7 Florida-licensed marine & seawall subcontractors serve Naples (Collier County). Browse listings below, or create a free* GC account to see phone and email and invite a sub to bid on your RFQ.
Most of these marine & seawall subcontractors are based in Naples (2) and Marco Island (1) — plus 4 more across the metro.
Marine and seawall subcontractors build the waterfront structures that let a property meet the water — seawalls and bulkheads, fixed and floating docks, pile driving, boat-lift foundations, riprap revetments, and the coordination work tied to dredging. On commercial and coastal residential jobs they price from the marine drawings and geotechnical report, sequence around tides and weather, and bring specialized equipment — barges, marine cranes, pile hammers — to install work that lives under water as much as above it.

A marine RFQ usually points at the marine drawings, the geotech, and any environmental permit conditions, with a clear scope: structure type, pile and panel material, linear footage, dredge or backfill volume, and any tieback or deadman detail. For bid prep a GC typically wants the quote broken out by structure so bids compare cleanly, confirmation the sub priced to the drawings, and an honest read on the environmental permitting timeline — DEP, USACE, and local agencies — since that often drives the project schedule. Site visits are typical because tide, access, and existing conditions all move the number.
Marine contracting is a state-licensed trade in Florida, regulated by the Construction Industry Licensing Board (CILB) under the DBPR as a specialty contractor classification covering seawalls, bulkheads, docks, and related waterfront work. Like other CILB trades the license comes in two tiers — certified, which authorizes statewide work, and registered, which is limited to the local jurisdiction that issued the competency card. Environmental permitting — the Florida Department of Environmental Protection, the U.S. Army Corps of Engineers, and applicable local agencies — runs in parallel to the CILB license and is a separate due-diligence step in any marine RFQ.
Yes. Marine contracting is a CILB specialty contractor classification under the DBPR, covering seawalls, bulkheads, docks, and related waterfront work. Certified licenses authorize statewide work; registered licenses are limited to the local jurisdiction.
No. The CILB license authorizes the construction work itself, but environmental permits — DEP, U.S. Army Corps of Engineers, and local agencies — are administered separately. GCs typically scope the permitting timeline into the RFQ.
The marine drawings, the geotechnical report, any environmental permit conditions, structure type, pile and panel material, linear footage, dredge or backfill volume, the bid deadline, and whether a site visit is required — typically yes for marine work.
Yes. GCs post an RFQ and invite matched subs by trade and service area; invited subs are notified and can submit a bid for your bid prep.
Listings are seeded from public Florida DBPR license data, and a sub can claim its listing and upload a credential for a one-time review. The badge reflects what was reviewed: a verified state license earns License Verified — the usual path for a marine sub — a verified certificate of insurance earns Insurance Verified, and a sub with both reviewed shows the Verified Pro umbrella.
