Window installation
They did a fantastic job. They were on time and did the installation of a new picture window for me. The guys were very nice, they did the installation in a timely manner under the time they had extimated. They cleaned up after themselves, took the old window with them and even washed the window inside and out!! I was very pleased with the absolutely wonderful job they did!!
New Window Installation
Had a great overall experience with Illinois Energy, from the time we talked to the salesman to the install itself. Everyone was knowledgeable, professional, on-time and friendly. Also there prices are hard to beat. I would definitely recommend them and look forward to doing business with them in the future.
Excellent Company
Love my new windows. The windows are a great quality unlike the Pella windows I had that were rotting. The company made the process very easy and they were very professional! Would use them again.
Patio door replacement
The whole process was easy and kept us updated on timing for installation. Our patio door was replaced due to cold/heat entering throughout. once replaced the outside noise from the main street was a lot quieter!
Excellent service
We had a great experience using Illinois Energy for our sliding glass back door. The installers came on a very cold day and worked quickly to install the new door. As soon as the door was up, we could no longer feel the cold air coming through the door like our old one. By the time we were done admiring it, the crew had everything cleaned up and framed off. We will definitely be using them again for future projects.
Very satisfied with their job
They did an excellent job! The communication throughout the process was very good and clear and the workers were respectful, clean and efficient.
Our second project with IEWS
Excellent craftsmanship and beautiful product. Professional employees and installers.
Quality Windows
Excellent services from the start of the process, until the end. Punctual, Efficient, Excellent Communication, and installation was quick. The purchase price fit the window quality.
Patio Door
I'm a second time customer. This time I ordered a sliding patio door. I was informed from the time the order was placed to installation would be 6 weeks. I received a call within 6 weeks that the door has arrived and scheduled a date for installation. The day of installation the installers arrived and removed the old door and installed the new one. The installers were organized, neat and left the house clean. I would recommend Illinois Energy Windows & Siding.
