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!!

David Chase

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 does insulation really do?

It is one of the most cost-effective ways of saving energy and helping reduce heating and cooling bills. In addition, it adds to the thermal and acoustical comfort to your home.

What are the main areas in a house that should be insulated?

First priority should be the attic, followed by the exterior walls, basement and/or crawlspace. Additional areas that need insulation include kneewalls, kneewall floors, sloped walls, cathedral or vaulted ceilings, and cantilevers.

What is an R-Value?

The amount of insulation installed is specified by an R-Value. This is a measure of the ability for the insulation to resist heat traveling through it. The “R” stands for resistance to heat flow. The higher the R-Value the better the thermal performance. Different climates and locations can require different R-Values.

What R-Value is recommended for the Connecticut area?

In the Attic, at least an R-49, exterior walls R-15 and basements and crawl spaces R-21

What insulation products do you use?

We use blown Class I Cellulose called Green Fiber Sanctuary. Cellulose insulation is an excellent choice because it is eco-friendly, made primarily from recycled paper, and treated for fire and pest resistance. It provides superior thermal performance, effectively sealing gaps and reducing air infiltration for better energy efficiency. Its dense composition also enhances soundproofing, creating a quieter and more comfortable home. Plus, it’s a sustainable option that reduces environmental impact while delivering long-lasting insulation benefits.

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.

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.

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.
