Get matched with top window pros in Winthrop Harbor, IL

"I am extremely happy with my new windows and patio doors. My house is warmer, no longer have drafts. High quality windows and doors. The installers were top-notch, did an amazing job. Highly recommend Chicago Windows Guys."

"I love my windows and siding. My house looks like it’s brand new. The windows and siding transformed my house. I would recommend Gus at EcoChamp Windows and Siding to all my friends and family. It looks amazing!"

"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."

"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!!!"

"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."

"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!"

"Very detail oriented. Prompt start, projects completed quickly and thorough clean up."

"Fabulous! Their attention to detail was superb and they added extra touches we hadn't asked for. There was a small 'punch list' after the job was completed, which they tended to within a week. The crew was excellent and the work was completed on time and on budget. They rewrapped windows from another installation to make sure everything matched. The job wasn't without its hiccups along the way, but the communication and follow through was excellent."
