Versailles, KY: what's different here
Versailles is the seat of Woodford County, Kentucky, about 17 miles and roughly 22 minutes from Lexington via US-60 W (Versailles Road). Kentucky radon materials note that certain types of rock emit higher levels of radon, and county-specific maps are based on geology and actual radon values. Woodford County homeowners can check those maps when planning a build. Since Kentucky does not mandate radon-resistant techniques for all new homes, Versailles builders add them by choice.
What does radon resistant new construction cost in Versailles?
The EPA says radon resistant new construction typically costs a builder $250 to $750, and can drop under $250 if moisture-control techniques are already used. A Kentucky radon report puts the cost at roughly $600 to $800 for a single-family home. Either way, it is far less than the $1,200 to $2,500 typically spent fixing an existing home.
What does a passive radon system include under Kentucky standards?
Kentucky Housing Corporation minimum design standards require a perforated collector under the sub-slab or in the crawl space, vented through the roof. Electrical provisions must also be roughed in for a possible future inline fan in the attic or chase. KHC policy requires a passive radon reduction venting system in newly constructed single-family units in covered programs.
How well does radon resistant new construction work?
A Kentucky radon report says RRNC can decrease a home's radon level by up to 50%. If high radon levels are found later, a certified mitigator can easily activate the passive system by adding a fan. Kentucky uses 4.0 pCi/L as the threshold above which mitigation is required.
Who installs radon resistant new construction in Versailles?
Kentucky requires contractors performing radon-related services to be licensed by the state, and the pros we refer are Kentucky-certified (NRPP/NRSB). You can verify radon work through the state radon office at radon.ky.gov or 502-782-2782. Kentucky does not require radon-resistant techniques for all new homes, so ask your builder to include them.
What to do next
- Ask your builder for an itemized quote showing the RRNC line item, expected between $250 and $800.
- Request a passive system with a perforated sub-slab collector vented through the roof, per KHC minimum design standards.
- Ask that electrical provisions be roughed in for a future inline fan in the attic or chase.
- Verify any contractor's radon license through the state radon office at radon.ky.gov or 502-782-2782.
