Soft Washing vs Pressure Washing in Antioch, CA
Pressure washing uses high PSI to scour hard surfaces like concrete. Soft washing uses low pressure and a sodium hypochlorite detergent to kill growth on siding, stucco, and roofs. In Antioch you need both, because the Delta feeds algae on walls while wind grit packs into flatwork.
Where high pressure belongs
Driveways, sidewalks, patios, curbs. Hard flatwork takes high pressure well, and nothing else removes ground-in grit and tire marking as effectively. Antioch concrete collects wind-blown Delta dust constantly, so surface cleaning with real pressure is the right call there. That is the full list. If a surface is not hard flatwork, high pressure is the wrong tool.
Where soft washing takes over
Siding, stucco, roofs, fences, screens. The green and black growth on these surfaces is biological, fed by river humidity, and pressure just smears it while damaging the surface. High pressure forces water behind wood siding on older 94509 homes, etches stucco in 94531, and strips shingle granules outright. Soft washing kills the organisms with detergent at garden-hose pressure, so it stays clean far longer.
Why the distinction matters when you hire
Plenty of damage we see in Antioch came from a rented machine or a low-bid operator using one high-pressure setting on everything. Etched stucco lines and fuzzed wood grain are permanent. Ask any washer you are considering which surfaces they soft wash. If the answer is none, keep looking. We bring both systems to every job and choose per surface.
Questions We Actually Get
Is soft washing just weaker pressure washing?
No. It is a different system built around detergent doing the work. The sodium hypochlorite mix kills mildew and algae at the root, which plain pressure at any strength cannot do.
Which does my Antioch home need?
Almost certainly both. Concrete gets pressure, the house body and roof get soft wash. We quote them together so the whole property is handled in one visit.
Will soft wash detergent smell or leave residue?
There is a mild chlorine scent during the work that fades within hours. We rinse all surfaces and landscaping thoroughly, so nothing sticky or filmy is left behind.
