Upstairs windows
During the pandemic, we replaced our family room windows and sliding door. I shopped around and had 4 other companies come out and give us estimates. Illinois Energy Windows gave us the best price and had the best warranty. 2 years later, we went back to them to finish our upstairs. We replaced 8 more windows and again, price was reasonable. The workers for both of the times were very nice and really cleaned up after them selves. They moved all our furniture and returned it when they finished. This company has been around for over 20 years….they aren’t going anywhere! They also have the best customer service….this is a family owned business so make sure if you are looking for windows, support Illinois Energy Windows & Siding.
Excellent windows
I have had all of my windows replaced by Illinois Energy and I would highly recommend them. Everyone I have worked with has been great and very professional. The windows are really good quality.
IL Energy window replacement
We contacted IL Energy because a previous homeowner used the company in the past and were very satisfied. We are so glad we did. We had 2 sliding windows replaced and the new front windows look great. We appreciate the time and effort staff took to help us select the right windows. Our sales rep was so knowledgeable about the product and company warranty. Staff was easy to talk to and access by phone. They worked with us to accommodate our schedule and determine the best date of installation. It was a warm day, but staff worked tirelessly with great skill and courtesy. We would highly recommend IL Energy.
Five-Star Experience!
Working with Illinois Energy was the best decision we could have made for replacing our patio door! From start to finish, they were professional, responsive and went above and beyond to make everything work for us. The free estimate visit was booked quickly and their knowledgeable and friendly salesman was honest and transparent about their products and pricing as well as competitors. The day of installation was a breeze as all the work was completed in the morning and a minor unexpected discovery led to no additional charges at all. The customer service was excellent as they followed up to make sure everything went smooth. The incredible and thorough warranty coverage included with everything is truly the best peace of mind you could ask for. The leaking issues with the previous door are a thing of the past and we know this door will last us for the long run and save us a ton on energy costs. I highly recommend Illinois Energy for anyone looking for windows or doors!
Wonderful experience for returning customer
I had all of the windows in my home replaced by Illinois Energy. We used them for some exterior doors several years ago and had such a good experience that we remembered them and called them for the windows too. The work is very high quality, the installation crew was prompt and efficient and even accommodating to me while replacing the window in the room where I work from home. Overall a fantastic experience and would absolutely recommend
