Lowcountry Marine Construction Since 1990

Docks, floating systems, seawalls, and waterfront structures built for the way the Lowcountry actually works.

Welcome to Docks Unlimited

Mount Pleasant, Charleston SC and the Lowcountry’s most trusted name in dock construction, seawall protection, and marine access systems.

We build every structure in-shop, bolt it together on-site, and finish it to match the coast it serves. From aluminum-framed walkways and floating docks to structural seawalls and ADA-access gangways, our systems are designed to last — not just look good.

Every Docks Unlimited project includes Sea Power Marine Products, full permitting coordination, and the kind of structural details most builders don’t even mention. Because we don’t just build docks. We build what other docks wish they were. We handle all permitting from SCDHEC to Army Corps to HOAs.

Trusted by the Lowcountry’s Most Demanding Properties

We don't just build residential docks; we engineer commercial and community marine structures that are built to take a beating. Our footprint includes:

Daniel Island: Over two decades of continuous marine construction, seawalls, and custom timber bridges for private residences and community developments.
Bishop Gadsden: Custom commercial aluminum bridges, viewing platforms, and heavy-duty timber roof structures.
Wando River Marina: Phased installation of heavy-duty commercial aluminum floating docks, internal pile guides, and gas dock facilities.
Wild Dunes: High-impact coastal dune crossovers, ADA access ramps, and custom seawalls engineered for extreme coastal environments.

We build docks three different ways

Traditional timber

Heavy timber.

Complete aluminum systems

Complete aluminum systems: The marine-grade aluminum acts as the structural skeleton, while the decking acts as the body. This delivers commercial-grade durability underneath—rated to 100 pounds per square foot—while maintaining a traditional Lowcountry look on the outside.

Each system can be used to build a complete dock. Every project is based on the property, the conditions, and how it will be used.

We do not build every dock the same way.

We evaluate the site, the water, the marsh, access, and how the dock will be used. Then we build the system that fits the job.

Sea Power Marine Products & HDPE Pile Covers

Used in our projects and across the industry, we proudly source our materials from Sea Power Marine Products, an independent manufacturer of advanced marine hardware. Their heavy-duty HDPE piling covers fix the problem at the piling, protecting your foundation from marine borers and tidal impact so your dock is built for the long haul.

Permitting & Process

Dock permitting in South Carolina is a multi-agency process involving state, federal, and environmental review. We manage that process from start to finish alongside specialized regulatory partners.

Teardown and install were completed by water with no land disturbance.
Fast, durable, beautiful.
