Radon professionals in New York

Who tests and fixes radon in New York, what New York's own program says about licensing, and how to check a credential before you hire.

Updated October 2, 2026

Short answer

Radon professionals in New York, in brief

No business that New York itself licenses or certifies is listed on Radon411 yet. New York's radon program says the state does not license or certify radon professionals.

12 businesses with an address in New York appear in a separate list because another state's registry lists them. That does not mean New York licenses them.

The rule

Does New York license radon professionals?

No. New York's radon program page, checked on September 25, 2026, says:

NYS does not certify or license radon testers.
Radon Program, read September 25, 2026

New York is not on the list of states with radon credentialing programs that EPA's state contacts page publishes. Licensing is done by the state, not by the national programs, and EPA requires states that receive radon grants to give the public a list of only those providers credentialed by the state or by NRPP or NRSB.

Radon411 reads no licensing list for New York; New York's radon program is the place to ask who works there.

Before you hire

How to check a credential in New York

  1. New York's rule

    New York's radon program says the state does not license radon professionals, so ask for a national certification instead, and check it in the next two steps.

  2. NRPP's search

    The National Radon Proficiency Program's search finds its Certified Mitigation Specialists and Certified Measurement Professionals by area, by name, or by the 6-digit NRPP ID number a professional can give you.

  3. NRSB's search

    The National Radon Safety Board's search finds a professional in your area, or confirms that a named professional is NRSB certified.

  4. The ID card

    The programs usually issue a photo ID card showing the holder's qualifications and its expiry date. Ask to see it, and if in doubt, check with the body that issued it.
