"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!!!"

"Siding and Windows Group is a top not h company and we highly recommend using them if you are looking for high quality and honest work. We were in a special situation and Angelo was with us from the moment I placed a call to the company, until we were ready to move forward. His approach was no nonsense, no pressure, and that is because they want to do place you within the right product categories and at the right budget. We started with just new James Hardie siding but decided to add a new front door and a new rear patio french door. Could not be happier with the design and color choices. There is a reason this company is top rated and has a long list of references which they provide so you can drive and see the work yourself."

"Window itself is beautiful and everything works as it should. The company was great to work with. I especially liked that I met with the owner and not some high pressure salesman. The installers were top notch. If it wasn't for the new window, I wouldn't even know anyone was here. They left everything spotless. The install went smoothly and everything was insulated and sealed so I have no worries about drafts or leakage. Thanks for such a great job. I highly recommend this company. Not only were they the best bargain for the money but their product is to notch."

"The team that came over to our house to fix our window was very nice, quick and did quality work. I would definitely use them again."

"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."

"Closed stuck windows. Now OK as long as these windows are not opened. Offered service to replace hardware on window for $150 per window. Decided not to do anything."

"Showed up as scheduled. Quickly replaced the thermal pane in my window . Price was reasonable."

"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."

"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."
