Crack Sealing & Injection
$150 – $300 / ft. Hairline and surface cracks caught early, before they spread.
Fort Lauderdale cost guide
A straight answer for Broward County waterfront owners: what seawall repair really costs per linear foot, what drives the price, and how to know whether you need a repair or a full replacement.
The short answer
Most seawall repairs in Fort Lauderdale fall between about $150 and $1,200 per linear foot, depending on how serious the damage is. Small crack sealing sits at the low end. Major structural work — like helical piles, tiebacks, or a new cap — sits at the high end. A full replacement runs roughly $350 to $1,200 per linear foot, and a typical residential job lands somewhere between $40,000 and $120,000. Every wall is different, so the only way to get a real number is a proper on-site assessment — but this guide will get you in the ballpark before you make a single call.
Cost by repair type
Ranges are per linear foot of wall. Your actual price depends on the specifics below.
$150 – $300 / ft. Hairline and surface cracks caught early, before they spread.
$500 – $750 / ft. Replacing damaged concrete or vinyl panels in a limited area.
$600 – $900 / ft. Rebuilding the concrete cap that runs along the top of the wall.
$700 – $1,000 / ft. Adding anchors behind the wall to stop leaning and movement.
$800 – $1,200 / ft. Modern structural support to stabilize a failing wall.
$350 – $1,200 / ft. A new wall when repair is no longer enough — often $40k–$120k for a residential lot.
The big decision
Repair usually makes sense when the damage is localized, the wall is structurally sound overall, and you have caught the problem early — think isolated cracks, a small panel, or a section of failing cap. Replacement becomes the smarter money when you see bowing or leaning across long stretches, soil and foundation failure behind the wall, a wall that is simply past its lifespan, or repeated failures you keep patching. Repair is far cheaper up front, but pouring money into a wall that is structurally done wastes it. An honest assessment tells you exactly which side of that line your seawall is on.
Price drivers
Two walls of the same length can price very differently. Here is why.
Seawalls are priced per linear foot, so total length is the single biggest factor in your bill.
Sealing a crack and reinforcing a collapsing wall are worlds apart in labor and materials.
Concrete, vinyl, and rock or riprap each carry different costs and lifespans.
Tight lots or jobs that need water access by barge raise labor costs.
Soft or washed-out soil behind the wall adds stabilization work and cost.
Broward waterfront work often needs a permit, and taller or longer walls may need an engineer's report.
Local rules
Structural seawall work in Broward almost always requires a permit, and walls over a certain height or length may need a signed engineer's report plus compliance with local elevation standards. Permitting adds some cost and time, but it protects you — unpermitted seawall work can turn into a real problem when you go to sell the property. A good local contractor handles the permit process for you as part of the job. You can read more on our permit basics page.

Common questions
Repair is almost always cheaper up front — but on a failing wall, repeated repairs can cost more than one replacement over time.
Minor repairs can take a few days. Larger structural jobs or a full replacement can run several weeks, plus permit time.
