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!

Timothy Saunders

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.

Christine

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!!
