We had windows put in last summer. The team that put them in were awesome and professional. The windows are great quality and easy to use. Last week, a branch fell and tore one of the screens. Cornerstone had a guy out here quickly to replace the screen. I cant say enough good things!

Just had new windows installed in my home by Cornerstone. The quality of the windows was excellent, but the quality of the installation was even better. The guys who did the work were very professional and friendly as well. The windows look great, and I can already tell a difference in the quietness of my home as well as the fact that there is no draftiness in my home as there was with the old windows. I also felt the price was quite reasonable after having received quotes from two other companies.

We just had a couple thermal windows replaced that Cornerstone had installed about 20 years ago. The only reason we had them replaced was because we wanted to change the style. From the salesman to the office to the installers...everyone was great to work with! The installers even laid down tarps over the carpet where they were going to have to walk and under the window openings. They did a wonderful job cleaning up everything after completing the installation. Cornerstone also installed the siding on our house several years ago.

I'm very happy with Cornerstone! They installed three new windows and I suspect that I'll have them back to replace more! The estimate was unrushed, thorough and competitively priced (plus I got a discount which is always nice). The installation was a very smooth and professional operation, too. The windows---fabulous. It's quieter in the house now and I am looking forward to no longer having to bundle up during the cold winter months! Highly recommend.

We had an awesome experience with Cornerstone replacing our old windows. our place has lovely woodwork from the 1930s, so I was worried about how the new windows would look and they turned out great. The salesperson, Dennis, was knowledgeable and low pressure - he answered all questions and came out twice to discuss without a guarantee of sale. They did the job in 1.5 days and left the place as they found it. The crew was efficient and personable. Our neighbors were so impressed watching them work that they called them out for an estimate on some work. We highly recommend Cornerstone!

We replaced 30 + windows with Cornerstone recently. The entire process was positive! The estimator, office staff, and 3 gentleman that did the installation were all professional and easy to work with. We would definitely recommend them!

ALL staff were pleasant and courteous. My 100 questions were answered without hesitation. The men who did the install set right to work and were quiet and cleaned up after the work. They left behind beautiful , clean, easy to open and close, non leaking window! I would recommend this company to my friends. The other great thing is that you can buy as many windows as you can afford and they don't make you feel like you should buy more than you can afford or need. There is no pressure.
