Koala Insulation of Central Connecticut

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 ele

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 b

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 apprec

From start to finish, it was a pleasure dealing with this company! I initially spoke to Graeme who was very professional, courteous, answered all of my questions and addressed any concerns. I appreciate the excellent communication regarding job scheduling, payments/receipts, and a follow-up call after the job was completed--very thorough! Steve (Estimator) quoted us for blown-in cellulose insulation and insulated covers for our recessed lights as he explained this would be the best solution to address our needs. Steve was professional, courteous, highly knowledgeable, educated us on what was going to be done, answered all of our questions and we received our estimate the next day, which was very reasonable! The crew, Tony and Chris, were professional, courteous, hard-working, answered

The guys came out to spray the basement. They were in and out. They setup plastic to make sure they didn’t leave a mess and cleaned up very nicely. Very happy especially since it made a huge difference before the old streak came. A yes as everyone always looks for price was very fair. They don’t know it but they’ll be back when we finish our sunroom.
