Valves, Thru-Hulls & Seacocks 

Sealed properly. Bonded correctly. One point of contact from inspection to launch. 

Shipyard Services

Every thru-hull is a hole in your boat — and a failed valve or seized seacock below the waterline is a sinking risk, not an inconvenience. Miami Marine services, replaces, and bonds valves, thru-hulls, and seacocks in Miami during haul-out, so every hull penetration opens, closes, and seals the way it should.

What’s Included

  • Inspection of all valves, thru-hulls, and seacocks
  • Replacement with Guidi or Groco hardware
  • Seizing, corrosion, and leak diagnosis
  • Bonding — connecting cables internally to prevent corrosion damage
  • Cycle testing of every ball valve
  • Backing plate and sealing inspection
  • Documentation of all below-waterline fittings
