Frequently Asked Questions?
Do I really need to insulate my garage in Connecticut?
Yes, you should insulate your garage in Connecticut to keep it warmer in winter and cooler in summer and protect the thermal barrier of your home. Insulation is especially important if the garage is attached, has rooms above it, or is used for more than parking.
What’s the best type of insulation for a garage?
The best type of insulation for a garage depends on the setup. Spray foam or dense-packed cellulose works best for finished walls, offering high performance. For open framing, fiberglass batts are affordable and easy to install. Your goals and garage use will determine the best fit.
Will insulating my garage lower my energy bills?
Yes, insulating your garage can lower energy bills by reducing air leaks into your home. Sealing the ceiling and shared walls helps your HVAC system work more efficiently, cutting heating and cooling costs.
Can I insulate just the garage door?
Yes, you can insulate just the garage door, and it helps slightly. However, if the walls and ceiling are uninsulated, most heat will still escape. Door insulation works best as part of a full garage insulation upgrade.
Will insulation help with noise from the garage?
Yes, insulation helps reduce noise from the garage by adding a sound barrier. It’s effective for blocking sounds from power tools, music, or general activity, preventing noise from echoing into the rest of the house.
Is it worth insulating a detached garage?
Yes, insulating a detached garage is worth it if you use the space as a workshop, gym, or for storage. Insulation helps stabilize temperature and protects tools and supplies from extreme heat or freezing conditions.
Can I insulate my garage myself?
Yes, you can insulate your garage yourself if the walls are open and you use fiberglass batts. For air sealing, spray foam, or moisture issues, professional installation is recommended to ensure proper coverage and performance.
How much does garage insulation cost?
Garage insulation in Connecticut typically costs between $1,500 and $5,000. Price depends on garage size, insulation type, and whether the space is finished. We offer free quotes to give you a clear estimate based on your project.
Reviews from our customers over 48 years

Nealon did an outstanding job in terms of courteous services, as their team members, as well as Chris who was responsible for directing the job, were most professional!!! They cleaned up nicely, and my goods remained intact. Also and happily stated, it’s been one week since they’ve installed insulation in our home, and we notice a huge difference in the amount of energy we are using for heating…which equates to $avings!!! In short, we’d use them again, and glad we chose them for this endeavor!!!

Highly recommended. Their estimate was competitive, the work was done in a timely and clean manner, they explained what was done, and our house is warmer as we head into the winter. When we had a question, they came back out to talk with us and helped us answer our questions. I will use them again and recommend them to anyone.

They are an amazing company to do work with! Jen in the office is polite, pleasant, and very competent. The work was done well and very quickly. We had our attic and basement insulated. I would 100% recommend!

The Nealon team was professional and considerate of my property. I noticed a 200-kilo watt decrease in my electric bill along with an additional savings in oil consumption of 50 gallons. No more drafty cellars and so far, the mice have gone elsewhere.

Fast, efficient and great price! Didn’t even notice them insulating our attic and making a big difference already! Would highly recommend for anyone that wants to cut down on their energy bill!!
