See Why Clayton Residents Love Window World

Window World did the install today of 15 windows in our 38-year-old home. As I expected, they did a GREAT JOB with extreme attention to detail and even cleaned up afterwards. The windows are beautiful and extremely easy to clean. The entire process from the first meeting with the salesman to final install was easy, pleasant and with no surprises. I highly recommend Window World if you need windows.

Window World took great care of us. The installer was wonderful and showed us how to properly use the windows. He took the time to show us the different trim and was very friendly. The guy who sold us the windows was very informative and not pushy. The windows are beautiful. Thank you to the team at Window World. Best deal we found.

Window World St. Louis transformed my screened porch into a 3-season room by replacing screens with new windows. They totally improved the look of the room and did an excellent job. Workers were all great and easy to work with. My satisfaction was top priority. The price was great, and with the financing options, it helped me get my job completed on my timeline. Highly recommend!
