They explained each step as they went, which gave us complete confidence in the work being done. Highly recommend.

There is a reason Polar Bear is the #1 insulation vendor for Mass Save. Not only did these guys…read morehave the earliest availability than the three contractors I shortlisted, but they worked around my work schedule and holiday travel plans to do my whole house insulation project - which I greatly appreciated as winter was just around the corner. 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.

They replaced some rotted facia board, put down ice/water and roof wrap, sanded and flashed the chimneys too! In the days following, all three of my neighbors approached me individually and inquired about the company who installed my roof, as they watched and were also impressed. All three neighbors are also in need of new roofs. I gave them the number for these guys. This crew was in and out in 12 hours flat and I couldn't be more happy with the job they did.

Rob did extensive work for us in 2011 and is doing more now. His previous work included blow-in…read moreinsulation for exterior walls of our big old historic registry home, and installing new doors + insulation w/ vapor barrier in a new basement-level storage room. 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.

The work they did was impeccable, and they were very thoughtful, considerate and professional throughout. I can't say enough good things about them and the work they do. I look forward to working with them again in the future, and I would recommend hiring Rob and his crew without reservation.

GO ELSEWHERE! Simply put you will get the B Team (at best) and all the forms of sloppiness that…read moregoes with it. Some here have gone into detail as to how you can screw up a basic insulation job, so I won't repeat it. The number of screw ups and amateur work quality was more than I've ever seen in 30 years of home ownership and contractors work. The highlight: they core drilled through structural 2x4s inside the wall, under window framing. Who the F does that?! Everything from communications, to quality of work, to damages, to explanations, to billing / paperwork, slop/mess/clean up, it goes on. Ghosting communications to the office and field lead. Yes, they came back to fill in the various areas where they put NO insulation at all in several wall cavities...but, really, how do you just miss that unless you've been on the job for about a week. The only reason I got them to do that was I got a temperature gun that showed several places where it was a cold wall... They came with a IR image gun and verified various empty areas. What kind of training and qualification do they go through? and oh yea, one of the crew wanted to sit in my hallway for long periods of time, because his feet were very cold and he had nothing to do. When he was 'working' he was on his phone talking and texting non stop. I am not making this up. On each of two crews, there was one person of the three that was competent and able to communicate reasonably well, and two who were not. They meant well, but just not up to the task. Find a real insulation company with a real crew of adults.

Within a week of ABCD contacting them, I had a call to set up an in-home measurement. They came when they said they would and sent a signed quote via email in less than 48 hours. Their crew was professional, efficient, and communicative from start to finish and left the space cleaner than when they got there. 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!
