Roofing Pros with 60+ Years of Experience

We expertly install our own stone-coated steel replacement roofs designed to stand up easily to whatever the Connecticut weather brings. Enjoy the protection of this ultra-durable roof, along with impressive curb appeal and easy maintenance. You’ll also have total peace of mind knowing the roof is covered by a lifetime warranty!

Premium Attic Insulation

About 90% of homes in the U.S. were found to have insufficient attic insulation; make sure yours isn’t one of them! Up to 25% of heat escapes through the roof, so don’t go through one more Connecticut winter paying too much for your heating costs. Premium insulation makes it easier to keep your home warm and comfortable while shoring up your home’s energy efficiency.

Energy-Efficient Replacement Windows in Connecticut

Are your windows more than 10 years old? If so, you could be letting money go right out the windows! NESCOR installs high-performance windows that prevent air leakage, so even when the temperatures dip below freezing, you’ll be able to keep your home warm without putting extra stress on your heating system. We expertly install many window styles, and our replacement window company has the perfect option for every room.

Stylish, Secure Replacement Doors

New doors might seem like a small home improvement, but they make a big difference in your home's style, security, and energy efficiency. Whether you want a new front door, storm door, or patio door, we have what you need. Our experienced team provides flawless installation backed by industry-leading warranties, no matter what kind of door you choose.
