Mold Remediation in Missouri: common questions
Is mold remediation licensed in Missouri?
Missouri 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 Missouri, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
What certifications do Missouri mold remediation firms actually hold?
Across the 66 Missouri firms on file for this work, the most common credentials are AMRT (Applied Microbial Remediation Technician) held by 63 firms, WRT (Water Damage Restoration Technician) held by 63 firms, FSRT (Fire and Smoke Damage Restoration Technician) held by 55 firms, ASD (Applied Structural Drying Technician) held by 49 firms. 58 hold three or more certifications. Certification describes verified training rather than the services a firm chooses to advertise.
How were these Missouri firms verified?
Every certification was checked against IICRC's own Certified Firm registry, not against the firm's marketing. 2 of the 66 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026.
