Healthy Homes for Kentucky — Cave Country Radon and Flash Floods
Virtual Home Health Score assessments statewide. GaiaCrete™ detailed for Kentucky's Zone 4A climate and statewide residential code. Founding Mr Hemp House® dealer territories open by ZIP code.
Cave-country radon and soil gas
Kentucky's karst limestone conducts radon efficiently into basements, and many counties report averages above the EPA action level.
Flash flooding in eastern counties
Steep eastern Kentucky drainages flood fast, saturating floor systems and wall bases that then dry too slowly to prevent mold.
Cold-damp winters in older stock
Kentucky's older housing has little air sealing, so humid indoor air condenses inside walls through the heating season.
What Climate Zone 4A Means for Kentucky Homes
Kentucky's Zone 4A climate delivers humid summers and cold-damp winters over some of the most extensive karst terrain in North America. Cave-country geology moves both water and soil gas quickly, which shows up as wet basements and elevated radon in the same houses. Eastern Kentucky adds steep terrain and repeated flash-flood exposure.
Kentucky Residential Code (KRC) and Kentucky Building Code
Kentucky adopts the IRC and IECC statewide through the Department of Housing, Buildings and Construction, with mandatory statewide application.

Healthy Home Assessment
A professional walkthrough of materials, moisture conditions, and ventilation, delivered as a prioritized action plan. Screening and guidance — not a medical or diagnostic service.
