How to verify a mold assessor's license in your state

Many companies call themselves "certified" mold inspectors. Only a few states actually license mold assessors, and where they do, you can check the license yourself in about two minutes. Here is how, state by state.

The three checks, in any state that licenses mold work

1. Get the license number. Ask for it before you book. A licensed assessor can give it to you right away.
2. Look it up with the state, not the company. Use the agency's own search (links below) rather than a screenshot or a badge on a website.
3. Match the record. Confirm the name (person or business) matches who you are hiring, the license type is for mold assessment (not only remediation), the status is active or current, and the expiration date has not passed.

Florida

Florida licenses mold assessors and mold remediators through the Department of Business & Professional Regulation (DBPR), under the Mold-Related Services Law (Ch. 468, Part XVI, Florida Statutes). Assessor licenses start with MRSA; remediator licenses start with MRSR.

• Look up a license at the DBPR public license search (myfloridalicense.com) by name or license number.
• Or browse Florida's licensed mold assessors by city, built from the DBPR registry.

Texas

Texas licenses mold assessment and remediation through the Texas Department of Licensing and Regulation (TDLR). License types include Mold Assessment Consultant, Mold Assessment Technician, Mold Assessment Company, Mold Remediation Contractor, and Mold Remediation Company.

• Look up a license in TDLR's public license search.
• Or browse Texas mold assessment consultants by county, built from TDLR's public CSV.

New York

New York licenses mold assessment, remediation, and abatement under Article 32 of the Labor Law, administered by the Department of Labor (DOL). Businesses hold a Mold Assessment Contractor license (SH125) or Mold Remediation Contractor license (SH126); individuals hold a Mold Assessor license (SH128). License numbers end in -SHMO. The state also prohibits the same individual from performing both the assessment and the remediation on the same property.

• Check a business in the NYS DOL contractor-license dataset on data.ny.gov (updated daily).
• Check an individual assessor in the NYS DOL individual-license dataset.
• Or browse New York mold assessment contractors by city.

Louisiana

Louisiana licenses mold remediation contractors through the Louisiana State Licensing Board for Contractors (LSLBC). It does not issue a separate state license for mold assessors.

• Look up a remediation contractor in the LSLBC public search.
• Or browse Louisiana mold remediation contractors by parish.

Washington, DC

The District licenses mold assessors and mold remediators through the Department of Energy & Environment (DOEE).

• Check the DOEE list of licensed mold professionals.

Every other state

Most states do not issue a state mold-assessor license. In those states there is no state license to check, so:

• Ask which private certification the inspector holds, and verify it with the certifying organization.
• Ask whether they hold any state contractor or home-inspector license that applies to their work, and check that with your state.
• Ask for proof of liability insurance.
• Be cautious of a company that offers to both test for mold and remove it — New York, for example, prohibits the same individual from doing both on one property.

Frequently asked questions

How do I check if a mold inspector is licensed?

Ask for their state license number, then look it up yourself on the issuing state's public license search: Florida DBPR (myfloridalicense.com), Texas TDLR, New York DOL (data.ny.gov), the Louisiana State Licensing Board for Contractors (remediation), or DC DOEE. Confirm the name matches, the status is active or current, and the expiration date has not passed.

Is a mold certification the same as a state license?

No. A certification comes from a private training or trade organization. A license is issued by a state agency, which can deny, suspend, or revoke it. In states that license mold assessment, a certification alone does not authorize someone to do the work for pay.

Which states license mold assessors?

Florida, Texas, and New York license mold assessors and publish their registries, and Washington, DC licenses mold assessors and remediators. Louisiana licenses mold remediation contractors but not assessors. Most other states do not issue a state mold license.

What if my state does not license mold inspectors?

Then no state license exists to check. Ask which private certification the inspector holds and verify it with the certifying body, ask whether they hold any state contractor or home-inspector license that applies to their work, and ask for proof of insurance.
