Aluminum floating docks designed, built, and anchored for the long haul.
A floating dock rises and falls with the tide, so your deck stays at boarding height every hour of the day. That means safer steps on and off the boat, easier loading,and no climbing up to a high fixed deck at low tide. At J&M Marine Construction,we fabricate and install custom floating docks for waterfront owners across Naples and Collier County.
We are a licensed dock builder with our own in-house metal fabrication shop at 2496 Kirkwood Ave in Naples. Our crew cuts, welds, and assembles the dockframe right here, then brings it out to your shoreline for install. You get one team from drawing to splash, with no third-party handoffs.
This page covers how we design, fabricate, permit, install, and maintain floating docks built for Gulf Coast water. Call J&M Marine Construction today to book an on-site shoreline assessment.
Every floating dock starts with a visit to your Naples shoreline. We need to see the water, the bottom, and the access points before we draw a single line. A stock template will not work in Gulf Coast water.
Here is what we check on the site visit:
* Water depth at mean low tide
* Tidal range from high to low
* Bottom type — sand, muck, rock, or seagrass
* Wind and wave exposure from the open bay
* Shoreline access for delivery and install
* Setback distance from your property lines
Naples Bay and the canal systems off it have very different bottoms. Some lots sit on firm sand, others on soft muck that needs longer pilings or heavier anchors. Seagrass beds shape where we can place floats and how we anchor them under state rules.
The result is a dock design that fits your water, your boat, and your shoreline —not a copy of someone else's setup.
Floating docks are not one-size-fits-all. We fabricate each frame in our Naples shop to match how you plan to use the water. The shape, length, and width all flex around your goals.
Common layouts we build:
* Straight runs for canal-front lots
* U-shapes that wrap around a moored boat
* T-shapes with a main walkway and a head dock
* Finger piers for multiple boats or jet skis
* Wide platforms for swimming, fishing, and lounging
In neighborhoods like Aqualane Shores and Port Royal, families often want wider swim platforms with built-in storage benches and ladders. Other owners want kayak and paddle board launches on the low side. We size each section to fit your shoreline frontage and your dock plans.
Materials we use:
* Aluminum frame, welded in our shop
* Marine-grade flotation rated for the deck load
* Composite or hardwood decking, your choice
* Stainless cleats, ladders, and trim hardware
You end up with a dock that does what you actually need, built one time and built right.
A floating dock only works if it floats level and stays put. Three systems do that work: flotation, anchoring, and hardware. We size all three to your dock load, your water, and Naples storm season.
Flotation math starts with deck weight plus a safety margin. We add float capacity for people, gear, and boat side-loads. Under-floating leads to a soggy deck; over-floating wastes money and looks off.
Anchor choice depends on your bottom and tide range:
* Pile-guided floats for canal lots with tide swing
* Chain-and-block for deeper open water
* Stiff-arm anchors for shorelines with shallow access
Hardware is the part that fails first if you cut corners. Every bolt, cleat, and bracket we install is stainless or hot-dip galvanized for saltwater. Naples sits in the Gulf hurricane zone, so anchoring math matters every single year. We build for the storm, not just the calm day.
The payoff is a dock that holds level in chop, stays put through a blow, and looks tight years after install.

Most floating dock work in Naples needs permits before fabrication starts. We handle the paperwork so you stay out of the office and on the water.
Two main approvals apply to almost every job:
* Collier County dock permit for the local build
* Florida DEP review for coastal and environmental impact
The state also looks at seagrass coverage, shoreline buffers, and set back distance from property lines. We run the seagrass survey when one is required and adjust the dock layout to fit the rules. Drawings, site plans, and shoreline measurements all go in with the application.
What we do for you:
* Draw the dock and submit the full permit package
* Answer reviewer questions and submit revisions
* Coordinate the seagrass survey if needed
* Meet inspectors on site during and after install
Permit timelines in Naples shift with county and state workload. We start the paperwork early so the dock is ready to install when approvals come through. You sign the application, and we run the rest of the process to the finish.
Once the dock is fabricated and the permits are in, we move to your Naples shoreline for install. How we get the dock to the water depends on your lot.
Two delivery paths we use:
* Barge delivery for open-water sites and tight shorelines
* Truck and crane for canal lots with road access
Our shallow-draft barge handles the canal jobs in Old Naples and Royal Harbor,where bigger boats cannot reach. We bring the dock sections out, set them in place, and connect them on the water.
Install day work covers:
* Pile driving where pile-guided floats are spec'd
* Setting anchors, chains, or stiff-arms to the bottom
* Bolting deck sections together
* Mounting cleats, ladders, bumpers, and rub rails
* Running power and water lines if you want them
Most floating dock installs wrap in two to five working days on site, depending on size and layout. We test float level and anchor hold before the final walk-through.When you step on the deck and it stays put through a wake, the job is done.
Key Details
A floating dock in Naples water faces salt, sun, and storm cycles every single year. Without service, hardware loosens, floats wear, and decking fades. Annual maintenance keeps the dock tight and pushes the lifespan past 20 years on aluminum frames.
Our annual service visit covers:
Decking needs its own care cycle. Composite boards get a pressure wash and are-seal as needed. Hardwood decks need sand and seal on a tighter schedule to hold up to UV.
Wear parts we swap on a normal cycle:
Naples salt and UV speed up wear faster than freshwater dock zones. A dock on a service plan keeps its float level, its tight hardware, and its safe footing for two decades or more. A dock left alone often needs major work inside ten years.
Yes — most floating docks in Naples need permits before fabrication or install can start. Collier County issues the local building permit, and the Florida Department of Environmental Protection reviews coastal and environmental impact. Skipping either step can mean fines or a forced dock removal down the road.
Three approvals you should plan for:
* Collier County dock permit covering size, setbacks, and structure
* Florida DEP review for coastal impact and shoreline buffers
* Seagrass survey when your shoreline sits over a known seagrass bed
We handle all three on every Naples floating dock job, so the paperwork stays off your desk.
Whether you need a new floating dock, a replacement build, or a refit of your current setup, our crew is ready to help. We serve waterfront owners across Naples, Marco Island, and all of Collier County.

Yes — Collier County and Florida DEP permits apply to most floating dockprojects in Naples. We submit the full permit package, answer reviewer questions,and meet inspectors on site. You sign the application; we handle the rest.
With annual service, a floating dock on an aluminum frame and marine flotationcan last 20 years or more in Naples water. Salt, UV, and storm cycles wear thedock faster than freshwater zones. Routine maintenance is what keeps it inservice that long.
Yes, floating docks work well in both canals and open water around Naples. Pile-guided floats handle canal tide swings and keep the dock from drifting. We pickthe anchor style based on your bottom type and tidal range.
Size depends on your shoreline frontage, setbacks, and Collier County rules. Wemeasure during the site visit and design within the limits the county and stateallow. Larger docks often need extra permit review and seagrass survey work.
A floating dock rises and falls with the tide, keeping the deck at boarding heightall day. A fixed dock sits on pilings at one set level, so the step down to your boatchanges with the tide. Floating docks make boarding safer in areas with a bigtidal swing.
Yes, we repair and refit any brand of floating dock. Common refits include newfloats, swapped decking, fresh hardware, and new cleats or ladders. You do nothave to rebuild the whole dock to fix the parts that wear out.
