See What Our Happy Customers are Saying
“Great experience with Window Depot! 22 windows installed with expertise, and the ProVia windows are top quality. AC and heat runs maybe less than half compared to the failed windows that were 26 year old builder grade. Customer service was very professional, including one broken glass on delivery which they ordered immediately and replaced the sash in 2 weeks.”

“I had a great experience with window depot stl from start to finish. Joey initially came out and took the time to go over all the details with me.He was knowledgeable thorough and fantastic to work with. When it came time for installation Ryan and his crew did an amazing job. They were professional, efficient, and the quality of their work really shows. The entire process has been smooth and I couldn't be happier with the results. I highly recommend Windows depot to anyone looking for quality windows and excellent service. Thanks again”

“If I could give them 10 stars I would! From the first conversation with Joey, then to Ryan and his crew was absolutely top notch! The attention to detail, the care and respect for your home is second to none. When they came today to install windows in my home they laid down floor covers to protect our hardwood floors....how thoughtful! Extremely respectful of our home. Amazing job! Definitely recommend you to all my friends”
