The windows look fantastic, and the process was smoother than I ever could have expected. Highly recommend and will absolutely use them again for future insulation needs!

Christine was particularly helpful and professional in walking us through and getting us connected with MassSave - she made the process very easy and was a pleasure to work with. The crew who worked on our house was wonderful - they consulted with us about everything they were doing to keep us informed and up to speed on the process and the updates that needed to be made to the plan (it's a 130 year old home, that had some unexpected nooks and crannies - but they handled all the changes and updates to the plan with MassSave for us). The crew was also very careful and meticulous about minimizing mess in the house as much as they could and took care to clean up each day. Would highly recommend.

No problem, but then when McEachern came out, the problems began. They didn't seem to know what they were going to insulate in my house, however we worked through it. Once they arrived for the job, the foreman "hadn't even spoken" once to the owners about the job and the foreman seemed confused about what work to perform. I wrote a quick email message to Christine at McEachern and she became argumentative (this wasn't the first time). Basically, they did a HORRIBLE job smearing silicone over painted cedar shingles, left a huge mess for me to clean off and then took off. Before they even came, they wanted me to put a box vent on a small portion of my roof (the main roof has a ridge vent). So, I was forced to hire a roofer to put a ridge vent in, which cost me $1,000. Run. Run away from McEachern, even though they've been doing this for years.

The first day the foreman did not get the correct work order and only inistalled the permiter seal without removing all insulation (and was rude when I asked why the removal did not take place). The work was the lowest quality I have ever experienced and took 3 - yes 3 - return trips (after my complaints) to finish the job to a reasonable standard. When they did remove the old insulation, they left pices over the floor and one section in the ceiling- no execuse for this. I recommend using a diff vendor as this group was equal parts rude and incompetent.

We recently had 3 other insulating companies evaluate the situation. All three said that the job was poorly done and the insulation was not properly installed.

The second time was for spray foam beneath a flat roof. Both jobs were done professionally and fully satisfied the requirements. They left our house clean and neat. The price on the MassSave insulation was wonderful because it was subsisized by MassSave! We paid for the spray foam insulation ourselves and found Metro Insulation's price to be fair and competitive. I find that the recomendations that I trust are those where the customer has used the company more than one time. We are two time users and very happy customers. I recommend Metro Insulation very highly.

I had 12 windows installed by American Building Technologies, and this was one of the worst…read morecontractor experiences I have had. The installation crew itself was excellent--hardworking, polite, and professional. My issues were with management, particularly Jose. We agreed on a specific brand and style of windows, including three large living-room windows. When the order arrived, I was told they could no longer do the three large windows, but the price was not reduced. I was told the remaining windows would be installed and the large ones reordered. When the windows came off the truck, I immediately noticed they were not the brand we had agreed to. I contacted Jose and found him dismissive and disrespectful. Because my old windows had already been removed, I was told these windows would be installed and the correct ones ordered later. An inspector was then sent as though the job was complete. Every installed window failed inspection because the required safety glass was not used. The proposed solution was to replace only three windows and apply safety film to others to meet code. I am now left with windows that were not what I agreed to purchase, that failed inspection, and an unresolved dispute over the correct windows and pricing. Based on my experience, I would not recommend American Building Technologies. I am also very disappointed that Mass Save refers homeowners to this company.

I have been building super insulated homes since the mid-70s. 10 inch offset stud walls with 18+" Fiberglas insulation in ceilings with six mill poly vapor barrier all seems taped. Fiberglass cannot compete with foam in the slightest. We were one of the first builders to use rigid foam insulation below ground. They came out and did a stellar job on my own home and greatly reduced my heating bills. I replaced the aging insulation in my attic that was 18 inches thick with an envelope-based foam system in the rafters. They did a really nice job thermally bridging all of the rafters. This greatly increased the amount of usable space and will have a large impact on our AC bill and the longevity of our roof as well. They were very careful with everything. They made sure all the foam had a great contact to sill plates and other very critical areas for air leakage. They did a great job on all the hard and tight areas. Extremely professional and courteous, all overspray areas were carefully sealed and taped off. The crawlspace into a cathedral ceiling was extremely tight. They did a fantastic job getting up there and sealing it extremely well. My HVAC guy said he had never seen a home foamed so well. I could feel the difference in the home immediately. Highly recommended. I would honestly not use anyone else. Especially because any questionable area has always been carefully taken care of without any problems. Sol personally inspects each job before and after. And he's a nice guy. :-)

We invited Mass Save back recently (for windows), and the inspector said he'd never before recommended "no insulation upgrades" for an old house, but he did for ours since Rob's 15-year old upgrades were so impeccable! Moreover, the inspector actually asked to photograph the tricky basement area to use as exemplar of an ideal installation.
