Since 1951

Our family started in the insulation business in 1951 when Elwell Perry Sr. founded Insulation Inc.; a company specializing in re-insulating homes with fireproof mineral wool.Mr. Perry managed the company for thirty-five years, always striving to perform high quality services that achieved the maximum results for his customers at a fair price. Since his retirement in 1987, Elwell Perry Jr. has been providing the same level of quality and value for which the company has come to be known. In the spring of 2010, JM of New Bedford welcomed Matthew Perry, the third generation.
"Customers place a lot of trust in people when they engage them to do work on their homes. It’s refreshing to work with someone who cares about what he is doing and wants to make sure things are done properly and to the customer’s satisfaction."
Elizabeth John
"I would like to express my appreciation and my many “thanks” to you and your company. Your workers who performed their duties at my home exemplified professionalism, care and diligence in their work ethics which speaks volume representing your company."
