Great Installation
The sales process was very professional and provide complete information on the product. The installation crew was fantastic; they were very professional, explained everything in the process, were neat, very polite and provided a great installation. I would recommend them to everyone I know.
5 stars
I had all my windows replaced by Illinois Energy Windows & Siding and the experience was excellent from start to finish. The installation met the standards I expected and they checked in afterward to ensure everything was right. They are on the pricier side, but you get top quality and what feels like the best warranty money can buy from a company that has been around for years. I highly recommend them.
Best Decision!
We are extremely pleased with our decision to use Illinois Energy. We had complete window replacements along with a large bay window replacement this summer and Fall. Additionally, we had our roof, gutters, soffit, and facia replacement done this spring. The work was done in a timely manner, workers were efficient, and clean up was thorough. The process from start to finish was excellent. We would absolutely recommend them.

Great Sevice
Exceptional Window Replacement Experience with a Truly Local, All-in-One Company We had our windows replaced in our house by Illinois Energy Windows and Siding from Lisle. My wife and I were specifically looking for a company local to the Chicago area where sales, production, installation, and service were all handled by the same team. Many companies rely on subcontractors, and we weren’t interested in that. We wanted one-stop shopping—and we got it with Illinois Energy Windows and Siding. The salesperson was very informative, walking us through our options from window styles to materials. He was also mindful of our budget and worked with us to stay within it. Once the windows were ready, the installers arrived on time and were extremely conscientious. They laid tarps to protect our wood floors, were friendly and professional, and cleaned up thoroughly—both inside and outside. They even dusted all the windowsills. After installation, they took the time to show us how the windows operate, how to clean them, and explained the security features. The follow-up from Illinois Energy Windows and Siding was reassuring. They genuinely wanted us to be completely satisfied—and we were. I would highly recommend anyone in the market for house windows to give them a call and let them take care of your window needs.
Three doors down!
We had three doors installed by Illinois Energy Windows and Siding. The experience was seamless from start to finish and the installation was professional. I have a new appreciation for the craftsmanship and endurance required to replace doors the right way! Our sales expert (Mike Kuta) was available to answer any questions and provided personal attention throughout the process. Highly recommend!
Lovely Bay Window
We couldn’t be more pleased with our new bay window. The entire process was seamless from the easy scheduling and efficient installation. The installer was not only professional but also friendly, taking the time to answer our questions and explain how to operate the windows. The service exceeded our expectations. We highly recommend this company and truly appreciate the excellent work. We will definitely have more projects with them in the future. 😊
Love my NEW Window!!!!
After seeing Illinois Energy working in our neighborhood and seeing the work they had done on a neighbors home...I called to ask for a quote to replace our window. They promptly returned my call and scheduled a time to assess what I wanted and Needed. I needed a large bow window to be replaced, and knew it would be more expensive....however the young man who came showed me other options that were less than other quotes we had received from another company. He was able to share photos of other projects they had completed (both the before and afters ) and we didn't hesitate to schedule our window replacement. Less than 2 months later the window was in and replaced 7 days later! The workman who installed the window were Wonderful. they began with covering furniture and flooring and ended with cleaning the window and vacuuming the carpet. The entire installation was like watching a master craftsman. My husband is retired from the "trades" and was impressed with the attention to detail, efficiency of the process....whilst the wife (me) marveled at how neat they were.... We are retirees and enjoyed the service they performed and their kindness. Thank You Illinois Energy for making me the Happy Wife with a Beautiful NEW Window!!
Sliding door replacement
Paul was very detailed in a way that made things go by quickly. The way he described the process is how it happened. The installers were on time and very quick with the installation while leaving the area neat. The doors were installed recently, so we will update if anything changes, but they operate smoothly so far. There is a short period where they are a bit tight after being installed, but then they are easier to use.
