St. Peters, Missouri Customer Reviews

  • I’ve used Window World 3x now and have referred my clients to them. They come out quick to get measurements and get your quote to you right away. Installation crews are extremely knowledgeable and friendly. I couldn’t ask for better service.

  • We had windows put in a couple years ago and they were very good about coming out and fixing anything that was wrong. When we decided to put siding on we had them quote a price and it was a very good price so we did it. Tuesday they started. They came early and left late every day. Their work and workers were the best we have ever had; they did such a great job and they cleaned up everything spotless when they were finished. I would recommend them to anyone getting siding and would gladly have people come by and see how great a job they did.

  • This was a very pleasant experience. We had all the windows in the house upgraded from the 1920’s to new double pane double hung for less than we budgeted. They were a dream to work with and the entire process was the easiest we have ever had with contractors. The energy savings is just now appearing on our budget sheet, and the money saved will be banked so we can travel to Europe next year to see the kids in their new house in Rotterdam.

  • Wow. I took bids and had people out from five leading replacement window firms. Window World was 1) The only on time appointment, 2) the lowest price, 3) listened to what I wanted, 4) didn’t try to “upscale me” and today they installed my eleven windows. They called when they said they would and they did a great job! I couldn’t be happier! I review Commercial Construction for a living, these gentleman were professional without being stuffy, polite (which is rarely seen) and truly a pleasure to have in my home. Thanks for a job well done!
