"Avert Radon LLC , specifically Chance, recently completed radon mitigation work at my residence, installing two systems. I typically refrain from writing reviews, but felt compelled to share my experience with Avert Radon LLC . I'm extremely satisfied with the results, as the radon levels are now virtually undetectable. Chance demonstrated exceptional professionalism throughout the process. The communication was excellent, and their meticulous attention to detail was also outstanding. Furthermore, their post-installation follow-up has been consistently excellent. I highly recommend this company without reservation. They are among the best service providers I've encountered. if I could give it more than five stars, I certainly would!"

"I have hired three Radon companies over two houses. Radon One is without a doubt the best company. They have an excellent warranty and back it up without reservation. Our current house is a Radon problem-it had very high readings when we bought it. Radon One has worked with me to get the readings to safe levels including several return visits. I highly recommend them."

"David is a true professional in the radon field. He provided me with information on how radon flows on my property that I could not learn elsewhere. He found a gap in the slab that I was unaware of and recommended that I fill it and recheck my radon level again prior to hiring him. Few people provide that kind service. I will hire him if I have high readings later because he is honest and has the experience."

"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."

"I am a homebuyer. I contacted the Inspector (Pat) through Angies list asking if he could provide me several days and times he would be available for doing a home inspection, and also for pricing. He was prompt in replying, provided both pieces of information requested, and also noted that he could do Radon inspections at a good price. His response to me was very professional and made a good impression on me."

"Project went very well. Horace and Vic showed up on schedule, explained clearly what they would be doing, kept me apprised of the progress as the job was performed, and walked me through the results. I was a bit surprised by the price for the work, but this was the only company that responded and committed to do the work, so I really don't have a good comparison price point. Note that the process was NOT mudjacking, but jacking and reinforcement with a poly product that offers many benefits over mudjacking."
