Cornerstone is a Kansas City window company, entry door replacement company and vinyl siding installer. If you live in the Kansas City area, you may have noticed a trend. Big manufacturers want to sell you one replacement window, their window. They tell you why it's better, more energy efficient, made of the best materials, and tout all of their features.But how do you know if it's the best window for you? At Cornerstone, we approach it a little differently. We carry dozens of brands of windows (and doors and siding too) and we can tell you the advantages of every single brand from a non-biased viewpoint.

At Cornerstone, installation is our lifeblood. We started as an installation company over 40 years ago. For years we installed windows, doors & siding for the biggest companies in Kansas City.
