Rust eats hulls.
Saltwater never sleeps. Pinholes become leaks. Leaks become haul-outs.

What we weld
Three lines. One crew.
Marine, structural and residential — same certified welders, same shop in Ballard, same standard on every bead.
Marine
Saltwater-grade welding on the Puget Sound.
Ship repair and maintenance, custom fabrication for boats and docks, corrosion-built technique, and on-site welding at your slip or yard.
Marine work isn't shop work. Saltwater finds every pinhole. Every spec below is what we actually do.
02
Dock & Boat Fabrication
Custom steel dock frames, gangways, ladders and boat structures built for constant marine exposure and tide cycling.

“Tirso and his crew cut out and replaced a corroded section on my 38ft trawler in under a week. Clean welds, matched filler, pressure-tested. Boat was back in the water before the weekend. Bilingual, hands-on — the way marine work should be done.”

The crew
A small shop that takes the work the big yards won't.
The Fabricator is a hands-on marine welding crew working out of Ballard. We're not a NAVSEA-scale yard and we don't pretend to be — we're the people boat owners, marinas and small contractors call when a job is too small, too urgent, or too specific for the big shops.
The crew is bilingual (English and Spanish), the rig is mobile, and everything that leaves our shop is welded by a real human who's been doing this on Puget Sound water for years. No subcontracting, no surprises.
We're a small, bilingual team that handles the honest jobs — hulls, docks, anodes, aluminum. We show up at your slip, work clean, and leave your boat ready to go back in the water.
How we work
Three steps. Marked like draft.
Numbers below are stacked like draft marks on a hull — depth at the waterline. Same idea here: every step is at a known depth, no surprises.
