Mold Remediation in New York: common questions

Do I need a licensed mold remediation contractor in New York?

New York requires a licence for projects greater than 10 square feet (definitional — Labor Law §930(6)) (N.Y. Labor Law §930(6)), issued by NYS Department of Labor — Mold Program (Labor Law Art. 32). Labor Law §936(2) bars a licensee from performing both mold assessment and mold remediation on the same property — the statute's word is property, not project — and requires an independent written assessment before remediation begins.

What certifications do New York mold remediation firms actually hold?

Across the 1,879 New York firms on file for this work, the most common credentials are WRT (Water Damage Restoration Technician) held by 167 firms, FSRT (Fire and Smoke Damage Restoration Technician) held by 138 firms, ASD (Applied Structural Drying Technician) held by 125 firms, AMRT (Applied Microbial Remediation Technician) held by 106 firms. 143 hold three or more certifications. Certification describes verified training rather than the services a firm chooses to advertise.

How were these New York firms verified?

Every certification was checked against IICRC's own Certified Firm registry, and every licence against the NYS Department of Labor — Mold Program (Labor Law Art. 32) file, not against the firm's marketing. 199 of the 1,879 appear in two independent registries and carry a cross-verified marker. Checked August 14, 2026. Where a state publishes only current licensees, a firm absent from that file is reported as absent — never as unlicensed.
