J&M Marine Construction designs and builds custom docks, boat lifts, and waterfront structures for homeowners in Longshore Lake. Built around a 88-acre lake, this established Naples community is made for waterfront living — and a private dock crafted for your lot lets you enjoy boating, fishing, and paddling right from home. We manage design, fabrication, and installation in-house, engineering every structure to stand up to Florida's sun, humidity, and storms while enhancing your Longshore Lake home.
What We Build
Boat Lift Installation & Repair
Keep your boat protected and launch-ready with a custom lift engineered for your Longshore Lake shoreline. We install cradle, cantilever, and elevator lifts matched to your vessel and lake depth, keeping the hull out of the water to guard against corrosion and marine growth. If your current lift is aging or noisy, our repair crew replaces motors, cables, bunks, and controls to restore reliable, quiet performance.
Custom Welding & Fabrication
Every Longshore Lake waterfront lot is different, so we fabricate custom pieces to fit yours exactly. Our in-house welding shop produces aluminum and steel components — frames, brackets, railings, ladders, and specialty hardware — engineered for continuous water exposure. This made-to-fit approach means stronger connections, cleaner lines, and a dock sized precisely for your dimensions and loads rather than forced from generic parts.
Dock Construction & Decking
Whether you want a simple platform or a spacious lakefront entertaining area, we build docks around your lifestyle. Choose composite, wood, or low-maintenance decking in finishes that complement your home. We engineer every piling and beam for durability and handle permitting and shoreline requirements, so your Longshore Lake dock is safe, compliant, and ready for years of enjoyment on the water.
Floating Dock Fabrication & Installation
For flexible, low-maintenance access, our floating docks are an excellent option. We fabricate and install marine-grade floating systems that move naturally with Longshore Lake's water levels, keeping access to boats, kayaks, and swim areas stable and safe. Modular by design, they can be configured to your shoreline and expanded down the road as your needs evolve.
Repairs, Maintenance & Accessories
Waterfront structures work hard in the Florida climate, and consistent upkeep keeps them safe and looking their best. We repair storm damage, replace worn decking and hardware, service lifts, and add accessories like cleats, bumpers, ladders, and dock lighting. Whether your Longshore Lake dock needs restoration or a few smart upgrades, we'll get it back in top shape.
