Radon testing & mitigation in Texas

This site imports no Texas state roster, so these are current NRPP and NRSB certifications from those programs’ public finders. A national certification is not a state license. We group people by the city on that file. We do not invent neighborhoods. Source: NRPP.

Questions about radon credentials in Texas

Does Texas license radon testers and mitigators?

We have not confirmed whether Texas requires a state radon credential. That means unknown, not that none is required. We do not guess at state law, so this site publishes no answer it has not checked. Ask the Texas radon program.

How do I verify a radon credential in Texas?

The 72 listings shown here are current NRPP or NRSB certifications, verifiable on those programs' public finders. The latest record check was September 14, 2026; check each listing for its own date. If Texas also requires a state credential, ask the provider for it and check it with the state agency.

Is an NRPP or NRSB certification enough in Texas?

We cannot say for Texas, because we have not confirmed whether the state requires its own credential. A national certification is never a state license anywhere. Treat NRPP or NRSB as evidence of training, then ask the state radon program what else is required.
