I am very pleased with the windows that have been installed by Illinois Energy Windows & Siding, Inc. From the sales rep patiently answering all 101 questions I had about what windows would be installed, and why they were so good. Illinois Energy offered options for pricing, making it possible for me make this home improvement. The entire team was very professional, from point of sale, to the representative that took the measurements of the windows to be replaced, to the installers that arrived promptly on time. The installers worked quickly to install 7 windows the end of December. There were follow up calls from the office asking if I was pleased with the windows, the installation, and if I had any concerns. Customer service is part of the complete package that I do appreciate. Better yet, I can keep my curtains open now and not feel the cold draft that the old windows allowed.
