Get matched with top window pros in Round Lake, IL

"Excellent price. Great job installing windows. Customer service very helpful. Had all windows replaced. Windows made in Illinois. Made a significant improvement on my heating bill."

"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."

"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."

"Set up appointment very quickly and explained pricing before they came out to the house. They not only fixed the sliding door but also fixed a screen and window handle and asked if I had any other window / door problems . Wow what service ! I would definitely recommend this company . Very polite and prompt too."

"Ronnie Barnes has great customer service. He responds quickly to emails and succeeds in helping the customer. Needed a cracked window replaced. The very same day, he looked at the window and gave me a quote. Window ordered; 2 weeks later it was installed within 20 minutes. Satisfied with the job and will use again."

"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."

"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."
