Old Lyme's Insulation Pros — Real Results
Why Connecticut homes need a different approach
Old Lyme’s historic homes, coastal marshes, and shoreline humidity make insulation work especially sensitive. Many houses have older framing, low attics, and moisture-prone basements. The goal is to improve comfort without trapping damp air in a home built to breathe differently.

Frequently Asked Questions?
Why do Old Lyme homes need insulation that respects historic construction?
Old Lyme has many older and historic homes where original framing, low attics, and moisture-sensitive materials require careful treatment. Standard approaches can damage what they are meant to protect.
How do marshes and shoreline humidity affect Old Lyme insulation?
Damp coastal air affects crawlspaces, basements, and attics in Old Lyme homes. Moisture control and ventilation are essential components of any insulation plan here.
Can insulation improve comfort in Old Lyme historic homes?
Yes. Attic air sealing, crawlspace improvements, and basement rim-joist work improve comfort without altering the home's historic character.
What should Old Lyme homeowners check before insulating?
Check for damp basements, attic staining, blocked ventilation, and any signs of moisture before adding insulation. These conditions must be resolved first or the insulation will underperform.

Reviews from our customers over 48 years
I recently bought a house with asbestos in the attic, and decaying, improperly installed insulation in the basement. Nealon helped me re-insulate both the attic (post-remediation) and the basement, and I could not be happier with the result. They removed and disposed of all the old non-asbestos insulation (asbestos was professionally remediated prior to my contacting Nealon), and installed all new, high-quality insulation all around. Could not be happier with the experience! Good communication, high-quality work, and a reasonable price! Although I was on the wait-list for a while (I understand why they are in demand!), once they started the job they got an impressive amount of work done in a very short time.
"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.
