Is it licensed here?

Does New York license mold remediation?

Yes. New York requires mold remediation companies to hold a license from the Department of Labor (DOL), and the DOL keeps a public lookup where you can confirm a license is active before you hire. A listing here shows a license only when we have one on file for it. License records come from the state's official records, and we check expiration dates every day.

A license tells you the company cleared the state's requirements to do this work. It does not tell you how good the work is, so the credential check is where the vetting starts, not where it ends. Insurance, a written scope, and, where the job calls for one, an independent check of the result still matter, and they are the things a credential cannot show you.

Strict Licensing State

New York law requires mold remediators to hold a valid license from Department of Labor (DOL). Doing mold work without a required license breaks state law, so check the license before you hire. License records come from the state's official records, and we check expiration dates every day.

What to ask a mold company for in New York

  • The license number, confirmed on the DOL lookup before you sign
  • A certificate of insurance showing general liability, confirmed with the carrier
  • A written scope: containment, what gets cleaned or removed, and who will fix the moisture source
  • How the finished work will be checked and documented, with an independent check where the job calls for one
  • Recent reviews under the same business name and address that appear on the quote

What a typical job costs

What mold remediation costs in New York

$1,223 – $3,757typical job, nationwide

Source: HomeAdvisor, 7,952 reported project costs, June 2026

We don't have a figure specific to New York. This is the national range. A single contained problem, like one wall or a bathroom ceiling, often comes in under it; whole-basement or post-flood work runs over it. If you get an independent assessment before the work, which we recommend, it is priced separately from the remediation, and so is an independent check after it where the job calls for one. Both should be.

Size it to your own job

Two questions give the range for a job like yours, and where each number comes from.

How much
A small patch, one area or room, several areas, or throughout the home
Where
On a surface I can see, inside walls or under floors, or in the AC or ducts
Then
Your ZIP finds verified pros near you

What comes back: the remediation range with its source, the assessor's visit and a clearance test, which not every job needs, as their own lines, and a total.

Questions people ask

Common questions about mold remediation in New York

Answered without a sales pitch.

  • How much does mold remediation cost in New York?
    Nationally, a typical mold remediation job runs $1,223 to $3,757, from 7,952 project costs reported to HomeAdvisor. We don't have a figure specific to New York. The price moves with how much material has to come out, whether the moisture source is fixed in the same job, and whether containment and air filtration are needed. Get the scope in writing and ask how the finished work will be checked. If an independent check after the work is planned, ask what it will cost, because it is priced separately from the remediation.
  • Does New York require a license to do mold remediation?
    Yes. New York requires a license from the Department of Labor (DOL) for mold remediation work, and the DOL runs a public lookup where you can confirm a license is active. Ask for the number before you sign and check it yourself; a license is a real credential, but a lapsed one is easy to miss.
  • Can you sell a house with mold in New York?
    Selling is legal. What gets sellers in trouble is hiding a problem they knew about: in most states a known mold or water problem is a material defect that has to be disclosed, and a buyer's inspector tends to find it anyway. The two clean routes are to remediate before listing and keep the records that document the finished work, including any verification report, or to disclose it and price the work in.
  • How do I check a mold company in New York?
    Start with the license number on the DOL lookup. Then ask for a certificate of insurance you confirm with the carrier and a written scope of work, and look the business up under the exact name and address on the quote. Our listings show which of those checks we could complete for each company.
  • Is a free mold inspection a red flag?
    Not on its own, but know what it is. A remediator inspecting your home before it quotes is normal, and a free visit is a fair way to get an estimate. It is not an independent assessment, though: a company that also sells remediation has a potential financial stake in what it finds. Our recommendation is to pay for an assessment from a company that will not do the remediation, which takes that incentive out of the diagnosis, and to have an independent check of the finished work where the job calls for one. That holds with or without a state license behind it.
  • What can renters in New York do about mold?
    Report the moisture problem to the landlord in writing, with photos and dates, and ask for the leak or ventilation fault to be fixed rather than the stain painted over. If nothing happens, the local building or code enforcement office can inspect for the underlying water problem even where there is no mold rule to enforce. Keep every message; a tenant remedy or a health complaint will rest on that record.
