A Note From Our Founders

Origin Pro Sealants is the continuation of a family story that began in 1966 with OSI – a brand our family helped build into a trusted name among professional contractors.

After years leading companies across the building materials industry, we’ve returned to our roots with a renewed focus on what matters most: delivering performance that stands up to real jobsite conditions.

With Origin Pro™, our commitment is simple:

Professional-grade products, engineered from real-world experience, delivered direct without the middleman markup.

Whether you’re a contractor, builder, or project manager, Legacy Pro was created to give you reliable performance, trusted quality, and a smarter way to buy.

Thanks for your trust,
