IL Energy installed our new patio door in under 4 hours! I can't imagine having to do this project myself, would have taken 4 weeks! The sales team was great to work with, amazing communication. I was very impressed with the install team. They quickly identified an issue with the install and were able to adapt onsite to address the issue. I would highly recommend using IL Energy for your next project!

We had 5 windows and a sliding glass door installed and we couldn't be happier! I keep saying "we have the Cadillac of windows" and they defiantly are with their quality. The windows frame my backyard perfectly! They were fairly large so we were nervous but they are stunning and you can feel zero heat transfer inside! They are trimmed out beautifully too! They'll be so easy to clean with the folding-in function and the child lock is very helpful with my 7 month old who is messing with everything. The sliding glass door I can... read more

We have worked with IL Energy three times now, all have exceeded our expectations. We had all the windows on our first floor and a couple basement windows replaced 4 years ago. The windows are beautiful and the work was amazing. Highly impressed they did all the work in 1 day. We then had the company out again to replace our gutters, fascia, and soffit. When my husband wanted a bigger slope on the gutters after install, they fixed it with ease and no cost to us. Then just this week they came out again to replace two more bas... read more

Second time using this company. The installers took their time. They both were very considerate of our home both inside and out. They worked very clean. They even assisted taking down an old awning that was above our new picture window.

I have had several windows installed over the years. Everyone is friendly and professional. We love the windows. There is absolutely no draft and love the way they open and close smoothly.

Second time using this company. Quality service, installation and products. Had a full front door system with side windows installed last year and a back door with storm door this year. Those fiberglass doors don’t even let a wisp of wind in.....toasty free winter.... will use them again and again. Nice 18 month same as cash financing.

Illinois Energy replaced my Bay Window, Patio Door, 2 very large windows including custom arches and my Front Door. The entire process went very smooth and uneventful. From the initial Sales visit with Garrett, to the installation that finished quickly and smoothly. The installers where professional, respectful, cleaned up after each job. I received follow up calls to make sure I was happy with the results. The windows and doors are beautiful and open with ease. I am receiving many complements on my windows and doors. I high... read more
