Replacement Windows
We had a positive experience with Illinois Energy installing our replacement windows. The team leader was professional and knowledgeable explaining the process to us. Windows went in with no issues. The windows came with two locks and a safety lock which was a bonus feature for us. They look great and we are very pleased with the results.
Illinois Energy Inc. PatioDoor and Windows Install
Had Illinois Energy Windows and Siding Inc. install a new sliding patio door and a few double-hung windows — really happy with how it turned out. Quality is solid, and the exterior color matches our house perfectly, while the white interior finish looks great with our walls. The crew was professional and considerate — they laid down rugs to protect our floors and covered furniture with plastic before starting. When they finished, they cleaned up completely and left everything looking perfect. Highly recommend if you're looking to get windows or doors done right!
Door Replacement
Illinois Energy replace all are windows five years ago, and just recently they replaced 3 doors and converted a window into a new sliding glass door. We highly recommend Illinois Energy for any window or door project you may have.
EXCEPTIONAL SERVICE
Starting with Paul, our Illinois Energy sales consultant, we were impressed by how well spoken and knowledgeable he was about the products. He walked us through the process, answered our questions, and made sure we understood all our options. We purchased new windows and a patio door, and the team also replaced the trim around our garage door, which had some water damage. The two installers were courteous, professional, and detail oriented. They worked quickly and efficiently, covered all the areas where they were working, and cleaned up after themselves. Overall, it was a positive experience. We are very happy with our new windows and patio door, and their appearance, quality, and energy efficiency are sure to add value to our home. I would recommend this company to anyone looking for a professional, efficient, and high-quality window or patio door installation experience. Tom K.
Hire Illinois Energy
I would not hesitate to hire Illinois Energy again. We have used them several times over the years for entry doors, shutters, and general repairs. Their estimates are honest and fair and the workmanship is exceptional. Very experienced team providing quality products and service.
Great Experience
"I recently had my windows replaced with Illinois Energy Windows & Siding, and I couldn’t be happier with the results! From the first consultation to the final installation, the team was professional, punctual, and respectful of my home. They explained my options clearly, along with the transferrable lifetime warranty, and completed the work on schedule. The crew worked well together. The installation was neat, with no mess left behind, and the new windows have already made my home quieter and more comfortable. I highly recommend them to anyone looking for quality craftsmanship and excellent customer service."
Great service for the second time!
This is my second time using this company for window and door replacement. We have now replaced all of the windows in my home with this great company. They look and work great.
Perfect Door Installation
Illinois Energy replaced our original front door and screen door. The process was seamless from purchase to installation. Our installer did a remarkable job. He was courteous and efficient. A real craftsman-everything he did was as if he was doing this at his own home. When finished, he picked up everything, vacuumed and even washed the entryway floor! My husband I would definitely recommend Illinois Energy for your next door or window project!
