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.

Gary — review for The Window Source of Houston
4/5
After getting quotes from five companies, we chose The Window Source to replace 36 windows. We signed the contract June 25 and were told installation would take approximately six weeks. Installation began August 11. On the first day, we discovered that three picture windows had been delivered as single-hung windows. The following day, after getting a closer look at the windows installed on the front of our house, I realized they were black rather than the bronze we had ordered. The next mornin... Read more

Thank you for taking the time to share such a detailed and honest account of your experience. While I'm pleased to hear that you love your new windows and were happy with Luis and his installation crew, I sincerely apologize for the frustrations you experienced along the way. There is no question that we fell short of the experience we strive to provide. The original ordering mistake, the delays in getting the replacement windows, and especially the lack of consistent communication placed an unnecessary burden on you and your family. Regardless of how the mistakes occurred, it was our responsibility to manage the situation better and keep you informed. You should never have had to repeatedly contact us for updates. I also appreciate your understanding regarding some of the circumstances surrounding our project manager's recovery. However, that does not change our responsibility to you as our customer. I'm glad we were able to get the correct bronze windows installed, and I appreciate you recognizing Luis and his crew for their workmanship, professionalism, and attention to detail. I'll be sure to share your compliments with them. I also wanted to personally follow through on the additional dog boarding expense. I felt it was only right that we cover that cost since our mistake and subsequent scheduling changes caused the additional expense. I'm glad I was able to deliver that reimbursement to you. We still have the remaining sash window and screen replacements to take care of, and we will see that through until everything is right. Earning your confidence back is important to me, and I don't take your willingness to recommend us or use us again lightly. Thank you again for your patience, your honesty, and the opportunity to make things right. We appreciate your business. David Mallette Owner, The Window Source of Houston

We were replacing 20 windows of various shapes and sizes and Andy offered great suggestions which turned out to be the right choices! We were contacted throughout the entire process advising us of when the windows were expe... Read more

A small repair but Luis went beyond the one window and put a new aluminum strip on another window. Plus his crew inspected all other windows and re-caulked everything. Five stars for warranty service 4 years after install

Our commitment doesn't end when the installation is complete. We stand behind our products and workmanship and believe great customer service includes being there long after the sale.

5/5
I spent considerable time researching window companies, and I had several companies come to my home to provide demonstrations and estimates. In the end, I chose neither the cheapest nor the most expensive option—I chose The Window Source of Houston. First, it's a Veteran-owned business. I always try to use fellow Veterans, anytime I possibly can. The sales representative, Jairo, was excellent. I immediately felt comfortable and confident with both him and the company. They offered the best wa... Read more

Thank you for taking the time to share such a thoughtful and detailed review. It means a great deal to our entire team, and especially to me personally. First, thank you for your service and for choosing to support a fellow Veteran-owned business. We never take that trust for granted. I'm also glad Jairo made such a positive first impression and helped you feel comfortable with your decision. With more than 30 replacement windows installed, we understand the importance of getting every detail right. While manufacturing defects and occasional installation-related issues can happen, how a company responds when something isn't right is what truly matters. We believe standing behind our products, honoring our warranty, and making things right without putting pressure on our customers is simply how business should be done. Your comments about our honesty, straightforward approach, warranty, and follow-through are exactly what we strive for at The Window Source of Houston. Our relationship with our customers doesn't end when the installation is complete. Thank you again for your recommendation and for trusting us with your home. We sincerely appreciate your business and wish you all the best! David Mallette Owner, The Window Source of Houston
