A Note From Our Founders

Legacy Sealants is the culmination of everything we’ve learned—starting with our roots at OSI, the company our family founded in 1966 and helped grow into a trusted name among professional contractors.

After spending time building businesses outside the siding and window space, we’ve returned to our foundation with a fresh approach:

Legacy Pro™ — Performance Delivered Direct ™.

We are proud to bring you a product line built on real-world experience, jobsite-tested performance, and direct-to-user value. Whether you're an independent contractor, construction company, or a hands-on DIYer, Legacy Pro was designed with you in mind—delivering the quality you expect without the middleman markup.

Thanks for your trust,

– Pete & Mark Longo

Co-Founders,
Legacy Sealants, Inc.
