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.

5/5
Before selecting the window source to replace all of the windows in our townhome, we spoke with three other competitors. They were each professional and provided great information about their products and had very knowledgeable reps. After speaking with Colin, we knew the right choice for us was The Window Source. He explained in detail the process, the benefits of how these windows, and answered questions that we had not even thought about. With the final price in hand, we reached out and conf... Read more

5/5
I would absolutely recommend The Window Source of Houston to anyone. From quoting process to order entry the team was always willing to answer my (many) questions. Jairo was our salesperson and he was wonderful to work with and highly communicative. I also really appreciated that they have their own team of installers rather than subbing out install to an unknown and possibly unskilled crew. Install went very very well, they covered all of our furniture and picked up all the broken glass, the te... Read more
