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.

Ned Barnett — review for The Window Source of Houston
The Window Source installed several doors and windows in my house. I can't say enough about the quality of their work as well as their professionalism. It was a very difficult job.

David Johnston — review for The Window Source of Houston
David and his team were very professional and provided a good quality product. Through the installation process I had questions regarding acquiring my windstorm certificate. David, the owner, personally got involved and made sure I received the window storm certificate. I would highly recommend Window Source for any future window replacement.

Soraya T — review for The Window Source of Houston
The Window Source of Houston (WSOH) is absolutely wonderful! We highly, highly recommend them. They offer solid, old-fashioned customer service. They bent over backwards to meet all our needs, and they pulled out all the stops for us, even though our job was a very small one. Everyone was so nice. From sales to financing to installation. All the way down the line. David, the owner, has a fine, fine company. We love our new NT windows. They are beautiful but, more importantly, they are hig... Read more

Cheryl Horn — review for The Window Source of Houston
Window Source installed 16 windows in our two story home. Patrick was our no-nonsense, no-pressure salesman. We really appreciated the time he spent with us, answering our questions and explaining all aspects of the job. Luis and his crew did the installation. They are punctual, knowledgeable and professional. They did a fantastic job on everything. The quality of their work is top notch. They left every area cleaner than what it was! We are very pleased with our purchase. The new windows are of... Read more
