Standard, custom, and composite built for Florida waterfronts.
A custom dock fits your lot, your boat, and how you actually use the water. Off-the-shelf kits force your dock into a generic shape with generic materials, while a custom build shapes around the real conditions on your shoreline. At J&M Marine Construction, we design and build custom docks for waterfront owners across Naples and Collier County
We are a licensed dock builder, in-house metal fabricator, and full pile-driving crew based at 2496 Kirkwood Ave in Naples. One team handles every step from first sketch through final board, with no rotating subcontractors and no hand-offs.
Stock kits cap out on size, finish, and saltwater performance. A custom build gives you decades more life, a dock that fits the spot, and a clean path through Naples permits and code.

01
Stock dock kits look easy on a website. They show up in a few boxes, the instructions look clear, and the price tag is lower than a full custom build. Then the dock hits Naples saltwater and the limits show up fast.
Where stock kits fall short:
* Sizes cap out at lengths and widths that do not fit most lots
* Layouts come in a handful of preset shapes
* Finishes weather faster than marine-grade alternatives
* Hardware grades are often below saltwater rating
* Float capacity is sized for freshwater zones, not Gulf chop
A custom build solves each of those. The dock shapes to your shoreline, water depth, and boat fleet — not the other way around. Marine-grade aluminum framing, stainless and hot-dip galvanized hardware, and saltwater-rated decking all carry through every part of the build.
Naples Gulf saltwater and storm cycles defeat most stock dock products inside a few years. The salt rusts cheap hardware, the chop breaks loose float connections, and the storms find any weak point. A custom dock built for Naples conditions runs decades instead of seasons.
Aqualane Shores and Royal Harbor lots rarely fit stock dimensions. The shoreline angles, water depths, and boat sizes in those neighborhoods almost always call for a build that bends to the lot.
02
Every custom dock comes down to a few major decisions. Locking those in early keeps the project moving and the budget tight.
The first decision is fixed vs. floating:
* Fixed docks sit on driven pilings at one set height
* Floating docks ride the tide up and down on floats
* Tide range, boat type, and shoreline access drive the choice
The second is material:
* Wood for classic look and warm feel
* Composite for low maintenance and even color
* Aluminum for the longest life and lowest care
* Hybrid builds mixing aluminum frames with composite or hardwood decks
The third is layout:
* Straight runs for narrow canal lots
* L-shapes with a head dock at the end
* T-shapes for boat tie-up on both sides
* U-shapes that wrap around a boat slip
* Finger piers and marina-style platforms for multi-boat sites
Add-ons round out the design:
Boat lifts and slip cutouts sized to your hull
Swim platforms and kayak launches
Fish cleaning stations with water and power
Lighting, dock boxes, and built-in seating
Permits and code review get folded into the design phase so the build moves without rework. We walk you through every decision during the design consultation.
03
Every custom dock project in Naples starts with a site visit. We walk your shoreline, measure the water, and talk through how you plan to use the dock. The visit happens before any drawing or quote.
What we measure on the site survey:
* Shoreline frontage along your lot
* Water depth at mean low tide
* Tidal range from high to low
* Bottom type — sand, muck, rock, or seagrass
* Setbacks from neighbor property lines
* Distance from the seawall and shore access
We also factor in what is already on the property. Existing pilings, seawalls, and shore access stairs all shape what the new dock can look like. So do the boats you own now and the boats you plan to own next.
Canal lots and open-bay lots in Naples follow different design rules. Canal lots have tighter setbacks and steady tidal swing, which often points to floating or fixed designs with specific anchoring. Open-bay lots get more wind, more chop, and different dock length limits.
You walk away from the site visit with a clear scope. We know what is possible, what is allowed, and what fits your goals — all before any drawing or permit work begins.

A custom dock is more than a walkway and a tie-up. The features we build into the design shape how your family actually uses the water — fishing, swimming, entertaining, or all three.
Features we build into custom Naples docks:
* Dock boxes for life jackets, lines, and gear
* Fish cleaning stations with running water and power
* Kayak and paddleboard launches at water level
* Boat lift slips and PWC racks built into the layout
* Swim ladders and step-down platforms
* Shade structures, bimini frames, and pergolas
Lighting and electrical features add another layer:
* Solar piling caps and low-voltage deck lights
* Underwater fishing lights for night fishing
* Shore power posts at each slip
* Marine-grade outlets and GFCI protection
Old Naples and Port Royal owners often combine three or four features into one custom build. A dock with a head platform for fishing, a swim ladder for kids, a lift slip for the main boat, and shore power for guests becomes a working part of the waterfront — not just a path to the water.
We plan every feature into the design from the first sketch so the framing, wiring, and plumbing all line up the first time.
Most Naples custom dock builds need permits before any pilings get driven. We run the full permit and engineering process so the paperwork stays off your desk.
The main approvals on a Naples custom dock:
* Collier County dock permit covering structure, setbacks, and zoning
* Florida DEP review for coastal and environmental impact
* Seagrass surveys when seagrass beds sit on your shoreline
* Mangrove protection compliance on mangrove shorelines
Each design package goes to permit-ready drawings before fabrication starts. The drawings include layout, framing details, piling locations, decking specs, and anchoring. Detailed plans move faster through county and state review than rough sketches.
What we do for you:
* Draw the dock and submit the full permit package
* Respond to reviewer questions and turn around revisions
* Coordinate seagrass and shoreline surveys when needed
* Meet inspectors on site during and after construction
You sign the application, and we run the rest of the process from submittal through final inspection. Permits and engineering work happen in parallel with material orders and fabrication, so the build stays on schedule when approvals come through.
A custom dock is one of the few home improvements that holds its value across decades on a Naples waterfront. The dock becomes part of the property record, the listing price, and the closing paperwork when the home eventually sells.
What a permitted custom dock gives you long-term:
* Documented value tied to the property record
* Engineered drawings on file for future repairs
* Permit paperwork ready for title companies and lenders
* Insurance coverage easier to maintain with proper records
* Faster closings when the waterfront paperwork is current
Title companies, lenders, and insurance carriers all look at dock paperwork during a Naples sale. A custom-built, permitted dock with engineered plans on file moves through closing without delay. Buyers and inspectors find what they expect, and the title company has the records it needs.
Stock kits and DIY docks often hurt value at closing. Buyers question the build quality, inspectors flag missing permits, and lenders pause when the paperwork is thin. Repair credits and price reductions follow.
Naples waterfront moves faster when the dock looks clean, holds up to inspection, and has the records to back it up. The custom build pays back at every stage — daily use, insurance, storm claims, and final sale.
A custom dock is built from scratch to fit your specific shoreline, boat, and lifestyle instead of using a stock kit. The design, materials, layout, and features all shape around your lot — not a generic plan. In Naples saltwater, custom builds outlast stock kits by decades because of marine-grade materials and proper engineering.
Three reasons custom is worth it on a Naples waterfront:
* Shoreline frontage, water depth, and boat sizes rarely fit a stock kit
* Custom builds use marine-grade materials rated for Gulf saltwater
* Permits, engineering, and resale value all require documented professional builds
The math favors custom every time on a property that sees daily salt, sun, and storm cycles.

A custom dock in Naples is a dock built from scratch to fit your specific shoreline, boat, and lifestyle. The design, materials, and layout all shape around your lot instead of pulling from a stock kit. The build uses marine-grade materials rated for Gulf saltwater.
Yes — Collier County and Florida DEP permits apply to most custom dock builds in Naples. We submit the full permit package, run revisions, and meet inspectors on site. Building without a permit can mean fines, forced removal, and resale problems down the road.
Marine construction in Florida requires a marine contractor license, not a standard general contractor license. DIY dock kits cap out on saltwater performance and rarely meet Naples code. Hiring a licensed dock builder protects your permit, your warranty, and your insurance coverage.
Yes — a well-built and permitted custom dock adds documented value to a Naples waterfront home. Title companies, lenders, and insurance carriers all look at dock paperwork during a sale. Permitted custom builds move through closing faster than stock or DIY docks.
Common features include boat lifts, swim platforms, fish cleaning stations, kayak launches, dock boxes, lighting, and built-in seating. We plan every feature into the design from the first sketch so the framing and wiring line up. Three or four features can combine into one connected dock.
Most full custom dock builds wrap in 4 to 12 weeks once we are on site. Permit time runs separately and often overlaps with fabrication. We start the paperwork the day you sign so the build stays on schedule when approvals come through.
