Koala Insulation Of Eastern Connecticut
It’s natural to get spooked the first time you get a high energy bill. We’ve all been there: Unsparing use of the thermostat in extreme weather conditions seems like such a good idea at the time, but that end-of-the-month payback truly packs a sticker shock punch. But if you’re living in the Norwich, Groton, or Vernon Rockville areas, you no longer need to take those high energy costs as a given. Koala Insulation is here to help you.
As one of the nation’s leading home insulation contractors, Koala truly understands the impact eco-friendly, all-natural temperature and air control can have on your home. It’s one thing to rely on the thermostat, but simply allowing air to flow freely from one end of the house to another gives the homeowner an unmatched layer of freedom. Insulation exploits the structure of the house itself to regulate airflow, preventing leaks, trapped air, pockets of heat, and all the other obstacles standing between you and the comfortable indoor temperature you deserve.
The highest level of quality begins with Koala’s commitment to your satisfaction. Our customers all benefit from the Koala guarantee, which is devoted to high-quality service, transparent pricing, and an accelerated schedule. This commitment touches every project that we take on. You’ll never be unable to reach a team member who can answer your questions.
We proudly offer:
- Spray foam insulation: Thickly layered to stop air gaps in their tracks.
- Blow-in insulation: Uses thick cushions of insulation material for additional padding and effectiveness.
- Batt insulation: Layered through your walls like padded sheets so it can manage airflow brilliantly.
- Air sealing services: Prevent cracks from leaking your precious airflow.
- Attic insulation service: Built to target those hard-to-reach areas.
- Solar attic fans: Pushing hot air out and bringing cool air in — this is their sole reason for existence, and we know how to install them the right way.
- Insulation removal: Old insulation can actually make indoor temperature control harder. Koala can take care of that for you.
- Crawl space insulation: Helps keep your entire house airtight.
- Builder services: We can execute a wide range of home construction and renovation tasks. Just tell us about your project!

No One Should Have To Live With Bad Insulation
Life with poor insulation means a constant struggle against uneven temperatures in the home. Summer or winter, you’ll find different parts of the house hotter or colder at different times of the day, forcing your family to shuffle around uncomfortably just to stay sane. It can become a real struggle, and the impending pressure of a high energy bill can only worsen the situation.
The point of Koala’s home insulation services is to create a more natural indoor climate in your home. Reliance on heating and air conditioning is all well and good until you find out about their intense financial and environmental impact. Insulating your home — which often means removing insulation from the walls to replace expired insulation material — is the superb, time-honored way of beating those weather odds.
Enjoying the Koala Advantage
Your journey with Koala begins with a call to our home office to explain your needs. We’ll send a licensed assessor to your home to look at the property and develop a fair estimate of services. The layout of your house has an enormous impact on the kind of insulation we install, as well as the manner in which we install it, so this stage is crucial for success. Once that’s achieved, we’ll agree to a service appointment and see you on the scheduled day.
That’s all there is to start enjoying our services. With Koala Insulation, you’re only a phone call away from enjoying smooth airflow like your home has never seen before. Call us today to begin.

Sean, Nick and his team were incredible! Nick especially went above and beyond to ensure my soggy insulation was aired out properly under my mobile home before the job was started. They did a fantastic job, left the area nice and clean and did the job with a smile on their faces! I highly recommend. Will use again if the need arises.

We got closed cell spray foam on our entire roof deck on a residential retrofit. Nick and Sean were fantastic. Nick (the sprayer) was honest and trying to save us money, and willing to answer many questions and offer references for his work. He was responsive in checking in on daily progress while we were away. Sean (owner) was also very helpful in going back and forth in figuring out difference foam depths and adjusting quotes as needed. I'd definitely recommend them and use them again. Our carpenter who did some finish work after them said they did a great job. Inspector as well.

I had my blown-in insulation taken out of my attic and my basement spray foamed. I am ecstatic about the work that was completed by Koala Insulation of Eastern Connecticut! I highly recommend this company. Sean, the owner is very down-to-earth and eager to please his customers, and I can say the same about Nick & Co. These guys are AMAZING and worked so hard to get me the results that I was looking for, they went above and beyond, and I am super happy with the results!

Sean and Nick were fantastic to work with. This project ended up having several unexpected complications that could have easily derailed things, including issues with roof venting, improperly installed drywall, and coordination challenges involving permits, the building department, and septic requirements.
They did not walk away or cut corners. Instead, they worked through every issue with me, stayed flexible on both pricing and scheduling, and put in long days to keep things moving forward.
What really stood out was their willingness to go beyond the scope of the job. Even when something technically fell on me as the homeowner, they took the time to explain options, problem solve, and make sure things were done the right way. I learned a lot through the process.
I am confident that many companies would have either walked away or taken advantage of the situation. Sean and Nick did the opposite. They stuck with it and delivered a great result with integrity and pride in their work.
Highly recommend.
