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.

Customer Reviews

John — review for The Window Source of Houston
Luis and his crew were great! They replaced 33 windows. Was very impressed with their workmanship and how there was no wasted movement. Perfection. They even installed windows on the second floor working off a metal roof.

Teresa Houston — review for The Window Source of Houston
I highly recommend Window Source of Houston. I had four very large windows replaced and the process went so smoothly. From the initial appointment, measurement of windows, and installation I could not be more pleased. Will definitely use again and have recommended to my friends.

Joe Madison — review for The Window Source of Houston
Luis and his crew were on time (actually a little early), had exactly our order correct, knew where the specialty window was supposed to be installed along with the rest of them, was professional, clean, took every scrap of the old windows with them and finished an hour and 20 minutes early. I wish every contractor experience was like this, the only problem is now I've got to keep my backyard clean because these windows are big and beautiful. EXCELLENT!
