Mold licensing in Michigan
Michigan does not license or certify mold remediators or mold testing companies, according to the Department of Health and Human Services, which also does not recommend routine mold testing. Mold work that involves repairs or construction may fall under builder or contractor licensing rules. Ask a company for details in writing, and check the state and local agency sites for current requirements.
