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.

Edwin and his crew showed up on time advised me about their process and began to work. They worked all day and finished up. They had covered everything in their way and cleaned up so no signs of work had been done. The windows look great. Thanks Edwin and crew. Well done.👍👍👍

Courtenai Leverton, I don't show we ever quoted or even sent you any communications. This is not something we do especially that late at night. Our office closes at 6:00pm. Please call our office and ask for me as I would love to figure out what's going on with this. Regards, David Mallette Owner 281-547-6900

Marty — review for The Window Source of Houston
The Installation crew did a great job. We needed a new front door and had to replace two windows. We are very happy with the results. It was 60 days from the initial phone call to the installation.
