Welcome to the official website of Kornesczuk Windows & Doors

Do you picture all your household heat whooshing out through your old windows every winter? Or in summer, do you imagine the hot sun streaming in competing with your air conditioning? If the thought of replacing your windows seems overpowering and too expensive, it's no wonder. With all this vinyl-clad and gas-filled jargon, how can you choose? Well, you can have beautiful new windows and save money on energy with Kornesczuk Windows & Doors

Kornesczuk Windows & Doors is a dealer of high quality windows and doors. Contractors and homeowners rely on Kornesczuk Windows & Doors for low costs, product quality and quick service. For new or replacement windows the quality choice is Kornesczuk Windows & Doors.

Our tilt kit system uses about 1/2 of the material that a normal complete replacement window uses. We do not disturb the interior trim. In many cases, there is no interior painting or staining required in the home. And, the exterior frame remains in the home thereby saving the trees and cutting down on the carbon footprint of the project.

We provide expert consultation on Weather Shield, Marvin and Pella window product brands. We will help you find the window that best fits your needs.

We're a proud distributor and installer of Weather Shield and other high quality windows & doors.
