We had a great experience all around at Illinois Energy Windows & Siding. We walked into the showroom and were greeted by a friendly face, who linked us to a salesman. At the in home consultation we were walked through options, pros/cons and pricing in a thorough, relaxed and pleasant manner. The options we chose (a very cool door, btw) were installed within the promised time frame and exceeded our expectations in appearance, functionality and insulation (installed on a very cold day). The installer was great, speedy, detail oriented and efficient. He walked us through the ins and outs of the door (lol), and left our place cleaner than when he started, I'm embarrassed... read full review

We just had our sliding glass patio door replaced, our old one was drafty, and didn't want to slide easily any more. Illinois Energy Window & Siding Inc. came in and installed a new one. Awesome job from start to finish. From our initial consultation to the install of our new patio sliding door every step was professional and done well. So happy with the final results

The installers were absolutely amazing!!!! They went above and beyond! They moved my Gazebo enough to make sure the storm door wouldn’t hit it when opened! They cleaned up all the mess and were quick at getting it all done! So very polite and kind. Now all of my windows and doors were replaced by Illinois Energy along with our roof.
