"Representative came to our house. Inspected and measured windows. He informed us of the various options. Very friendly and professional. We didn't feel rushed or pushed to make a decision. Half of the cost was expected at the time of the order. We had to wait over a month for the installation but were told that up front. Installation was done in that promised time frame. Day of installation, the worker explained what they would do and answered all questions. They were done in less than 2 hours which included a very good cleaning of the installation area and windows. I immediately noticed less noise and draft from the new windows. We were very pleased with the windows and the work."

"Got a quote for a couple of residential window repairs needed in about 10 minutes and they were out to fix them within 5 days. Great experience and will definitely look to them in the future for any window repair needs."

"Seth was excellent at repairing a set of exterior french doors that had plagued us since we bought the house, installing weatherstripping and repairing a broken Andersen window sash. It's evident he takes pride in his work and I would absolutely work with him again!"

"My words won’t do this company justice. Hire them and experience it yourself. We literally had our egress window installed yesterday and can’t even see any inside mess. Their entire crew is friendly and social. Curtis was willing to spend extra time with my wife and I talking about basement finishing without any obligation. I see this company as the Maserati of home repair companies.... 100% top notch."

"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!"

"Wonderful job replacing two basement windows. They went above and beyond when wood rot was discovered and also repaired this issue. Reasonably priced and knowledgeable installers. 5 Stars!!"

"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."

"The men were professional, careful, cleaned up their mess and even avoided the new plants peaking out of the ground. The windows are so pretty, A very nice improvement on our home."
