Sliding Patio Door
As usual, Illinois Energy provided a great product and customer service. I've used them for years and they never disappoint. From their friendly staff, to top of the line warranty, you will not be disappointed either.
Excellent company to work with - excellent window!
Illinois Energy was a great company to work with. Everyone from the estimator, to office personnel and installers were professional, on-time and knowledgeable. Installers did an great job and were meticulous in their installation and cleanup. We could not be happier with the windows or with this company. Thank you for a job extremely well done!
Window replacement
Had a great experience from beginning to end! We signed the contract on the day we had our quote because we were sold! The guy we talked to was so easy to get along with and made the process seamless. The installer men were very professional and they were finished within 6 hours with just 2 guys, very impressive. There was a small problem after install but the office ladies I spoke with were so kind and understanding and had a service guy out within 24 hours of my phone call. We are amazed with the work and are so happy to have done business with Illinois energy
Door Installation
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
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
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
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!!
New Window Installation
Had a great overall experience with Illinois Energy, from the time we talked to the salesman to the install itself. Everyone was knowledgeable, professional, on-time and friendly. Also there prices are hard to beat. I would definitely recommend them and look forward to doing business with them in the future.
Excellent Company
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.
