Highly recommended

Peter A.

I used Illinois Energy Windows & Siding, Inc. and highly recommend them to anyone in the market for windows and/or siding. They were very accommodating anytime I had a question or concern and they answered everything in a very timely fashion and I got exactly what he wanted for very reasonable pricing!

We got 3 smaller windows installed to replace our very old and drafty ones. Our new windows are easy to open and close, we love the safety locks and they are already less drafty in this cold weather!! The install team was small and came out two days. Both people were conscious of keeping our house clean and taking their shoes on/off. We had a great experience with installation. The quality of window is also a huge improvement from what we had and we will be using Illinois Energy again in the future when we are ready to replace more windows!

I highly recommend Illinois Energy Windows & Siding. The installer was on time, very professional, cleanup was excellent, and the instructions for maintaining the sliding deck doors were clear. The installation of the doors was in late November. My indoor plants required that the room temperature must be +70 degrees. The installer took great care in protecting these plants. Thank you.

Kim F.

Getting a new double front door and storm doors was a pleasant experience from beginning to end with this company. We received our estimate with Joe who took the time to really explain everything in detail, and set us up for a successful experience. The installation of the doors took 2 days and Jerry our installer was excellent. There were sever things that happened where he had to pivot and do things a little different, but he kept us informed the whole time. We are very pleased with our new front doors and Illinois Energy. Highly recommend them for your needs and we will be a repeat customer.
