    Healthy Homes for Michigan — Lake Snow, Ice Dams, Damp Basements

    Virtual Home Health Score assessments from Monroe to the Keweenaw. GaiaCrete™ detailed for Michigan's Zone 5A-6A heating loads and lake humidity. Founding Mr Hemp House® dealer territories open by ZIP code.

    • Lake-effect snow load and ice dams

      Western and northern Michigan take heavy lake-effect snow, and heat loss through the roof plane turns that into ice dams and wall-top wetting.

    • Lake-humid summers

      Great Lakes moisture keeps Michigan summers humid enough that basements sweat and finished lower levels grow mold.

    • Aging metro housing stock

      Detroit-area homes built before modern materials rules carry legacy finishes and no designed ventilation, so tightening them without a plan raises exposure.

    What Climate Zone 5A-6A Means for Michigan Homes

    Michigan is surrounded by the Great Lakes, which moderate temperature but load the air with moisture and pile lake-effect snow on the western and northern counties. Zone 5A gives way to Zone 6A in the north and Upper Peninsula, where heating seasons are long and deep. Detroit's older housing stock carries a separate set of legacy-material and ventilation problems.

    • Michigan Residential Code and Michigan Uniform Energy Code

      Michigan adopts IRC- and IECC-based codes statewide through LARA, with periodic state amendments.
