East Haddam's Insulation Pros — Real Results


Why Connecticut homes need a different approach
East Haddam brings together historic homes, river moisture, wooded terrain, and plenty of older rooflines. Many houses need insulation that respects original framing while solving modern comfort problems like cold rooms, damp basements, and under-insulated attic slopes.

Frequently Asked Questions?
Why do East Haddam historic homes need a careful insulation strategy?
Older homes have original framing, irregular cavities, and moisture-sensitive materials. Insulation must improve comfort without creating trapped condensation inside historic assemblies.
How does river moisture affect East Haddam insulation projects?
Homes near the Connecticut River or wooded low areas often have damp basements and crawlspaces. Moisture control must come before insulation upgrades in these locations.
What causes cold rooms in East Haddam homes?
Cold rooms come from under-insulated attic slopes, leaky knee walls, rim joists, or additions not tied into the main thermal envelope. The attic transition points are usually the first place to check.
Can older East Haddam homes be insulated without damaging historic details?
Yes. Most comfort upgrades happen in attics, basements, crawlspaces, and hidden cavities without affecting the home's visible character.

Reviews from our customers over 48 years
We had a moldy attic that was going to cost a lot to remediate, and since the roof needed replacing anyway, we decided to tackle everything at once. Nealon Insulation handled the insulation replacement and treated the remaining moldy spots after the new roof was put on. Our old insulation had just been tossed up there with big gaps everywhere, but Nealon’s crew did a thorough job and made the space look MUCH better. After getting multiple quotes, Nealon came back significantly cheaper than another company offering essentially the same scope of work. The team’s communication was excellent, they patiently walked me through the different ventilation options (I had gotten a lot of conflicting advice), and their explanation made the most sense. The only hiccup was a small hole accidentally put in our ceiling during the work, but they had a contractor out within two days to patch and paint it. You’d never know it was there. Overall, it was a great experience, professional, responsive, and fair-priced. I’d definitely recommend Nealon Insulation!
"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.
