What makes an Upper Keys quote change?
- Investigation: surveys, underwater condition work and any required benthic assessment.
- Access: equipment size, barge arrangements, staging and restoration of a narrow lot.
- Connections: adjoining walls, docks, lifts, utilities and drainage.
- Approvals: application preparation, revisions and applicable start conditions.
- Construction: measured quantities, removal, installation and documented hidden-condition allowances.
NOAA says seawall projects will likely need a benthic survey. Ask whether that work is included before comparing two construction totals.
What should you ask before accepting a per-foot price?
Ask which wall length is measured, whether returns are included and how the quoted system was selected. Request separate lines for design, permits, demolition, access, wall installation, dock or lift work and restoration. A per-foot figure that excludes those items is not the final project budget.
Use your actual written prices in the planner. The site does not populate a Key Largo market rate from unrelated public projects or another city’s contractor advertisements.
Which amounts belong in your total?
| Category | Meaning | How to compare |
|---|---|---|
Included contract work | The defined work in the written base price. | Check quantities, drawings and exclusions match. |
Allowances / provisional items | A stated amount for work not fully defined. | Ask what changes it, how it is measured and how changes are approved. |
Owner-arranged costs | Survey, design, access, restoration or other work outside that agreement. | Obtain separate quotes and add them without counting included work twice. |
For example, one bid may include removing and reinstating a dock while another leaves that work to you. Obtain the missing amount before comparing the two totals. If it is still unpriced, label the comparison incomplete.

An inspection can help answer the questions you were unsure about.
An on-site inspection is needed to assess the wall’s condition. These answers help you explain what you have noticed.

What could your seawall cost?
Published Florida starting ranges, with the source area shown. Your Key Largo project needs a site-specific written quote.
Choose the work, wall length and material in the calculator to see a starting range. Repair project totals stay separate from per-foot construction and cap prices. Then use a property quote to add known extras and a reserve.
Repair prices by type
Compare prices for the same type and amount of work. A small repair and a full replacement cover different jobs.
| Work | Amount | What the price covers | Area and source |
|---|---|---|---|
Partial repair / scope not yet confirmed | $5,000–$30,000 | per project; Broad partial-repair project reference; the extent of work must be assessed. | Palm Beach and Broward counties, Florida [3] |
Crack injection and sealing | $2,000–$8,000 | per project; Targeted crack treatment; not a structural replacement or a whole-wall per-foot rate. | Palm Beach and Broward counties, Florida [3] |
Tieback anchor installation | $8,000–$20,000 | per project; Published tieback project reference. Anchor quantity, design and access need confirmation. | Palm Beach and Broward counties, Florida [3] |
Replace the concrete cap | $150–$350 | per foot of wall; Cap removal and replacement only; retained panels and supports require assessment. | South Florida: Palm Beach, Broward and Martin counties [4] |
Raise the concrete cap | $200–$400 | per foot of wall; Cap raising only, including forming, pouring and permit management in the source region. Structural strengthening, wall relocation and Keys approvals require separate review. | South Florida: Palm Beach, Broward and Martin counties [4] |
Construction and replacement prices per foot
New construction and replacement have separate references. Rates retain the publisher’s original area and scope. Neither source is a Key Largo price survey.
| Material / work | Price per foot of wall | Area, included work and source |
|---|---|---|
Vinyl replacement | $600–$1,000 | Palm Beach and Broward counties, Florida · Replacement reference. Verify removal, design, permits, access and restoration in the written scope. [1] |
Concrete replacement | $800–$1,400 | Palm Beach and Broward counties, Florida · Replacement reference. Verify removal, design, permits, access and restoration in the written scope. [1] |

Steel wall construction | $700–$1,000+ | Florida; Southwest Florida contractor · Construction reference. Demolition and other property-specific work can add to this amount. [2] |
50-, 75- and 100-foot examples
Multiply the wall length by the price per foot. These examples use wall length to show construction costs. Add any work not included in the price per foot.
| Material / work | 50 feet | 75 feet | 100 feet |
|---|---|---|---|
Vinyl replacement | $30,000–$50,000 | $45,000–$75,000 | $60,000–$100,000 |
Concrete replacement | $40,000–$70,000 | $60,000–$105,000 | $80,000–$140,000 |
Composite replacement | $50,000–$80,000 | $75,000–$120,000 | $100,000–$160,000 |
New vinyl wall | $20,000–$32,500 | $30,000–$48,750 | $40,000–$65,000 |
New concrete wall | $32,500–$45,000 | $48,750–$67,500 | $65,000–$90,000 |
New composite wall | $25,000–$40,000 | $37,500–$60,000 | $50,000–$80,000 |
Steel wall construction | $35,000–$50,000+ | $52,500–$75,000+ | $70,000–$100,000+ |
For example: 75 ft × $600–$1,000/ft = $45,000–$75,000. Check your wall length and what the price includes.
What to include in your price
Give every bidder the same brief and compare these items line by line.
- Existing-wall assessment and additional investigations
- Boundary/elevation survey and design responsibility
- Habitat or benthic resource assessment, if required
- County or Village permits and state/federal/sanctuary coordination
- Demolition, debris containment and disposal
- Equipment access, barge arrangements and staging
- Measured wall components, connections and materials
- Dock, boat lift, electrical and utility interfaces
- Drainage, backfill and landscape/paving restoration
- Required inspections, final records and warranty exclusions
How do you turn an estimate into a decision?
Fix the common scope
Use the same wall length, plan revision, access assumptions and restoration boundary for each bidder.
Resolve exclusions
Request a price or named responsibility for each necessary excluded item. Keep optional improvements separate.
Review the uncertainty
Ask what additional investigation could reduce an allowance and what changed conditions could increase it.
Record the complete comparison
Keep the written total, remaining unknowns, schedule assumptions and payment milestones beside each offer.
A fixed setup cost does not necessarily scale with wall length. Use the calculator for the quoted items it represents, then review its list of missing inputs before relying on the result.

How to use these prices
Calculator references were checked October 29, 2026: JKT Marine’s replacement, May repair and cap-work pages, and SeaBee’s Florida construction guide. Each rate retains its source, unit and work type. JKT publishes different ranges on other pages; these named tables are used separately, without blending them into a local average. Monroe County permit fees remain a separate budget item. No automatic Keys, height or access multiplier is applied.
