SEAWALL CLEANING FAQs
How do you clean dock pilings?
A diver works around each piling from the waterline to the mudline, removing barnacles, oysters, and algae using non-abrasive tools matched to the piling material.
The Florida DEP includes piling condition in its dock maintenance guidance, recognizing that structural integrity depends on what’s happening below the waterline. Every cleaning also serves as a visual inspection that catches early signs of rot, cracking, or corrosion.

Why do pilings need to be cleaned?
Marine growth traps moisture against piling surfaces, which promotes rot in wood, crack expansion in concrete, and accelerated corrosion in metal.
The University of Florida’s School of Forest, Fisheries, and Geomatics Sciences identifies marine borer activity as a leading cause of wood piling failure in Florida’s coastal structures.
Regular cleaning removes the conditions that drive deterioration and gives a diver repeated opportunities to catch early signs of damage. For a detailed look at how fouling affects each piling material, read our guide: Why Do Pilings Need to Be Cleaned?
How often should dock pilings be cleaned?
Every one to three months in warm saltwater, with more frequent service for wood pilings and locations with minimal water flow.
The South Florida Water Management District monitors nutrient levels in coastal waterways, and elevated nutrients contribute to faster biofouling on submerged structures like pilings. Cleaning on the same schedule as your dock and seawall keeps everything maintained in one visit.

Can barnacles damage dock pilings?
Yes. Barnacles trap moisture against pilings, accelerating rot in wood, crack expansion in concrete, and corrosion in metal. On wood pilings, barnacle colonies also create habitat for marine borers that hollow out the interior.
The Florida Department of Agriculture and Consumer Services recognizes marine borer damage as a concern for treated wood in coastal construction. Regular cleaning removes the conditions that drive this deterioration.

How much does piling cleaning cost?
Pricing depends on the number of pilings, their depth, and how much growth has accumulated. Pilings on a regular schedule cost less per visit than those with heavy, hardened fouling.
The Broward County Board of County Commissioners has funded waterfront infrastructure projects that highlight how expensive piling replacement is compared to preventive maintenance. Bundling piling service with your dock, seawall, and lift cleaning reduces cost further.
