Birds perch on the pilings and the rails. Fish cleaning stations leave blood, scales and oil that bake in the sun. Shaded boards under the boat lift canopy stay damp and turn green and black. All of it makes the walking surface slick. Seawall caps get the same mix along with mower clippings and sprinkler rust from the yard side. The upper face of the wall, above the tide line, grows dark algae streaks. Cleaning the cap and the visible face makes the waterfront look kept and lets you see the condition of the concrete. The big difference from any other job is the water. Runoff from a dock or seawall goes straight into the canal. That shapes every choice we make. We lean on hot water and scrubbing, use only small amounts of cleaner where it is truly needed, and keep soft wash solution off surfaces that drain directly into the water. Pressure is the other concern. Wood dock boards splinter under a narrow tip. Seawall joints and weep holes should not be blasted, because forcing water into them can wash out fill behind the wall. We keep the nozzle wide and the pressure moderate on both. ![Waterfront dock surface before and after cleaning in Naples FL](https://naples-pressure-washing.com/wp-content/uploads/2026/07/Before-and-After.webp)Docks are cleaned with hot water and brushes to keep chemical out of the canal.Boat on the Lift?Please raise the boat or move it before we arrive so spray and drips do not land on the hull or canvas. We do not wash boats. 💧 How We Clean Docks and Seawalls Our Method ![Choosing safe water pressure for wood and concrete surfaces](https://naples-pressure-washing.com/wp-content/uploads/2026/05/Water-Pressure-Myths-That-Ruin-Stucco.webp)Wide tips and moderate pressure protect dock boards and seawall joints.Wood docks get a hot water wash with a wide fan tip, moving with the grain at low to moderate pressure. Bird droppings and fish residue are pre-soaked with hot water and brushed off. Where mildew is heavy and the boards drain onto land or a deck, we may use a small amount of oxygen-based cleaner. Composite docks get hot water and soft brushes. The textured surface holds algae, so brushing matters more than pressure. We clear the gaps between boards so leaves and dirt do not hold moisture. Concrete docks and seawall caps can take a surface cleaner with hot water. It gives an even finish and contains the spray. Rust from yard sprinklers on the cap is spot treated and rinsed toward the lawn side, away from the water. We finish with a walk of the dock and wall, pointing out loose boards, popped fasteners, cracked caps or gaps at the wall joints. We do not repair docks or seawalls, but you will know what to show your marine contractor. | Surface | Common Buildup | Method | | ------- | -------------- | ------ | | Wood dock boards | Algae, bird droppings, graying | Hot water, wide fan tip, brush | | Composite dock boards | Algae in texture, salt film | Hot water, soft brushes, gap clean-out | | Concrete dock | Algae, fish residue, stains | Hot water surface cleaner | | Seawall cap | Algae, clippings, sprinkler rust | Surface cleaner, rust spot treatment | | Seawall face above tide | Dark algae streaks | Hot water, moderate pressure, joints avoided | 🌊 What We Clean on the Water Surfaces Docks ### Fixed docks and walkways Main dock decks, walkways from the yard and steps down to the water.
