Excellent experience with new Windows.

Greg P.

Sales was very helpful in walking us through the process and options. The installers were excellent. They worked fast, clean, and efficiently. They answered all questions we had. They were very respectful. We are very happy with the work done and plan to eventually have the remainders of our windows replaced by IL Energy.

Beautiful windows

Michelle C.

The customer service of Illinois Energy is top notch! We went through 5 years with this company doing our windows in sections. Every year they were great. It didn't matter which service techs came out. They clean up after themselves too which is awesome!!

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.

We appreciate this feedback, Dan. Thank you for taking the time to go over your experience planning your project with James, the install process, and our follow up call as well. Thank you for choosing Illinois Energy to complete your window project, we know you'll enjoy the new windows for a very long time!
