"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

"Dennis is very knowledgeable. He walked me through the whole process when he came to workup an estimate. He answered all my questions. Due to an addition, it was determined that I needed an 2nd suction point thus a more expensive install (but still reasonable). That is something that I wouldn't have been aware of if I had gone with the telephone estimate that I got from another vendor. It would have been an unpleasant surprise if the other vendor came for an install and then increased the price. Every home is different so I was happy that Dennis had come out to do an estimate. I was able to prepare for the install by clearing the area where the work would be done. It allowed for an orderly move of boxes versus paying them to move the boxes or they waiting around until the area was cleared. I was very happy with the actual installation. There was no mess that I had to clean up. The set-up was very neat and professional. The system began to work immediately. The radon levels are now in the acceptable range. I would highly recommend Boston Radon."

"Mohan was just phenomenal. We called him on a Friday to see if he could do a home inspection for a house we plan to buy. I had difficulty scheduling a time when he and my buyers agent were both free, so Mohan called my agent himself to work out the schedule. Within 5 minutes of calling Mohan, I had an inspection scheduled for the next day. The appointment was for 1pm and he said it would take about 1.5 hours. We arrived a few minutes before 1pm and Mohan had already arrived and inspected the roof — he came early because it was going to rain and he wanted to still safely inspect the roof. During COVID19, Mohan was very clear ahead of time how we were all going to maintain safety. He wore a mask the entire time and had a laser pointer to show us stuff from a safe distance. He took pictures of everything. He explained everything and was so patient with us, especially as first time home buyers. Mohan also isn’t alarmist but still very upfront about potential repairs. For example, Mohan would say that we should replace the hot water heater because of leaking and explained how much it would cost. He also would show us stuff that didn’t need to be fixed now but should be fixed within the next X amount of years. He even showed us preventive stuff - for example, the gutter downspouts were draining right next to the home, which has a stone foundation and can be highly susceptible to water damage. Mohan suggested to buy a dehumidifier and place it in the basement to prevent moisture and prevent damage that hadnt even occurred. The appointment was for 1pm Saturday and by end of the day, I had received a written report of his inspection."
