We began a project to replace our home's windows in a phased approach starting in 2016. Each of the four experiences was as pleasant as the first. IE offered a one-year same as cash to offset the significant expense all at once. From sales to installation to customer support, the Illinois Energy (IE) team that worked with us was knowledgeable, friendly, and professional. IE stands by its products and installation; any issues, IE will address them straightaway with a follow-up appointment. Best yet, the windows come with a transferable lifetime warranty. No other window company offers that good of a warranty. Now for the product itself; I can not say enough about the quality of Illinois Energy's windows. They are custom constructed by the Amish. The windows are tinted, filtering out the damaging effect of the sun to minimize fading. The windows are sturdy, easy to clean, and aesthetically complement my home's interior and exterior.
