Crocker Marine Services designs, builds, and repairs docks, seawalls, and boat lifts throughout Cape Coral, Florida, in Lee County. Cape Coral's 400-plus miles of canals — more than any other city in the world — split into Gulf-access waterways that reach the Caloosahatchee River and the freshwater canals north of the weir system. Which one your home sits on changes what you can build, how deep the water stays, and what the city will permit. We work on both, and we keep an office on Cape Coral Parkway.
Marine construction services in Cape Coral
Crocker Marine is a full-service marine contractor — we handle every part of a Cape Coral waterfront project in-house, from the first survey to the final inspection. See the full range of services, or browse completed dock, seawall, and lift projects across Southwest Florida.
Docks
We build custom fixed and floating docks sized to your lot, your vessel, and your canal's width and clearance. Cape Coral's warm, brackish canal water keeps marine borers active year-round and is hard on untreated wood, so we build with materials chosen for a saltwater environment and detail the piling connections for the city's soft, sandy soil. Services include new dock installation, dock repair, full dock replacement, dock accessories — ladders, piling caps, cleats, and lighting — and dock canopies and shade covers to keep sun and rain off the boat.
Seawalls
Nearly every waterfront lot in Cape Coral is held by a seawall, and the concrete walls installed during the city's early build-out are now reaching the end of a typical 30-to-50-year service life. We install and replace both poured-concrete and vinyl sheet-pile seawalls, and we build to the City of Cape Coral's current seawall specifications. Where a wall is still sound, seawall repair and seawall maintenance — tie-backs, cap repair, filling voids behind the panel — can add years before a full seawall replacement or new installation is needed.
Boat lifts
We install and service boat lifts for everything from a jet ski to a large cruiser, working with Coastal Boat Lifts, which builds its lifts in Fort Myers for Southwest Florida conditions. On a Gulf-access canal we size the lift to your vessel and the mean low-water depth; on a freshwater canal, water level is steadier but still needs checking before the beams are set. We also handle boat lift repair — cables, motors, bunks, and remote systems.
Dredging
Cape Coral's Gulf-access canals — especially the older ones off the Caloosahatchee and near the spreader system — shoal in over time, and a dock or boat lift is little use if the vessel can't float to it at low tide. Our residential dredging service restores a canal or slip to its permitted design depth, with the state and county permitting handled as part of the job. Dredging is often scheduled alongside a new dock or lift so the access matches the structure.
Marine inspections
If you're buying or selling a Cape Coral waterfront home, or renewing insurance on one, a documented condition report on the dock, seawall, and boat lift protects the deal. Our marine inspections cover structural condition, remaining service life, code and permit status, and the repairs a property will need — in writing, with photos. Many buyers add one to the standard home inspection because a failing seawall is a five- or six-figure surprise.
Permits and local conditions in Cape Coral
Marine construction in Cape Coral is permitted through the City of Cape Coral, with Lee County and, for work below the mean high-water line, the Florida Department of Environmental Protection and the U.S. Army Corps of Engineers also involved. A seawall or dock permit in the city generally needs a survey and a set of drawings; we prepare and submit these as part of the project.
A few conditions specific to Cape Coral shape almost every job here:
- Gulf-access vs. freshwater canals. Homes south and west of the Chiquita Lock and the city's weir system have tidal, Gulf-access water; canals north of it are freshwater and hold a near-constant level. This affects dredging need, lift sizing, and how a seawall is loaded.
- Canal depth. Many Gulf-access canals — especially the older ones off the river — have silted in and sit shallow at low tide, which is why dredging is a common part of a dock or lift project here.
- Soil and limestone. Cape Coral's sandy soil over a limestone base can let voids form behind a seawall and allow pilings to settle, so anchoring and backfill detail matter more than they do on firmer ground.
- Storm exposure. Hurricane Ian pushed a significant surge up the canal system in 2022; a lot of current seawall and dock work in the city is storm-driven replacement.

Cape Coral marine construction FAQ
Do I need a permit to build or replace a dock in Cape Coral?
Yes. Dock and seawall work in Cape Coral requires a city permit, usually with a current survey and drawings, and work below the high-water line also needs state and federal sign-off. We handle the permitting as part of the project.
What's the difference between a Gulf-access and a freshwater canal home?
Gulf-access canals connect — directly or through the Chiquita Lock — to the Caloosahatchee River and the Gulf, so the water is tidal and salty. Freshwater canals north of the weir system hold a steady level and don't reach open water by boat. It affects dredging, seawall load, boat lift sizing, and resale value.
How long does a concrete seawall last in Cape Coral?
Typically 30 to 50 years, depending on the original construction and the soil behind it. Many walls in the older parts of the city are now at or past that range, which is why replacement is common here.
Can I put a boat lift on a freshwater canal?
Yes. Freshwater canals actually make lift sizing simpler because the water level barely moves — but the lift still has to match the vessel weight and the seawall or dock it mounts to.
My canal is too shallow at low tide. Can that be fixed?
Often, yes, through permitted dredging to restore the original design depth. We assess whether the shoaling is on your property or in a shared section of the canal, which changes the permit path.
Should I get a marine inspection before buying a Cape Coral waterfront home?
It's worth it. A standard home inspection rarely covers the seawall, dock, or boat lift in any depth, and those are the most expensive things to fix on a canal property. A marine inspection gives you a written condition report and repair estimate before you close.
Do you work on both sides of the Chiquita Lock?
Yes — we build and repair docks, seawalls, and lifts throughout Cape Coral, on Gulf-access and freshwater canals alike. Request a free estimate or call (239) 841-9674.
