The owner of this insulation business has been doing business for 10 plus years. He was cordial and polite with his responses. Well let me tell you, I am glad I used fast insulation. Him and his team came in early today which was Saturday morning and knocked out the project in 4.5 hours. There workmanship was absolutely awesome and professional. I had them buy the insulation and products to do the job as this is there business and they know what to get and order based on the square footage. They got to my house and from beginning to end they never stopped working. I made them breakfast and brought it to them as they never stopped working and figured they deserved some good energy food to continue the good work ! There price was WAY better then any of the other companies. They took the job and showed up on time and completed the work. My attic was warm and cozy within hours of them leaving. Insulation is the way to go if you don't have it . I am sure my fuel bill will go right down now and my heat will stay in my house and not out . I research and price out anything I have to do to my house. This company truly will do a fantastic job ! I give them 5 stars 100 percent ! Again, all the other companies prices where way higher then any of the others. The bottom line is there work is neat and they come and do a professional job. My wife was extremely happy with the work ! I myself could not be happier ! I took before shots and after shot pictures to show the great work that this company did !

They were able to work around our scheduling constraints, did fantastic and lightning-fast work, and cleaned up after themselves. The cost was very reasonable and they were extremely responsive to our questions and concerns. This is the best experience I've ever had with a contractor, and would not hesitate to recommend them to anyone who wants professional, quality insulation work done.

As other reviews mentioned, Curtis and his crew carefully protected our (brand new) hardwood floors with lots of tarps, threw plastic over furniture and vacuumed after each day of work. Our home feels so much warmer and I am already seeing savings in my gas bill! I couldn't be any happier with their work.

Rob did extensive work for us in 2011 and is doing more now.

Both the work & service were terrific (we especially appreciated his helping us navigate the complex Mass Save reimbursement process). 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. Finally, this is just icing on the cake, but you couldn't find a nicer, smarter, more conscientious & honest guy to have around the house.

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.
