Great experience on Windows/Doors project

Roniva I.

I have used Illinois Energy Windows & Siding twice - once last year to replace my front window and door and once this year to replace all the remaining windows and the patio door. The salesperson was extremely helpful and provided me with all my options and ways to save money. The installation was right on schedule for the front door and window, and about a month ahead of schedule for the rest of the windows. The installers were on-time, fast and efficient (a combined 3 days only to install 12 windows, a front door, and a patio door) and they went above and beyond in replacing rotted boards around the front door. There were a couple minor issues that were quickly and easily addressed, but nothing to prevent me from the rating I've given. Overall, a great experience.

We received excellent service from Illinois Energy Windows & Siding. From speaking with the salesman and selecting our windows and doors, to be kept apprised of the status of our order, and ultimately the installation process. Everything was completed on time and the final result looks amazing. Very satisfied with this company and would recommend to anyone looking to install new windows in their home.

Patio doors

Debi H.

Our experience with Illinois Energy was great from start to finish! The rep from the company was very informative and answered all of our questions. The crew that installed our doors were just as great. They were efficient and cleaned up everything when they left. You wouldn't have know they were even here. I would highly recommend this company!

We called Illinois Energy Windows & Siding Inc. to provide us a quotation for our windows. The salesperson was very thorough in explaining the design of the windows showing us an actual one, how they will be installed and their warranties. The process to get the windows on order and permit went very smoothly. I had changed the design after the windows were on ordered and we had no problem at all making the change. The people who assisted us with the change were helpful, friendly and pleasant. The windows actually came in before the due date and were scheduled to install right away. The Installers were courteous with our property and inside the house. When they finished installing everything was cleaned up before they left. I would highly recommend them!

We had 10 windows replaced and are very pleased with our install. The crew was polite and extremely efficient. They completed the entire project to include new trim and sills in less than 7 hours. They arrived on time and cleaned up well. The windows are beautiful and working perfectly

Patio Door Install

Scott S.

I recently had a patio door installed, and I couldn't be happier with the results! The entire process was smooth and hassle-free, from the initial consultation to the final installation. The team was incredibly professional and punctual, arriving exactly when they said they would and completing the job within the promised timeframe. The quality of the patio door is outstanding. It's both beautiful and functional, seamlessly blending with the existing decor of my home while providing excellent insulation and security. The materials used are top-notch, and you can tell that a lot of care and precision went into the craftsmanship. The installation crew was polite, respectful, and highly skilled. They took the time to explain the installation process to me and made sure I was comfortable with every step. They also left the area spotless, which I greatly appreciated. The new patio door has transformed my living space, letting in more natural light and providing a stunning view of my backyard. It has made a significant difference in the overall ambiance of my home. I wholeheartedly recommend this company for their exceptional service, quality products, and meticulous attention to detail. If you're considering having a patio door installed, look no further – you won't be disappointed!

Front door replaced

Jerry S.

Very easy process from sales to final installation. Everyone was very professional and answered all my questions. Quality door and great craftmanship by installer. 1 day install for exterior door and screen door. I would use them again for any future work I have done.

Patio Sliding Door

Myra L.

Used IEWS to replace our patio sliding door. The new door was made and ready to install around 2 weeks upon signing the contract, which is a month earlier than estimated. The installation went smoothly and was finished in about half a day. The door is much improved from our previous door and noticeable difference in the quality. The glass and screen door slides effortlessly. The glass door doesn’t close all the way unless you push it hard. So far, it seems fine and we shall see how it holds up over the next few years with the seasonal changes. Overall, we are happy with the service with IEWS and will use this company when we are ready to replace our windows.
