Spray Foam Insulation in Hartford, CT

Look no further! If you need foam insulation at a great rate, this is the crew for you. From start to finish, they treated me with respect, arrived ready to rock, and got my house taken care of. Thank you all so much!

Did an amazing job! Did everything I wanted perfectly and quickly. Couldn’t of asked for a better company. Thanks for everything!

Great company great people. I would no question use them again. Best in the business.

I had a Energize CT home energy assessment done and they said I qualified for an insulation rebate. Out of all three quotes I got, Koala gave me the best price and didn't try to upsell me on things I didn't need which the other companies tried to. The other companies also spent 30+min looking around the house. Koala took 5-10min. Koala came in and did blown in attic insulation as well as blown in wall insulation, all cellulose. Tony and his team were very efficient and professional. They worked very clean constantly using the leaf blower and vacuuming. My house is old built in the 1940s so outlets are in random spots. When they drilled into the house they accidently cut into the outlet. They quickly alerted me to the problem and said an electrician is on their way to fix it. Indeed the electrician came and fixed it. Free of charge. If you are looking for blown in insulation I highly recommend Koala if I buy another house in the future without insulation I will be giving Koala a call.

We had attic insulation work done and I was very impressed with how professional and honest this company was from start to finish. After the installation, they came back with a thermal camera to verify the work and explain what we were seeing, which gave me a lot of confidence. They clearly showed that the attic insulation was performing well and pointed out a few knee wall bays that could be improved, but were upfront that the ROI didn’t justify pushing additional work. I really appreciated that they didn’t try to oversell. There was also a situation where the attic hatch design didn’t allow for the foam board cover specified in the contract. Instead of forcing it, they installed a higher-quality foil-faced fiberglass hatch cover at their own expense and explained why it would perform better. Since the install, the house is noticeably more comfortable, even in rooms without heating, and our energy bill dropped despite colder weather. Overall, this was a very positive experience and I would absolutely recommend them.

I can’t say enough about koala insulation. I first had them at my house in June 2025 for blown in attic insulation. Upon inspection Graeme discovered that the original insulation was laying on top of an old particle board floor. The crew came, removed the old insulation, cut a section of flooring out down the middle to ensure all the joist cavities were blown into. After they vacuumed the upstairs hallway and all the way down to the front door. These two things showed me what a great company they are. Some companies could have not gone the extra step to make sure the attic was insulated properly and just blew onto of the sub floor to save time and money but not Koala. Then cleaning up the house area they were in so well they left no trace they were there was the icing on the cake. I appreciated their work so much I had them back at the end of the year to insulation the exterior walls and again they did an excellent job. Graeme and his crews are professional, kind, thorough, and time efficient. I would recommend Koala to anyone including my closest family and friends. Also you can’t beat their prices, they are worth every penny.

Great company with a wide Variety of options for your insulation needs.The staff was Very helpful friendly and reliable and I would recommend them again Without a doubt

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

Had ecologic come out to do the spray foam work in my attic and basement that we decided to finish. They were amazing and the quality of their work was very impressive. I had a different company do work two years ago on a different area in my house, and was not happy with the final product. Was unsure if I wanted to use foam again, but Rich assured me that I was in good hands with his team. The Crew that came out was very thorough and meticulous. not only was the workmanship excellent, but they left the place Spotless upon completion. I cant recommend these guys Enough!!! Thanks Guys!!

I contacted Ecologic Energy Solutions to have my old attic insulated. Sales rep Richard came out the very next day to give me an estimate which was better than I had anticipated. He was very knowledgeable about updating and suggested I foam the attic roof AND walls. I had gotten other prices from other companies but they were $500-1000 more for the same job. Even better, Richard saw the project out from beginning to end, and the crew that came did an amazing job and left my attic spotless. What more can I say? As I continue to update my house, I will definitely use Ecologic in the future for my insulation needs.

I used Ecologic for spray foam in my addition in this past fall. Of the three companies I contacted, they were the most responsive, knowledgeable and also competitively priced. Their workers were efficient, neat and it was clear they took pride in their work. I'd recommend them to anybody looking for a good insulator, really top notch.
