At Olson Windows, Doors, Siding & Roofing, quality isn’t negotiable – it’s how we started, how we’ve grown, and how we continue to serve homeowners throughout the communities we serve.
Our story begins in the early 1970s, when Brian Olson began installing roofs and windows by hand, learning the trade from the ground up. Not long after, his brother Scott joined him. Together, they built their reputation the old-fashioned way: by doing the job right, treating homeowners with respect, and growing carefully.
By 1979, that commitment became Olson Windows. From the very beginning, Brian and Scott focused on quality installation and conservative, intentional growth. Their dedication paid off as they became trusted window, door, siding, and roofing specialists throughout the Chicagoland area.

Growing With Purpose & Staying Local
Rather than expanding too quickly, Olson Windows grew thoughtfully. What began as a small rented office eventually became the Barrington, Illinois showroom you’ll find today at 310 W. Northwest Highway. Years later, a second location opened in Warrenville, allowing the team to better serve homeowners across Chicagoland.
For more than 30 years, Olson Windows has remained family-owned and operated, rooted in the community we serve. That local presence matters, it means we understand the homes, the climate, and the expectations of our neighbors because they’re the same expectations we’d have for our own homes.
Built on Experience. Known for Quality.
Long before awards and certifications entered the picture, the Olson brothers were already mastering window installation and replacement. Today, that legacy continues through a team of:
- Superior window installers
- Experienced siding and roofing professionals
- Certified window technicians
Every project is approached from the homeowner’s perspective, with a no-pressure sales process and a collaborative, transparent roadmap from start to finish.
That approach has earned Olson Windows numerous industry recognitions and affiliations, including Angie’s List Super Service Awards, Pella Platinum Elite status, Lindsay Diamond Level Dealer, LP SmartSide Master Preferred Contractor, and more. But what matters most to us is the thousands of satisfied customers who trust us with their homes.
