When to act

TDEC follows EPA's guidance: take immediate action above 4 pCi/L, and consider action between 2 and 4 pCi/L, since no level is considered safe.1

Finding a certified mitigator

TDEC points Tennessee homeowners to two national directories: the National Radon Proficiency Program (NRPP) professional search and the National Radon Safety Board (NRSB) directory.1

  1. Search both directories by your ZIP code.1
  2. Pick a mitigation credential, not a measurement-only one.
  3. Get more than one estimate and compare what each system includes.2
  4. Confirm the certification is current in the directory before you sign.

How radon gets into Nashville homes

Metro Health says radon comes from uranium decaying in the soil and enters through cracks in floors and walls, gaps in suspended floors and around pipes, cavities inside walls, and construction joints.3 TDEC adds that a house can act like a vacuum, pulling radon in through foundation cracks, and that radon in well water can be released indoors when you shower.4

After installation

Retest between 24 hours and 30 days after the fan starts, ideally with an independent tester, then at least every two years, per National Radon Program Services.5 A free state kit works for the retest if your household hasn't used one yet.6

Areas we serve

We match homeowners across the Nashville area, including these communities and ZIP codes:

ZIP codes are 2020 Census ZIP Code Tabulation Areas, which closely approximate USPS ZIP codes. We list ZIPs that make up a substantial share of each community, so edge ZIPs that barely touch a town are left out, and some ZIPs span two towns.7 Not on the list? Send the form anyway, and we'll tell you if we can help.
