"We shopped around and selected Cornerstone to do our entire house (siding, windows, shutters, garage and front doors) not because they were the cheapest, but we were impressed with the quality of their products and felt comfortable with them. Also, their crew was very nice and did the little "extra" that are often over looked. Cornerstone did us right and we will recommend them to friends."

“The staff at Cornerstone is always polite and helpful. The installers were prepared to answer any questions that I have and cleaned up all of the debris so everything looked good when they left. This is the third time that Cornerstone has done work for me, and I will continue to recommend Cornerstone Home Improvement to my friends and family. I LOVE my new windows, soffit, fascia and guttering.”

“Frank and I had some windows replaced and we like them so much that we replaced more. Now the whole world looks cleaner! Our new replacement windows are a far cry from our old windows with their heavy storms, and new double pane windows are much warmer also. The installers from Cornerstone were very professional, efficient, and knew what they were doing. I would recommend them to anyone.”
Frank and Ruth J.

“I had done some research on replacement windows and siding before I called Brenda, from Cornerstone Home Improvement out to the house. We had a great discussion about window and siding choices and she ‘led me down the right street’ of which windows to buy. I knew that I made the right decision to replace my windows when winter hit. I could sit in my kitchen and remain warm. I would recommend Brenda and the Cornerstone Home Improvement team 1000 percent to anyone.”

The job site was kept clean, the work was finished in a timely manner and the windows and siding were a great value for my money.

Jan S.
Independence, MO
“My husband and I were very pleased with Cornerstone. We had several companies come out to discuss options and we felt that Cornerstone’s sales rep. was excellent and very knowledgeable. Their pricing was not the cheapest, or the most expensive, but we felt best about doing business with them. One of the things that set them apart from their competitors was that Cornerstone offers a lifetime warranty on their installation. Nobody else offered that. They finished the job in five days, completely cleaned up all of the construction mess and were just ‘great people.’”
