If the Mold Followed a Leak
Stop the water at the fixture valve or the main, cut power to wet rooms at the breaker if you can reach the panel safely, move what you can out of the water, and photograph everything before it is touched. Water that has reached carpet pad, drywall or a subfloor is a same-day restoration call rather than a cleanup: mold can establish on wet materials within 24–48 hours, and every hour of delay moves materials from "dry it" to "replace it."
Before You Sign Anything
Ask for a written scope and the pricing basis, who is fixing the water source and when, and what the moisture readings are — a company that does not take readings is not drying. Sudden, accidental water damage (a burst pipe, a failed supply line, an appliance leak) is usually covered by homeowners insurance; long-term leaks, neglected maintenance and rising outside water usually are not. Document first, then call the restoration company, then the insurer.

New York Labor Law Article 32 (the Toxic Mold Protection Act, effective 2016) created statewide licensing requirements for anyone who inspects, assesses, or remediates mold in residential properties. New York City has additional local licensing through the Department of Consumer and Worker Protection (DCWP).
Contractors performing structural reconstruction also need a New York general contractor registration. For the extraction-and-drying phase, the industry standard to ask about is IICRC certification.
Is IICRC certification the same as a state license?
NoThey answer different questions. IICRC S520 is the recognized technical standard referenced by New York Department of State guidance.
NY Article 32 mandates that assessors and contractors follow EPA and AIHA guidelines — both of which reference IICRC protocols. The strong hire holds both: the state credential you can verify in the registry, and IICRC-certified technicians on your specific job.
