About Us

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.

Over the past 30+ years Brian and Scott have built a base of superior window installers, experienced siding, roofing professionals and certified window technicians that approach replacement projects with the homeowner’s perspective in mind. The team’s quality of installation, no-pressure sales process and collaboration style have won them several awards and affiliations (Angies List Super-Service, BBB A+, Pella Platinum, PSC, and more), and more importantly, thousands of satisfied customers throughout Chicagoland.

For the homeowner looking for a local, knowledgeable partner in the exterior renovation process Olson Windows offers a thorough and personalized roadmap of your replacement project that is delivered with the transparency, courtesy and detail we’d expect for service on our own homes.

Olson Windows installers have experience with the best siding, doors, roofing and windows manufacturers’ products because we know every customer has different needs.

Our Customers Have Great Things to Say

“I contacted five window/door companies when I looked for replacement patio door in August, finally I decided to go with Olson, not only they offered competitive price, salesman Tony’s professionalism was one of the main reasons for my decision. Tony was very helpful along the way, he returned my phone calls/emails quickly, always tried his best to meet my expectation. I am so happy to work with Tony/Olson for this project, will strongly recommend to my friends for their window/door project.

Many thanks to Tony and Olson for their outstanding job!”
