Healthy Homes for Ohio — Basement Radon and Snow-Belt Winters
Virtual Home Health Score assessments statewide. GaiaCrete™ detailed for Ohio's Zone 5A heating season and freeze-thaw exposure. Founding Mr Hemp House® dealer territories open by ZIP code.
Glacial-till radon
Much of Ohio sits on radon-bearing glacial deposits and shale, and with basements nearly universal the exposure pathway is short.
Lake Erie snow and freeze-thaw
Northern Ohio's snow belt drives repeated freeze-thaw cycling that opens masonry joints and lets water into wall bases.
Industrial-corridor particulate
Homes near Ohio's older industrial corridors pull outdoor particulate through leaky envelopes and unfiltered ventilation.
What Climate Zone 5A Means for Ohio Homes
Ohio's Zone 5A climate runs from lake-effect snow along Erie down to the humid Ohio River valley. Radon is elevated across much of the glaciated western half of the state, and basements are standard construction. Legacy industrial corridors around Cleveland, Toledo, and the Mahoning Valley add outdoor particulate that leaky houses import.
Ohio Residential Code (OBC/RCO)
Ohio adopts IRC- and IECC-based residential and energy provisions through the Board of Building Standards.

Home Health Score
A free screening that scores your home across indoor air quality, moisture and mold risk, building materials, and ventilation — so you know where to look first.
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.
