Mold Remediation & Assessment in Richmond Hill, NY

Yes. New York requires a licence for projects greater than 10 square feet (definitional — Labor Law §930(6)) (N.Y. Labor Law §930(6)). Verify any licence at the official lookup. Also: 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.

4 of the 5 licensing jurisdictions bar the same party from assessing and remediating the same property or project: Texas, Florida, New York and Louisiana. District of Columbia does not — the rule there is disclosure of conflicts and a bar on working where the licensee has a financial interest, not a prohibition on holding both roles. Where no mold licence exists, nothing stops one firm doing both — using an independent assessor is then your own protection against a contractor writing the scope of work they will be paid to perform.
