Mold Remediation in Michigan: common questions
Is mold remediation licensed in Michigan?
Michigan does not run a mold-specific licensing program. Only five US jurisdictions do (Texas, Florida, New York, Louisiana and the District of Columbia; Illinois has enacted a program that is not yet in force). In Michigan, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
What certifications do Michigan mold remediation firms actually hold?
Across the 155 Michigan firms on file for this work, the most common credentials are WRT (Water Damage Restoration Technician) held by 151 firms, AMRT (Applied Microbial Remediation Technician) held by 150 firms, FSRT (Fire and Smoke Damage Restoration Technician) held by 125 firms, ASD (Applied Structural Drying Technician) held by 121 firms. 144 hold three or more certifications. Certification describes verified training rather than the services a firm chooses to advertise.
How were these Michigan firms verified?
Every certification was checked against IICRC's own Certified Firm registry, not against the firm's marketing. 4 of the 155 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026.
