😀👍We love our new Illinois Energy Windows ! We are completely satisfied with our experience with Illinois Energy Windows & Siding, Inc. We had four new windows installed in our 33‑year‑old single‑family home, and the entire process was smooth and professional from start to finish. Sales representative Paul Girzynski thoroughly explained and demonstrated the benefits of the new windows, making everything easy to understand. He provided us with a very fair quote for the four windows, and we were comfortable moving forward right away. Shortly after, a window specialist from Illinois Energy Windows & Siding, Inc. came out to take precise measurements. Within what felt like about a month, our windows were ready for installation. A team of four installers completed the job in approximately four hours. They took the time to explain the features of our new windows, including the latch‑release system and the ability to clean the windows from inside the room—an amazing and very convenient feature. Best of all, we immediately noticed improved comfort in our home. Our rooms are warmer in the winter, cooler in the summer, and overall much more enjoyable. We are extremely happy with the quality of the windows, the workmanship, and the customer service, and we highly recommend Illinois Energy Windows & Siding, Inc.
Hardworking professionals installed twelve new windows in our house. We couldn't be happier!
I had the pleasure of working with Illinois Energy Windows & Siding after soliciting proposals from several established companies for the same scope of work. The pricing was competitive and the warranty terms were comparable to other vendors in the market. The primary factors influencing my decision were Illinois Energy's strong reputation, their longevity in the industry, and my preference to support locally-based Illinois companies. The craftsmanship demonstrated by the assigned installer was exceptional and reflected in the quality of the completed work. He reconstructed the entire door frame and installed two high-quality doors—the rear entry door and storm door—both of which significantly enhanced the aesthetic appeal of the property. Additionally, he replaced the transom window above the door, which complemented the overall installation beautifully. The installation has eliminated all drafts from the rear entry. Even with the primary door open, the storm door provides an effective seal with no air infiltration. The door seals are robust, creating noticeable pressure when opening and closing, which confirms proper installation and weatherproofing. The installer demonstrated meticulous attention to detail throughout the project, ensuring all work met the highest standards. Upon completion, he provided a comprehensive walkthrough of all installed components, supplied multiple key sets for the doors and deadbolt, and explained the operation of the integrated screen and internal blinds. He also demonstrated the storm door's seasonal functionality, including the transition between screen and glass configurations. Communication throughout the project—both with the installer and the company—was clear, precise, and professional. Scheduling was executed flawlessly with no confusion regarding appointment times, arrival windows, or project duration.
