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.

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!!

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.

Frequently Asked Questions?
What if I don’t know what is existing in my walls, can you find out?
Yes, we would first ask when your house is built as that is a determining factor. Building codes started in 1971 in Connecticut so anything prior most times is empty unless renovated, but in between years may so we can provide you with a wall test. This is where we would remove a couple rows of siding or pieces of clapboard, drill a 2 1/8” hole to see what is inside and replace the siding. We can add here, we usually charge $150 for a wall test, which we would credit to the job if they were in need of insulation and went with us. You can also choose to get an energy audit to have a blow-door test to find out your insulation needs. This is related to the insulation rebates available and more information can be found at energizect.com.
How do we remove insulation in an attic space?
If the insulation existing in an attic space is batting, we bag, seal and haul it out of the attic space. If the insulation existing is blown, we use a Hepa Vac System, in which we vacuum out from the attic through a hose the insulation, which is collected in a Hepa vac bag outside the premises and hauled away.
Can you be home when the insulation is installed?
You can stay home during insulation installation because the process is minimally invasive and generally quick. Insulation is installed using equipment designed to contain dust and debris, ensuring a clean and safe environment. Nealon also takes precautions to work efficiently and respect your space, allowing you to go about your day while the work is completed.
