"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."

"Danny Wine from A2Z Inspection provided excellent customer service. He was professional, and always quick to reply. I asked a lot of questions and he was patient and thorough regarding the process. I was in a rush to book my home inspection and he was accommodating. You never know these days when finding service online but A2Z proved to be trustworthy and professional. I would highly recommend using them. Five stars for sure!"

"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 Detection and Reduction FAQs, answered by experts

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
