Superior Insulation describes itself on its BBB page as specializing in all aspects of insulation and weatherization product installation for both residential and commercial clients. It holds a 5-star average across 10 Google ratings, and its BBB page shows an A+ grade and accreditation. Its Massachusetts home improvement contractor registration, number 175445, is active on the state registry. A recent Google customer went through the Mass Save program, had Superior Insulation assigned as the contractor, and said they cleaned up after themselves. A 2026 customer said they performed a full evaluation, insulated and sealed everything in the house, and did a before and after test to show the results. That 2026 customer also said everything was explained in layman's terms. A 2023 customer named Bill P., Vinnie and Chris and called them professional and hard working from beginning to finish. A 2023 customer matched with the company through MassSaves wrote that they would use it as a contractor for additional insulation work rather than have MassSaves assign one. A 2021 customer, whose insulation came after a Mass Save energy audit, wrote that some areas could not take insulation because of a previous install and that the final price was adjusted rather than the savings pocketed.
I would highly recommend Superior Insulation- we went through the Mass Save program and were fortunate enough to have Superior Insulation assigned to us as a contractor. Very knowledgeable, very honest, cleaned up after themselves. Extremely pleased with their work.
They came to my house, perfomed a full evaluation, insulated and sealed everything in my house, and did a before and after test to show the results. It was amazing to feel the difference. Everything was explained in layman's terms. I could not be more satisfied with the service Superior Insulation did.
Bill P. , Vinnie and Chris were nothing but amazing! Professional and hard working from beginning to finish.
I was matched with Superior Insulation through the MassSaves Program, and I could not have been luckier. Their service was excellent, and their quality of work was amazing. If I need additional insulation work done, I would use them as a contracter rather than having MassSaves assign one to my house.
I had Mass Save do an energy audit and they had Superior Insulation provide the insulation services. The crew was on time and polite and very efficient. The quality of the work done was top notch. There were areas where they could not add insulation due to previous install. They adjusted the final price and did not try to just pocket the savings, great honesty. I would definitely recommend them to others.
