Summerville's Marine Welding Experts

BUILT FOR THE LOWCOUNTRY. FORGED TO LAST.

Blackwater Welding and Fabrication was built to serve the unique demands of the Charleston Lowcountry — where saltwater, humidity, and weather test every joint and every weld. We specialize in marine-grade welding for boats, docks, trailers, and waterfront structures that need to hold up in the toughest environment on the coast.

Every project we take on — from a custom aluminum dock railing to a full structural steel repair — gets the same treatment: precision fitting, certified welds, and a finish that’s built to outlast the tide. We’re a local Summerville shop with a reputation for showing up on time, welding it right, and standing behind our work.

What We Do

MARINE-GRADE METALWORK

From precision aluminum fabrication to heavy structural steel repairs — we weld the Lowcountry’s most demanding jobs.

Marine Welding & Repairs

Saltwater doesn’t forgive bad welds. We use marine-grade materials and certified techniques to repair, reinforce, and build waterfront structures that stand up to the Lowcountry’s corrosive environment — from boat hulls to dock pilings.

  • Boat hull and deck plate repairs
  • Dock and pier structural welding
  • Aluminum and stainless marine fittings
  • Trailer fabrication and repair
  • Underwater and wet welding capabilities

Structural reinforcements, cleat replacements, and aluminum dock accessories.

Trailer Fab

Boat and equipment trailers built, repaired, and customized for marine environments.

Marine Certification

AWS-certified welds meet commercial and insurance-grade standards.

Custom Metal Fabrication

Have a design in mind? We fabricate custom metalwork in aluminum, stainless steel, and mild steel — from ornamental gates and railings to one-off industrial parts. We work from your sketches, CAD files, or our own field measurements.

Structural Steel & On-Site Welding

Not every project fits in a shop. We bring our rig to your site — job sites, marinas, residential properties, and commercial developments. Structural steel repairs, reinforcement, and custom installs done on location with the same standard of quality.

  • On-site mobile welding service
  • Steel beam and column repairs
  • Commercial and industrial metalwork
  • Custom brackets, supports, and anchors

From handrails to mezzanines — commercial-grade fabrication and installation.

We serve Summerville, Charleston, Mount Pleasant, and the entire Lowcountry.

What Clients Say

WELDED WITH INTEGRITY

Don’t take our word for it — here’s what Lowcountry boat owners and contractors have to say.

“Had them repair a cracked weld on my boat trailer and reinforce the dock cleats at the same time. Fast turnaround, clean beads, and the price was fair. These guys know marine work.”

David M. Summerville, SC

“We needed a custom aluminum handrail for a waterfront deck. They came out, measured everything on-site, fabricated it in the shop, and installed it in one day. Looks incredible — exactly what we wanted.”

Sarah K. Charleston, SC

“I run a commercial fishing operation out of McClellanville. Blackwater has welded everything from my boat railings to the steel frame on my dock hoist. Never had a weld fail. That’s trust you can’t buy.”

Captain Ray T. McClellanville, SC

“Called them for an emergency gate repair on a Saturday. They showed up within two hours, welded it back together, and charged less than I expected. Real stand-up operation — I recommend them to everyone.”
