Windows and door

Jaya K.

We had Illinois energy install some new windows and a sliding door. They got to our house right on time, did a fantastic job installing them and answered all our questions, and finished within the time they told us. They cleaned up everything so that we didn’t have to do any cleaning after they left. Satisfied with their punctuality and the efficient service.

New Windows

Lydia S.

Several of our windows have been replaced with windows from Illinois Energy. Installation of the windows went smoothly, furniture was moved, and drop cloths protected our rugs. We were very satisfied with our choice of windows, and the excellent service we received from Illinois Energy.

Replacement Doors

Merle C.

We recently replaced a back door and a door leading into the house from the garage. The staff at Illinois Energy was 5-Star from start to finish. The installer arrived on time and stayed all day to complete the project. He was friendly, knowledgeable and diligent. He followed all safety and required protocols. He answered all our questions and advised us of all the features of the new products. We highly recommend this company. This was our second time using them and both experiences were 5-Star!

Great quality windows

Christine W.

All new windows have been installed and a beautiful upgrade from our 20 year old builder grade windows. No more draft. And I've noticed outside noise is diminished too. The installers did fantastic job and were respectful of our home and property, inside and out. Everyone we've had contact with from Illinois Energy was so pleasant to deal with. Thanks.

New Patio Door

Linda M.

I'm very happy with my new patio door. I didn't realize how hard it was to operate my old door until this new one was installed. It opens so easily and smoothly. I liked all the options I was given so that I was able to choose exactly the features I wanted! Everyone I worked with from Illinois Energy was knowledgeable, courteous, and helpful.

New windows, new views

Elek S.

I’ve worked with Illinois Energy a coup times in the past and was confident that I could expect the same level of expertise and professionalism. The workmen arrived on time and took all precautions to minimize and dust or debris. They were very courteous and answered all of my questions. Before I knew it, they were done and I was left with beautiful new windows and a new view of my backyard. I highly recommend Illinois Energy for all of the services they offer and will definitely recommend them to my family and friends. Thanks for the great windows!

Recently Illinois Energy Windows & Siding did a fabulous job installing a bow window, along with a few standard size windows in our home. The installation crew was quick and did a wonderful job cleaning up after themselves.

Make the call,

Ashley P.

Our experience with the team was excellent. Sean helped us with deciding on our product that worked with our budget. We appreciated the upfront value of time (as well as cost of course) when going over product options , especially as parents of two young kids. We knew we made the right choice of exterior door, and had a great install with Jerry. Thank you!
