We contacted IL Energy because a previous homeowner used the company in the past and were very satisfied. We are so glad we did. We had 2 sliding windows replaced and the new front windows look great. We appreciate the time and effort staff took to help us select the right windows. Our sales rep was so knowledgeable about the product and company warranty. Staff was easy to talk to and access by phone. They worked with us to accommodate our schedule and determine the best date of installation. It was a warm day, but staff worked tirelessly with great skill and courtesy. We would highly recommend IL Energy.
