On Angi, the company describes itself as specializing in insulation installation and upgrades. Its MA HIC license 220700 is active on the state registry, with RS INSULATION CORP as the holder of record. A customer replacing an AC unit needed cellulose insulation removed from a tight attic space; they say the sales rep, Blake Cannon, quoted a reasonable price for the removal, and the RS guys came on a Sunday, laid down plastic and cleaned up after. The same customer then had the attic rafters spray foamed and says that job took 2 hours. A customer who had spray foam insulation installed and old insulation removed wrote that RS and Blake had the best deal. A 2026 reviewer wrote that the insulation team worked on their basement, did the work thoroughly, left the space clean and explained everything clearly. In a 2025 review, a customer described spray foam installed at a house of a little over 10,000 square feet and said the job was done in a timely manner.
Spray foam insulation and removal of old insualtion. Blake was a pleasure, totally professional. Met a bunch of other unlicensed contractors trying to get a better deal. Found that RS and Blake had the best deal and did a superb job. Very happy!
We had a great experience with RS Insulation. We were replacing our AC Unit & needed to remove cellulose insulation in a tight attic space. Shawn Harris Enterprises recommended RS Insulation. RS Sales Rep (Blake Cannon) quoted us a reasonable price for removal. We were on a tight schedule, Blake worked his magic and the RS guys came on a sunday. They laid down plastic & cleaned up after. We then got a reasonable price from Blake to have them Spray Foam the attic rafters. The job took only 2 hours. Thank you guys, great job ! We highly commend RS Insulation !
The insulation team did a fantastic job on our basement today! They were professional, efficient, and clearly knew what they were doing. The work was done thoroughly, the space was left clean, and everything was explained clearly. Highly recommend them if you’re looking for quality insulation work.
Great insulation company! RS Insulation did a very good job from start to finish. The team was friendly, on time, and worked hard. The quality of the work is excellent and everything was done as promised. I am very satisfied and would definitely recommend RS Insulation.
I don’t often leave reviews! I was so Excited to See the Spray Foam installed! Great product! Very impressed with everything RS insulation did at my little over 10,000 sqft house. They were clean, polite, and the job was done in a timely manner! Would recommend them to family and friends. The entire crew is helpful. From the owners to the sales team and even the installers were a pleasure to deal with !
