New Sliding Glass Door - AMAZING
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!
Excellent patio door & installation project mgmt
I had a new, custom, patio door installed from Illinois Energy Windows & Siding - July 2025. My new patio door is a great product and the company’s sales / ordering / installation process from requirements gathering, to project review and measurements to product delivery timeframe to installation (prep-install-cleanup) and final billing were one of the best renovation project management processes I’ve experienced. (and I’ve gone through several with various companies over the last two years). I was replacing an existing patio door that was 50 years old with a broken screen and a wooden base starting to rot. I paid a little more for quality, warranty & experience (than other bids I received) but with the final product along with Illinois Energy Windows and Siding’s exemplary professionalism, communication, experienced & detail-oriented installation people, I felt the price was well worth it! Their teams communicated the process from start to finish, expertly managing my expectations regarding each part of the project. The installers were experienced and very respectful of my property, well preparing the work area to contain the construction debris both inside and outside as well as doing a great cleanup job after. The new patio door is fantastic; beautifully trimmed, well insulated and with a smooth, easy, gliding (open-close)! I highly recommend Illinois Energy Windows & Siding for your home projects.
Distinctive doors and installation
My husband and I visited the IL Energy Windows and Siding showroom and were impressed by the quality appearance and functionality of the many styles of doors on display. Since that visit we purchased a new sliding door to our deck and, somewhat later, a new front entry door and sidelight. The price quoted was slightly higher than competitors on the sliding door, but, because of repeat customer discount, very reasonable on the front entry system. What sold us was the straightforward presentation by the sales representative, Derek, with no pressure and no blanket criticism of competitors products. We have endured too many sales presentations that insult our intelligence, Derek knew he had a high quality door at a fair price and conveyed that effectively. We love both the sliding and entry doors. The glass in the sliding door did not radiate the cold air during bitter winter days, as our previous door had done. The entry door is just recently installed, but the look is modern and clean-lined as we wanted and the installation was impeccable. We are proud of our choices and am grateful to all the staff at Ill Energy for their professional and personal service.
I Love My Half Moon Windows!
This is the 2nd time I have used Illinois Energy to replace my home windows. I had 2 different type of installations and could not do all at once. so they completed the last phase in June of this year. I worked with Nate who had great patience with my home owners organization in order to get their approval. The people that work for this organization took great care with my outside plantings as well as inside the house. Their method saved me hundreds of dollars because I did not have to replace window treatments or repaint the interior or exterior of my home once the new windows were installed. There was also minimal cleanup inside the home once they left. Would definitely use them again.
Professional and respectful
Professional and respectful crew. Treated our home respectfully and cleaned up perfectly. Beautiful doors.
Excellent windows
I have had all of my windows done by Illinois Energy. The windows are great quality and everyone I have worked with has been really great.
Lor and Lonnie Review
The price was expensive but the quality of the product was worth it. The install time frame was great. The installers were quick and professional and did a great job. They showed me how the windows worked and I was so impressed. I will get the remaining 5 windows fixed next year with this same company. 10/10!!
New Windows and Door
I would give Illinois Energy an 11 out of 10. Great products and the people are fantastic. This was our second round wih them replacing the rest of our windows and front door.
Illinois Energy Windows and Doors
This review is another review for Illinois Energy Windows and Siding, Inc. I recently had them install a patio door. I was very pleased with the products and excellent customer service. They responded quickly to any questions/concerns I had during the process. Just as before, the installation went smoothly, and the installers arrived on time, explained everything to me, and cleaned up thoroughly. I plan to use them again in the future to replace additional windows. I also like the lifetime warranty they offer with their products and services.
Windows and door
We had Illinois energy install some new windows and a sliding door. They got to our house right on time, did a fantastic job installing them and answered all our questions, and finished within the time they told us. They cleaned up everything so that we didn’t have to do any cleaning after they left. Satisfied with their punctuality and the efficient service.
