Dock Repair in Wexford, Hilton Head Island
Wexford keeps its own private lock off Broad Creek, holding the harbour at one level while the creek outside it keeps swinging with the tide.
What makes marine work in Wexford different?
Wexford operates its own private lock, so the harbour sits at a controlled level while Broad Creek outside swings with the tide. Docks and lifts inside can be built to a fixed waterline, and the bulkheads that ring the harbour hold back a static head of water rather than a cycling one.

What Wexford's lock changes about a dock
Wexford operates its own private lock, so the harbour inside sits at a controlled, static water level while Broad Creek immediately outside continues to swing with the tide. Docks and lifts built inside the lock are designed to that one fixed elevation rather than to Broad Creek's own tidal range.
This puts Wexford in the same category as Windmill Harbour rather than with the island's open tidal frontage — a dock built for Wexford's harbour and a dock built for unlocked Broad Creek frontage a short distance away are engineered around genuinely different water conditions.
The lock itself is also part of what defines the harbour's boundary for permitting purposes — work inside it is reviewed against the harbour's controlled conditions, while any structure a property might have on the Broad Creek side, outside the lock, is reviewed against the creek's own tidal range instead.
Building bulkheads against a static head of water
Bulkheads ringing Wexford's harbour hold back a static head of water rather than a cycling tidal one, which changes the load profile a wall has to resist — steady pressure at one consistent level, instead of load that varies through the day as the tide moves.
Tie-back and drainage design still matter as much as they do on any bulkhead, but the engineering is solving for constant hydrostatic pressure at a known level rather than for the added complexity of a structure that's submerged, then exposed, twice a day.
A static water level also means a leaning wall or a washout doesn't announce itself with the same visual cues a cycling tidal wall would show at low water — inspection inside the harbour has to be as deliberate as it is anywhere else on a controlled-level waterway.
Dock and lift work inside the harbour
Docks and lifts inside Wexford's harbour are built and sized to the lock's fixed water level, similar to Windmill Harbour — fixed pierheads at a predictable elevation, and lift travel calculated for a known level rather than for tidal swing.
Piling work below that fixed waterline still contends with the same pluff mud and marine-borer conditions found elsewhere on the island; the lock changes the water-level engineering, not the below-mudline conditions a piling has to be set into.
Boat lifts inside the harbour follow the same open-sided, no-enclosure standard required island-wide, and sizing still runs on the boat's loaded weight — the lock simplifies the travel calculation by removing tidal swing from the equation, but capacity is worked out the same way it would be anywhere else.
Working inside the gate: architectural review and scheduling
Work inside Wexford's gate runs on the community's own access rules and scheduling in addition to the harbour lock's own operation, and dock or bulkhead projects go through Wexford's property owners' association and architectural review alongside SCDES Critical Area review.
We coordinate the community submission, the state permit, and access scheduling as one package, the same approach used across every gated community on the island.
Material and equipment delivery into the harbour follows the lock's own schedule rather than the tide-driven access used on open frontage, which is a planning detail worth building into a project timeline from the outset rather than discovering once a crew is ready to start.
