“We recently had our windows replaced by DuPage Window Co and couldn’t be happier with the results. The installers were professional, punctual, and extremely respectful of our home. They worked efficiently, kept the work area clean, and paid great attention to detail. The quality of the installation exceeded our expectations — everything looks fantastic and functions perfectly. So happy with our new windows!”
