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. Also known as "rockwool, " this product is made from recycled steel slag, and is the only fireproof non-moisture absorbing, heavy density loose fill insulation.
Through our 70 year history, we have worked on over 11,000 different homes, so there is nothing we haven't seen! But don't just take our word on it, read what our customers are saying about us. Just wanted to let you know how happy we are with the work done on our home. The laborers you sent to our house were absolutely amazing, kind and professional and cleaned up after themselves better than any other contractor to walk through these doors!
Insulating the floor is a very good option if available, it enables you to easily get to the Heat resistance code of R38. It also leaves open the option of raising that value higher in the future. By insulating the floor of your attic you cut off that attic space and no longer heat that area. Insulating Rafters with prop-r-vents is good to create more conditioned space without loosing the roof ventilation. The only down side to Prop-R-vents is that the actual vents take up an inch of space which reduces the potential R-value of that space.
Is your Basement Properly Insulated and Air Sealed? Many drafts and cold air will enter a home through its basement and drive the warm air in the house out. Perfect for hard to reach crawl spaces with dirt floors, or where not a lot of insulation can be added. Basement ceiling insulation is important to keep cold air out and floors warm on first floor.

JM has done work on several of my properties and every project has been nothing less than top notch. They are in their 3rd generation of family management and some of their staff have been there for decades! Their attentiveness and work ethic are one of the biggest reasons they are the best in the area. Matt Perry is always willing to swing by to look over the job and nearly everything I asked could be done was addressed by his crew members. Plus using the 75% off Mass Save Insulation incentive was awesome as the jobs nearly paid for itself in less than 2 years.

An amazing group of laborers work for this establishment! I cannot recommend them more highly! The owner called me to check on how the job was going! Outstanding customer service! I know where I will go if I ever leave this house and need insulation! With the job they did I will never need to update the insulation!

The team insulated our home yesterday and today. They were prompt, professional and polite, best of all I never saw a cell phone in their hands the entire time they worked here. They took great care with the inside of our house by laying down plastic on the floors where they worked, they vacuumed the areas when they done. Outside they were considerate of our landscaping and didn't bend a single flower stem. I wish all companies would work with this level of professionalism. Hats off to the crew and their boss Matt.
