Bay Windows: You Dream It, We Build It

I had 17 windows replaced and it was totally painless. They were polite, professional, worked quickly, and were reasonably priced. They also did a great job cleaning up after themselves. I am planning to contract them again for future work on the house.

We recently had our windows and siding replaced, and we couldn’t be happier with the results. From start to finish, Heather (Owner) and Tom (Project Manager) were professional, responsive, and easy to work with. The workmanship is excellent—everything was installed with great attention to detail, and the final result has completely transformed the look of our home. The crew showed up on time, kept the work area clean, and clearly took pride in their work. We would absolutely recommend them to anyone considering window or siding work.

So glad we worked with a local company. Very professional and we are very happy with our new windows. Would highly recommend them.

Had windows installed on 10/14/25, they arrived at the time they said. Had all windows replaced they did a very good job,and cleaned up after finishing. Would use them again very good job.

I recently hired Window & Doors By Design for a major remodeling project in my home including window replacement, door replacement, gutters and siding and I couldn't be happier with the results! From the initial consultation with the owner Heather Sumrow to the final walkthrough, the team was incredibly professional and attentive to my needs.The design suggestions they provided were both creative and practical, perfectly aligning with my vision. They kept me informed throughout the entire process, ensuring there were no surprises. The workmanship was top-notch, and the attention to detail truly set them apart.If you're looking for a reliable and skilled remodeling company, I highly recommend Window & Doors By Design.

I cannot emphasize enough how much I would DEFINITELY RECOMMEND G&S contracting!! George is the main owner and founder and he works with his son. He came out personally to assess my windows in South Charlotte (he came down from Mooresville). I spoke with him and a couple others on the phone as well and everyone at this family-run business is prompt and professional. I was kept up to date on things in terms of when the windows would arrive, when they could be installed, etc. The man that actually installed my 10 windows is an employee of G &S that services my area. I think his name is Flavio and he, too, was phenomenal. He arrived on time, was neat and organized, and cleaned up after himself in and outside of my home. He was also friendly, courteous, and did a superb job...AND he completed everything in just 2- 1/2 days. So he wasn't wasting time and goofing off, he was putting in a full day's work. And the icing on the cake is that their pricing was the best that I found for a quality product. I wish every business conducted themselves with the integrity that G &S does!

3/23/23 G&S Contracting installed our 5,south facing, custom ordered windows made by Sunrise brand with solar package.They were all great to deal with. The installer did a very good, nice neat job in a short time. The windows are such an improvement, keeping cold and heat out. Keeping cool air or heated air in. Our house is now more comfortable in every room at any time.We will use G & S again! We strongly recommend them and Sunrise windows.

We had all of our windows replaced with G&S. Reasonably priced, quick install, great communication, and wonderful customer service. George was a pleasure to work with and Flavio did an amazing job on the install. Highly recommend!!

We have done business with G&S for over 20 years. Over those years they provided window replacements, front entry door replacement, screened in porch, sliding glass door, and storm door replacement. All work was professionally done and we have been very satisfied with the products. Now after all these years we have had some product lifetime warranty claims and George has always responded to assist us in these product warranty claims. Thanks. It’s been a pleasure doing business with G&S.

Just spoke to a man on the phone- he could not repair my problem- but was more than happy to get me in touch with someone that could! I will be calling them back if I need- or passing along the number to anyone I know needing- doors or windows. I appreciate the customer service even for a non customer.

I would like to highly recommend G&S Contracting, inc. to anyone who is looking to install new windows. We had new windows installed in our home last month. G&S was able to start the project a day earlier because they finished a prior job before expected. They were able to begin the process late one afternoon and then finish up early the next morning. This kept me from having to miss a day a work, which was much appreciated. They did a great job and we love our new windows. We also found their pricing to be very reasonable when compared to other companies. Thank you, G&S! We will definitely consider using your services again!Israel Grigg, Mooresville, NC
