Complete replacement
Everything comes out — decking, framing and pilings — and a new structure goes in. This is the right approach when the existing pilings have lost embedment or integrity, because nothing built on top of them will outlast them.

Dock Replacement in Jacksonville & Northeast Florida
When repair stops making sense, rebuild it properly once.
In short
Dock replacement removes a structure that has reached the end of its service life and builds a new one in its place. It is the right call when the pilings or framing are failing broadly enough that repairs would be spent propping up a foundation that cannot carry them.
What replacement covers
- Complete dock replacement

In detail
How we approach this work
Partial reconstruction
Where the walkway pilings are sound but the terminal platform has failed, or vice versa, replacing one section and tying it into the other saves real money. It only works if the retained portion genuinely has years left, which we verify before proposing it.
Removal and disposal
Getting the old structure out is a substantial part of the job. Pilings generally need to be pulled rather than cut at the mud line, and all material has to be removed from the water and disposed of properly. It is usually a permit condition as well as good practice.
Redesign while you rebuild
A replacement is the one moment when changing the layout costs almost nothing extra. If the old dock was too short at low tide, had no terminal platform, or faced the wrong way for how you actually use the water, this is when to fix it.
Structural upgrades
Docks built decades ago were often framed for lighter use and lighter weather than they now see. Replacement is the chance to build in capacity for a lift, a roof, utilities or simply more people.
New materials
A rebuild lets you move to composite decking, better hardware and modern connection details without the cost penalty of retrofitting them to an old frame.
The point where repair stops paying
Owners rarely replace a dock because it failed all at once. They replace it because the repair bills stopped feeling like maintenance and started feeling like a subscription. That shift usually happens for a structural reason, and it is worth understanding which one applies to you.
A dock is really three systems. The pilings hold everything up and transfer load into the bottom. The frame spans between them. The deck is the wearing surface. Each has a different service life, and they do not fail in step.
Decking is consumable. You expect to replace boards. Framing lasts longer but can be repaired member by member. Pilings are the long pole — and when they go, everything built on them is living on borrowed time, regardless of how new the boards are.
The practical test is this: if you are replacing timber above sound pilings, you are maintaining a dock. If you are working on or below the pilings, you are usually paying a premium to delay a replacement.
Replacement is the cheapest time to change your mind
Nearly every dock we replace was built to suit an owner, a boat and a shoreline that have all since changed. The channel may have shifted. The low-tide depth at the end of the walkway may be a foot shallower than when it was built. The boat may be bigger. There may now be a reason to want a roof, a lift or a swim ladder that did not exist before.
Because the pilings are being driven anyway and the frame is being built anyway, the incremental cost of building the right dock rather than a copy of the old one is far smaller than people assume. Adding a terminal platform to a straight walkway, moving to a T configuration, extending twelve feet to reach workable water, or framing for a lift you will install in three years — all of these are modest adjustments during a rebuild and expensive projects afterwards.
Removal matters more than people expect
The part of a replacement that surprises owners is demolition. Taking a dock out of the water properly means pulling pilings rather than cutting them at the mud line, getting all of the material off the water rather than letting it drift, and disposing of treated timber appropriately. It needs the same equipment and water access as the build.
It is also usually a condition of the permit. A replacement authorisation that leaves old pilings standing in the waterway is not a completed project. We scope removal explicitly so it is visible in the price rather than discovered later.
If your structure is sound enough to save, dock repair is the better conversation. If you are starting over, the design thinking in dock construction applies in full.
How it runs
What working with us looks like
- 1
Condition assessment
We establish what, if anything, is worth keeping. Sometimes a set of pilings has real life left and the replacement is lighter than the owner expected.
- 2
Design the replacement
We size the new structure around current low-tide depth and how you want to use the water, rather than copying what was there.
- 3
Permitting
Replacement often triggers a different review path than repair, particularly if the footprint, length or configuration changes. We prepare the submittals and track them.
- 4
Removal
The old structure comes out and leaves the site. We protect the bank and surrounding vegetation during demolition.
- 5
Rebuild
New pilings driven, new frame, new deck, new hardware — with the layout you actually chose this time.
Before you decide
Questions worth answering first
Getting these right at the planning stage costs nothing. Getting them wrong is expensive to undo.
- Keep the footprint or change it?
- Rebuilding in the existing footprint is usually the simplest permitting path. Changing length, width or configuration may add review. The question is whether the better layout is worth the extra process — often it is.
- Is anything genuinely worth keeping?
- Retaining sound pilings can save a meaningful share of the cost. Retaining marginal pilings compromises an otherwise new structure. We are conservative about this.
- What has changed since it was built?
- Shorelines move, channels shift and low-tide depth at your dock may not be what it was twenty years ago. Rebuilding to the old length can mean rebuilding a dock that no longer reaches water.
- What are you adding later?
- If a boat lift, a roof or utilities are even a possibility in the next decade, framing for them now costs a fraction of adding them to a finished structure.
Answers
Dock Replacement — common questions
Is it cheaper to replace a dock or keep repairing it?
Over a short horizon, repair almost always costs less. Over a longer one it depends on how much of the structure is still sound. When pilings and framing are both failing, each repair is buying a year or two on a foundation that is itself running out, and the cumulative spend overtakes a replacement surprisingly quickly. We will give you the comparison for your specific structure rather than a general rule.
Do I need a new permit to replace an existing dock?
Usually yes, and the path can differ from a repair. Like-for-like replacement in the same footprint is generally the most straightforward case. Changing the size, length or configuration typically brings more review. Which agencies are involved depends on the waterway and the parcel. We prepare and track the submittals as part of the project.
What happens to the old dock?
It is removed and disposed of. In most cases pilings must be pulled rather than cut off at the mud line, and nothing may be left in the water. Removal and disposal are part of our scope and part of the quoted price.
Can I keep my existing pilings and just rebuild on top?
Sometimes, and when it is genuinely viable it saves a lot. But pilings are the hardest part of a dock to evaluate, because the critical section is underwater and the failure mode is internal. We will only recommend reusing pilings when we are confident they will outlast the new structure above them.
Can I change the shape of my dock when I replace it?
This is the best time to do it. Adding a terminal platform, moving from a straight dock to an L or T, or extending to reach deeper water costs far less as part of a rebuild than as a later modification. It may affect the permitting path, which we will explain before you decide.
How long is the water unusable during a replacement?
The structure itself is typically out of service for the duration of the on-site work, commonly two to four weeks for a residential dock depending on size and access. Permitting beforehand is the longer part of the calendar.
