New Haven's Insulation Pros — Real Results
Why Connecticut homes need a different approach
New Haven’s insulation challenges come from older multifamily homes, historic districts, flat roofs, and dense urban construction. Many buildings have difficult access and aging wall systems, so the priority is often strategic air sealing, attic work, and moisture-safe upgrades.

Frequently Asked Questions?
Why are New Haven single-family insulation projects often more complex?
New Haven has many older detached homes, historic houses, flat roof sections, and dense neighborhood lots. These conditions limit access and require more targeted insulation solutions.
What insulation upgrades help older New Haven homes most?
Attic air sealing, basement rim-joist work, roofline insulation, and targeted cavity work make the biggest comfort difference in older detached homes.
Can New Haven's older detached homes be insulated effectively?
Yes. The plan must account for old framing, attic access, basement conditions, ventilation, and whether finished upper floors are part of the thermal boundary.
Why do New Haven homes with flat or low-slope roof sections need special insulation planning?
Flat and low-slope roof sections trap moisture when insulated incorrectly. The roof assembly must be understood before any insulation method is chosen for those areas.

Reviews from our customers over 48 years
From start to finish Nealon Insulation was a pleasure to work with. Jen extremely responsive and helpful through out this process. Asking all my questions through out the process along with scheduling. Dave did a very thorough job with the initial inspection. Walking me through the process and explaining each aspect. Dan, Eddie, and Adonis did incredible work on the job overall. They were knowledgeable, efficient, punctual, and a pleasure to collaborate with. Finally, Chris came in and finished the job in a very timely manner the following day. Overall this company has a wonderful team and I would highly recommend Nealon Insulation to anyone.
"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.
