"Chicago Window Guys provided me with 8 replacement windows in my condo unit. The windows were fitted very well, and they were able to remove my old windows and install my new windows in a very timely manner. In addition, they were able to replace windows on the fourth floor of my building, while many other companies I contacted were not willing or able to do so! The warranty they provide with their windows also provides great peace of mind."

"Gus and his team at EcoChamp Windows & Siding are amazing! They were very professional, responsive, and installed high quality windows in our home at competitive pricing. I love my new windows and Gus’ suggestions really made a difference. My husband and I highly recommend this company!!!"

"Howard showed up at appointed time and looked over the widows I wanted replaced and told me about his windows and showed some samples of the quality. His prices were very good and he sent his instaler out that week to get accurate measure of the windows to be replaced. I had the new windows installed within 2 weeks in time to get the federal tax credidt. The windows look great and really make a difference in my heat bill."

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

"Repaired my compartment windows in a very reasonable account of time. It turned out my windows were "obsolete", but they were able to find parts and repair the window within the quoted price anyway. Very much appreciate their attention to service."

"My daughterâ s room window would not close at the beginning of the cold season, and technicians were onsite on the same day to deal with the urgent issue, examined other windows that has issues, provided a very competitive estimate and completed additional repairs a couple weeks later. I will be calling them again for any window repairs in the future and highly recommend to anyone in need of quality and honest team of professionals."

"He did an excellent job with repairing my window frame."

"I recently had my window seal failures repaired, and the difference is night and day. Before the repair, I was dealing with foggy glass, drafts, and noticeable temperature fluctuations—especially during colder days. It not only looked bad but also made my home less comfortable and likely less energy efficient. The repair process was smooth and professional from start to finish. The work itself was completed efficiently, and Jon took care to keep everything clean and protected during the process. Now, my windows are crystal clear again, and the insulation has noticeably improved. There are no more drafts, and the rooms feel more consistent in temperature. It honestly feels like an upgrade to the entire house. If you’re dealing with failed window seals, I’d definitely recommend getting them repaired sooner rather than later—it makes a bigger difference than you might expect."

"Dominik W. arrived early, took his time explaining everything he was looking at, and walked us through the entire process?from the window demo to the installation. He wasn?t pushy at all, and we ended up choosing to buy from them. If you need new windows, give Dom a call!"
