We are repeat clients of Illinois Energy (IEWS). Our first project with them was replacement of a large slider family room window, a few years back. They did a wonderful job with that: excellent service, install and follow up. This year, (2026) we once again chose Illinois Energy to replace older windows in our kitchen and all bedrooms. It was good to work once again with our efficient and knowledgeable sales/marketing person, James, to set up the project. Their Worthington Windows are very well-made and constitute a significant home upgrade with a transferable lifetime warranty. The install crew arrived on-time. They were a courteous and skilled team that cleaned up the work site completely when they finished. It was another great experience with Illinois Energy! We recommend and look forward to working with Illinois Energy again in the future!
