No Splinters, No Sealing
No annual sealing or staining, no rot in the boards, and color that is engineered into the material instead of painted on.
Composite docks: the honest comparison
Capped composite decking on pressure-treated framing and wrapped pilings — the low-maintenance dock, with its trade-offs stated plainly.
What Composite Buys You
Pay up front, or pay in maintenance forever
No splinters, no annual sealing or staining, no rot in the boards, and color engineered into the material instead of painted on.
Over a decade of South Florida sun and salt, that maintenance delta is most of the argument — composite costs more on day one and typically less to own. The trade-offs, plainly: composite runs hotter underfoot than wood in full summer sun, and board quality varies widely between products — uncapped or partially capped boards can swell and fade in constant-moisture marine use. We spec fully capped boards rated for marine environments and install them with hidden fasteners, and we'll tell you which products we won't put on a dock.
Why Composite
What you get, and the honest trade-offs
Low Lifetime Cost
Composite costs more on day one and typically less to own — over a decade of sun and salt, that maintenance delta is most of the argument.
Fully Capped Boards
We spec fully capped boards rated for marine environments and install them with hidden fasteners — and tell you which products we won't put on a dock.
Built on Real Structure
Pressure-treated framing sized for your loads, stainless hardware, and pilings driven to refusal and wrapped. A premium deck on a tired substructure is money wasted.
25+ Year Warranties
Quality capped boards carry manufacturer warranties of 25 years and up against rot, splintering, and fade.
Honest Trade-Offs
Composite runs hotter underfoot than wood in full summer sun. Lighter colors help — and we show you the options side by side.
The Structure Underneath
Composite is a decking material, not a structural one
Under the boards: pressure-treated framing sized for your loads, stainless hardware, and pilings driven to refusal and wrapped. A premium deck on a tired substructure is money wasted — if your framing or piles need work, the estimate says so before any boards go down. Weighing your options?

FAQ
Composite Dock Questions & Answers
Composite typically costs more installed. Wood then asks for sealing or staining on a recurring cycle plus board replacement as it weathers; composite mostly asks to be rinsed. Over roughly ten years the totals converge for many owners — the difference is whether you pay in money up front or maintenance forever.
It runs hotter than wood in direct summer sun — lighter colors help meaningfully. If a barefoot-friendly deck in full sun is your priority, we'll say so and show you the options side by side.
Quality capped boards carry manufacturer warranties of 25 years and up against rot, splintering, and fade. The framing and pilings underneath are what set the dock's real lifespan — which is why we build those right.
