Review 1
I was recommended by another contractor that Graham was a good contractor that was eligible for the Mass Save program that I used. I don’t normally leave reviews but I highly recommend Graham Built for insulation installation because not only were they on time, they were also very clean, efficient, and knowledgeable. Most contractors I’ve dealt with since I bought my home last year has either never cleaned up after themselves or have damaged something on my property due to negligence but this wasn’t the case with Graham.

They’re extremely friendly and take pride in their work so they’re definitely on top of my list for insulation work.

Review 2
If I could give Graham 10 stars I would. I hired them for insulation in my attic and underneath my house. The team of five showed up on time and prepared to immediately jump into work. They have all been incredibly professional, polite and neat. I work from home and there have been very few disruptions other than the normal course (a little noise from equipment, etc.). I would highly recommend Graham for all your insulation needs. These compliments extend to Chris the owner who called me to check on my satisfaction and Nancy the Office Manager who was so helpful guiding this first timer through the process. Double thumbs up from me!
