"I had a foundation issue that caused a window to shift out of its casing. Window World was happy enough to help me with just the one window that would need to be replaced. The sale, scheduling to the installation was done very quickly and everyone was all very polite and professional."

"After the first team wasn't able to repair the windows, Star Windows sent a second team that included the Window Whisperer who worked on the windows until they both worked as intended. I am very impressed with this company and their level of service. Most window companies just want to replace windows, not even attempt to repair, but not Star Windows! I would highly recommend this company."

"Very prompt and priced competitively to the major egress window installer in the Kansas City area. They provided a fair and prompt quote, showed up when they said they would and finished the job on time. They also come back a week after the install to add dirt around the egress window outlet after it has settled. I've recommended them and would hire them again."

"Highly recommend this company for windows. Had all windows in the house replaced with good quality energy efficient windows at an unbeatable price. Install crew was fantastic, and customer service is best I have ever had, after getting some caulk on one of our new screens, they ordered a replacement for us without having to ask them to. We had a quote from another company for windows with same energy ratings and similar construction but they wanted 3x the money for the job. Don't look any further than NuSash for your replacement windows."

"I am so happy with the work that Cornerstone did on our windows. After dealing with several lengthy, high-pressure sales pitches from other companies, Derrick from Cornerstone was a breath of fresh air. He came out in May and was able to quickly give me multiple options for the best products for my house. I appreciated that he did not try to upsell me, while still showing me high-quality products to choose from. The windows came in early July, but I had to postpone the installation until 7/27, and Cornerstone was so flexible about the schedule. The crew showed up promptly and worked efficiently without cutting corners, they were friendly, and they did a great job cleaning up after. We noticed an immediate difference in the temperature and comfort of our home as soon as they were done. I was also impressed that one of the owners called me the following Monday to make sure we were satisfied. We received stellar customer service, high quality work, and an excellent finished product from Cornerstone. I would highly recommend them for any window replacement project!"

"There were a couple concerns when the project was first completed. I called the company and the owner came on a Saturday to resolve the issue. He even took out of pocket to purchase a few items. He took time to explain what he was doing and finished the project superbly. I m completely satisfied"

"Seth was very prompt and did a great job. I had a loose threshold and he fixed it."

"I thought it went well. The blinds turned out very pretty. They were prompt and professional."

"The customer service from choosing the window treatments to having them installed was excellent. The communication was always prompt and professional. We would definitely recommend their services."

"It went well. Within a hour we were in position to repair or replace garage door."
