Established in 1979, Olson Windows, Doors, & Siding is a family-owned and operated company nestled in the northwest Chicago suburbs. The story began when Brian Olson started installing roofs and windows in the early 70’s, followed shortly thereafter by his brother Scott. They focused on quality installation and conservative growth for many years and slowly built a name for themselves as windows, siding and roofing specialists in the Barrington area.
With a conservative approach they acquired more window retail space, turning a rented small office into the current Barrington, IL showroom location you’d find today at 310 W. Northwest Hwy. Several years later they expanded into a second location in Warrenville, IL.
