We love our beautiful new front door!

Emily O.

I highly recommend hiring Illinois Energy for your next home upgrade. This was the first renovation we’ve done since moving into our new home and we’re so pleased. From start to finish the process was easy and all our questions answered. Their professional installer was amazing. He told us what he was going to do every step of the way and was so tidy. What a great experience and the front of our home looks amazing!

3 doors installed

Ken H.

We're returning customers with Illinois Energy from a job in 2014 and have called again for 3 more doors. We met with Anthony and Jim beforehand and the job was completed as promised. Our installer Jerry did an excellent, thorough 2 day job. The caulking was neat and clean up complete. He also went an extra step, fixing a previous door issue.

It's great to hear everything went smoothly and that Jerry went the extra mile. We appreciate your continued trust and look forward to helping with any future projects! Illinois Energy Management

Fully satisfied customer

Megan G.

Illinois Energy Windows & Siding was such a pleasure to work with. Our old front door was a double door, original to the home built in the 90’s. The draft was so bad! I looked around and found IEWS and the reviews looked promising. I called and made an appointment and James came out who was very kind, knowledgeable, and helpful in choosing the right door for us. The installer, Jerry, who came out was so thorough and paid great attention to detail with the install. No messy caulking, everything was pristine. The door is gorgeous. It transformed our house! We will certainly be using IEWS for future needs we have around the house.

Going with Illinois energy was the Best decision

Karen B.

I have had my windows and doors for 10 years now and I am still just as pleased with them as I was when they were first installed. It was the best home improvement project to date and Illinois energy was and still is professional in every way. They come to replace some torn screens from time to time, other than that…I have had zero issues.

Sliding Door

Renay B.

We had an amazing experience with Illinois Energy and Siding. We had a sliding patio door installed and it is beautiful! The quality and attention to detail with finishing touches exceeded our expectations. From meeting with Derek, the salesman who was very knowledgeable and prepared to discuss the product, was easy to talk to and, was very patient with any and all questions we had. To Jerry, the installer who is one of the hardest working craftsman we have ever encountered! He was promptly on time, kind and gracious in our home and went above and beyond to help fix an area in our house that we were not expecting. We cannot say enough great things about Illinois Energy and Siding and we definitely recommended them and will be using them in the future.

The door and the bay window look terrific. The guys that installed them did a great job; they were fast and efficient. The salesperson was very knowledgeable as well about window products in general.

I love my new windows!

Amanda L.

Good! My first time getting new windows. It's a BIG purchase. I feel confident in my purchase and love my new windows. They are beautiful! I feel safe choosing this company because of the exceptional warranty. They were easy to work with, the company seems very organized and everything went smoothly. I was stressed about having a mess to clean up after they installed but there was not a mess. They cleaned up everything! And my interior trim wasn't touched/damaged at all... I was worried about that. It makes a huge difference in the look of my home. I love the windows!
