Window review
Great customer service and beautiful windows. Nice job installing and clean up ! Second home we used your company for, and are well pleased .
Custom Sliding Door Install
They did a great job on our patio door. The new door glides like an Olympic skater. Installation was pretty quick and quiet and didn't leave a mess. I'd have them back for another project.
Great Company to do business with
I have used Illinois Energy Windows and Siding at my current residence and at my previous residence. I am very happy with this company. The windows are high quality and have helped keep my heating bills down during the winter months. They kept me informed of the installation process. Their installation crew was professional and cleaned up after themselves. Illinois Energy Windows & Siding stands behind their product and has great customer service. I would recommend this company.
Replace window
Fabulous! Our entire experience was great. This is our second project, and everything went very smooth. Top notch service. I can’t say enough good things about them.
Promise kept, 100% happy
I had all my house’s window frames replaced by Illinois Energy and it looks great. Had an issue with one frame but IE stuck to their promise of no payment until I am 100% satisfied and got the problem addressed with great skill and professionalism (thank you Nate and team!) The quality and workmanship is fantastic and I recommend IE hands down.
Basement Windows and Doors
Good quality windows and a lifetime guarantee on window installation. Windows and customer service are fantastic!

This is the second time we’ve used Illinois energy. We replaced 1/2 of our windows several years ago and the remainder of them recently. Very professional and easy to work with.

Window Replacement
The whole process from selecting new windows to the physical replacement was very easy. They were flexible to my schedule. The crew that came to replace the widows were professional, courteous and on time. They cleaned there mess. They were respectful to my pets. Thank You for a job well done!
New Front Doors after 47 Years
From the initial meeting to installation, everyone was courteous, on time, and able to answer all my questions. I love my 47 year old new doors. I went from a dark brown metal to white outsides and a blue gray inside. The addition of glass at the top brightens up the inside foyer. Appreciated the non pushy attitude of the salesman. I figured if the company was as good as he was I was in good hands and I was right.
