What our vetted contractors plan for in Minnesota and Wisconsin homes.
Extreme Cold Climate Requirements
Minnesota and Wisconsin require higher R-values than most of the country. Attics need R-49 to R-60, walls R-20 to R-25, and basements R-15 minimum. Our contractors know local code requirements and install insulation systems that actually perform in subzero temperatures.
Ice Dam Prevention
Inadequate attic insulation and air leaks cause ice dams that destroy roofs and gutters across the Upper Midwest. Our professionals install proper insulation depth, seal air leaks, and ensure adequate ventilation to keep your roof cold and prevent damaging ice buildup.
Moisture and Condensation Control
Cold climates create significant condensation risks when warm indoor air meets cold surfaces. Our installers use proper vapor barriers, air sealing, and ventilation strategies to prevent moisture damage, mold growth, and insulation failure.
Existing Home Challenges
Many older Minnesota and Wisconsin homes have settled insulation, missing coverage, or outdated materials. Our contractors identify problem areas, remove old insulation when necessary, and upgrade homes to modern efficiency standards without major renovation.
