Outstanding job!

MARY P.

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.

Great staff and wonderful company

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.

New patio sliding door

Helen R.

We had a new patio sliding door installed and the whole experience from start to finish in my opinion was GREAT. Very straightforward at first meeting, impressive warranty, kept in touch and products came earlier than expected. The installation itself was very neatly done and also very timely. This company was recommended from my BIL, who also did some windows for my MIL and we have all been very happy with their work. 5 stars here well done!
