Seawall Cost Estimator

Vinyl, concrete, aluminum, or rip-rap — get a Tampa Bay estimate per linear foot including tiebacks, cap, and county permit fees.

How it works

Seawall cost, honestly

Cost scales linearly with length and disproportionately with retained height. Every foot over 6 ft of retained height adds ~8% to the wall cost.

Any seawall over 6 ft of retained height needs tiebacks — helical anchors are the modern standard in Tampa Bay. Skipping them is how walls fail.

Take the breakdown above to 2–3 vetted local contractors. Wildly different numbers on the same spec usually mean one of them is skipping something.
