Dock Repair: what it involves
Most private docks around Kings Bay and along the Crystal River are wood: treated pilings driven into the bottom, beams and stringers bolted across them, and deck boards on top. A few are floating docks on canals where the water rises and falls with the tide. Each layer ages at its own pace. Deck boards crack and splinter in the sun, stringers rot where water sits on them, and galvanized bolts and brackets rust long before the wood gives out.
A good repair starts below the deck. The contractor checks each piling at the waterline and the mudline, looks at how the beams are bolted on, and pulls a few boards to see the stringers. If the frame and pilings are sound, new boards and hardware give the dock years more life. If the frame is soft or the pilings are failing, a rebuild on the same footprint is often the better buy, and it may stay within the dock's existing permit.
Signs your dock needs work
- Boards that flex, crack or have popped screws and nails
- A dip or sag between pilings
- Rust streaks around bolts and brackets
- The dock sways or shifts when someone walks on it
- Gaps between the walkway and the seawall or the shore
Take a few photos from the water side if you can; it helps the contractor price the job.
Free EstimateCommon methods
Board and hardware replacement
Damaged deck boards are swapped for new treated wood or composite, and rusted bolts, brackets and screws are replaced with hot-dip galvanized or stainless hardware.
Stringer and beam repair
Rotted stringers are sistered or replaced, and beams are re-bolted to the pilings so the deck sits flat and stops moving.
Rebuild on the same footprint
When the frame is past saving, the old dock comes out and a new one goes in on the same layout, which keeps the permit work simpler.
Does dock repair need a permit?
Some small repairs don't, but many do. Inside city limits, the City of Crystal River's dock checklist covers dock work, charges 1.5 percent of the contract value with a $100 minimum, and requires five-foot setbacks from each side property line. New pilings also need a Florida DEP and U.S. Army Corps of Engineers permit or a letter of exemption. Outside the city, Citrus County issues the building permit. Ask the contractor to pull it in their name.

How a dock repair job usually goes
- Look from the waterThe contractor checks pilings, beams and hardware from a boat or kayak, not just from the deck.
- Test the frameA few boards come up so the stringers and beam bolts can be checked.
- Price repair and rebuildYou get a written price for the repair, and for a rebuild if the frame is borderline.
- PermitsThe contractor files with the city or county, and with DEP if pilings are involved.
- Build and walk itAfter the work, you walk the dock together and check that nothing moves.
Ask whether the new hardware is hot-dip galvanized or stainless; plain zinc-plated parts don't last on salt water.
What dock repair costs
HomeAdvisor puts typical boat dock repairs at about $823 to $5,294, with a national average near $3,050. Replacement boards run about $4 to $35 per square foot depending on material. A full rebuild of a larger dock with new pilings can cost many times that, so ask for both prices when the frame is borderline.

A loose board today is cheaper than a failed stringer next summer.

Dock Repair questions
Can you fix just part of my dock?
Yes. Many jobs are a section of boards, one stringer or a few brackets. The contractor will tell you if the rest needs attention.
Composite or wood boards?
Composite costs more up front but doesn't splinter and needs less upkeep. Treated wood is cheaper and easy to repair. Both work over a sound frame.
Do floating docks need different repairs?
Yes. Floats, connectors and the hinge to the shore take most of the wear, and they're priced as parts.
