North Haven's Insulation Pros — Real Results
Why Connecticut homes need a different approach
North Haven’s homes range from older capes and ranches to larger colonials, many with attic bypasses, garage rooms, and basement rim-joist leaks. Its location near coastal and river-influenced areas means moisture control still matters, even away from the beach.

Frequently Asked Questions?
Why do North Haven homes often need attic and garage insulation?
Many North Haven capes, ranches, and colonials have attic bypasses, garage rooms, and basement rim-joist leaks that drive most of the comfort problems. These areas need to be addressed first.
What causes cold rooms over garages in North Haven?
Cold garage rooms come from poor air sealing, thin garage-ceiling insulation, and open framing paths connected to the attic. All three need to be addressed to solve the problem.
Can insulation help North Haven homes with basement drafts?
Yes. Rim-joist insulation and basement air sealing reduce cold air movement and improve first-floor comfort directly above the basement.
Do North Haven homes need moisture control even away from the beach?
Yes. Coastal and river-influenced humidity still affects basements, attics, and crawlspaces in older homes, regardless of distance from the shoreline.

Reviews from our customers over 48 years
The team did a great job with my attic insulation. Jen was fantastic in helping from an administrative side, getting the rebates prepared etc. Dave was great at coming out and giving me different ideas and ways to have a storage area while staying in budget. Bennet was very friendly, has a fantastic personality and incredibly knowledgeable. Even though there were two issues with the ceiling at the end, they got someone out right away to fix it. Highly recommend this honest and great team of people.
"They did great work they were in and out in no time and they cleaned up afterwards very happy with them"
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!!
Great experience! Very friendly and professional. They were on time, stuck to their quote and work timeline and have done a great job with two projects for me. I would definitely recommend.
