Get matched with top window pros in Winthrop Harbor, IL

"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 love working with Chicago window guys- the owner is very easy to talk to and straight forward. The price that is presented is a fair price and it is the price from the start, there is none of the sales tactics, like the “sales” or “discounts” that other companies try to sell you on. The wait time for window production is reasonable and the installation is efficient. The first time we had windows replaced there was a miscommunication but the installers fixed it on the spot, no problems. The owner also allows you to buy and replace windows at your own pace, which is very accommodating since windows are expensive. Plus the windows look great! We will continue to use them in the future!"

"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!"

"Completely happy with the excellent work installing my new windows. I would highly recommend window solutions ."

"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!!!"

"A very thorough job of installation of the windows. The windows look, and feel MUCH better than Our old windows."

"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."

"The day we talked to NIW, someone came out to give us an estimate. I hired them on the spot, and they did the work within a day or two. Very respectful of our home and belongings, fine job on the windows!"

"Mark did a great job. Windows turned out great"

"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!"
