I researched the Internet to find a company that would provide high quality at a fair price. I was familiar with the names like Pella and Anderson, but when I spent time comparing them all, Illinois Energy came out on top. I had never heard of them before but they have been a reliable, high quality provider of windows and doors for quite some time. Their ratings were high and I liked the quality, and the lifetime warranty, and the fact that they had their own installers. They came and installed 5 windows and 1 patio door in one day. They were a well-oiled machine. Several workers came and they were clean, efficient did great work. I was very impressed and plan on having them come back next year to install another six windows.
