"The Chicago Window Guys is a great company to have install your windows and doors. the owner Russ came out and was not aggressive or pushy like other companies. He was patient and truly listened to what me needs were. Since I have a big home I wasn't able to have all my windows done at once. This was ok! Russ worked with my budget and I got a new patio door, kitchen window and living room window. I was concerned about how well they will block out noise since I live close to a train track. The door and windows are great at reducing noise and keeping my home cool in the summer and warm in the winter. The installers were professional and did a great, high quality and thorough job. Will use this company again to get the rest of my windows done."

"I have been rehabing my moms home to sell and thing have been REALLY stressful. I had two windows that were cracked that I have been looking to get fixed for more than two months. I have had several window companies tell me it was “impossible’ to replace glass panes in thermo sealed windows. I was quoted $10k for one window replacement 😬 Jon showed up like a miracle! He was extremely responsive to my initial inquiry, was onsite promptly to assess the two cracked windows and noticed another window that had a broken seal. He provided a reasonable repair estimate for the three windows and was back to complete the work within three business days! Jon was a lifesaver, his responsiveness allowed me to get the house listed yesterday ! I am SO grateful for Jon!!! If you have windows that are cracked, call Jon to get them repaired!!!"
