service call
I had an issue with my bottom sash window yesterday. (my fault) I called and a service guy came right over within two hours. I wish I got his name. He was so nice! Professional! And, he took the time to explain what I did wrong and how to avoid further problems. It was totally my fault for the issue yet he was Great!! So pleased with customer service and quick response! I can't thank you enough!
Window review
Great customer service and beautiful windows. Nice job installing and clean up ! Second home we used your company for, and are well pleased .
Custom Sliding Door Install
They did a great job on our patio door. The new door glides like an Olympic skater. Installation was pretty quick and quiet and didn't leave a mess. I'd have them back for another project.
Great Company to do business with
I have used Illinois Energy Windows and Siding at my current residence and at my previous residence. I am very happy with this company. The windows are high quality and have helped keep my heating bills down during the winter months. They kept me informed of the installation process. Their installation crew was professional and cleaned up after themselves. Illinois Energy Windows & Siding stands behind their product and has great customer service. I would recommend this company.
Replace window
Fabulous! Our entire experience was great. This is our second project, and everything went very smooth. Top notch service. I can’t say enough good things about them.
Promise kept, 100% happy
I had all my house’s window frames replaced by Illinois Energy and it looks great. Had an issue with one frame but IE stuck to their promise of no payment until I am 100% satisfied and got the problem addressed with great skill and professionalism (thank you Nate and team!) The quality and workmanship is fantastic and I recommend IE hands down.
