9 certified mold remediation firms in Medford, NY
Ordered by verified credentials only — cross-verified firms first, then active state licences, then breadth of certification. Payment never affects this order.
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.
Can my mold inspector also do the remediation?
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.

Why this is on the page: older housing has had longer to accumulate water events, and its plumbing and building envelope are closer to end of life — so age is a reasonable proxy for how often local firms meet older construction, not a statement about any individual property. It does not mean older homes have mold.
