Great experience

Thomas O.

The initial sales guy was very friendly and helpful. The installation guys showed up right on time as planned. They even went out of their way to clean up additional stuff that they didn't cause (we are redoing our whole basement). And the basement windows look amazing

No more noise

Z M.

The installers were prompt and professional. The installation was quick, and I was even able to continue to work from home without any disruption. I love my windows as I noticed they have blocked out a lot of noise. I have a quieter and cooler house.

Amazing work!

Maria H.

The installers were absolutely amazing!!!! They went above and beyond! They moved my Gazebo enough to make sure the storm door wouldn’t hit it when opened! They cleaned up all the mess and were quick at getting it all done! So very polite and kind.

Great Job

Marcela S.

I had six windows replaced at my home and I couldn’t be happier!! I was fortunate to have a great sales person ( Sean). He explained and made sure the whole process went smoothly. The installation crew was also very professional. I’m very happy with the results, I highly recommend it.

Great experience from a great group of people

Russell Y.

Front to back, the experience with Illnois Energy was wonderful. Our sales rep was considerate and kind (we had the kids running around like crazies). he was not pushy, and offered really great options that fell inside our budget. Installation was FAST, and the installers were very considerate of my home. It was really a wonderful experience, and one that we will seek out again for further work on our house!
