Healthy Homes for West Virginia — Damp Hollows and Radon Pathways
Virtual Home Health Score assessments statewide. GaiaCrete™ detailed for West Virginia's Appalachian elevations and damp valley sites. Founding Mr Hemp House® dealer territories open by ZIP code.
Hollow-country damp and mold
Shaded West Virginia hollows keep foundations and crawlspaces wet year-round, and cool surfaces indoors condense that moisture.
Appalachian radon pathways
Fractured rock and legacy mine workings give soil gas easy routes into West Virginia basements, and testing rates remain low.
Older, mixed-fuel heating stock
West Virginia's aging houses often combine space heaters, wood, and old furnaces, raising combustion-byproduct and ventilation risk in winter.
What Climate Zone 4A-5A Means for West Virginia Homes
West Virginia's Appalachian terrain puts most of the state in Zone 4A with Zone 5A in the higher elevations, and narrow hollows that trap cold air and moisture. Housing is older than the national median and often heated with a mix of fuels. Fractured Appalachian rock and abandoned mine workings make radon and soil-gas pathways a live concern.
West Virginia State Building Code (W. Va. C.S.R. 87-4)
West Virginia adopts the IRC and IECC, with enforcement adopted at the county or municipal level.
