Promise kept, 100% happy

Tienie E.

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.

Window replacement

Lynne S.

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.

New Front Doors after 47 Years

Sandy W.

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.

Great Craftsmanship and An Honest Company

Claire T.

We had an outstanding experience ordering our front and back entrance doors from Illinois Energy Windows & Siding. Before contacting them we had gotten a quote from a competitor and definitely had sticker shock, after that we scheduled a meeting with Illinois Energy & Electric. They were able to meet with us quickly and the rep we met with, Paul, was on time, friendly, helpful, and gave his honest opinion. The doors came within the estimates time frame and installation was scheduled shortly after. Our installer, Jerry, was on time, very courteous, and did a fantastic job with both taking out the old as well as installing the new. I also appreciated that they also do their own installations and don't outsource them. Overall we have been more than happy with our experience. The doors look great!
