The NY rule that changes your quote

New York Labor Law Article 32 requires mold assessors and remediators to be different, separately licensed entities. Budget for both: the assessment ($300–$800) produces the remediation plan that contractors then bid on. It feels like an extra step — it is actually the mechanism that keeps the scope honest.

Cost questions

In New York, yes — and you should want it that way. Article 32 separates assessor from remediator so the person selling the work is not the one deciding how much work you need. Assessments typically run $300–$800.

Rarely as a standalone event. It is usually covered only when mold resulted from a covered water loss — which is one more reason to document water damage properly from day one.
