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.

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.
