Seawall repair in Brevard County runs $100 to $250 per linear foot for standard work, and climbs to $600 per linear foot when the damage is structural rather than cosmetic. A full replacement costs $150 to $600 per linear foot, which puts the average residential project between $15,000 and $60,000.
A typical residential wall on the Indian River Lagoon runs 75 to 100 feet. That puts most repair jobs in the $8,000 to $25,000 range, and most replacements well north of that.
Those are the numbers. The rest of this guide explains what moves them, because two walls of identical length on the same canal can quote 40% apart for reasons that have nothing to do with the contractor’s margin.
The 2026 price table
| Work | Cost per linear foot | 80 ft wall |
|---|---|---|
| Crack sealing and joint repair | $100 – $180 | $8,000 – $14,400 |
| Void filling (polyurethane injection) | $120 – $250 | $9,600 – $20,000 |
| Cap replacement only | $30 – $150 | $2,400 – $12,000 |
| Tieback / anchor repair | $200 – $400 | $16,000 – $32,000 |
| Toe berm / footer repair | $300 – $600 | $24,000 – $48,000 |
| Full replacement, vinyl sheet pile | $150 – $400 | $12,000 – $32,000 |
| Full replacement, reinforced concrete | $250 – $600 | $20,000 – $48,000 |
| Difficult access / barge required | up to $1,200 | $96,000+ |
These ranges are consistent across Florida cost surveys for 2026. Where Brevard differs from Sarasota or Fort Lauderdale is access: much of our lagoon frontage is reachable by land, which keeps the barge premium off most residential quotes.
The five variables that actually move your number
1. Whether the panels are sound
This is the single biggest fork in the road. If the wall itself is intact and simply leaking — soil escaping through joints, voids forming behind — the fix is injection and sealing, and you stay in the lower half of the table. If the panels have deteriorated, or the wall has started to lean, no amount of sealing buys meaningful time. You are looking at replacement pricing.
An honest inspection tells you which of the two you are in. A dishonest one sells you a repair twice.
2. Access
A crew that can back a truck to within 30 feet of the wall works at a completely different rate than one that needs a barge, a crane over a pool cage, or hand-carried material through a side yard. Access is often worth more than 30% of the total.
Before you call anyone, walk the property and note: how close can a vehicle get, is there a gate wide enough for equipment, is there anything permanent between the driveway and the water.
3. Wall height and water depth
A wall retaining 4 feet of soil is a different structure from one retaining 8 feet. Height drives panel length, embedment depth, and whether tiebacks are required at all. Water depth at the toe drives whether the crew works dry or wet.
4. What is behind the wall
A plain lawn is cheap to work behind. A pool deck, a paver patio, mature landscaping, or a screen enclosure raises the cost — sometimes substantially — because the work has to be staged around them, and because restoring what gets disturbed is part of the job.
This is why a $12,000 quote and a $19,000 quote on the same wall can both be honest. Ask each contractor what their number assumes about restoration.
5. Permits and survey
Every seawall repair in Brevard requires a permit. Properties on the Indian River Lagoon, the St. Johns River or Lake Washington also require a survey showing the surface water protection buffer line, plus stormwater retention of one inch of runoff.
Budget $1,500 to $4,000 for permitting and survey on a typical residential job, and expect it to be a separate line on the estimate. A quote that does not mention permits is either incomplete or the contractor plans to work without one — and unpermitted marine work becomes your problem when you sell the house.
Repair cost versus replacement cost: the real math
Homeowners often assume repair is always the economical choice. It usually is, but not always, and the crossover point is worth understanding.
A repair that addresses symptoms without addressing cause buys you three to five years. If your wall needs $14,000 of injection work today and will need replacement in four years anyway, you have spent $14,000 to defer a $30,000 job by four years — which is only rational if you are selling within that window.
The questions that decide it:
- Are the panels structurally sound, or just leaking? Leaking is repairable. Failing is not.
- Is the wall vertical? Any measurable lean means the tiebacks or the toe have moved. That is structural.
- How old is it? Concrete walls poured before roughly 1990 in this area were frequently built without the rebar cover or the tieback spacing that current practice requires.
- How long are you keeping the property? A wall with eight years left is a different decision for someone selling in two years than for someone staying twenty.
Why the cheapest quote is usually the most expensive
Three patterns show up repeatedly in seawall work on this coast:
The quote that excludes permitting. It looks cheaper by $2,000 to $4,000 because it is not the same scope.
The quote that treats the symptom. Sealing a visible crack without finding out where the soil is actually going. The lawn keeps sinking, and the second contractor charges you again to do it properly.
The quote with no linear footage on it. If a written estimate does not state the length being treated, the depth being worked to, and what happens to your landscaping, you cannot compare it to anything.
Insist on all three in writing. A contractor who will not put linear feet on paper is telling you something.
What a written estimate should contain
- Total linear feet being treated, and which sections
- The specific failure mode identified — joint leakage, cap spalling, tieback corrosion, toe scour
- Method and materials for each section
- Whether permitting and survey are included, and whose responsibility they are
- What is done to restore landscaping, decking or irrigation disturbed by the work
- Warranty terms, in years, and what voids them
- Payment schedule tied to milestones, not dates
What we do
Our inspection is free and produces the written document above. We measure the run, photograph the cap, joints, weep holes and waterline, and identify which of the failure modes is actually driving the problem — because that determines whether you are looking at a $9,000 repair or a $30,000 replacement.
If your wall has years left in it, that is what the report will say. We would rather inspect your wall three times over ten years than sell you a repair you did not need.
