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
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!
Marcus Kidd
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!
Nava Malahimov
Window World is an amazing company with great customer service. The installation team was incredibly clean, efficient and hardworking—leaving my house spotless! They installed around 20 windows, including a sliding door and bay window, in just two days. The quality of the windows and doors is outstanding! Overall, I had a fantastic experience.
Julia Kulik
I chose Window World of Joliet to replace our 29-year-old slider door, and the experience was outstanding. Zack provided thorough information and demonstrated professionalism, courtesy and expertise. The installation team expertly managed issues with the old opening, resulting in a secure, high-quality door. I highly recommend Window World of Joliet for their exceptional service!
