JM of New Bedford is an insulation and weatherization company whose website names New Bedford as its service area. A 2026 Google customer said Matt and his team came in to get the house prepped for a heat pump system install, including fixing mistakes made by another company that was supposed to remediate mold in the attic.

A 2026 customer thanked Matt for the job his team did insulating the whole house and said they left everything clean at the end.

Its Massachusetts home improvement contractor registration, number 103195, held by JM OF NEW BEDFORD COMPANY, INC., is active on the state registry. A 2023 customer said Matt inspected the house and found no insulation on the second floor, and that Jared and his crew then insulated the second floor, the attic and the basement. In a 2023 review, a customer said the crew had to drill holes in the walls from inside because of brick, and cleaned up after. A 2024 customer said they used the Mass Save program to have the attic and walls fully insulated and chose the company rather than have a contractor randomly assigned. A 2025 customer said Matt did the assessment and Derek and his team completed the work. A 2023 customer said the company insulated the house and installed weatherstripping throughout through Mass Save, and was considerate of a toddler and pets.
Matt and his team came in to get our house prepped for a heat pump system install. JM went way above and beyond to get us ready, including fixing mistakes that were made by another company that was supposed to remediate mold we had in our attic. Due to the tight timelines of the other work being done, we were nervous that the mold and insulation would set installation back. Matt moved things around and got us back on track. High recommend for JM of New Bedford.
Thank you Matt for the great job your team did, insulating my whole house this week. They were professional and definitely know their job. I would recommend them to family and friends. Also left everything clean at the end. Thank you. Maria Machado
Matt came out to do our assessment and was communicative and helpful answering questions throughout the whole process. Derek and his team came out to complete the work. They were cordial, professional, and respectful of my home. Top to bottom this company knows what they are doing when it comes to insulation, and hiring staff. Anyone going through the MassSave process, these are your guys! Easy 5-star review.
After purchasing a house in 2022, I took advantage of the Mass Save program to have my attic and walls fully insulated. Rather than having a contractor randomly assigned through the program, I did some research and chose JM of New Bedford. I was very happy with the job they did, and the team was very professional while performing the work. It was during the Summer, and it was over 110 degrees in the attic, so not easy conditions to work in. I'm glad I chose JM of New Bedford, and I would definitely recommend them to anyone looking to insulate their home.
I just had my home fully insulated through Mass Save and I was skeptical on who they would send to service my home. I was very fortunate to have JM of New Bedford a Weatherization Co. to do the work. To be able to work with Helder and Derrick throughout this process and when I say these gentlemen were true professionals and craftsman at what they do. They took the time to really walk me through everything they were performing on my home. Not only professional at what they do, they also made me feel like I was part of their family and really made sure that the job was done correctly as if it was their own home. The knowledge they bring, definitely showed on the work they performed. JM of New Bedford is for sure on my top 3 companies list, that I would work with again and would recommend them to anyone looking to improve their home. I really hope this review reaches the right people but again, BIG THANKS! to Derrick and Helder for a great experience! -Dev C.
