★★★★★

Illinois Energy employees got here right on time and finished the work without any problem. They did the work very efficiently and finished the work on time. They cleaned up the whole thing that we didn't have to do anything after they left. Very satisfied with their work and punctuality.

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.

Just had our new windows installed and we're very happy with the quality. The installers were very respectful of our home and property and did a beautiful job with installation and clean up. I even noticed that I hear less noise from outside! Glad we got this upgrade to our home.

We were so pleased with our experience with our windows and patio door installations. The two Illinois Energy installers arrived on time. They immediately laid tarps and put up plastic shields to contain the dust. They worked efficiently and cleaned up when they finished. We highly recommend them.

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.

This review is another review for Illinois Energy Windows and Siding, Inc. I recently had them install a patio door. I was very pleased with the products and excellent customer service. They responded quickly to any questions/concerns I had during the process. Just as before, the installation went smoothly, and the installers arrived on time, explained everything to me and cleaned up thoroughly. I plan to use them again in the future to replace additional windows. I also like the lifetime warranty they offer with their products and service.

They recently replaced 2 half moon windows in my townhome. I had many plants in the front yard near the windows which they were very careful not to destroy. They worked carefully and quickly. I had minimal cleanup when they left. I did not even have to repaint the interior of my house and nothing was damaged as a result of their work. I have used this company before and will use them again.
