After a hurricane moves through Northeast Florida, most dock owners walk out to the water expecting to see the worst of it right away. Usually they don’t. The obvious damage is the decking that lifted and the railing that snapped. The expensive damage is almost always underneath, and it is the part people miss in the first week.
Here is what actually needs repair after a storm, roughly in the order it matters.
1. Loosened and Racked Pilings
Storm surge does not just push water up. It pushes it sideways, hard, and it drags debris with it. Pilings take that load first. A piling that has been racked out of plumb can still look fine from the top of the dock because the decking is holding it in position.
Signs to look for:
- Any piling that is visibly out of line with the others
- Gaps opening up where a piling meets a stringer or bracket
- Movement or a hollow knock when you push against a piling at chest height
- A ring of disturbed soil or scoured bottom around the base at low tide
This is the repair that gets more expensive the longer it waits. A racked piling keeps working itself looser every tide cycle, and it puts uneven load on the pilings next to it.
2. Decking and Fastener Failure
Lifted boards are the most common call we get after a storm, and they are also the most misdiagnosed. When a deck board pulls up in a hurricane, the board is rarely the problem. The fastener is, or the joist underneath it is.
Screwing a lifted board back down into a joist that has already been chewed up by the same forces buys a few months at most. The right fix is to check the framing under every board that moved, not just the boards you can see daylight through.
What to Check Before Re-Fastening
- Whether the joist still holds a fastener under load
- Whether the fasteners that failed were stainless or coated, since coated fasteners in salt water tend to give out as a group
- Whether the board pattern shows a twist, which usually means the frame moved and not just the deck
3. Cracked and Undermined Seawalls
Seawall and bulkhead damage is the quiet one. Surge pulls back out through the wall and takes fill with it. From the top you see a hairline crack or a small depression in the lawn. Below, you may have a void.
Two things to watch in the weeks after a storm: new low spots in the yard near the wall, and water that drains suspiciously fast after rain. Both point to fill loss behind the wall. If you are seeing either, our sea wall and bulkhead repair work is where that gets addressed before it turns into a wall replacement.
4. Boat Lift Motors, Cables and Alignment
Lifts take a beating in two ways during a storm. The obvious one is impact from debris or a boat that was left on the lift. The less obvious one is water intrusion into the motor housing and switch box, which can look fine on day one and fail three weeks later.
Before you run a lift after a storm, check that the cables still sit properly in the sheaves and that the cradle is level. Running a lift with a cable off its track is how a bad situation becomes a replacement.
5. Utility and Lighting Damage
Dock lighting, outlets and shore power take on water constantly during a surge event. Even sealed marine fixtures can trap salt water. This is a safety item, not a cosmetic one. Kill power at the breaker until every fixture and receptacle on the dock has been checked.
Document Everything Before Repairs Start
This is the step most homeowners skip and later regret. Before anything gets cut, pulled or re-fastened, take photographs. Wide shots that show the whole structure, then close shots of every failure point. Include something for scale. Note the date.
Insurance adjusters and county inspectors both work from documentation. Once a contractor has replaced a piling, the evidence of what that piling looked like is gone.
Common Questions After a Storm
How soon should a dock be inspected after a hurricane?
As soon as it is safe to walk on, and before you put weight on it or run a lift. Waiting for the water to settle is reasonable. Waiting a month is not, because minor movement becomes structural movement.
Can a dock be partially repaired, or does the whole thing have to be redone?
Partial repair is normal and it is usually what makes sense. Storm damage tends to concentrate on the exposed end and along the side that took the wind. What matters is whether the surviving structure is still sound enough to tie new work into.
Is it safe to use a dock that looks fine after a storm?
Looking fine and being sound are different things, particularly with pilings and seawalls where the damage sits below the waterline. If your dock took direct surge, treat it as unverified until someone has looked underneath.
Getting a Storm-Damaged Dock Back in Service
The pattern we see over and over is that homeowners fix what they can see, use the dock through the fall, and then call in spring when something structural finally gives. The repairs that were straightforward in September become a rebuild by March.
If your dock came through a storm and you are not sure what is going on below the waterline, our dock repair team handles assessment and repair across Duval, Clay, St. Johns, Nassau, Putnam, Flagler and Volusia counties. You can find your area on our service areas page and we will come look at it.
