Professionals
Who tests and fixes radon in Tennessee, what Tennessee's own program says about licensing, and how to check a credential before you hire.
Updated October 2, 2026
Short answer
No business that Tennessee itself licenses or certifies is listed on Radon411 yet. Ask Tennessee Radon Program what it requires before you hire.
1 business with an address in Tennessee appears in a separate list because another state's registry lists it. That does not mean Tennessee licenses it.
The rule
Tennessee'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.
Tennessee 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 Tennessee; Tennessee's radon program is the place to ask who works there.

Before you hire
Hiring
Ask for the credential and ID card, how the test will be guarded against interference, and when the report will come. EPA recommends an independent, qualified tester for the test after a system is installed.
Get more than one estimate, contact references, and ask for a written proposal and a contract before any work starts.
