What Wisconsin requires
Wisconsin does not require a specific mold remediation license. Contractors should hold a valid Wisconsin Dwelling Contractor or home improvement credential as applicable. Homeowners should look for IICRC-certified professionals with proper insurance and experience handling Midwest humidity and moisture issues.
Standard homeowner insurance in Wisconsin generally covers mold from sudden water damage events. Wisconsin's humid summers and cold winters, which can cause ice dams and condensation, create conditions for mold growth. Most policies exclude mold from gradual moisture problems.
