"Just everything about Tennessee Radon Services impressed me. The quick communication right from the start was convenient. The next day estimate appointment was a surprise and then two days later it was done. And the mitigation system we got is totally top of the line. Whisper quiet and high gauge pvc. And for the bottom of the estimate range too. Stop searching for your Radon mitigation service. These guys are the real deal."

"The Radon Guys saved the day and the sale of my house! The existing mitigation system (from another company) was installed incorrectly which was discovered during a home inspection and testing. From re-testing, to diagnostics, to repairs and post testing, the Radon Guys were a pleasure to work with. Devin , Nick, and Chris are knowledgeable, professional, and understood the urgency with a very tight deadline to close. The repairs were completed with minimal disruption or cosmetic surface damage and I was kept informed of every step. The area was cleaned after the work was completed. As we had already vacated the home, I was immediately notified of the passing score and the report was received shortly after. The closing was able to proceed without delays. If you need radon testing or mitigation, save yourself the headaches and just use The Radon Guys. You won't be sorry!"

"Overall, we were very satisfied with the knowledge and quality of work that Covenant LLC provided. We had Covenant LLC install a radon mitigation system for our basement. Initially my husband and I met with David for the estimate and consultation. David spent the time to explain how radon can get into the basement, what the system would look like, and how he was going to make sure it was working. After meeting with David at Covenant, we met with a competitor who were definitely not as knowledgeable, were not going to seal any of the cracks or holes in the foundation or even follow industry standard by venting through the roof of the house. The day of install the crew was personable and professional and if they had any questions, they asked. The 3" pipe that Covenant had to install to run through a closet and into the attic. In order to do this, they had to drill through the porcelain title floors and run through 3 shelves. They spent extra time to jig-saw cut the shelves around the pipes and they took special care not to crack any of the porcelain tiles and when finished it looked like it was built with the house. After completion, Covenant came back and tested the radon levels which were reduced to below their guarantee, which itself is orders of magnitude below the EPA limit. We were probably not the easiest clients to work with as we had Covenant move the roof penetration several times until the noise was completely unnoticeable. David was always polite and professional and he wouldn't be satisfied with the job until we were satisfied. We highly recommend Covenant Air to anyone who is considering these services."

Radon Detection and Reduction FAQs, answered by experts

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

Yes, many systems include warranties for performance. Confirm terms with your installer.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.
