Mold & Water Damage Restoration in Larchmont & Mamaroneck, NY
Larchmont and Mamaroneck are old and flood-conscious: the typical Larchmont home was built around 1940 (90% before 1980) and the typical Mamaroneck village home around 1953. Mamaroneck publishes its own flood-preparedness handbook. New York's mold law generally requires a licensed mold assessor to write the plan and clear the job, and a separate licensed remediation contractor to do the work, so the same company should not be both on one project. You can check license status in the NYS Department of Labor's open dataset. Listings here that carry a mold license note the number and expiry we saw, but always re-check before hiring. Mold work in a Westchester home can also require the county home improvement license.

What it costs
We did not find a published Westchester-specific mold price list, so these are national HomeGuide ranges: $1,500 to $6,000 for a partial basement, $6,000 to $15,000 for a full basement, and $500 to $1,500 for a small area of 10 to 100 square feet. A mold inspection is $300 to $650 for an average home. In New York, a separate licensed assessor and licensed remediator are generally required on larger jobs, which can affect total cost.
