Good questions bring it to the surface.
If your dock is starting to feel spongy underfoot, wobble when you walk out to the end, or show rusted hardware and cracked pilings at the waterline, it is telling you something. On the Intracoastal, the Matanzas, and the tidal creeks around St. Augustine, docks take a beating that inland structures never see, and small problems turn into expensive ones faster than most owners expect.
Start by separating surface wear from structural movement. Soft decking may be limited to boards; movement, leaning pilings, stretched hardware or soil loss can point to a deeper issue. The guides below help you describe what changed and ask more useful questions before work is scoped.

A first walk-through
Four places to look before you make the call
This is not an inspection or a safety determination. It is a practical way to notice and describe what has changed.
- 01
Deck surface
Soft spots, flexing boards, raised fasteners and places that stay wet after the rest dries.
- 02
Frame & hardware
Loose through-bolts, rust trails, stretched connections and movement where the walkway meets the platform.
- 03
Pilings
Leaning supports, splitting at the splash zone and hidden damage below the waterline.
- 04
Load & shoreline
Boat-lift mounts, roofs, changing boat weight, scour and soil loss behind a seawall.
Along the water

Straight answers
Questions waterfront owners ask first
General information for planning—not a diagnosis, engineering opinion or quote for a particular structure.
How much does dock repair cost in St. Augustine?
It depends entirely on scope. A few deck boards and fresh hardware is a small job; pilings, framing or storm damage runs higher, and a full rebuild is a different order of cost. That is exactly why catching problems early pays off. Insist on an itemised quote after an on-site look, so you have a real number before any work begins rather than a range over the phone.
Do I need a permit to repair or build a dock in St. Johns County?
Some qualifying single-family dock repairs or replacements may use a Florida DEP exemption or self-certification, while other work can require county, state, submerged-land or federal authorization. Eligibility depends on the property and scope. Confirm the path with the agencies before work begins and settle who files, what it costs and what happens if approval is denied.
Which St. Johns County areas have local waterfront guides?
The local guides include St. Augustine Beach, Vilano Beach, Crescent Beach, Butler Beach, Marineland and Switzerland, with the broader geographic guide covering Ponte Vedra Beach, Nocatee, Palm Valley and surrounding waterways.
Why do docks and seawalls fail so much faster here?
Brackish tidal water and marine borers. The constant wet-dry cycle at the waterline rots wood and corrodes steel faster than anywhere else on the structure, and shipworms hollow out untreated pilings from the inside while they still look solid. It is why a dock that seemed fine can suddenly feel unsafe, and why an early look is worth it.
Does submitting a request guarantee a quote?
No. Submitting the form does not produce or guarantee a quote, contractor introduction or response. If an introduction is offered, ask the independent contractor directly about inspection fees and quote terms before scheduling.
When you are ready
Tell us what is happening at the waterline.
Describe what changed, where you see it and how the structure behaves at different tides. Those details make the first review more useful.
- Note movement, softness, corrosion, damaged pilings or soil loss.
- A phone number is optional.
- Submitting does not guarantee a contractor response or quote.
