My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.

Featured Reviews for Window Installers in O Fallon

Zen Windows of St. Louis LLC
Window Installers in O Fallon
Average rating: 5 out of 5 starsJuly 2, 2025
“Zen Windows replaced our windows. The windows are custom made and excellent quality. From the start of the process till the end has been easy with great communication and professional installation. There was absolutely no sales pressure like with other well advertised window companies. The company answered all questions and gave exact quotes. The installers were professional, covered the floors, sink, and bathtub to protect them. Mr. Eddie and Mr. Darryl were friendly and experts with many years of experience.The windows are beautiful and open with ease. No complaints at all with this company. Please consider Zen Windows for your window needs.”

Average rating: 5 out of 5 starsJune 24, 2025
“I recently had replacement windows installed by Wilke, and I truly can’t say enough good things about the entire process. From the moment I placed the order to the final installation, everything was handled with care and professionalism. The ordering process was simple and clear. Payment was straightforward, and they communicated every step of the way so there were no surprises. The office staff was incredibly helpful, friendly, responsive, and always willing to answer questions or provide updates. It made the process seamless. The installation team showed up on time, worked efficiently, and treated my home with respect. They were professional, knowledgeable, and easy to work with. They take pride in their work, and the results speak for themselves, the windows look fantastic. Overall, Wilke exceeded my expectations, and I would recommend them over and over again. It’s rare to find a company that delivers great products and outstanding customer service, but Wilke does just that.”

“Replaced an exterior door. The door was special order because of its size. It took about a week to get the door in and the installation was set up promptly after. The technician arrived on time and worked diligently. The door looks great. I would recommend and also use again.”
