Dennis was patient as he answered all my questions through the decision-making process. The installers took great care as they removed the 30+ year old windows and replaced them with new ones. The cleanup was amazing as you would never had known they were there except by looking at the beautiful new windows. The office staff was friendly and went above and beyond with the way they handled things. I will be using them again and highly recommend them for a local, family-owned business who takes pride in their work, are reliable and care about the customer. I was highly impressed with the whole experience. Thank you Cornerstone for a job well done! - 5/5 — Anonymous The crew was so great to work with and they did a wonderful job installing our windows. Each installer introduced himself and assisted us with our blinds during window installation which we so appreciated. Love our new windows and highly recommend them. We will definitely use them for future projects. - 5/5 — Anonymous We moved into our house last year. The basement French doors had gaps so big you could see outside. With the winters here, the space was unusable. We knew we needed to replace them before another winter. I reviewed multiple companies and decided on Cornerstone. The process from sale to install was easy, professional and quick. The installers took their time to ensure the fit was perfect. These doors are beautiful and now my basement is one of the warmest parts of the house. I will definitely be using them again! - 5/5 — Anonymous We worked with Cornerstone to replace eight windows in our home. They were upfront, had clear communication and were easy to work with at every stage of the process. The installation team they had complete the work were also friendly, efficient and did a great job. I recommend working with Me'Shelle and her team! - 5/5 — Anonymous Working with Cornerstone was great! We had an exterior door replaced and a sales rep came out and showed all the options and walked us through pros and cons to each and provided recommendations along the way. The time estimate for installation was spot on! The actual installation was great! The door looks exactly how it was pictured. Additionally, they installed interior trim which we already had purchased and was going to install ourselves. That was a great perk and one less thing for us to worry about! Greatly appreciate their hard work, communication, and expert knowledge. ## FAQ **Q: What areas does Cornerstone Home Improvements serve for window and door installation in Kansas City?** A: Cornerstone Home Improvements serves Kansas City, MO, and surrounding areas for professional window, door, and siding installations.
