We had a fantastic experience with Illinois Energy Windows and Siding! From the start, our sales rep was knowledgeable and thorough, and the warranty—especially on the installation—gave us real peace of mind. Our custom sliding glass door arrived earlier than expected, and the installation crew was professional, clean, and worked efficiently—even through less-than-ideal weather. The new door is a huge upgrade from our old one—it glides effortlessly, locks easily, and looks beautiful inside and out with flawless trim and caulking. We’re so happy we chose this local company. Highly recommend!
