"Ryan was the most informed and knowledgeable of the 5 companies I had estimates from. His equipment was the highest rated on consumer reports, and his workmanship and attention to detail was absolutely excellent. He went above and beyond to install the radon mitigation system so its hardly noticeable and didn't detract from the home's curb appeal. All other companies wanted to put a chimney of pipe outside along the house exterior and didn't offer to test the slab substrate underneath to determine suction ability prior to installation which insured excellent removal power. He also sealed all cracks in the basement. Everything completed in timely and professional manner and he left the site spotless on completion. As a long time Home Adviser user I highly recommend his services."

"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!"

"Went well. Since I was not clear on what they had done during their initial visit, they came back and answered all of my questions to my satisfaction. They were determined to make things right."

"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."

"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.

"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."

"Excellent advice and communication from Alex. He was exceptionally professional and very knowledgeable about Radon."
