What drives the price
- Height. Raising a wall to meet a local minimum, such as Broward's 5 ft NAVD88 for substantial repairs, means taller panels, a bigger cap and more backfill.
- Wall type. Concrete panels, vinyl, steel and composite sheet piles cost different amounts to buy and install. See vinyl vs concrete.
- Soil and depth. Soft or rocky ground and deeper water need longer panels or different anchoring. Contractors note difficult soil alone can add $100–400 per foot.
- Access. Working from a barge on narrow canals costs more than working from the yard.
- Demolition and disposal of the old wall, and removing and reinstalling docks, lifts and pavers.
- Engineering, surveys and permits, plus state or federal approvals on some saltwater sites.
- Repair scope. In Broward, repairing more than half your shoreline can trigger the height rule. See the 5 ft rule.
Docks and boat lifts
Nationally, HomeAdvisor puts fixed docks on pilings at about $20–40 per sq ft and floating docks at $15–35. Florida coastal work with permits often runs higher. Boat lifts range from a few thousand dollars installed for small lifts to well over $15,000 for large ones with new pilings and power. Doing the seawall, dock and lift together can save on mobilization and permits.
Comparing quotes
Get two or three quotes, and make sure each states:
- the length of wall covered, in linear feet, and the type of wall
- the existing and finished cap elevation, in NAVD88
- panel length and embedment, and the tieback and anchor spacing
- what happens to the dock, lift, landscaping and pavers
- who pulls which permits, and whether engineering and surveys are included
- a payment schedule tied to inspections, not dates

Common questions
How much does it cost to replace a 100 ft seawall in Florida?
Using published 2026 ranges, roughly $50,000–150,000 at statewide guide prices of $500–1,500 per foot, and $150,000–350,000 for a South Florida wall built to current code at $1,500–3,500 per foot. Height requirements, soil, access and permits explain most of the difference.
Is seawall repair cheaper than replacement?
Usually much cheaper. Targeted repairs are published at about $35–600 per foot depending on the problem, compared with $500–3,500 per foot for replacement. But repeated repairs on a wall that's failing along its length can cost more over time. See repair or replace.
Does homeowners insurance pay for seawall repair?
Often not. Many policies exclude seawalls, docks and other structures at the water's edge, or cover them only for specific events. Check your policy and, after a storm, ask your insurer or agent before work starts.
