"From beginning to end this was a complete good experience. John came out and showed us the window and explained the process. After doing my research I have found the windows he uses to be excellent quality. Ordered the windows, 12 weeks to the date they were installed. The install was done in half a day. They team was very clean, helpful and complete. They answered all my questions and even let me watch! We noticed a difference within hours of sealing up the windows how cool my second story remained with the Energy Efficient windows in. I cleaned all of them with an easy process of sliding the clips and opening them. What a dream window and only wished we had done this ten years earlier. The windows were 29 years old, solid wood and clad. From the outside you can hardly tell the difference. These were a great purchase, and we are looking forward to having the other 13 windows done with Best Windows."

"We had to replace 3 windows and a huge patio door. The replacements were smooth and we love how easy they are to open/close. We can already feel the difference with our new patio door, and have a nice cozy family room now! Russ was incredibly helpful and accommodating with our timelines. The staff has always been friendly and quick to respond to us. We definitely recommend Chicago Window Guys!"

"Excellent. Kevin figured out the problem with the sliding patio door quickly considering you couldn't visually see the Christmas Decoration that somehow got trapped under the sliding door. He also fixed a crooked sliding closet door and rubber weatherstripping on an interior garage door. He was fantastic and will use him again. No doubt!"

"Very efficient! Came on time. Returned with finished cover as promised. Great advice as to maintaining upkeep of window as also the well. Thank you!"
