I never write reviews, ever. I had to write this one because I was honestly blown away by this company.★★★★★ 2 weeks ago
It started with Sean coming over for what I assumed was … Read More just a standard quick inspection. He didn't just look around, he actually installed 6 new thermostats in my house right then and there, completely for free (to me). That set the tone for the whole experience, and the crew that came later really amazed me also.
Jack and Jacob contacted me when they were on the way, showed up exactly on time, and worked harder than I expected was possible. They had to fully insulate the house (attic, 2nd floor, 1st floor, basement, and an outside crawl space). The weather was miserable. It was absolutely freezing outside, and then it started pouring rain. Jack and Jacob were up on ladders, freezing and soaking wet, and they just kept working without a single complaint. They honestly could have taken the easy route and drilled through my inner walls to get the job done fast. Instead, they chose to do it the hard way to make sure they didn't destroy the inside of my house. They took the time to remove the vinyl siding, drill from the outside in, and then put the siding back on perfectly. You just do not find people who care that much about your home anymore.
Jack was incredible at keeping me fully updated through the entire process so I never had to guess what was going on. It turned into a massive project. What was supposed to be a 2-day job turned into 4 days of them working morning till night. They stayed until it was done right, they were extremely polite and knowledgeable the whole time, and there was zero upcharge for the extra days of labor.
Jack, Jacob, and Sean are the absolute stars of the show here. These guys are who you want to work on your home, period. -

I’ve had Mass Save energy audits in the past, but my experience with Colt Home Services was by far the most informative. Joe arrived right on time and conducted … Read More a very thorough assessment.

The review/ estimation process was quick, easy and straight forward. But during the actual work, since our house is brick outside, they drilled holes inside, yet … Read More they often skipped pumping the insulation materials and just covered the holes. After finding out, we had to monitor their crew all the way until the project finished to ensure they do not skip!★★★★★ a month ago
We didn't notice at first, so our second floor properly just got 70% of the supposed insulation....
So you want to make sure to monitor/follow the project.
- edit: the customer service is super helpful and listening to our concerns. They want to come for quality check and provide any reparations if necessary.
-edit 2: after the QC visit, the team agreed that we indeed needed improvement! And they came back for the work within the week. We are very happy with the service this time.
