"It was difficult to work with them, he didn't respond quickly, things kept coming up, but he did finally do the job and was very professional. He dropped our Radon level from 8 to 1.2"

"The service was good. He showed up on time and did the test. The only problem I had was that he is not a full service, he only checks for asbestos and does not remove.The test took longer than I was told, but I don't think he had a choice. Overall he was ok, just not a perfect match for my needs."

"Chris was very professional on the phone and it surprised me that, for such a low price, I was getting as much as I did! MA CARRES is a FHA 203k qualified inspector (though I only hired him as a home inspector) AND a Realtor so I got a little bit of everything when he and his employee came. The fact that they are retired firefighters was a bonus as I had some questions about darkened wood and they let me know where the CO2 detector should really be located for best effect. I definitely will use MA CARRES in the future!!"

"Mark did great work and made the radon abatement system blend well with the house. The office response time was slower than I would have liked, but the price and quality of work was worth the wait. All of the people I interfaced with were extremely helpful and nice. I would highly recommend this company."
