Great company to work with! We felt more than comfortable with our sales rep as he explained our window options. Our windows were installed a week earlier than expected by such a clean, professional crew. I would definitely recommend Window World of Joliet!
Debra Lewis (June 2024, Romeoville)
The team was prompt and ready to work when they arrived at my home. I had two doors and a window installed. I highly recommend Window World of Joliet for windows and doors. I’ll be using their team when it’s time to replace my siding!

I rarely write reviews, but had to for Window World of Joliet. Their service and products are top-notch. They were fast, professional and answered all my questions patiently. Despite replacing most of my windows in the cold winter, they worked efficiently one room at a time so we barely felt the cold. The new windows look great, operate smoothly and are draft-free. Plus, their prices were significantly lower than other quotes. Highly recommend Window World!
