"Illinois Energy Windows & Siding, Inc. recently replaced all our windows and a patio door. We couldn't be happier. They are much sturdier than our previous new construction builder windows, they look great, and they add nice curb appeal to our home. On an unseasonably hot spring day right after install, my husband entered the house and thought I had the air conditioner on. I didn't! That seems to be a good indication that these windows will greatly improve our energy efficiency. The two installers were professional, efficient, thorough, and respected our home and property. We did have an issue with extremely high winds and a couple pieces of siding soon after the install, and the service department was out immediately and took care of the problem. We feel we received quality windows and quality workmanship, and we highly recommend Illinois Energy Windows & Siding, Inc."Carole McDonald
"We have used Illinois Energy Windows and Siding to replace all the windows in our home as well as the sliding door out back. From our first communication with them, they have been nothing but professional. Replacing windows and/or doors is a huge investment, and we researched and spoke to other businesses before we went with Illinois Energy Windows and Siding. After the initial installation, any issues or questions were immediately addressed with no hesitation. Although they didn't have the lowest initial quote, what we ended up with was great communication and customer service, professional installers, a great warranty, and great looking, sturdy and reliable windows (and sliding back door) that will last a long, long time. Overall, what we received from Illinois Energy Windows and Siding is quality. No regrets here."Darnell Ramiscal
"We used this company over 20 years ago to replace windows in a previous house. When we needed a new front door package for the current house we chose them again. Products are outstanding quality, fairly priced given the quality and all processes are completed from order to install with upfront honest communication. The installers are wonderful, knowledgeable and very courteous."Tina LeBleu
"My experience with Illinois Energy and Windows could not have been more positive. I contacted them for a new front door and sidelight window in June. My initial meeting to full installation took about 2 months - exactly as promised. On the day of install (a Saturday, so I didn't have to take a day off of work) Rob and Paul arrived on time, worked steadily and competently to remove my storm door and the existing front door/sidelight window. They were constantly cleaning up as they went and worked seamlessly to install my new door unit and reinstallation of my storm door. Rob was amazing! His care and concern to make sure everything was perfect made me feel like he would have paid the same attention to detail if it was his own house. They even cleaned off the spider webs from my front porch so the door would look fabulous!! I love my new door and appreciate the financing options that were offered to me. You can't go wrong if you choose this company."Leslie Kruzich

"We replaced all of our upstairs windows with Illinois Energy. The windows look fresh and the installation process was easy. They look great and are much better than our name brand Pella windows that we previously had. We appreciated the great customer service and follow up. We are planning to replace the rest of the windows in our house in the future with Illinois Energy Windows. We highly recommend these windows to other home owners. Our sales rep Jason was courteous and professional through the whole process."
