15+ years of hands-on coating and waterproofing experience • San Diego County
From precision surface prep (grinding) to high-end decorative finishes, we deliver waterproofing and coating systems that look incredible and perform for years.
I'm Miguel Saldana, founder of Coastal Build & Design. With 15+ years in waterproofing and resin coating systems, I build projects the right way—starting with proper prep, correct system selection, and finishing with clean, design-forward detail.
If you want a surface that's beautiful today and durable tomorrow, you're in the right place.
A premium finish isn't luck. It's process. We don't coat over problems—we grind, profile, repair, and build the right system for your surface and exposure. Then we deliver a finish that elevates the space with a modern, luxury look.
