What Factors Affect Seawall Repair Cost?
Linear footage is the biggest cost driver. A 50-foot seawall costs significantly less than a 200-foot seawall. Most residential seawalls in Palm Beach and Broward County run 50 to 150 linear feet.
Severity of damage matters too. Localized cracks caught early can often be repaired for a few thousand dollars. A seawall neglected for years may require full replacement. Early action almost always saves money.
Permitting adds $1,500 to $6,000 depending on scope. Seawall work requires permits from local building departments and often SFWMD, FDEP, and Army Corps of Engineers. JKT Marine handles all permitting in-house — you never deal with agencies directly.
Repair vs. Replace
At JKT Marine, our rule is simple: repair when possible, replace when necessary. We never recommend full replacement just to increase a job's value. Signs replacement is necessary include multiple panels failing, seawall exceeding its 30 to 50 year lifespan, or repair costs exceeding 70% of replacement cost.
How Long Does Seawall Repair Take?
Permitting takes 2 to 6 weeks. Localized repairs take 1 to 3 days on site. Full replacement takes 1 to 3 weeks on site. Total timeline is typically 4 to 10 weeks from contract to completion.

Frequently Asked Questions
Do I need a permit to repair my seawall in Florida? Yes. All seawall repairs require permits. JKT Marine handles all permitting on your behalf.
How long does a seawall last in South Florida? A properly built concrete seawall lasts 30 to 50 years. Vinyl and composite seawalls can last 50 or more years.
What happens if I ignore a cracked seawall? Small cracks allow water to erode the soil behind the wall. What costs $5,000 to fix today can cost $80,000 or more if left unaddressed for a few years.
Can seawalls be repaired without full replacement? Yes in many cases. Crack injection, cap replacement, and tieback anchors can extend a seawall's life by 10 to 20 years at a fraction of replacement cost.
