Mold Remediation in Colorado: common questions
Is mold remediation licensed in Colorado?
Colorado 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 Colorado, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
What certifications do Colorado mold remediation firms actually hold?
Across the 105 Colorado firms on file for this work, the most common credentials are WRT (Water Damage Restoration Technician) held by 103 firms, AMRT (Applied Microbial Remediation Technician) held by 101 firms, FSRT (Fire and Smoke Damage Restoration Technician) held by 83 firms, OCT (Odor Control Technician) held by 73 firms. 99 hold three or more certifications. Certification describes verified training rather than the services a firm chooses to advertise.
How were these Colorado firms verified?
Every certification was checked against IICRC's own Certified Firm registry, not against the firm's marketing. 3 of the 105 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026.
