J&M Marine Construction builds custom docks, boat lifts, and waterfront structures for homeowners along the Imperial River, Estero Bay, and the canals of Bonita Springs. With direct access to the Gulf and miles of tidal shoreline, Bonita Springs is built for boating — and a dock engineered for saltwater conditions makes all the difference. We handle design, fabrication, and installation in-house, building every structure to withstand Florida's sun, salt, tides, and storm seasons.
What We Build
Boat Lift Installation & Repair
Saltwater is hard on boats, and a custom lift is the best protection you can install on your Bonita Springs shoreline. We size cradle, cantilever, and elevator lifts to your vessel and the tidal range at your dock, keeping the hull out of the corrosive salt water to prevent staining, blistering, and marine growth. When an existing lift shows salt-related wear, our repair crew replaces motors, cables, and bunks to restore reliable operation.
Custom Welding & Fabrication
Every canal and bayfront lot in Bonita Springs is different, 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 tidal conditions and loads, not forced from generic parts that fail early in a salt environment.
Dock Construction & Decking
From a simple platform to an expansive waterfront entertaining space, we build docks around how you use the water. Choose composite, wood, or low-maintenance decking in finishes suited to coastal exposure. We engineer pilings and framing for tidal movement and storm loads, and we handle permitting and seawall considerations, so your Bonita Springs dock is safe, code-compliant, and built to last on saltwater.
Floating Dock Fabrication & Installation
With tidal swings along the Imperial River and bay, a floating dock keeps access consistent no matter the 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 paddle craft. Modular by design and built to resist salt, our floating docks can be configured to your shoreline and expanded over time.
Repairs, Maintenance & Accessories
Saltwater and storms take a toll on Bonita Springs waterfronts, and regular care keeps yours safe and sharp. We repair storm and corrosion damage, replace worn decking and hardware, service lifts, and add accessories like cleats, bumpers, ladders, and dock lighting. Whether you've inherited a weathered dock or want to upgrade, we'll restore your waterfront to top condition.
