Excellent Communication!

Emily B.

We had our windows replaced last week and the whole experience was smooth and seamless. The process started with a representative coming to our home to discuss our needs and wants. We were put at ease and painted a clear picture of how the whole process works, the quality of the product, timeline, etc. The next day we received a follow up call to answer any further questions. Then the following week a representative was sent out to measure our windows and provide more in-depth knowledge of the product and process. We received a time frame for when the windows would be ready and it was spot on. Within a week of our windows being ready to go, we had the installation team here and working hard. They were detail oriented, respectful, had-working, and cleaned up everything. The new windows are absolutely amazing and we are so happy! I think the best part of this whole experience was the communication. Illinois Energy goes above and beyond making sure you are at ease. Definitely recommend!!!

Great overall experience

Chris P.

Great experience from initial contact to installation. Quality of the door and the installation were top notch. Appreciate the fact that they manufacture and install. Installation isn't outsourced and the quality and attention to detail reflects that.

Excellent Door Installation

Nadi P.

Illinois Energy installed a new back and storm door to our house. Our experience with them from quote to final installation was phenomenal. The sales team was helpful and there was no pushy sales pitch. They cared about what we needed. The price was competitive, everything was completed on time and they checked in multiple times throughout the process including a follow-up call the day after installation to make sure we were satisfied. The installer was friendly and explained each step along the way. He even replaced some rotted wood that he found when removing the old door. After installation he cleaned everything up like he wasn’t even there and then thoroughly explained all of the features of the new doors before leaving our house. Will say this is by far the best experience we’ve had with home repairs in a long time. Thanks Illinois Energy!!

The sales agent was respectful and no-nonsense, the work crew was professional, efficient and respectful of my property. Customer service was easily reachable, understanding and very helpful in resolving any issues that we'd had with the installation. Though one of the more expensive options out there, we definitely got what we paid for; excellent quality.

Front door installation

Ed G.

The entire process from start to finish was handled professionally. Jerry installed the door, he was neat and cleaned up after the installation. He did an exceptionally thorough job and made sure that everything was to our satisfaction. I will recommend Illinois Energy to friends in the future.

Happy we made this choice.

Jerry M.

We chose to call Illinois Energy Windows for a quote on replacing 6 lower level windows after reading the customer reviews. They were very thorough in explaining the manufacture, warranty and installation of the windows. We also appreciated the lack of a hard sell. The installers were professional and the install took less than a day. They did not mind my asking questions and took the time to explain certain steps involved. We were impressed with how clean they left the site, inside and out. They even washed all the new windows. We would highly recommend Illinois Energy to anyone looking for quality window replacements.

The service was outstanding. Prior to instillation they kept us well informed and were flexible with the instillation date. Instillation went very smoothly. The crew was courteous, efficient, answered many questions I had, and cleaned up extrememly well. There was minimum disruption for us. Overall a very good product and servicing. Cost was a little more than I wanted but the lifetime warranty that includes all parts and labor made it worthwhile. And it looks great.

Best door ever

Carl A.

We just got our new Speakeasy door installed today from Illinois Energy Windows and Siding. According to my wife, I was so excited last night that I was sleep-talking about passwords. I can’t wait to host a party or hand out candy to trick-or-treaters on Halloween. Who knew a door could be so much fun! The installers did an awesome job I could not be happier with the whole experience.

Great windows and service

Cindy K.

Garrett Howard did a great job presenting the windows and all the features. The installation crew was very professional. They cleaned up daily. Windows were installed in the timeframe designated. All features of the windows were reviewed after installation and questions were answered politely.
