A. Douglas Thibodeau L.L.C.

I initially called Mike the owner at the end of 2024 and he explained why, at my levels of 1.6 pCi/L, it wasn’t really necessary or cost effective to remediate. He immediately built trust and didn’t hard sell. Fast forward after basement remodeling and my numbers were at 2.3 pCi/L and rising, often with spikes approaching 10. I gave Mike another call and he asked for photos and videos of the space. Within a day he explained how he’d approach the split basement/crawlspace of my home with two suction points and sent me an estimate. Two weeks later I called him up to get added to his schedule. Mike and his son were professional, communicative, and knowledgeable. I was able to talk with him about placement and fan types. He even showed me the soil he pulled from under my slab when performing

Mike and his son installed our radon mitigation system. They were extremely courteous and friendly. They made sure to put down a drop cloth from our front door to our basement door in order to protect our ugly carpet! We are still impressed with how clean and neat the whole system looks. We've had great results. Before the electrician came out to finish the job we noticed the system wasn't working so I called Mike. He picked up the phone right away and helped me troubleshoot. Eventually we found that it was because one of our outlets needed to be reset. I appreciated that he was prompt to answer and talk me through the whole thing. Since the electrician finished his part, we don't have to worry about that being an issue anymore. OH! And they are less expensive than others I got quotes fr

Our radon levels weren't terribly high (~3 pCi/L), but we wanted to make the basement as safe as possible for everyone in the house. Because the levels were already fairly low, we didn't have unrealistic expectations for the results. But we were pretty shocked when the post-install test came back with a level of 0.5 pCi/L. The team was very helpful and professional throughout the process. The installation was great and we're really happy with the results.

Mike installed our radon mitigation due to a high level of radon in our water. He was extremely professional, thorough and super knowledgeable. He took the time to answer all of our questions and didn’t rush at all. You can tell he cares about providing quality work. Would highly recommend!

From my first contact with the owner, Mike, I knew I made the right decision. There are many options for radon abatement, but I wanted a company that would provide a custom installation tailored to my specific concerns. Mike and his crew did just that. They went above and beyond to ensure the system was hidden away in my finished basement and installed in a neat and professional manner on the exterior. He was on time, stayed in constant communication, and made sure the system was functioning properly. Best of all, his pricing was extremely reasonable! I don’t often take the time to write reviews, but I truly believe that A. Douglas Thibodeau is the best option for radon abatement in the area.
