Cleaning a typical residential dock in Cape Coral costs about $150–$400, depending on its size and decking. Wood and composite docks are soft washed; concrete cantilever docks and seawall caps are pressure washed. Seawalls are quoted after a look, because length and access from the yard vary so much from lot to lot.
Why canal docks get so slippery
Docks on the Cape's canals sit low and close to the water, often under a boat lift canopy or beside mangroves, so they get very little drying time. Algae and mildew settle into the grain of wood boards and the texture of composite, and after a rain it can be as slick as ice. A clean dock is first of all a safety job: it is where people step on and off boats.
Matching the method to the decking
Wood
High pressure raises the grain and leaves wood fuzzy and splintered. We soft wash pressure-treated boards, scrub where needed and rinse gently.
Composite
Composite boards can be scarred by a close tip and their cap layer worn through. Same approach as wood: solution, brush, low rinse.
Concrete docks and seawall caps
Concrete can take a surface cleaner, which is the only way to get an even result on a wide cantilever dock or the top of the wall.
Working beside the water
Everything on a dock drains straight into the canal, so the rules are tighter here than on a driveway. Lee County prohibits discharges into waterways and anything connected to them, and Cape Coral's canals are part of that system. We keep chemistry to what the job needs, apply it from the land side, avoid overspray onto the water and never rinse cleaning residue off the edge on purpose. Boat lift motors, electrical boxes and cushions are covered or worked around.
Pairing it with the rest of the back yard
Most canal-front owners book the dock with the pool cage and the walkway down to the water. One setup, one visit, and the whole path from the lanai to the boat is clean at the same time.
What dock and seawall cleaning costs
| Job | Estimated price | What moves it |
|---|---|---|
| Typical residential dock | $150–$400 | Size, decking material, how slick it is |
| Concrete cantilever dock | From $150 | Width and length |
| Seawall cap and face | Quoted on site | Length and whether it can be reached from the yard |

Dock and seawall cleaning questions
Do you clean from a boat?
No. We work from the dock and the yard. Seawall faces that can only be reached from the water are outside what we do.
Will cleaning harm the canal?
We use the least chemistry that will do the job and apply it away from the water. Wood and composite are soft washed, which uses far less runoff than blasting.
Can you clean the boat lift?
We rinse the lift frame and the canopy underside along with the dock. The motor and cables are left alone.
