Seawall cost per foot in Palm Beach County: every published range compared
Updated November 6, 2026
Seven published price ranges, side by side, with the source and date for each, plus a calculator.
Published seawall prices for South Florida run from $175 per linear foot (vinyl sheet pile on a protected canal) to $2,000 per linear foot (deep water, heavy engineering). Most of that spread is not disagreement. It comes from what each source includes, the wall material, how exposed the water is, and how old the number is. Below, every range we could find is shown side by side with its source and the date we read it, followed by a calculator that multiplies your wall length by each range.
West Palm Seawalls is not a contractor and does not quote, bid or perform seawall work. These are other parties' published figures, not quotes. A licensed marine contractor and, for structural work, an engineer set the real number for your wall.
Every published range, compared
| Source (type) | Area it describes | Published range | What the range covers |
|---|---|---|---|
| JKT Marine (marine contractor) | Palm Beach and Broward | $175 to $275 per ft (vinyl); $250 to $400 per ft (concrete panel) | New wall, installed, cap included. Separately: engineering $2,000 to $5,000 and permits $800 to $3,000 per project. Full replacement all-in $25,000 to $80,000+. |
| Sea Me Dive (marine contractor) | South Florida | $175 to $400 per ft | "Published estimates for some new seawall systems." Worked example: 100 ft at $250 per ft is about $25,000 before other project costs. |
| Team Renick blog (Sarasota real estate blog, published Sept. 24, 2026) | South Florida row | $175 to $350 per ft (vinyl); $250 to $400 per ft (concrete) | Typical 75 to 100 ft total $25,000 to $80,000. The same table shows Sarasota/Manatee at $500 to $900 (vinyl) and $650 to $1,200 (concrete). Permit fees can add $1,000 to $3,000 or more. |
| South Florida Seawall (marine contractor) | Broward and Palm Beach | $500 to $1,200 per ft | New seawall construction, installed, "depending on material (vinyl vs. concrete), wall height, soil conditions, access for equipment, tie-back requirements, and permitting complexity." |
| LandPerc (Florida engineering firm) | Florida | $150 to $600 per ft (most residential); $700 to $2,000 per ft (high-erosion) | Construction cost. Also gives $100 to $800 per ft as a statewide spread and $10,000 to $100,000 per project. |
| TRULINE (seawall system manufacturer) | Fort Lauderdale (2016 survey), South Florida | $650 to $2,000 per ft; $1,000 to $2,000 per ft | Quotes a City of Fort Lauderdale FAQ: contractors surveyed in May and June 2016 quoted $650 to $2,000 per ft depending on waterway depth and location, plus $2,000 to $5,000 for engineering and permitting. Adds $1,000 to $2,000 per ft for substantial saltwater walls (2023 estimates). |
| Pearce Marine (Long Island, NY contractor) | National, not Florida | $150 to $800 per ft; $700 to $2,000 per ft (high-erosion or commercial) | Shown for contrast only. This page ranks for Florida searches but its numbers describe New York and national work. |
All figures fetched November 6, 2026 from the linked pages. Sources are contractors, a manufacturer, an engineering firm and a real estate blog; none is a government cost survey except the 2016 Fort Lauderdale figures that TRULINE quotes.
Why the ranges disagree
- Material. JKT Marine prices vinyl sheet pile at $175 to $275 per ft and concrete panel at $250 to $400 per ft, and recommends vinyl for protected canals and concrete for Intracoastal and open water.
- Water exposure and depth. The $650 to $2,000 figures come from deeper or more exposed water (the Fort Lauderdale survey varied "depending on the depth of the waterway") and from high-erosion sites (LandPerc, Pearce).
- What is included. Some ranges are wall-only; JKT lists engineering ($2,000 to $5,000) and permits ($800 to $3,000) as additions. SFL's $500 to $1,200 is an installed price that it says varies with tie-back requirements and permitting complexity.
- Region and age. Team Renick's own table runs about two to three times higher in Sarasota/Manatee than its South Florida row. The Fort Lauderdale survey is from 2016.
Repair prices (when the wall is still standing)
| Repair | JKT Marine published range |
|---|---|
| Cap crack seal and waterproof coating | $20 to $45 per ft |
| Partial cap repair or section replacement | $60 to $120 per ft |
| Full cap removal and replacement | $100 to $200 per ft |
| New cap with weep holes | $120 to $220 per ft |
| Hairline crack sealing | $800 to $2,500 per job |
| Crack injection (epoxy or polyurethane) | $2,000 to $8,000 per job |
| Tieback anchor installation | $10,000 to $30,000 per job |
| Riprap or revetment | $5,000 to $20,000 per job |

Seawall cost calculator
Enter your wall length and the kind of work. The calculator multiplies length by each published per-foot range and, if you tick the box, adds JKT Marine's published engineering ($2,000 to $5,000) and permit ($800 to $3,000) ranges. Formula: low = feet x low rate + adders low; high = feet x high rate + adders high.
How to use these numbers
Use the vinyl and concrete rows as a floor for a protected canal and the $500 to $2,000 rows as the ceiling for exposed or deep water. Ask each contractor to price the same scope in writing: length, material, cap, tie-backs, demolition and disposal, engineering, and permit fees. Permits, state exemptions and Army Corps rules are covered in the seawall permit guide, and city height minimums in seawall height by city.

Questions, answered
FAQ
How much does a seawall cost per foot in Florida?
Published South Florida ranges start at $175 to $275 per linear foot for vinyl and $250 to $400 for concrete panel (JKT Marine), and reach $500 to $1,200 (South Florida Seawall) and $650 to $2,000 for deep or exposed water (2016 Fort Lauderdale survey quoted by TRULINE). Sources fetched November 6, 2026.
How much does it cost to replace a 100 foot seawall in Palm Beach County?
At the published per-foot ranges, 100 feet is about $17,500 to $27,500 for vinyl and $25,000 to $40,000 for concrete panel (JKT Marine), before engineering ($2,000 to $5,000) and permits ($800 to $3,000). South Florida Seawall's range would put the same wall at $50,000 to $120,000.
Why do seawall cost estimates vary so much?
Material, water depth and exposure, what the price includes (wall only or all-in with tie-backs, demolition, engineering and permits), region and the age of the figure all move the number.
Is seawall repair cheaper than replacement?
Usually. JKT Marine publishes cap repairs from $20 to $220 per foot depending on condition and says repair typically costs 15 to 40 percent of full replacement.
