Docks, seawalls and waterfront decks
Canals and the Intracoastal give many properties a dock, a seawall or a boat lift. Wood and composite docks turn slick with algae, and concrete seawalls develop green and black staining at the waterline. Slippery boards are a safety risk and a nuisance for anyone stepping off a boat.
Cleaning near water brings its own rules. Cleaners must be chosen with care so they do not harm the water or the marine life nearby, and runoff should be kept off the sea side as far as possible. The crew plans the work to keep chemicals contained and to rinse thoroughly.
