About Waterloo Products
Decades of experience building quality structures for families and businesses across the mid-Atlantic region.
Meet Marvin Zook
Marvin Zook grew up around sheds. He worked at Stoltzfus Structures, learning the business from the ground up. Eventually, Marvin and his father Paul Zook started Waterloo Structures — building and selling quality sheds and garages out of Parkesburg, PA. They later sold the business to Stoltzfus Structures, but Marvin's passion for the industry never stopped.
Today, he continues doing what he knows best — helping customers find the right shed, garage, or outdoor structure at a fair price.
Whether you need a compact garden shed or a full-size two-car garage, Marvin is here to walk you through the options and make sure you get exactly what you need — no pressure, no gimmicks.
“I grew up in this industry and it is all I know. My goal is simple — help people find the right structure at a fair price, and make sure it is built to last.”
— Marvin Zook, Founder
