Superb and Professional new windows
We engaged Illinois Energy Windows and Sidings for replacement windows at our 103 year old bungalow. We replaced old and failed vinyl windows and metal storms with heritage wooden windows as part of a historical preservation incentive program in Glen Ellyn. We could not be happier with the IL Energy team at every stage of the process. Tristan and Dom really cared about the new windows being historically accurate through the manufacturing process, including accurately matching existing windows we have. The installation day went very smoothly. The installation required on the ground problem solving which Dom and the team handled extremely well. Distressed and rotten window infrastructure needed to be replaced and the team replaced with historically accurate Douglas fir wood which follows the Illinois state historic renovation standards. The insulation around the window openings was non-existent and the team added high performance insulation material from which we have already experienced a noticeable improvement with internal temperatures of the rooms. A small problem with the Weathershield windows required an after care visit and the after care team handled this extremely professionally and diagnosed and fixed the problem in a short space of time. As we plan to replace more windows in our historic bungalow over time, we would ONLY ever consider using IL Energy Windows and Siding for this further window replacement work.

Sliding patio door replacement
I will definitely be doing business with this company again. They were knowledgeable, professional, and on time.
Great products and service
Used their services at our previous home. We knew they offered great products. Installation was completed in a day. Jerry was pleasant and very professional. Showed up timely, and left with beautiful doors and a clean workplace. Would recommend their services.
Great work, highly recommend!
I worked with IEWS to get three windows replaced in my house in Glen Ellyn and had a great experience. Starting with the initial sales consultation, Garrett walked me through all of my options and highlighted what I should (and shouldn't) consider when replacing the windows. For the installation, the team was in and out in less than 3 hours. Incorrect handles were initially installed (miscommunication on the original SOW), but the team came back out the next week to replace and everything looks great. Would highly recommend to anyone looking for a small, one-off window replacement, or a larger scale one.
Great Job on our Front Door!
Illinois Energy did a fantastic job with our front door, sidelights, and screen door. The installer was thorough and very skilled, and the door has an unmistakably solid feel to it. They will not be the lowest price if you are shopping around, but you do have to pay for quality, and that is what you will get with this company.
Wood window replacement
From the beginning to the end, Illinois Energy Windows & Siding is a fantastic vendor. I wanted to replace my older, medium quality, vinyl windows with wooden windows. From the initial sales call to the post-installation follow-up, every employee I encountered was profession, personable and prompt with all the responses. The sales team let the product sell itself, explained the pros and cons of various options and configurations and gave me plenty of time to make a measured decision - no up-selling here. The installers arrived promptly, had great respect for the house by taking the time to cover the furniture and keeping the time when the window was removed to a minimum before the new window was installed. Post installation I was contacted to see if I was satisfied. The whole experience was what I expected from a local business with great quality and products and grows from recommendations from satisfied customers. I am a satisfied customer and this is my word-of-mouth endorsement.
Replacement Windows
The team at Illinois Energy did a great job from start to finish. They replaced our gutters and 4 windows. The team was on time, polite and. Cleaned up after doing the work. The work they did was very professional and looked great when they were done. The materials were excellent. We would hire them again.
Custom door, sidelights and transom
