"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."

"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 questions, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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.
