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
I don't usually take the time to write reviews, but my experience with iWindow was so seamless that I felt compelled to share. From start to finish, the entire process was a masterclass in efficiency and professional standards. 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. Modern Approach: It’s refreshing to work with a company that uses updated tech and streamlin... Read more

5/5
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. The installation crew was amazing. Covered everything inside, took down window coverings and replaced when finished. Insisted on sweeping up the little bit of mess on floor and outside looked the same as before, except better with the new windows! I absolutely love them!

5/5
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.

The window installation project is now complete, and I couldn’t be happier with the results. The difference compared to our prior experience is night and day. The workmanship is clearly top-notch, and the installers worked hard all day with excellent attention to detail. The company exhibited a fantastic level of service throughout the entire process. 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
