"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

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.

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

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.
