Signs a seawall needs attention
Seawalls usually fail slowly, then all at once. These are the early signs a contractor will look for:
- Sinkholes or soft spots in the yard behind the wall, a sign that soil is washing out through joints or cracks.
- Cracks in the cap, or a gap opening between the cap and the panels below.
- Rust stains running down the face, from corroding steel in the cap or the tiebacks.
- A wall that leans or bows toward the water, which can mean failed tiebacks or anchors.
- Water coming through at high tide, especially during king tides. In Broward that matters legally as well as structurally (see below).
Our guide to repairing or replacing a seawall explains each one and the usual fix.
Repair or replacement in Broward
Many walls can be repaired: joints sealed or injected, a new cap poured, new tiebacks and anchors installed, or the toe protected with rock. Replacement is usually needed when most of the wall has moved or failed.
In Broward there's an extra question: how much of your shoreline the work covers. The county's tidal flood barrier rule treats work on more than 50% of the shoreline's length as a substantial repair, and a substantially repaired wall has to meet the minimum height of 5 ft NAVD88. That can turn a repair into a raise, which changes the price. Ask any contractor quoting you:
- What is the current cap elevation in NAVD88?
- Does this scope count as a substantial repair, and if so, is raising the wall included?
- If the wall is built to 4 ft now, is it designed to be raised to 5 ft later?
Our guide to the 5 ft rule covers the details, including the transition rules and how individual cities apply it.
What it costs in Broward
Seawall work is priced per linear foot. These are ranges published by Florida contractors and cost guides in 2026, not quotes:
| Work | Published range | Source |
|---|---|---|
| Targeted repairs, by failure | $100–600 per ft | South Florida marine contractor, 2026 |
| Concrete replacement | $1,500–2,200 per ft | Fort Lauderdale contractor |
| Vinyl replacement | $1,200–2,000 per ft | Fort Lauderdale contractor |
| Full replacement to current code, with permits | $1,500–3,500 per ft | South Florida marine contractor, 2026 |
On a 100 ft wall, that's roughly $10,000–60,000 for targeted repairs and $150,000–350,000 for a full replacement to code. Raising a wall to meet the height rule, difficult soil, and having to work from a barge instead of from land all push the price up. More detail is in the seawall cost guide.
Permits
Most seawall work in Broward needs a Broward County environmental licence for work in the water and a building permit from your city. Your contractor should apply for both in their own name, so the permits sit with the licensed professional doing the work. See seawall and dock permits in Broward.
If you've had a notice
The county code presumes a wall is in disrepair if tidal water flows through or over it. After a citation, the owner must show progress within 60 days and complete the repair within 365 days. Walls under 5 ft that let tidal water onto a neighbor's land or the street are treated as a public nuisance, on the same timeline. If you've had a notice, get an inspection and a written scope quickly. Permits alone can take weeks.

Common questions
Does a seawall repair in Broward have to raise my wall to 5 ft?
Only if it's a substantial repair, which the county defines as work on more than 50% of the length of your shoreline. New walls must also meet it. Walls permitted before January 1, 2035 can be built to 4 ft NAVD88 if they're designed to be raised to 5 ft by 2050. Smaller repairs don't trigger the height rule, but the wall still has to be kept in good repair.
How much does seawall repair cost in Fort Lauderdale and the rest of Broward?
Contractors in South Florida publish about $100–600 per linear foot for targeted repairs, and about $1,500–3,500 per foot for a full replacement built to current code. A Fort Lauderdale contractor puts concrete replacement at $1,500–2,200 per foot and vinyl at $1,200–2,000. Your written quotes are what count. See our seawall cost guide.
Do I need a permit to repair my seawall in Broward?
Usually two: a Broward County environmental licence for work in the water, and a building permit from your city (or the county in unincorporated areas). A licensed contractor should apply for both in their own name. See Broward seawall permits.
I've had a notice about tidal water coming through my seawall. What now?
Under the county code, a wall that lets tidal water flow through or over it is presumed to be in disrepair. After a citation, owners must show progress within 60 days and finish the repair within 365 days. Get a contractor to inspect it and give you a written scope as soon as you can, because permits take time.
