How much does it cost to replace a seawall?

Seawall replacement in South Florida typically costs $500 to $2,000 per linear foot depending on the material and site conditions. A 100-foot seawall replacement could cost $50,000 to $200,000. That is why a pre-purchase inspection is so important for waterfront properties.

How long do seawalls last in South Florida?

Concrete seawalls generally last 30 to 50 years, steel sheet pile walls last 25 to 40 years, and vinyl or composite walls can last 50 or more years. Actual lifespan depends on water conditions, maintenance, soil type, and exposure to storms and wave action.

What are signs of a failing seawall?

Warning signs include visible cracking or separation, tilting or leaning, sinkholes or depressions in the yard near the wall, exposed soil behind the cap, rust stains from corroding steel, and water seepage through the wall face. If you notice any of these, schedule an inspection promptly.

Does homeowners insurance cover seawall damage?

Standard homeowners insurance policies rarely cover seawall damage or deterioration. Some policies exclude seawalls entirely. Flood insurance may cover sudden damage from a covered event but not gradual deterioration. Review your policy carefully and budget for seawall maintenance separately.

Seawall Inspection

Assess seawall structural integrity, erosion, and drainage for waterfront properties.

Seawall inspections are essential for waterfront property buyers and owners in South Florida. A failing seawall can cost $500 to $2,000 per linear foot to replace, making it one of the most expensive repairs a homeowner can face. Knowing the condition of a seawall before purchasing a waterfront property can save you tens of thousands of dollars.

Our inspectors evaluate the seawall from both the land side and the water side (where accessible), checking for structural cracking, tilting or displacement, erosion behind the wall, cap condition, tiebacks, return walls, and drainage systems. We also look for signs of soil loss, sinkholes near the wall, and vegetation damage that may indicate subsurface problems.

South Florida's marine environment is particularly harsh on seawalls. Salt water, tidal action, storm surge, and boat wake all contribute to deterioration over time. Even concrete and steel seawalls have a limited lifespan and require regular maintenance to remain structurally sound.

Visual structural assessment from land and water sides
Crack mapping and displacement measurement
Cap and coping condition evaluation
