Excellent windows and service!

M C.

I recently had new windows, patio doors and front doors and storm doors installed at both at my home and a condo we own. We are beyond thrilled with the final product, installers, and service personnel. Our Salesman, Tom was excellent as well and very fair and accommodating! We highly recommend this company!

Window and patio sliding door replacement

Mike F.

Everything went great with our replacement project from the sales person all the way to the installation. All the people we dealt with where courtesy and professional. The installation only took two days for ten windows and a sliding glass door. The installers left our house as clean as when the left as it was before they started. The windows and door seem to be much better than our previous ones. Thank you from a happy customer.

Great to work with

Daniel R.

We are very pleased with our new windows from Illinois Energy. We equally were pleased with the team at Illinois Energy. They were easy to work with by being helpful and responsive. We have a historic home with original windows and James took the time for us to understand the process and even came out separately with pieces so we could see some options on the window before making a final decision. Installation was done quickly with total clean up before they left. Great follow up to ensure we were completely satisfied. Would definitely recommend them and wouldn’t hesitate using them for future needs.

Beautiful siding around the house

Gerald R.

House was in need of updating. Called and got a great price for high quality siding. Reps were professional , workers were amazing. They were neat and very respectful of property. House looks like new and am sure the $value went up. So satisfied to have this done.

Great Service...Great Products

Nick H.

We used Illinois Energy on 2 separate jobs which includes 5 windows and a patio door and we loved using them. From the sales process all the way through they were thorough, responsive and high quality. We liked them so much we used them 2 times and both times was a great experience. I am beginning to get tired of big corporations churning through clients so when I find a company like this that is a local business that does great work I am happy to recommend them. They are great!
