Winchester, KY: what's different here

Winchester is the seat of Clark County, Kentucky, about 19 miles and roughly a 30-minute drive from Lexington via the main highway. The area sits on Ordovician, Silurian, and Devonian bedrock, and Kentucky radon potential is strongly tied to bedrock type. Black shale and phosphatic limestones, common uranium-bearing rock types in Kentucky, are part of the state's geology. Central Kentucky's limestone, shale, and phosphatic rock give Winchester a radon context consistent with the region's higher radon concern.

Why does my radon system vent smell in Winchester?

A radon system vent odor is usually a sign the mitigation system may be venting sewer gas, soil gas, or has a fan or piping problem. EPA guidance says any new odor near the pipe or fan discharge is a reason to have the system inspected. Don't ignore a smell that suddenly appears after months of no odor.

How much does radon mitigation cost in Winchester, KY?

Installing a mitigation system in an existing home usually costs between $800 and $2,500. A national-style Lexington cost guide puts the average between $1,200 and $3,000. EPA guidance says most homes can be fixed for about the same cost as other common home repairs.

Who should fix a radon system vent odor in Winchester?

The EPA says radon mitigation work should be done by a certified or qualified radon mitigation contractor. Kentucky does not license radon contractors at the state level, so homeowners are directed to nationally certified professionals through the NRPP or NRSB directories. You can verify contractors through the state radon office at radon.ky.gov or 502-782-2782.

Does Winchester, KY have high radon potential?

Winchester sits in Clark County on Ordovician, Silurian, and Devonian bedrock, and Kentucky radon potential is strongly tied to bedrock type. The Kentucky Geological Survey notes that black shale and phosphatic limestones are common uranium-bearing, high-radon-potential rock types in the state. Since the KGS radon potential map is based on bedrock type, individual home testing is still necessary.

How well does mitigation lower radon levels?

EPA guidance says home radon levels can be lowered by as much as 99% with proper mitigation. A typical job is often completed in about 1 day, though complex foundation layouts can take longer. Running the fan adds about $30 to $300 per year to your energy bill, since it draws 100 to 300 watts continuously.
