Crocker Marine Services designs, builds, and repairs docks, seawalls, and boat lifts on Captiva Island, Florida, in unincorporated Lee County. Captiva connects to Sanibel by a short bridge over Blind Pass but has no bridge to the mainland, so it keeps a low-density, low-key character that Lee County's Captiva-specific land-use rules are built to protect. Most waterfront here faces Pine Island Sound; the Gulf side is open beach.

Docks
Sound-side docks on Captiva are more sheltered than the Gulf beach frontage, and most residential waterfront work here is on the Pine Island Sound side. We build new docks and handle repair, replacement, accessories, and canopies and shade covers.
Seawalls
Captiva's sound-front seawalls are a mix of concrete and vinyl, aging the way any coastal Southwest Florida wall does. We install and replace both and keep sound walls going with repair and maintenance before a replacement or new wall.
Boat lifts
We install and service boat lifts from Coastal Boat Lifts in Fort Myers, sized to the vessel and Pine Island Sound's depth. Repair covers cables, motors, bunks, and controls.
Dredging
Sound-side slips can shoal over time. Our residential dredging restores permitted depth, permitting handled — with materials and equipment access coordinated for the island.
Marine inspections
Our marine inspections give buyers, sellers, and insurers a written condition report on the dock, seawall, and lift.
Permits and local conditions on Captiva
Captiva is unincorporated, so marine-construction permits go through Lee County — which applies Captiva-specific land-use standards on top of the county code — along with the Florida Department of Environmental Protection and U.S. Army Corps of Engineers for work below the mean high-water line.
- Island access. No bridge reaches the mainland; equipment and materials move by the Sanibel causeway and then the short Blind Pass bridge, or by barge, which factors into project scheduling.
- Low-density land use. Lee County applies specific standards to protect Captiva's low-key character, which extends to waterfront structures.
- Sound vs. Gulf. Pine Island Sound frontage is sheltered; Gulf-side beach frontage is a different, more exposed environment.
- Storm history. Like the rest of the barrier islands, Captiva has seen significant hurricane impact in recent years, and rebuild work follows current code.

Captiva marine construction FAQ
Does island access make a Captiva project more complicated?
It adds scheduling and logistics considerations — materials and equipment travel via the Sanibel causeway and the Blind Pass bridge — but it's a routine part of building on Captiva, and we plan for it.
Who permits dock and seawall work on Captiva?
Lee County, applying Captiva-specific land-use standards, plus FDEP and the Army Corps for in-water work.
Do you build on the Gulf side as well as the sound side?
Most residential dock and seawall work is on the Pine Island Sound side; the Gulf side is largely open beach. We evaluate each site on its own conditions.
How deep is Pine Island Sound near Captiva?
It varies. We check depth at mean low water before designing a dock or lift.
