I had an excellent experience with SM Windows. Right from the fellow who came out to give me a price to the one who made the final measurements and the installers, it was a great team. They were quick and efficient while doing the install. The finished product looks great! I would definitely recommend them for windows.

As a Real Estate Broker, I’ve worked with many contractors, and Alex at SM Windows is truly a standout. He is a fantastic communicator who consistently delivers quotes on time, making the process seamless for both me and my clients. Many of my clients have shared wonderful feedback about their experience with him.
Josh West
Working with the team at SM Windows & Doors made what, for me, was a big project, very easy. Good communication from the first consultation with Alex through the last moment of the installation. The install team was on time, well organized, extremely professional and left the work site each day immaculate. They kept us informed each step of the way. Looking forward to the benefits of our new windows.
Heather Reilly
We’ve been trying to get a window replaced from different companies for two years without success. Contacted SM Windows and Doors and in no time we had someone in to measure and give an estimate. Once approval was given, window was ordered and installed with great professionalism. The installers were quite knowledgeable and friendly. Extremely pleased with the final product. 👍🏻👍🏻👍🏻👍🏻👍🏻
Reggie Audy
From the estimate to the installation, the whole experience was above and beyond. The windows are perfect. The installation is clean. The customer service was next level. Alex was beyond helpful. He really put my mind at ease. I couldn't have asked for a better experience. As a person with a lot of responsibilities and a tight budget, I highly recommend SM Windows and Doors.
