  We recently had our front door replaced by Illinois Energy Windows and Siding and had a very positive experience. Our initial salesman was very knowledgeable and did a good job of laying out our options without being pushy. The workers that came to the house were professional, did quality work and cleaned everything up at the end of the install.

  I had two oversized sliding doors and four adjacent windows replaced. I was impressed with how closely the inside and outside colors matched the house. I was impressed with the workmanship and how well they cleaned up the site.

  When we moved into this house in 2016 we received the unfortunate news that all of our windows needed to be replaced. We took a chance on Illinois Energy Windows & Siding because of the attention to quality they put into not only manufacturing their windows but also installation. Their installation crews are very professional, respectful, and do quality work. We are very pleased with our windows and couldn't be happier with the peace of mind they bring.

  We recently had our sliding glass door replaced by Illinois Energy Windows and Siding, and we couldnt be happier with the entire experience. As a family of four with two growing kids (ages 11 and 13), our home is full of energy and activityespecially in the backyard, where we have a pool and spend a lot of time cooking and entertaining on the deck. Having a high-quality, dependable door that connects our indoor and outdoor living spaces is essential, and this upgrade has made a noticeable difference.From the start, our sales representative was fantasticthorough, informative, and patient as we discussed our options. What really stood out to us was the companys incredible warranty package. Knowing the installation itself was covered gave us extra peace of mind, and honestly, it was one of the main reasons we chose Illinois Energy.The custom-built door arrived even earlier than expected, which was a pleasant surprise. When installation day came, the crew was professional, efficient, and impressively clean. Despite some rough weather in the area, they worked diligently and took extra care to protect our home throughout the *********** that the door is in, were amazed at the difference. We replaced a Paella French-style slider that always required two hands and a good tug to open. This new door? We can slide it open with a single finger! It glides so smoothly, locks easily, and feels incredibly sturdy.Visually, the finish work is impeccable. The crisp white interior trim and flawless caulking look fantastic inside, and the exterior brick molding and trim work are just as beautifully done.Illinois Energy Windows and Siding exceeded our expectations from start to finish. It's clear they care about quality and customer satisfaction, and were so grateful we chose them for this project. Highly recommended!****** and ****
