Window Installation
Very friendly, not pushy with sales, I feel like I got a good deal for the product and everything went smoothly. The installers were quick and efficient.
Highly Recommended
From start to finish, Illinois Energy did a great job. The sales rep clearly explained the product, which was custom made in a timely manner. The installation crew completed the work in less than a day and cleaned up both inside and outside the house. The office followed up a with a call to make certain were satisfied with the work. I highly recommend this company.
Great service and product!
I would highly recommend IL Windows & Siding for your door replacement needs. We recently needed our outdated front door replaced. From our initial consultation to the actual install day, the service we received was amazing. Everyone was courteous, knowledgeable about the product and pricing was very competitive. It was an overall smooth process. Plus, receive a ton of compliments on our new door!
Sliding Door Replacement
I am very pleased with the service that I received from Illinois Energy. While the cost was not the lowest the quality of materials as well as the lifetime warranty, which is transferable, were major factors that I took into consideration when deciding to go with them. I was quoted that it would take 10-20 weeks for the door to arrive and they were ready to install the door right at 10 weeks. They worked with the city to get all the permits needed and provided me all the information so that I could get the approval through my HOA. They were very professional and worked with my schedule to find the best time to get the door installed. The team that came to install my door were very respectful and performed quality work. The took the time to make sure that everything was correct and then cleaned up all the debris that was left from the removal of the old door and the installation of the new door. The door itself is very nice and slides with the greatest of ease.
Repeat Customers
We recently had a 60"x60" picture window installed, as well as two double-hung windows. The installation team was friendly and efficient, and the windows look wonderful. We are repeat customers and highly recommend Illinois Energy! -Mary & John Henderson
So happy, new windows.
This company literally takes first prize with customer service, product quality, professional installation and ease of process. Every phase of my experience was seamless. I have more window replacements planned next year and I will look no further than Illinois Energy. Superior company that keeps their promise. Thank you Illinois Energy Team!
