Absolutely Would Work with Again!

Cathey N.

We needed our original 60-year-old back door replaced, the salesperson was very professional and patiently answered all of our questions. There was no pressure to buy and it never felt like he was in a hurry to make a sale and get out of there. We were confident, after this meeting, that Illinois Energy was the company we wanted. The salesperson was honest that it could take 6-10 weeks for the new door to be manufactured and installed. At one point, it seemed it was more than that, but we were just excited to get our new door. It only took 5 weeks! The installers were professional and really knew their stuff. They were very kind and courteous and got the job done in about 3 hours. We have a storm door that was new and didn't want to replace it. To be honest, we were a little worried that it may have gotten damaged when they were removing and reinstalling it, but, in the end, what put me over the top was that they reinstalled it perfectly AND re-caulked around the frame of the storm door at the house. It is so beautiful! The next day there was absolutely no buyer's remorse and we are still so happy that we chose Illinois Energy to replace our back door. We will definitely work with Illinois Energy again for our front door and windows in the near future.

Extremely professional company

Rinkal P.

We love our new real good quality patio door. We actually got the door installed much earlier than the expected date. Extremely professional folks! I would recommend the company to all my friends and family.

Looks Like a New Home

Melissa P.

We had a great experience working with Illinois Energy. The sales consultant spent the morning with us discussing the most cost and energy efficient windows for each room of our home. There was no pressure to upgrade or spend on additional features. We were shown a portfolio of nearby homes and competitive prices to help us make an informed decision. The office was in frequent contact with us prior to installation to ensure it went smoothly. Installation was completed in one day, and the installers were professional and courteous. The windows have been a great improvement to the look of our home, along with providing much better insulation and outside noise reduction. We would certainly recommend Illinois Energy to anyone else looking to replace their windows!

Window Replacement

Amy W.

We worked with Illinois Energy for new windows. The order process was easy and we financed with them instead of having to take out a home equity loan. Our windows were ready 2 weeks earlier than promised so that was a nice surprise and the installation was completed timely.

Window replacement of two rotten windows.

Dean B.

I was in need of having 2 large rotten windows replaced. Now how to choose a window replacement company? I've seen all the TV commercials for various providers. I was concerned about the installation as there was some rotten wood. I eventually selected Illinois Energy Windows, as the installer are not subcontractors. They were also able to configure a custom window that works better but still met the home owners assoc. requirements. Upon arrival the installer laid tarps all the way to where the windows would be installed. The installation went smooth and they actually cleaned up after. Check them out.

Double Hung (68×46) Windows

Michael B.

Illinois Energy is a top-flight company! They were on top of it from the moment we called them to inquire about our large windows (68” x 46”). We had three-to-four companies come through our home with the same spiel but Illinois Energy had a good price (somewhere in the middle) and had a warranty that was above-and-beyond better than all the competition. We were able to haggle a little to get to a price that worked for both parties. When the day came to have the windows installed, the contractors were quick and efficient. It looks as if the windows were always there. They cleaned up and overall did a fantastic job. I would highly recommend this company and would definitely use them again in the future.

Awesome windows

Danny R.

I'm very happy with new windows and easy to open to clean it while inside the house. Better than using ladder to climb up to second floor to clean old windows.
