Radon professionals in South Carolina

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

Updated October 2, 2026

Short answer

Radon professionals in South Carolina, in brief

No business that South Carolina itself licenses or certifies is listed on Radon411 yet. Ask South Carolina Radon Program what it requires before you hire.

7 businesses with an address in South Carolina appear in a separate list because another state's registry lists them. That does not mean South Carolina licenses them.

The rule

Does South Carolina license radon professionals?

South Carolina's radon program page, checked on September 25, 2026, does not say whether the state licenses or certifies radon professionals. Ask the program before you hire.

South Carolina 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 South Carolina; South Carolina's radon program is the place to ask who works there.

Before you hire

How to check a credential in South Carolina

  1. South Carolina's own list

    Start with South Carolina's radon program. Licensing is done by the state, and most states can give you a list of radon service providers working there.

  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.
