most effective method. Ask the pro to diagnose the existing system before adding work.
How much does a radon fan cost to run?
An active radon fan draws 100 to 300 watts continuously, adding about $30 to $300 per year to the home's energy bill. Factor that operating cost into your budget. Ask the pro what fan size your home needs.
How do I verify a radon contractor in Kentucky?
Kentucky requires contractors performing radon-related services to be licensed by the state. Verify certification through the state radon office at radon.ky.gov or by calling 502-782-2782. Ask the pro for proof of licence and insurance before work begins.
What to do next
- Retest with a long-term kit to confirm whether levels stay above the EPA's 4 pCi/L action level.
- Verify the contractor's NRPP certification and state licence at radon.ky.gov or by calling 502-782-2782.
- Ask the pro to inspect any existing system's fan, pipe seals, and slab openings before quoting new work.
- Get a written quote that lists the sub-slab depressurization design, fan wattage, and total price.
