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.

Jairo our salesman was great, no high pressure sales technique. Daniel and his crew of installers showed up and wasted zero time getting to work. They were very professional and did an excellent install. Also they kept my house clean, it looked like they were never here. We are extremely pleased with our new windows have made our home look and how much cooler they keep our home.

September 2025. Excellent experience with discussing purchase of windows and glass sliding door. Clayton, David and Luis were of great assistance through the entire process. It is important to read carefully the details of any contract presented for signing. I would highly recommend Window Source.

This review is for all the great people that are part of Window Source. Clayton was our service rep and he was prompt, patient, and kind as we requested multiple quotes. Even when we approved the "final" quote- he made a suggestion to help us get us to the final final quote. Edwin and his team were simply phenomenal- I have never had a more respectful and professional team. I would enthusiastically recommend Window Source for your next window and outside door project!

If you need a company that offers amazing pricing and crews that work their butts off, then make sure you choose The Window Source of Houston. Had 36 windows put in and they did it all in 3 days!! Was a pleasure to work with!

Installation went very smoothly. The crew was careful, thorough, pleasant and cleaned up afterwards. We will use the Window Source for any replacements in the future.
