Cromwell’s Insulation Pros — Real Results
Why Connecticut homes need a different approach
Cromwell’s location near the Connecticut River means some homes face damp basements, mixed-age construction, and tricky transition spaces. Ranches, colonials, and split-levels are common, so insulation often needs to address attic bypasses, garage ceilings, and moisture-prone lower levels.

Frequently Asked Questions?
Why do Cromwell homes near the Connecticut River need a different insulation approach?
River-area homes deal with damp basements and seasonal moisture. Insulation should include air sealing and moisture checks before any material is added.
What insulation issues are common in Cromwell split-levels?
Split-levels have tricky garage ceilings, short attic spaces, rim joists, and transition areas where heat escapes and cold air enters. Each transition point needs its own assessment.
Can attic insulation fix cold rooms in Cromwell ranch homes?
Sometimes, but cold rooms also come from air leaks, thin insulation over garage spaces, and poor attic ventilation. The full thermal boundary needs to be checked, not just the attic floor.
Should Cromwell homeowners insulate basement rim joists?
Yes. Rim joists are a primary source of drafts and heat loss, especially in homes where the basement feels cold or damp. Spray foam is the most effective material for this application.

Reviews from our customers over 48 years
The Nealon team has been great to work with. The office staff was responsive and the team that came out to install our insulation could not have been more professional and thorough. They were very transparent in pricing and walking us through the work that was to be done, and they really delivered as promised on the job. Highly recommend them!
"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.
