"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!"

"Cole came out and trouble shot why my present radon system was not working. The first installer had drilled through my footing instead of my slab. He did not glue the joints and used poor quality materials and craftsmanship. Cole ripped out all the old system and installed quality materials and did a fantastic job making it look good. On all three levels of my house the radon is below 1. I would recommend Top Shelf Radon and use them again on any new house I purchase."

"Had to proactively remind them for a testing kit but otherwise swift and timely service. Radon level was reduced."

"Mr. Coffee is a hero who risks his health daily to help mitigate dangerous radon problems for strangers who call for help. This is a dangerous job with daily high radon exposure and when I asked, he said he is aware of the risks but gets his health scanned multiple times a year. I called Covenant Air back in December after noticing that my Safety Siren Pro radon detector kept reaching alarm. Mr. Coffee came out and assessed that I could probably fix the problem myself by sealing some obvious cracks, especially around some pipes, and recommended the products so that I can do it cheap DIY. He was obviously not pushy to scare people into signing contracts, but actually tried to dissuade me from hiring him right off on installing sub slab depressurization. Although the DYI route he recommended would've been cheaper, I hired him to performs the job. The sealing did bring the radon level down where my detector's alarm didn't go off, but I wanted to lower it as much as possible. He then recommended a passive ventilation route given my reading. The passive ventilation again slashed the radon level in half, but I wanted the radon level down even further, so I ultimately opted to install the fan after weeks of data collection and analysis. He installed the fan so that I could easily turn it off to save energy based on seasonal variations. He is a very personable and methodical person, and prefers to monitor the progress of his work so that his customers don't hastily incur unnecessary cost. You almost never see someone like that in the service industry, and I cannot recommend him highly enough.

"Installation went smoothly - they arrived on time, took as long (~half a day) as estimated, and did a great job both technically and aesthetically (aside from the PVC pipe on the side of the house, which isn't really their fault). Our radon levels in the basement dropped from well above the recommended limit to basically background numbers. I give them a 'B' on price because their estimate was 50% more than the second estimate we got. We asked, and they matched the lower number without complaint.
