Mold Remediation in Connecticut: common questions
Is mold remediation licensed in Connecticut?
Connecticut 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 Connecticut, the credentials to check are IICRC certification, general contractor licensing where applicable, and insurance.
What certifications do Connecticut mold remediation firms actually hold?
Across the 56 Connecticut firms on file for this work, the most common credentials are WRT (Water Damage Restoration Technician) held by 40 firms, AMRT (Applied Microbial Remediation Technician) held by 37 firms, ASD (Applied Structural Drying Technician) held by 32 firms, FSRT (Fire and Smoke Damage Restoration Technician) held by 32 firms. 36 hold three or more certifications. Certification describes verified training rather than the services a firm chooses to advertise.
How were these Connecticut firms verified?
Every certification was checked against IICRC's own Certified Firm registry, not against the firm's marketing. 27 of the 56 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026.
