Seawall and Dock Contractors in Lee County

Seawall and dock contractors in Lee County work the largest canal system in the world, and in Cape Coral a seawall is not optional.

Licensed Permits handled Florida waterfront

We connect waterfront homeowners from Cape Coral to Matlacha with licensed marine contractors who work those canals every week.

The inspection is free and you get a written estimate before anyone touches your property.

Cape Coral requires a seawall, and sets the numbers

Cape Coral’s marine improvements code requires property with saline or brackish frontage to have seawalls bulkheading the entire frontage, at the owner’s expense. Freshwater frontage requires a seawall or an approved vertical bulkhead alternative.

The code is specific about the rest too: decking may not sit more than two feet above the seawall cap, or four feet on the Caloosahatchee and nearby canals; pilings may not exceed ten feet above the cap; a structure may not project more than 25% of the waterway width or thirty feet, whichever is less. Concrete marine improvements must be designed and sealed by a Florida registered professional engineer, which is a real line item on a replacement.

The 50% rule, and why it does not apply to your seawall

It is the most asked question on Cape Coral seawall searches, and the answer is not what most owners assume. The FEMA 50% rule is a flood-insurance requirement: if work on a non-conforming building costs 50% or more of that building’s market value, the building must be brought into current floodplain compliance.

The ratio is the cost of work divided by the market value of the building. Guidance is explicit that it applies to the value of the building or structure, not the total value of the property, which may also include the land, landscaping, seawall, dock, pool or other site improvements.

So seawall work does not count toward your 50% threshold, and the rule does not force a seawall replacement. Confirm your own numbers with the City of Cape Coral.

Why it matters

Freshwater and saltwater canals fail differently

About half of Cape Coral’s 400-plus miles of canals are freshwater and landlocked: no tidal cycle, no salt reaching the reinforcement. Gulf-access and saltwater spreader canals are tidal and saline, and they age faster.

The Chiquita Lock was permanently removed in June 2025, so canals that used to route through it now run straight to the Caloosahatchee and fixed bridges decide access. Hurricane Ian impacted at least 52,514 structures across Lee County in September 2022.

A free inspection tells you which one you are looking at.
