The Window Source of Houston

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.

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!

Why I’m Impressed: Attention to Detail: They didn't just do the "big" jobs; they took care of the corners and edges that most people overlook. The clarity is actually startling.

My experience with The Window Source was great. The salesman demonstrated the effectiveness of their windows and worked with me to come up with a price within my budget.

We replaced 13 windows through Window Source. There were a few minor issues with the windows but all were resolved to our satisfaction. After much comparisons, Window Source had the best price. They were easy to work with and would recommend them to my friends. They also did a good job of cleaning up.

Matt M. and his entire team can be trusted to provide an honest estimate and will follow through to ensure the client’s satisfaction. We’re very i... Read more
