Healthy Homes for Wisconsin — Deep Cold and High Radon Counties
Virtual Home Health Score assessments statewide. GaiaCrete™ detailed for Wisconsin's Zone 6A-7 design temperatures and Uniform Dwelling Code. Founding Mr Hemp House® dealer territories open by ZIP code.
Very cold design temperatures
Northern Wisconsin's Zone 7 design conditions punish any thermal bridge, and cold interior surfaces are where condensation and mold begin.
High regional radon
South-central and driftless Wisconsin counties report radon levels among the highest in the Midwest, with basements as the entry path.
Winter-long closed-house ventilation
Wisconsin homes stay sealed for six months, so undersized ventilation lets CO2, humidity, and VOCs accumulate.
What Climate Zone 6A-7 Means for Wisconsin Homes
Wisconsin runs Zone 6A across the south and Zone 7 in the northern counties, where design temperatures drop far below zero. The state has some of the highest documented radon levels in the Midwest, concentrated in the driftless and south-central regions. Long winters with tightly closed houses turn any ventilation shortfall into a measurable indoor air problem.
Wisconsin Uniform Dwelling Code (SPS 320-325)
The UDC governs one- and two-family dwellings statewide with Wisconsin-specific energy and ventilation requirements.
Start With Your Home Health Score in Wisconsin
Virtual Healthy Home Assessments available in Wisconsin. In-person coverage expanding.
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.
