Soft Washing vs Pressure Washing in Discovery Bay, CA
High-pressure washing scours hard flatwork like driveways and dock concrete. Soft washing pairs low pressure with sodium hypochlorite detergent to kill growth on stucco, roofs, and fences. Discovery Bay properties nearly always need both, chosen surface by surface.
The pressure list and the soft list
Pressure: driveway, walkways, patio slabs, pool deck, curb, and sound dock concrete. These surfaces are dense enough to take high PSI, and nothing else lifts embedded grit and tire scrub as well. Soft wash: stucco walls, any roof, painted or stained fences, screens, and patio covers. On those, growth is the real problem, and detergent kills it while pressure would only smear it and scar the surface.
Where Discovery Bay makes it interesting
Waterfront surfaces blur the lines. Dock decking might be composite, hardwood, or concrete, each with a different pressure ceiling. Seawall caps take pressure; the algae band at the waterline responds better to treatment first, then a controlled rinse. Hard-water scale on stucco needs a mineral dissolver, since neither pressure nor standard soft wash detergent touches it. Reading the surface correctly is most of the job here.
The cost of getting it wrong
We regularly see stucco with permanent wand etching and composite decking fuzzed by a rented machine turned up too high. Those surfaces cannot be un-damaged. Before hiring anyone, ask one question: which of my surfaces will you soft wash? A company that plans to pressure-blast everything is a company shopping for your HOA to notice etch marks next. We choose the method per surface, every time.
Questions We Actually Get
Which method cleans my dock?
It depends on the decking. Concrete takes pressure, hardwood takes reduced pressure with the grain, and composite takes low pressure with cleaner. We identify the material and match the method.
Why not soft wash everything to be safe?
Soft washing cannot lift grit ground into concrete, so flatwork would stay dingy. Each method exists because the other fails at its job.
Is sodium hypochlorite safe near the water?
Applied correctly, yes. We control dosing, keep application away from open water, and rinse to landscape or hardscape, never toward the bay.
