"Radon Consultants gave a very competitive bid for the work, so we hired them. The work was done as promised, when promised, and with excellent results. They took an incremental approach, which would have saved money. Our problem was about 70% solved by that approach. By adding additional capability to our radon mitigation sysrem, the remainder of the ptoblem was taken care of at a very reasonable price. Their total price was about the same as a competitorâ s price for the first phase."

"Alan was excellent. He explained everything about Radon and the Radon system we needed. He took the time to map out the best place to install our Radon system. We really appreciated his knowledge of Radon and the radon system. Alan will be our permanent Radon person. I highly recommend Alan and his company, you will not be disappointed !!!!!!!"

"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!"

"Ed was very professional and courteous and gave great input and evaluation of the property."

"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."

"Radon One replaced our crawl space vapor barrier with a super high quality vapor barrier that should last for a very long time. The guys working on the job were polite, professional, and even installed a better product than we had ordered due to lack of supply, at no extra charge! We believe Radon One was very knowledgeable about our different options and steered us graciously toward the decision that was the best value for us, instead of trying to upsell services we did not need. Thank you!!"

"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."

"David is very trustworthy, ethical, extremely thorough and you can trust that he will give you all the right information in the correct balance to make the right decision for you!"

"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."

"This review is for Master Services, Crawl Space and Foundation Repair in Knoxville, TN. phone # 8653453030 , [*** Link removed ***] . We had the pleasure of meeting Nick (Sales Inspector) and Brandon, Brandon, and Jacob (Installers). We hired Master Services on 2/16/21 (work done on 2/22/21) to install a WaterGuard sub-floor drainage system in our home in Greeneville, TN. Nick is a terrific salesman. He is professional and does not push any unnecessary work. Brandon, Brandon and Jacob (I believe Jacob was our installers name - sorry if not), did such a tremendous job. They worked quickly, efficiently, and made sure to keep our home free of mess. Overall we are very happy we hired Master Services and recommend them to anyone needing foundation repair."
