Mold Remediation in Oregon: common questions
Is mold remediation licensed in Oregon?
Oregon 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 Oregon, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
What certifications do Oregon mold remediation firms actually hold?
Across the 64 Oregon firms on file for this work, the most common credentials are AMRT (Applied Microbial Remediation Technician) held by 64 firms, WRT (Water Damage Restoration Technician) held by 64 firms, ASD (Applied Structural Drying Technician) held by 43 firms, FSRT (Fire and Smoke Damage Restoration Technician) held by 41 firms. 53 hold three or more certifications. Certification describes verified training rather than the services a firm chooses to advertise.
How were these Oregon firms verified?
Every certification was checked against IICRC's own Certified Firm registry, not against the firm's marketing. 52 of the 64 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026.
