Door Installation

Sharon B.

I purchased a new exterior back door with screen door. The salesman was very helpful and knowledgeable. The office staff was professional. The installation team did an excellent job. I am very pleased with the entire experience and would recommend Illinois Energy.

We love our new front door

Sharon K.

We had our door installed in the dead of winter. Brr.....but the guys that came for the install were professional, considerate, and freaky fast! So happy we decided to invest in our new door, no longer will I need to worry about ice forming on the inside of our door. This door is well insulated.

French Doors

Jon B.

The salesman came over and showed us all of our options and they were all great. They came on time to install the French doors and did an amazing job. Cleaned up their mess like they weren't even there. There used to be a bad draft, but now I don't feel a thing of air which makes my heating a lot easier. I will be hiring them to do all my windows and back door soon.

Experience with IEWS

BRIAN J.

From our first interaction with IEWS we experienced a genuine, honest, concerned and professional relationship. Attention to detail was especially key through the whole process until final clean up. I would highly recommend this company if you are looking for an integral partner who you can trust to do a fantastic job!

Window installation

They did a fantastic job. They were on time and did the installation of a new picture window for me. The guys were very nice, they did the installation in a timely manner under the time they had extimated. They cleaned up after themselves, took the old window with them and even washed the window inside and out!! I was very pleased with the absolutely wonderful job they did!!

Excellent Company

Anna M.

Love my new windows. The windows are a great quality unlike the Pella windows I had that were rotting. The company made the process very easy and they were very professional! Would use them again.

Patio door replacement

Joseph C.

The whole process was easy and kept us updated on timing for installation. Our patio door was replaced due to cold/heat entering throughout. once replaced the outside noise from the main street was a lot quieter!

Excellent service

Ali S.

We had a great experience using Illinois Energy for our sliding glass back door. The installers came on a very cold day and worked quickly to install the new door. As soon as the door was up, we could no longer feel the cold air coming through the door like our old one. By the time we were done admiring it, the crew had everything cleaned up and framed off. We will definitely be using them again for future projects.
