Dock decking replacement
If the frame and floats are sound, new decking can make an old dock feel new. Here's how owners weigh the options.
Decking takes the hardest wear on a dock. It bakes in the Oklahoma summer sun, stays wet after storms and gets walked on by wet feet, coolers and fishing gear. Boards split, fasteners back out and surfaces turn slick or splintery. Replacing just the decking is often the most affordable way to extend a dock's life, as long as what's underneath is still in good shape.
What decking materials are used?
| Material | Strengths | Trade-offs |
|---|---|---|
| Treated wood | Lowest upfront cost, familiar look, easy to repair | Needs sealing; boards can split, warp or splinter |
| Composite or PVC | No splinters, little upkeep, many colors | Heavier; some colors run hot in full sun |
| Aluminum | Light, strong, drains quickly | Can feel hot; a different look and sound underfoot |
| Grated or light-pass panels | Let light and water through | Different feel; not ideal for every area |
Check the frame and floats first
New boards on a rusted frame or failing flotation won't last. A good contractor will look at welds, joists, fasteners and floats before quoting a deck. If the dock is riding low, see dock repair and flotation first, since GRDA requires marine-grade, fully encased flotation.
Heat and footing
If you'll be barefoot on the dock, ask for samples you can leave in the sun, and ask about textured surfaces for slip resistance. Weight matters too: a heavier deck changes how the dock sits, so the contractor should confirm the flotation can carry it.
Signs it's time to redeck
- Soft spots or boards that flex underfoot
- Splits, splinters or raised screw heads
- Gaps opening between boards
- A surface that stays slick after rain
Will new decking need GRDA's permission?
Resurfacing within the dock's existing footprint is a different job than enlarging it. GRDA's rules require permission for any modification, change, addition or improvement to a dock, so if the decking job comes with a bigger platform, new slips or other changes, check with GRDA first.
We don't put prices on this site. The dock contractor you're connected with prices the job after seeing your shoreline, water depth and access, and anything said over the phone is only a rough starting point.

Common questions
Is composite worth it over wood?
It costs more up front but avoids sealing and splinters. Wood is cheaper to install and repair. The right answer depends on budget, sun exposure and how long you plan to keep the dock.
Can you redeck without replacing the frame?
Yes, if the frame and flotation are sound. The contractor should inspect both before quoting.
