Great experience

Jerry M.

This was one of the best experiences I’ve had with a contractor in 20 years. Work was professional. Office people were great. I will do business again.

We were very satisfied with the process of getting our new windows installed. Everything went very smooth and easy from the first meeting until the install. We will definitely be using them again on future projects!

Great Service...Great Products

Nick H.

We used Illinois Energy on 2 separate jobs which includes 5 windows and a patio door and we loved using them. From the sales process all the way through they were thorough, responsive and high quality. We liked them so much we used them 2 times and both times was a great experience. I am beginning to get tired of big corporations churning through clients so when I find a company like this that is a local business that does great work I am happy to recommend them. They are great!

Great quality doors and windows

Kathryn S.

I received bids from a few companies, but this one had the best quality and warrantees. So glad I went with them! They did a great job with the installation of my bay window, front door with sidelight and back door! They had great options to pick from and could show me samples in their showroom nearby so that I knew what it would look like (much better to picture than just looking in a brochure/book). I will definitely be using them again for the next set of windows I need to replace!

We love our new windows!

Carole M.

We recently had Illinois Energy Windows & Siding do a whole house window replacement. Wow! What a difference! We love them! Not only does it make the house look better, but we immediately noticed that the house is quieter, and on a unseasonably hot, early spring day the house stayed cool inside. These are quality windows, and we couldn't be happier. The process was easy from start to finish -- Michael was a pleasure to work with when we got the initial quote, and the installers were professional, thorough, and were very respectful of our home and property. We highly recommend Illinois Energy windows, and we highly recommend Illinois Energy Windows & Siding, Inc.

Sliding door

Katherine M.

I didn't know what to expect as this is the first time I've tackled a project like this. Illinois Energy walked me through the whole process step by step. During our consultation I learned how Illinois Energy was different from other companies. We were able to view different options and discuss financing options. Our installer was prompt, polite, and efficient. He was very respectful of the house making sure to protect our floors while he worked. The end result so gorgeous compared to the eye sore I had before! We'll definitely be coming back to Illinois Energy for future work!

Front Door Replacement

Bret B.

We recently had our front door replaced. We had a great experience from the initial sales to the installation. We had previous quotes from another local company, that we had used in the past, and Illinois Energy Windows and Siding not only outbid them significantly, but also offered a better customer experience. We highly recommend them!

Entire House Window and Sliding Door Replacement

Chris L.

We recently had all our windows, sliding door, and escape window replaced. The sales manager was very polite and upfront. The installation went smoothly and only took one day. We love the look it has given our house. We highly recommend Illinois Energy to anyone in the market.

We replaced all of our upstairs windows with Illinois Energy.

Gloria J.

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.

I could not be happier. I love our new siding.

Mr. M.

The color and the contrasting white trim and cornerposts are very nice looking. My wife is excited for the new shutters to be installed to complete the job.
