"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 were amazing. I was representing the buyer of a home that came back with a more than normal radon level. They helped educate my buyer and we came up with a plan to move forward with the purchase of the home. A brand new radon mitigation system was installed and radon level came back at less than. 1. Would absolutely recommend them in the future."

"Frontier Foundation and Crawl Space Repair is a top notch company! Their work is timely and second-to-none. Mark inspected and serviced our crawl space dehumidifier along with our radon mitigation system. He is a true professional who went above-and-beyond, and I will definitely request him on future inspections. I feel confident in the quality work Frontier provides and strongly recommend them to anyone in need of crawl space/basement/foundation work! Thanks again, Mark!"

"Radon 1 did a great job. We wanted to have our existing radon mitigation system removed as it was right by our new screened in porch and have a new one installed in different location in our home. The crew removed the old system and installed the new system in an area far from our screened in porch. The installation was done in an expert manner, the crew were respectful of our property, quiet, clean, wore masks and cleaned up after themselves so you would never know they'd been there, all in less than a day. The pricing was competitive, we feel like we got a fair price. I would hire Radon 1 again."

"I cannot speak highly enough of David and his team. When I got a moderately high radon reading on the home I was selling, I had to take care of it quickly so that my closing could go through. David worked me into his schedule and came to my home the day I called. He was delightful, did a thorough inspection, and gave me an estimate. I subsequently got an estimate from another vender, and it was $1,000 more! Not only that, but David had figured out a way to perform the remediation without installing unsightly pipes either on the inside or outside of the house. This involved him working in a very shallow attic space to run the pipes up through the heating ducts, but he was happy to go the extra mile. On the day of the work, David and his wonderful assistant Ryan arrived on time, and spent the better part of a day installing the system. They were convivial and professional without being the least bit instrusive  - I enjoyed the experience! After the installation, David explained it to me in detail, and left a radon kit so that my buyers could check the new levels. Not suprisingly, my buyers are more than happy with the results. If you need to have this job done, call David. You won't regret it!

Radon Detection and Reduction questions, answered by experts

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.
