Great Experience, Great Windows

Amanda T.

My husband and I had a wonderful experience with Illinois Energy! They met with us and explained all our options and gave us plenty of information about the windows they provide and how the installation would work. The day of the installation, they were professional, quick, and did a beautiful job with our windows. We would highly recommend them to anyone thinking about new windows.

Happy Customers

Michelle S.

We recently had a fantastic experience with Illinois Energy for our new door installation. Choosing our door with the sales representative was simple, informative, and seamless. They took the time to guide us through the options, making the whole process stress-free. The installation was excellent – high-quality work that truly stands out, and our new door looks amazing. We couldn’t be happier with the results. We will definitely be using Illinois Energy again when it’s time to update our front doors. Highly recommend them for anyone looking for top-notch service and craftsmanship!

New Windows

Luis D.

We purchased windows for our house and the process was very easy. The entire staff was great to work with from signing the documents to completing the installation. The crew was terrific. They treated our house as their own, cleaning up everything both inside and out. The crew even had to contend with one of the window openings needing to be adjusted for size. They crafted a new fitting complete with new casing and even painted it with the paint we had. We would highly recommend them.

Emily O.

I highly recommend hiring Illinois Energy for your next home upgrade. This was the first renovation we’ve done since moving into our new home and we’re so pleased. From start to finish the process was easy and all our questions answered. Their professional installer was amazing. He told us what he was going to do every step of the way and was so tidy. What a great experience and the front of our home looks amazing!

3 doors installed

Ken H.

We're returning customers with Illinois Energy from a job in 2014 and have called again for 3 more doors. We met with Anthony and Jim beforehand and the job was completed as promised. Our installer Jerry did an excellent, thorough 2 day job. The caulking was neat and clean up complete. He also went an extra step, fixing a previous door issue.

Illinois Energy Windows & Siding

Thank you for coming back to work with us again, it really means a lot! We're glad Anthony, Jim, and Jerry were able to deliver the same high level of service you’ve come to expect. It's great to hear everything went smoothly and that Jerry went the extra mile. We appreciate your continued trust and look forward to helping with any future projects! Illinois Energy Management
