"Set up an appointment for an initial 10 minute phone call to talk about what we wanted. Tom ended up spending 25 minutes with us and answered a ton of questions. We subsequently set up an appointment for an initial pre-build inspection of the foundation, framing, roof, and windows. Tom was very thorough. He obviously knew his stuff. Pointed out several items that needed addressing before the insulation and walls went up. Couldn’t be happier with the amount of time he spent, how thorough he was and how much he listened to all my stupid questions and answered them in a language that I could understand. We will have him back before the next phase starts and probably a couple more times before we close. Anyone building a house or buying a new home would be wise to hire Tom. Great piece of mind and cheap insurance. Plus, he’s a really nice guy to boot."

When there is an issue, we talk about what the issue is and what needs to be done to fix it. After the inspection we write a detailed report that is specific to your property and that serves as an operating manual for your home. We answer follow up questions for as long as you own the home.

We are a company that installs Radon Mitgation systems. and always guarantees the result. We are a Massachusetts based company and always aim to please are customers.
"It is really a nice experience to work with John and Kevin. Our house has a funny foundation. There is a block in the middle and half of the house has radon and the other half does not have much. At first time, Kevin came on time, worked very professionally and got the first pipe and big fan installed. But unfortunately, this pipe is in the not much radon side and the radon score did not drop down too much. We were very worried and called the EAGLE ENVIRONMENTAL again. They arranged the second appointment and Kevin did more tests and installed the second pipe on the side of the foundation WITH NO EXTRA COSTS. And then magic happened, our radon number dropped to almost 0 now. :) Thanks you Kevin and EAGLE ENVIRONMENTAL again for the fantastic work!"
