Replacement windows

Replacement Windows Our new windows were custom made for our home by Illinois Energy Windows and Siding recently. A shout out to Savanah and Kaylee in customer service. They are knowledgeble in their respective jobs as well as patient and friendly. Garrett evaluated all our windows and took all the initial measurements. He suggested style and materials. He was easy to talk to, very professional, and had a great sense of humor. A team member came to double check the measurements. He was courteous and experienced in this field. From start to finish, the installers conducted themselves with the utmost professionalism. They arrived on schedule, worked efficiently and demonstrated exceptional attention to detail. We were impressed about how they cleaned up during and after the installation of each window. They went above and beyond what was expected of them. We are happy with our new windows, they look great! We definitely recommend this company to others.

Window replacement review

Jamie B.

Flawless experience. Sales process was straight forward. Installation team was clean and efficient. They replaced 13 windows in less than 2 days. The installation team (direct employees - no subcontractors) kept the house tidy and cleaned everything up. The end result exceeded expectations.

We had our front door replaced. Everyone we talked to was professional and personable. Our installer, Jaromir, was incredible! he was professional and we enjoyed talking with him as well. He did an amazing job installing our front door - by himself! He was quick, did a meticulous job and our new door is amazing!

Great experience

Lana P.

I was completely thrilled with the men who installed our new windows. I have extensive gardens, and they did everything they could to not smash a single plant. They even put up a scaffold to strattle the plants while putting in ground floor windows. This obviously made their job more difficult, but preserved my gardens. (And I didn’t even mention how nervous I was about them destroying my plants.) The windows look great and move smoothly.
