Durham’s Insulation Pros — Real Results


Why Connecticut homes need a different approach
Durham’s rural setting means larger homes, older farmhouses, and more exposed attics and crawlspaces. With less coastal moderation, winter drafts show up fast. Insulation here needs to focus on building-shell tightness, attic depth, and sealing the oddball gaps old homes love to hide.

Frequently Asked Questions?
Why do Durham homes need strong draft control?
Durham's rural inland setting brings colder winter nights and open-lot winds. Air sealing is especially important in attics, basements, and crawlspaces because these areas drive most of the cold.
What insulation issues are common in Durham farmhouses?
Irregular framing, leaky attics, stone foundations, and additions that were insulated unevenly — or not at all — are common. Each area needs its own diagnosis.
Do Durham homes with crawlspaces need insulation?
Yes. An unsealed crawlspace drives cold floors, drafts, and moisture problems. It needs to be sealed, insulated, and separated from outdoor air correctly to perform.
Can insulation help large Durham colonials with high energy bills?
Yes. Large attics, bonus rooms, and garage ceilings waste significant heat when under-insulated or poorly air sealed. These areas offer the best return on insulation investment.

Reviews from our customers over 48 years
The guy who came to do an estimate for blown-in insulation was by far the most thorough and knowledgeable so we went with Nealon. Great crew, they worked hard to get it done and cleaned up after themselves. Glad we went with them. Hoping to have them back for another job in the near future.
"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.
