Excellent Service!

Haley M.

We had a new door installed with Illinois Energy Windows & Siding and couldn't be more pleased! From the office staff to the installer, everyone was so professional and courteous. The door installation took one day total and my house was left as clean as when the installer arrived. I would definitely go back to them for my future needs!

Amazing difference!

Kimberly M.

I am very pleased with the windows that have been installed by Illinois Energy Windows & Siding, Inc. From the sales rep patiently answering all 101 questions I had about what windows would be installed, and why they were so good. Illinois Energy offered options for pricing, making it possible for me make this home improvement. The entire team was very professional, from point of sale, to the representative that took the measurements of the windows to be replaced, to the installers that arrived promptly on time. The installers worked quickly to install 7 windows the end of December. There were follow up calls from the office asking if I was pleased with the windows, the installation, and if I had any concerns. Customer service is part of the complete package that I do appreciate. Better yet, I can keep my curtains open now and not feel the cold draft that the old windows allowed.

Patio Door Replacement

Illinois Energy Windows & Siding Inc was one of the best companies I've dealt with, being a homeowner. From the initial consultation for our new patio door all the way to the installation. They stood by their word & their process was seamless. No doubt, I will highly recommend them

Windows look good

Alex L.

Illinois Energy Windows have a great selection of products. This is our second purchase with them because we have been very satisfied with the first project. The staff is very friendly and they really listen to your needs. There is no hard sell or pressure to buy. The installation crews have been really good on both projects. They arrived at our house on time and finished as promised. The crew was careful with their work. There were no messes left for us to clean up.

We love our new door


Illinois Energy Windows & Siding my husband & I could not be more pleased with our recent fiberglass door installation. Joe visited our home (sometime in October) for an estimate and was very well prepared with samples, pictures of past installations, manufacturer brochures and most importantly, his knowledge. We were sold with his professionalism! The day came and Jerry (the installer) was very well-trained and he was totally professional. The install area was well protected, dust was minimized, debris was cleaned up and the quality of the workmanship was quite excellent! Jerry got it right the first time which, unfortunately, is all too rare these days. Way to go Jerry and many, many thanks!!! In conclusion, we are most pleased with the outcome and will certainly be recommending them to my friends, family and co-workers for their window and door needs!!!

Excellent From Start To Finish

Kim K.

My experience from start to finish was exceptional. I had old wooden windows that were starting to rot and wanted new white vinyl windows. Vince was very helpful and friendly in the showroom. Then Brian came out to my house the next day to explain the whole process, take some preliminary measurements, brought an actual window, showed me videos and gave me a complete quote. I committed to the project at that meeting and got pre-approved for the financing. He was very prompt and professional. Then Dominick came out to do the final measurements. The installers were also prompt and laid down tarps everywhere. They came out despite the freezing cold weather and installed 7 beautiful windows in a timely manner. I spoke on the phone to the general manager and to Jill and Shelby. All called when they said they would and were very helpful and professional. I highly recommend Illinois Energy Windows & Siding!
