Cornerstone Home Improvement, Inc.

Have used Cornerstone for all my exterior entry doors as well as a total low e window replacements. They are extremely friendly and total pros . We have had multiple contractors over a period of last two yrs and I can honestly say this company was far above anyone else we used during our remodeling period.

The employees at Cornerstone Home Improvements were extremely professional and came to my home and did the bid for free. There was no pressure to make a decision. They thought about things I would not of thought to ask. The install went perfect no problems and their install team was extremely efficient, personable and the job done was more than perfect!. I love my new windows and doors. I would highly recommend this company!!!! Julie

They installed 3 large windows. I don’t give them a great rating because the screens will stay on. There is no clips or anything offered by them.

Cornerstone is the BEST company in KC for doors and windows! Their doors are super secure and extremely energy efficient! The screen doors have options to raise or lower the windows which is helpful if you have furry children that like to lean on the lower portion of the screen door. Their windows are exceptional in all aspects with regards to ease of use and energy efficiency. When one ended up cracking after years of use, they came out and had it repaired in a very short period of time. I can't stop talking about the service and quality of this company!

Finding a service provider through HomeAdvisor made getting our project completed in the most cost effective manner, and to our complete satisfaction. Cornerstone, themselves, made every effort to make sure the project was done correctly. They also offered the best warranty of all the companies we received estimates from. We have already started to plan a future project with them.

They were very knowledgeable, not pushy. Worked with my schedule. Installer was prompt and efficient.

I was very pleased with the overall experience from start to finish, I would and actually have recommended this company. I love my new windows!!!!

We had a great experience with Cornerstone. The salesman was very knowledgeable and the installers were efficient, did great work and cleaned up after themselves.

I am very impressed with the staff and the product. Everyone was professional, and did exactly what I needed. The installation crew even helped me jump start my car, and switched the screens to the pet-resistent screen. I am completely satisfied with th product and staff!!!!!

Fantastic, timely, friendly and got specialty window for me. Took a little while to get it ordered and put in but that was not their fault. Appreciated all that they did for me on getting the window I wanted.

They came for the appointment on time, explained the window completely and answered all of my quesitons, and I was okay with their proposed price.

It was excellent work.
