Repeat Customer!!

Rick H.

This is the 2nd time we have used them, originally in 1994! Just as before their response time is impeccable and the appointment happened as quickly as wanted. We did do our due diligence - just double checking since so many years went by and once again they were the obvious choice. We know we can count on them for reasonable pricing and fantastic service! Great job once again!

Great Experience, Great Windows

Amanda T.

My husband and I had a wonderful experience with Illinois Energy! They met with us and explained all our options and gave us plenty of information about the windows they provide and how the installation would work. The day of the installation, they were professional, quick, and did a beautiful job with our windows. We would highly recommend them to anyone thinking about new windows.

Happy Customers

Michelle S.

We recently had a fantastic experience with Illinois Energy for our new door installation. Choosing our door with the sales representative was simple, informative, and seamless. They took the time to guide us through the options, making the whole process stress-free. The installation was excellent – high-quality work that truly stands out, and our new door looks amazing. We couldn’t be happier with the results. We will definitely be using Illinois Energy again when it’s time to update our front doors. Highly recommend them for anyone looking for top-notch service and craftsmanship!

New Windows

Luis D.

We purchased windows for our house and the process was very easy. The entire staff was great to work with from signing the documents to completing the installation. The crew was terrific. They treated our house as their own, cleaning up everything both inside and out. The crew even had to contend with one of the window openings needing to be adjusted for size. They crafted a new fitting complete with new casing and even painted it with the paint we had. We would highly recommend them.
