Radon Mitigation Pros in Memphis, TN

Writing the Memphis radon mitigation city page now.

Finding a qualified radon mitigation contractor in Memphis shouldn’t feel like navigating a swap meet — but between unlicensed handymen advertising “radon services” on Facebook Marketplace and national chains that quote you over the phone without ever checking your home’s foundation type, it often does. Memphis sits in a patchwork of EPA radon zones, and Shelby County’s mix of slab-on-grade ranch homes and older pier-and-beam construction means there’s no one-size-fits-all fix. This directory exists to cut through the noise and connect you with credentialed professionals who actually know what they’re doing here.

How to Choose a Radon Mitigation Contractor in Memphis

• Verify NRPP or NRSB certification — specifically for mitigation, not just measurement. These are separate credentials. A contractor certified only for measurement testing cannot legally install a mitigation system under Tennessee’s radon program guidelines. Ask for their certificate number and verify it at nrpp.info.
• Ask about your specific foundation type. Memphis has significant housing stock with crawl spaces, block foundations, and slab-on-grade — each requires a different mitigation approach. A sub-membrane depressurization system in a crawl space is a different job than sub-slab depressurization. If a contractor gives you a flat quote without asking, that’s a red flag.
• Get pre- and post-mitigation testing in writing. Any legitimate contractor will document your starting pCi/L level and return to retest after installation. If the post-install number doesn’t drop below 4.0 pCi/L, the system needs adjustment — and that should be covered under warranty.
• Check for permits. Shelby County requires a permit for new radon mitigation system installations. Contractors who skip this step aren’t just cutting corners — they’re leaving you with an unpermitted modification that can complicate a future home sale.
• Ask about the fan warranty and labor warranty separately. Most quality fans (RadonAway, Fantech) carry 5-year manufacturer warranties. A contractor who only offers 1-year labor coverage on a system rated to run 24/7 for a decade doesn’t stand behind their work.

Pro Tip: Memphis real estate transactions move fast, and radon testing is often requested during the inspection window. Find a contractor who can turn around a test report in 48 hours — many certified pros offer short-term electronic testing specifically for closings.

What to Expect

A radon mitigation system installation in Memphis typically runs $800–$1,500 for a standard single-point sub-slab or sub-membrane system, with testing-only services ranging $150–$400 depending on whether you use short-term or long-term devices and whether you hire a professional or just buy a mail-in kit. Most installations take 3–5 hours, and you’ll get a retest 24–48 hours after the system has been running.

Reality Check: The cheapest quote is rarely the right quote. Radon mitigation is one of those jobs where a $200 discount up front can mean a system that never gets your levels below 4 pCi/L — at which point you’re paying for a second contractor to come fix the first one’s work. Focus on certification, warranty terms, and whether the post-mitigation retest is included in the price.

Local Market Overview

Tennessee doesn’t mandate statewide radon testing at home sales the way some states do, which means awareness in Memphis lags behind markets like Nashville or Knoxville — but that doesn’t mean the risk is lower. The Tennessee Department of Environment & Conservation (TDEC) maps parts of Shelby and Fayette counties in EPA Zone 2 (moderate potential), while some neighborhoods in the eastern suburbs near Germantown and Collierville have returned Zone 1-level readings in residential surveys. If your home was built before 2009 without radon-resistant new construction (RRNC) features, it’s worth testing regardless of what the zip-code map says.
