J&M Marine Construction designs and builds custom docks, boat lifts, and waterfront structures for homeowners across Marco Island. With miles of Gulf-access canals, bay frontage, and beachside waterways, this premier island destination is built for boating — and its docks must be engineered for saltwater, tides, and storm exposure. We handle design, fabrication, and installation in-house, building every structure to withstand Florida's sun, salt, and seasonal storms.
What We Build
Boat Lift Installation & Repair
On a Gulf-access island like Marco, protecting your boat from salt water is essential. We install cradle, cantilever, and elevator lifts sized to your vessel and canal depth, keeping the hull elevated to prevent corrosion, staining, and marine growth. When an older lift begins to fail in the salt air, our repair team replaces motors, cables, bunks, and switches to restore smooth, reliable operation.
Custom Welding & Fabrication
Every canal and bayfront lot on Marco Island is unique, so we fabricate to fit yours exactly. Our in-house shop welds marine-grade aluminum and stainless components — frames, brackets, railings, ladders, and specialty hardware — engineered to resist saltwater corrosion. Building to fit means stronger connections and cleaner welds sized precisely for your loads and tidal conditions, not forced from off-the-shelf parts.
Dock Construction & Decking
From an efficient boating platform to a luxurious waterfront retreat, we build docks tailored to how you live on the water. Choose composite, wood, or low-maintenance decking in finishes that complement your island home. We engineer pilings and framing for tidal movement and storm loads and integrate with your seawall, handling permitting throughout, so your Marco Island dock is safe, compliant, and built to last.
Floating Dock Fabrication & Installation
With tides moving through Marco's canals and bays, a floating dock keeps access reliable at any water level. We fabricate and install marine-grade floating systems that rise and fall with the tide, giving you stable boarding for boats, kayaks, and paddleboards. Modular and corrosion-resistant, they can be configured to your shoreline and expanded as your needs grow.
Repairs, Maintenance & Accessories
Marco Island's saltwater and storm exposure are hard on docks and lifts, so routine care keeps yours safe and attractive. We repair storm and corrosion damage, replace worn decking and hardware, service boat lifts, and install accessories like cleats, bumpers, ladders, and lighting. Whether your dock needs a full restoration or a few upgrades, we'll bring it back to peak condition.
