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.

Betsy — review for The Window Source of Houston
Window Source of Houston is amazing! Veteran owned. Show up on time, each tech had their own specialty and all three of them were in sync doing the best work.

Stephanie Vera — review for The Window Source of Houston
Worry- free experience with Window Source. From the moment I choose their company the whole team made me feel at ease with the unique situation I had with my barndominium home. Communication was easy, I received a fast scheduled quote. And they installed my windows the week they arrived from the manufacturer. The team came out to address any concern. Thank you🙌

Fayette Acres — review for The Window Source of Houston
Process from initial meeting with the sales rep through installation and a subsequent order for additional windows was very smooth and professional by all Window Source staff, office and installers. MI windows are great looking and block sound. Very pleased.
