About Us

Skip the middleman and come straight to the source, The Window source!

The Window Source of Houston is local veteran owned and family operated. We provide and install custom-made new construction or replacement windows in a variety of styles and materials, including vinyl, fiberglass, and aluminum. We also offer a great selection of exterior front doors, patio doors and sliding patio doors. We are not afraid for a little construction to modify your windows or doors to bring you vision to reality. Our Company core values are Honor, Courage and Commitment. Each one of these values describes the way our company operates within our community and it’s what sets us apart from other window companies that have their bottom line at heart, not your right to a fair deal. Best combination of service, selection and value.

Claudia Renteria — review for The Window Source of Houston
The Window Source of Houston is a great company to work with. I've had a positive experience thus far. From start to finish they have been professional and responsive. My installer Christian and his crew were great. They answered all my questions and even went further by explaining the process. I've only had my windows for a week now but so far I am loving them.

Steph K — review for The Window Source of Houston
The most Professional company I've ever worked with. Hailey the office coordinator and Preston, the Sales/technician walked us throughout the whole process. When we got the windows installed, they cleaned, and left my home like brand new. The windows are such great quality and keep the heat out of the house. They did such a great job from customer service to installation and following up. Reasonable price too. Quality windows.

Best price and shorter wait time than others promised. After four months (two with AC) noticed a drop in electricity bills by replacing eight windows across the east side of the house.

Julienne Burton — review for The Window Source of Houston
My entire experience with The Window Source was outstanding. Everyone was so professional and Christian’s crew did a great job on the replacement of all windows in my house. One of the guys even adjusted two exterior doors for me. I highly recommend this company to anyone looking to replace windows.
