In an April 2025 Google review, a homeowner wrote that radon in their split level was running at nearly 3.0 and is now less than.5 after Air & Water Environmental's work. That reviewer said Jeff came to them recommended by their realtor. Air & Water Environmental is a Granby, CT company that calls itself a local radon expert and offers radon mitigation systems, radon remediation and radon abatement, along with free estimates; its BBB profile describes radon testing, radon mitigation and water filtration. In a January 2023 Google review, a customer who had used Jeff twice wrote that they were reading high radon in their basement and that 24 hours after the radon ASD installation the results were extremely low. A July 2023 Google reviewer described Jeff helping them with a complicated air and water mitigation issue on a house they were under contract to purchase, before they had even hired him: he discussed the air and water test results, designed a system to mitigate the issues and worked with the sellers to fix the problem prior to closing. The same reviewer said Jeff's installation crew left the installed systems unobtrusive and that his quote was reasonable, with no hidden fees or upcharges. Google shows 5 stars from 5 ratings, and the company is BBB accredited with an A+ grade.
Jeff came to us recommended by our realtor ( whose other recommendations have been solid gold ), and man, did they do a hell of a job. Radon in my split level was running at nearly 3.0 and now less than .5! Plan to use them to install our Aquasana
Jeff from Air & Water is the best at what he does! Before we even hired him, he helped us navigate a complicated air and water mitigation issue with a house we were under contract to purchase. Jeff discussed the air and water test results with us and designed a system to mitigate the issues. He expertly worked with the sellers to fix the problem prior to closing. Jeff's installation crew did impeccable work. We were impressed with the high quality workmanship and unobtrusive nature of the installed systems. Jeff has many years of experience and is an expert in his filed. He is responsive and quick to communicate throughout the process. To top it off, his quote on our system was very reasonable, with no hidden or surprise fees or upcharges. We would definitely work with him again in the future!
Jeff is very professional and responsive. I used him twice and I have only good words to say. I was reading high radon in my basement and 24 hours after the Radon ASD installation the results are extremely low. If you are having issues with one of the following call Jeff, you won't regret it: - Radon Mitigation, Air & Water, - Water Treatment, Filtration, Sanitation, - Mold Remediation (non-toxic), - Odor Control & Elimination (non-toxic).
