What seawall replacement costs in Boca Raton
A planning range from national cost guides, what pushes it up or down locally, and how to compare quotes so you are pricing the same job.
How much does seawall replacement cost in Boca Raton?
No Boca Raton-specific cost survey was found. National cost guides put seawall construction at roughly $200 to $600 per linear foot by material in 2026, with repair work running $100 to $250 per linear foot. On a 100 foot residential wall, that is commonly $15,000 to $60,000 for a full replacement, with national full-project averages around $35,000.
Treat these as a starting point, not a Boca Raton price. Use them to plan, then let written quotes on your actual wall set the real number.
What changes the price locally
- Meeting the elevation standard. A wall built to Boca Raton's 4.0 to 6.0 foot NAVD88 minimum, with room for a future 12 to 18 inch extension, uses more material than a lower cap did.
- Height and water depth. Taller walls in deeper water need longer panels and more engineering.
- Tiebacks and anchors. The anchoring system is a major part of the structure and the cost.
- Access. Equipment that can work from your yard is usually cheaper than a barge, but some lots only allow barge access.
- Demolition. Removing the old wall and disposing of it adds cost.
- Dock and lift. Removal and reinstallation can be a real line item.
- Engineering and permits. The city requires signed and sealed drawings, Army Corps of Engineers approval, and product approvals or NOA.
What should a seawall replacement quote include?
Before you compare totals, make sure each quote states:
- Linear feet of wall being replaced
- Wall material and specification
- Tieback type and spacing
- Cap dimensions and finished elevation, against the city's 4.0 to 6.0 foot NAVD88 range
- Demolition and disposal
- Dock and lift removal and reinstallation
- Engineering and permit fees, including who pulls the permit
- Warranty terms
- A payment schedule tied to completed milestones
Florida requires licensed contractors to put their registration or certification number on their bids and contracts. If it is missing, ask why.

The page lists meeting the elevation standard, wall height and water depth, tiebacks and anchors, yard versus barge access, demolition, dock and lift work, and engineering and permits. Two walls on the same canal can price very differently.
Does meeting the city's elevation rule add to the cost?
A wall built to the city's 4.0 to 6.0 foot NAVD88 minimum, with room for a future 12 to 18 inch extension, uses more material than an older, lower wall did. Ask your contractor how the standard affects your specific quote.
