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.

Customer Testimonials

I got three bids, Window Source and another company were using the same windows product. Window Source's price was about 12% lower. The small team communicated well enough on the Covid impacted delivery. Day of install was a breeze, They were even nice to the dogs :) . One of the windows had a hairline crack, installers saw it, brought it to our attention, they scheduled the repair, couldn't have been easier.
