Standard, custom, and composite built for Florida waterfronts.
Composite decking gives Naples boat and dock owners a tougher, lower-maintenance surface that stands up to salt, sun, and daily wear. No more splinters underfoot, no more yearly sanding and sealing, and no more peeling non-skid on the boat deck. At J&M Marine Construction, we upgrade decks on docks and boats with marine-grade composite and SeaDek-style materials.
We are a licensed dock builder and metal fabricator based at 2496 Kirkwood Ave in Naples. One crew handles the dock board swaps, the boat surface upgrades, and the finish work. You get marine-grade materials and a clean install from a team that builds and repairs docks every day.
Whether you want to replace tired wood boards on a long dock or add a soft, cool surface to the deck of your boat, the upgrade pays off in look, comfort, and care time. Call J&M Marine Construction today to book an upgrade consultation.
For dock builds, we most often recommend Trex composite decking, an industry-leading marine-grade material engineered to resist salt, UV, and moisture — ideal for Naples waterfront conditions.
01
If your Naples dock has rotted boards, splinters, or sun-faded planks, a composite swap brings the surface back to like-new. We pull the old wood and replace it with marine-rated Trex, TimberTech, or similar composite. The new deck holds its color, resists rot, and stops feeding splinters into your feet.
What we install:
* Marine-rated composite boards in classic and tropical colors
* New stainless screws or hidden fasteners on every board
* Replacement trim and edge banding where needed
Naples salt, UV, and humidity wear out wood faster than freshwater dock zones do. A board that lasts 20 years in a lake might give you 8 to 10 years here. Composite shrugs off all three.
Old Naples and Aqualane Shores owners often switch to composite during a full dock refit. The dock goes from a yearly sand-and-seal chore to a quick rinse-and-go surface. You spend less time on dock care and more time on the water.
02
Your boat deck takes more abuse than almost any surface on the water. Sun, fish blood, sunscreen, and wet feet wear down carpet, raw fiberglass, or peeling factory non-skid. We install boat-surface decking that solves all four problems at once.
Products we install:
* SeaDek closed-cell foam decking
* MarineMat and similar EVA foam products
* Custom-cut pads for the helm, cockpit, and cooler tops
Each piece is cut, beveled, and bonded to your boat's deck for a finished factory look. The foam adds cushion underfoot and stays cooler than raw fiberglass in Gulf sun. That matters on a Naples boat day when the helm sits in the heat for hours.
Grip when wet is the other big win. Foam decking holds your feet on a slick deck better than most factory non-skid. For offshore and bay fishing out of Naples Bay, that grip turns into a safer, more stable platform every trip.
03
Picking the right material depends on where it goes and how you use it. Dock surfaces and boat surfaces call for different products, and each one has its own color, texture, and care path. We bring samples to every consultation in Naples so you see and feel each option before any work starts.
Dock composite options:
* Trex marine-rated boards
* TimberTech composite lines
* Other marine-grade brands in classic and tropical colors
Boat-surface options:
* SeaDek foam decking in custom colors
* EVA foam pads cut to factory or custom layouts
* Logos, names, and patterns laser-cut into the surface
Each product solves a different problem. Composite handles sun, rain, and salt better than wood and never needs sealing. SeaDek and EVA foam shrug off fish blood, sunscreen, and bare feet without staining or peeling.
You leave the consultation with samples in hand, color choices made, and a clear scope for the upgrade. No guesswork once the install crew shows up.
04
The surface only holds up if what is under it is right. We check framing on the dock and prep the deck on the boat before any new material goes down. Skip that step and the upgrade fails inside two seasons.
On dock composite jobs, we look at:
* Stringer spacing — composite needs tighter spans than wood
* Fastener pattern matched to the brand specs
* Ventilation under the deck for drainage and airflow
* Rotted framing that needs replacement first
On boat-surface jobs, we run a full prep sequence:
* Deep clean of the existing deck surface
* Sand or scuff to give the adhesive bite
* Solvent wipe to pull off oil, wax, and sunscreen
* Full dry before any foam pad touches the surface
Wrong prep is the top reason composite and SeaDek jobs fail early in Naples. The humidity here adds extra steps — surfaces must be fully dry before bonding, or the adhesive lifts within months. We work in shaded hours and watch the dew point on every install.
The result is an upgrade that bonds tight and stays tight for the full life of the product.
Once prep is done, our crew runs the install. The same team handles dock boards, boat-surface foam, and all the finish work in between. One crew, one schedule, one clean handoff.
Dock composite install sequence:
* Pull and dispose of the old wood boardsInspect and repair framing as needed
* Lay out new composite with proper gap spacing
* Drive stainless screws or set hidden fasteners
* Cut and fit trim, edge banding, and corners
Boat-surface install sequence:
* Pattern the deck areas to be covered
* Cut the foam to shape with beveled edges
* Test fit and mark adhesive zones
* Bond pads to the prepped surface
* Roll out air pockets and trim final edges
Custom finish work brings the upgrade home. We add laser-cut logos, boat names, hatch pads, helm pads, cooler tops, and fish boxes on boat jobs. On Naples docks, we finish out trim caps, post wraps, and stair treads to match the new deck.
Most dock decking refits wrap in two to five days on site. Boat-surface jobs run one to three days based on the deck size and the number of custom pieces.
Composite and foam decking both need far less care than wood or carpet. A simple cleaning routine keeps the surface looking new and the warranty intact for years.
Dock composite care:
* Rinse with fresh water after heavy rain or salt spray
* Scrub with mild soap and a soft brush a few times a year
* Keep pressure washer nozzles back at least 12 inches
* Skip harsh solvents and oil-based cleaners
Boat-surface foam care:
* Rinse the deck after every trip, especially after fishing
* Scrub with a soft brush and mild boat soap as needed
* Avoid solvents, acetone, and harsh chemical cleaners
* Cover the deck or dock the boat in shade when possible
Both surfaces resist mold, mildew, and UV damage when cleaned on schedule. Naples salt and sun call for quarterly deep cleans on both products to keep colors bright and surfaces grippy.
Port Royal and Royal Harbor owners often add a yearly inspection to their service plan. We come out, check fasteners and adhesive bonds, deep clean the surface, and flag any spots that need attention. A small yearly visit pushes the lifespan of the upgrade past its warranty term.
Yes — marine-rated composite decking works well on Naples docks when installed with proper framing and fasteners. Brands like Trex and TimberTech are rated for saltwater use above the splash zone, which covers most fixed dock surfaces in Naples. Composite resists rot, splinters, and UV fade far better than untreated wood.
Three conditions matter for a successful install:
* Stringer spacing matched to the composite brand's specs
* Stainless or hidden fasteners rated for saltwater
* Above-water install only — composite is not rated for full submersion
We check all three before any new boards go down, so the upgrade holds up for the full life of the product.
Whether you want a low-care composite dock surface or a soft, cool foam deck on your boat, 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 dock builds in Naples. We submit the full permit package, run revisions, and meet inspectors onsite. You sign the application; we handle the rest of the process.
Dock length depends on water depth, setbacks, and state shoreline limits. We measure your water and review the rules during the site visit before we set a final length. Open-water lots in Naples often allow longer docks than canal-front lots.
Standard residential dock boards are 5/4 inch thick in Naples builds. Thicker boards work better for long spans, heavy traffic, or open-water docks that take wave action. We pick board thickness based on stringer spacing and how you plan to use the dock.
Yes — marine-rated composite boards like Trex and Timber Tech work well on Naples docks with proper framing. The framing under the deck needs to match the composite's span and fastener rules. We build the frame to spec so the deck holds up for the long run.
Most full Naples dock builds wrap in two to four weeks once we are on site. Permit time runs separately and can add weeks before construction starts. We start the paperwork early so build time and permit time overlap.
Yes — we match decking, layout, trim, and hardware to keep the look consistent across the property. This is common when owners add a section, replace a deck, or rebuild after storm damage. Bring photos or invite us out to the site to see the original.
