Celebrating 70 years!

JM of New Bedford is Celebrating its 70th year as a family business! Elwell Perry established his multi generational insulation business in 1951 and at the time called it “Insulation inc.” At the time the company was a Johns-Manville certified insulation installer. In 1987 Elwell Perry Sr. retired but his son Elwell Perry Jr. continued weatherizing homes in the South coast and Cape Cod. Today the third generation, Matthew Perry is working with the company to keep up the same high quality level of insulation and weatherization installs. As a result of our 70 years of experience, there isn’t a situation we haven’t seen so feel free to call us with any questions you may have to make your home healthy and energy efficient.

We provide FREE estimates and no project is too small.
