As a contractor on a tight remodel timeline, I needed insulation done quickly and this company delivered. Professional, on time, and flexible when schedules shifted. Brian was informative, responsive, and easy to work with. Quality work and reliable service! I’d absolutely recommend them and will be our “ go to “ for future projects.
Brian Lynch and his crew are amazing and efficient. I particularly appreciate his knowledge of insulation materials, Connecticut micro-loans, and tax benefits. His expertise helps us insulate cost-effectively. The crews are on time, answer all questions, and clean up well after the job is finished. I would choose Koala Insulation of Southern Connecticut again. I highly recommend.
Brian Lynch of Koala Insulation came to my home to look at a family room in need of insulation. He was friendly and knowledgeable and we hired him on the spot. The crew and resulting job was all we could have hoped for. I strongly recommend them! We are very satisfied customers

The New England Performance Insulation (NEPI) was prompt well mannered and friendly. When they were done they cleaned up and left the jobsite cleaner than it was before they started. The whole experience with NEPI very good and I would recommend if you need insulation work that you include them in the list of contractors to get quotes from.
After getting several estimates I chose NE Performance Insulation for my project because of their pricing, understanding the scope of the job, and I support Veteran-owned businesses. Thank you for your service! Carol handled the scheduling, and was able to move my job up by 2 weeks, it all worked out great. Communication was excellent, always a quick response. The guys came and finished the job in one day. No problems. The next day I told Carol everything looked good, but there were some areas that needed to be cleaned up, etc., thinking I’d just have to do it myself. She got right back to me and set up a time for them to come back. THAT’S why you should use these guys!
Yesterday, New England Performance removed 20+year old fiber insulation and replaced it with new insulation along the entire length of my undercrawl space, and sprayed exterior foam under the shingles. The job was long overdue. Three very nice young men cleaned out my crawl space, completed the job by mid-afternoon and the BRS dumpster was gone by 3pm. Highly recommend New England Performance for your insulation needs.

USA insulation did a wonderful job on my Condo with insulated of the entire unit… Dominik Doel and his coworker worked efficiently and very professionally trained in what they had to do… Most definitely will refer to my friends here in my Complex… Thank you..
The whole team at USA Insulation of CT was great to work with. Karissa was diligent about keeping me aware of things via phone and text, Matt did a fantastic job of determining our insulation needs and walking us through the process, and Benny and his team (Dominick, Julio, Joey, and Darian) were extremely efficient in getting the job done properly. Seriously, I work from home and it was like they weren't there at all! They got to my place right on time, set things up, got to work, and cleaned up so well after they left the place nicer than they found it! Of course, along with fantastic customer service, the insulation has already begun to pay off. Our new home had only about 5 inches of insulation in the attic (yikes) and barely any insulation at all in most of the walls (double yikes!). How the previous owners managed to survive living like this is beyond me. We realized we needed to check our insulation more thoroughly after the ac was struggling to keep our second (and main) floor below 82 degrees. We're able to track and monitor when our ac cycles on and off. Since installing the insulation just yesterday, there's already been a noticeable dip in the amount of times the ac has had to cycle on. Even now, it's 90 degrees outside while inside it's a comfortable 72 degrees. And the last time my ac had to cycle on to keep it there was... an hour ago for about 15 minutes. That is a MASSIVE improvement. So to USA Insulation of CT, you have our sincerest thanks for making our first house feel like that much more of a properly comfy (and cool) home!
Workers arrived at scheduled time and did an outstanding job. Answered any questions and concerns before starting. They proceeded to perform their work and finished efficiently. Did some extra clean up when finished and gave a thorough walk-through to explain their work. Everything was done to great satisfaction
