Legacy Pro was born from a renewed partnership between brothers with deep roots in the sealant industry.

The Longo family legacy began with their dad and uncle in 1966. With over 60 combined years of experience in siding & window professional-grade sealants, we’ve led with innovation and built a reputation for trust and performance. Legacy Pro is our next chapter: a direct-to-contractor and DIYer e-commerce platform delivering high-performance 100% silicone and Hybrid MS-polymer sealants — straight to your jobsite or doorstep. Our mission is simple: Bring professional-grade quality at a cost savings directly to the end-user.

Performance Delivered Direct.
