Steve Park — review for The Window Source of Houston
I had 5 windows replaced at a condo in Galveston. The windows are great, the installation crew was fantastic, on time, very neat and completed the job quickly. I would definitely recommend them.

Marian Gibson — review for The Window Source of Houston
Our experience from sales to installation was fantastic. Sales - excellent Windows - MAGNIFICENT Installation - Absolutely PHENOMENAL. Luis Roldan and his crew were the best we have ever had at our home. (We have flooded twice, with multiple crews in our home.) Best ever experience with contractors, wouldn't hesitate to ask for him again, should we decide to put new windows in garage. They worked nonstop, answered any and all questions we had. During the final walk around, there was nothing... Read more

Thank you so much for the incredible review and for trusting The Window Source of Houston with your home. Hearing that your experience from the initial sales consultation all the way through installation was fantastic truly means a lot to our entire team. Luis Roldan and his crew take a tremendous amount of pride in their work, and I’m glad to hear they delivered the kind of professional window installation experience we strive for on every window replacement project in Houston. We believe homeowners deserve not only high-quality, energy-efficient windows, but also a clean, professional installation and clear communication throughout the process. I especially appreciate you pointing out the final walkthrough and attention to detail. Making sure every window functions perfectly and that homeowners know how to use and maintain them is something we take very seriously. And I’ll definitely pass along the compliment about Luis’s caulking skills — that’s a new one, but I know he’ll be proud of it! Thank you again for recommending us. If you ever decide to replace the windows in your garage or anywhere else in the future, we would be honored to help again. — David Mallette Owner, The Window Source of Houston

Heidi Scott — review for The Window Source of Houston
I used The Window Source to replace 2 windows on the front of my house that had failed gas seals. I was not given a hard sell or pushed to replace all my windows. I provided pictures and approximate dimensions and they gave me a quote to match the windows to the existing ones. After agreeing to the price, they sent an expert to do exact measurements and ordered the windows. The delivery time was longer than expected but the Thanksgiving and year end holidays I’m sure had something to do wit... Read more

Thank you so much for taking the time to share your experience and for trusting The Window Source of Houston with your home. One thing we truly believe is that homeowners should never feel pressured into replacing more windows than they actually need. Whether it’s two windows or a full home window replacement in Houston, our goal is simply to provide the right solution with honest pricing and no high-pressure sales tactics. I’m glad the process worked smoothly for you—from the initial quote using photos and measurements to the final professional installation. Our team works hard to protect every customer’s home during installation and leave everything clean so the only thing you notice afterward is your new, clear, energy-efficient windows. You also made a great point about failed window seals. Many homeowners don’t realize how much clarity and insulation they’ve lost until they see the difference with properly sealed replacement windows. We really appreciate you trusting us with your project, even if it was just two windows. If you ever decide to replace more windows in the future, our team at The Window Source of Houston would be honored to help again. — David Mallette Owner, The Window Source of Houston
