Wollaston Construction is a Quincy-based insulation and weatherization contractor working through the Mass Save program on air sealing, blown insulation, and mini-split/heat pump installs. Its Massachusetts home improvement contractor registration is active. The reviews describe a consistent crew — Bryan (sometimes spelled Bryon or Brian) and Jose come up by name again and again, alongside occasional mentions of Dillon, Macio, and Jesse — doing attic, first-floor, and whole-house insulation jobs. One detailed December 2024 review described insulating a detached 1802 barn: MassSave's own estimate quoted the walls at 8 inches when they actually measured over 12 inches thick, and the crew caught the discrepancy, remeasured, and worked with MassSave to correct the quote before finishing a job the customer expects to last another two centuries. Other reviews describe roof fan installation, air sealing, and full first-floor blown insulation, consistently citing punctuality, cleanup, and clear explanation of the work. The record isn't perfect: a June 2026 review described a specific communication breakdown with an employee named Kevin, who the customer said spoke with a tenant after being asked to communicate directly with the owner, and BBB — where the company holds a B- and isn't accredited — cites one complaint the company didn't respond to. For an insulation or MassSave-incentive project, Wollaston's reviews point to a crew that knows the program's back-and-forth and catches its own estimating mistakes — just make sure whoever visits the property knows to loop you in directly if you're not on-site.
I am very disappointed with one specific employee at this company. Kevin came out to inspect my property for a crawl space insulation estimate. Before the visit, I specifically instructed him not to discuss any details with my tenants and to communicate directly with me. Unfortunately, he did the exact opposite—he only spoke with my tenant and never contacted me afterward. I waited two weeks for a phone call before finally having to reach out to him multiple times myself. When I eventually got in touch with him, he insisted that he had called me and claimed that I had never told him not to speak with my tenants. I informed him that I have phone records showing otherwise, but he continued to argue with me rather than address the situation professionally. When I asked to speak with a supervisor, Kevin hung up on me. I have never been spoken to in such an unprofessional manner by someone in a customer service role. On a positive note, Dylan in the office (if I have her name correct) was absolutely wonderful to work with. She was helpful, professional, and courteous throughout the process. I genuinely feel sorry that she has to work alongside someone who treats customers the way Kevin did. Based on my experience with Kevin, I cannot recommend this company.
Bryon and Jose made quick work of our full first floor blown insulation installation! They cleaned up and were extremely professional
Amazing management that care about people.
I recently had Wollaston Co insulate my attic. The communication was great throughout, flexible on my schedule and the work was done properly. I would hire Wollaston again.
I recently had Wollaston Construction insulate my attic and I couldn't be more pleased. Bryan and Jose were professional, knowledgeable and efficient. They arrived on time, worked diligently and showed great respect for my home and neighbors. Not only did they complete the job faster than I expected, but they also did a wonderful job cleaning up after themselves. I highly recommend Wollaston Construction to anyone looking for quality work and excellent customer service. Thank you Dillon, Bryan and Jose!
