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.

Cassie Revia — review for The Window Source of Houston
The entire experience was top-notch. Very quick response when I sent my first inquiry. The team arrives on time, installed new windows flawlessly, and make sure everything was spotless before they left. They even hauled away all the old windows and debris, which we really appreciated.

Maria Barrington — review for The Window Source of Houston
Window Source crew and sales team did an amazing job. We love the new windows. We researched different companies and happy we decided to go with you all. Having good windows makes a difference in your heating & cooling bill. Think about it, where do you lose heat & cool air from? Your windows & doors!!! New windows look so nice on our house.
