DOCK CLEANING FAQs
How do you clean a marine dock?
Above the waterline, pressure washing clears algae, salt, and debris from deck surfaces. Below the waterline, a diver removes barnacles, oysters, and other growth from pilings and structural components using non-abrasive tools.
The Florida DEP emphasizes keeping dock structures maintained to protect both the property and the surrounding marine habitat. For a full walkthrough of the cleaning process above and below the waterline, read our guide: How Do You Clean a Marine Dock?
How often should a dock be cleaned in Florida?
Every two to four months is the general recommendation, with more frequent service during the summer when water temperatures peak and growth rates spike. Docks in shallow canals with limited water flow foul faster than those on open waterways.
The Florida Inland Navigation District identifies marine growth as a contributing factor in waterfront structure maintenance needs across the state’s east coast. For a detailed breakdown of what affects your cleaning schedule, read our guide: How Often Should a Dock Be Cleaned in Florida?
Can barnacles damage a dock?
Yes. Barnacles trap moisture and salt against dock surfaces, which causes rot in wood, spalling in concrete, and accelerated corrosion in metal components.
The University of Florida’s Sea Grant program identifies marine organism fouling as a contributing factor in coastal infrastructure degradation. Routine dock cleaning prevents this damage and costs a fraction of the structural repairs that result from neglect.

How much does dock cleaning cost?
Pricing depends on dock size, number of pilings, and how much growth has accumulated. A dock on a regular cleaning schedule costs less per visit than one with heavy, hardened fouling. The Marine Industries Association of South Florida identifies routine waterfront maintenance as the most cost-effective way to preserve property value along the coast.

What is the best way to remove algae from a dock?
Pressure washing at 1,500 to 2,500 PSI with a wide-angle nozzle handles most surface algae on dock walkways. Below the waterline, algae forms the biofilm layer that barnacles settle on, so removing it regularly is the best way to prevent heavier fouling.
The Florida Fish and Wildlife Conservation Commission provides resources on algae species common in state waters, many of which are the same ones that colonize dock surfaces.
