Great Company

Marge H.

We have used Illinois Energy Windows and Siding twice in the past 4 years for windows and a door. They are awesome to work with. Everyone was great. Prompt and professional. They kept our house clean during and after their work. I recommend them to everyone. Love their lifetime warranty and being able to transfer the warranty to the next homeowner.

Front Door

We had our front door replaced and it makes the whole house look so much better. The installation was quick and the installer was super friendly and communicated what he was doing, issues he found with our old door/frame, and made sure we happy before leaving. We loved the whole experience.

Quality Windows with a Guarantee

Jim R.

Illinois Energy has installed / replaced all the windows in my home. The last three windows were completed this year on the back and side of the home. They were on-time and completed on schedule. The windows were custom built and installed with very competitive pricing. My windows come with a guarantee while I live in the home. It is good to know that Illinois Energy has your back.

Great Results!

Juan P.

Recently had my gutters and 1 window replaced and absolutely love the results. Jobs were done quickly and kept me updated on the process. I've also had previous jobs done such as facia and soffits done by Illinois Energy. I will continue to use them for future jobs and highly recommend them.

Kitchen Door Install

Steve K.

I just wanted to leave a note about how well the door installation went on May 7th. Gerry did a wonderful job. The door looks great. He was very mindful about not making a mess and carefully cleaning up after he was done. I would be happy to have him again.

Illinois Energy Windows & Siding

Thank you so much for the great review! We're glad to hear you're happy with the door installation and that Jerry took good care of everything. He always aims to do quality work and keep things tidy so it’s great to know that showed. Please let us know if there is anything else we can do for you! Illinois Energy Management

Job Well Done

Tina B.

I was a little apprehensive when Jerry arrived (early, which was great) as he was by himself. I didn't think one person could do all the heavy-lifting on his own, but he did and did a spectacular job on top of it! We had an Anderson Door that was not installed properly and it was nearly impossible to open. the new door glides right open with very little pressure. I no longer need to lift weights to get my door open! Jerry did a gorgeous job on the inside and outside trim. The previous owners had done a very poor job outside and left the siding jagged with sloppy caulk work. Jerry did a miraculous job covering that up and making it look professional. We're sorry we waited so long to replace the old door.

Illinois Energy Windows & Siding

Thank you so much for the kind and thoughtful review! We're thrilled to hear that Jerry exceeded your expectations and delivered such a high quality result. He truly takes pride in his work and it's great to know his efforts made such a noticeable difference. We understand how frustrating that old door must have been and we’re so glad you’re now set up for a stress-free, easy-gliding summer. Thank you again for your business and support!
