Palo Alto's mature tree canopy and the Bay Area's persistent coastal fog create consistently shaded, damp conditions on horizontal surfaces — exactly what mold, algae, and organic film need to establish on concrete, pavers, and stone. North-facing patios and walkways under tree cover can go from clean to heavily filmed in a single wet season. The foot traffic that follows grinds the biological growth into the surface pores, making it harder to remove over time.
Poured concrete, broom-finished concrete, exposed aggregate, concrete pavers, brick pavers, natural stone (flagstone, travertine, bluestone), and decomposed granite borders. Each surface type is cleaned at appropriate pressure — exposed aggregate and natural stone at lower pressure than poured concrete to avoid surface damage.
Green and black algae film, moss, mold, mildew, general dirt, tire marks, light rust staining, and organic buildup from leaves and debris. Heavy oil stains may require a separate degreaser application. We'll assess during the quote and set accurate expectations before starting.

Surface type, buildup level, and any staining mapped before we start. Paver joint condition checked — deep joint sand can be disturbed by very high pressure, and we adjust technique accordingly.
Furniture and planters moved. Drains confirmed clear. Nearby plants and landscaping pre-wetted. Run-off path checked to prevent dirty water reaching sensitive garden areas or neighboring properties.
Heavily soiled or organically stained areas pre-treated with appropriate solution before pressure washing. Dwell time held for the solution to penetrate and break up biological growth at the surface level.
Surface washed at pressure matched to the material. Concrete pavers and stone at lower pressure than poured slabs. Consistent overlapping passes — no streaking, no missed sections between panels.
Perimeter edges, expansion joints, and border areas hand-cleaned. Corners and areas behind fixed items where the wand can't reach addressed with detail tools.
Full area rinsed down. Surface checked for any remaining spots or missed sections before we leave. Furniture returned to position.

Concrete, pavers, natural stone, flagstone, travertine, and exposed aggregate. Pressure is adjusted for each material — softer surfaces like travertine are cleaned at lower pressure than poured concrete.
Palo Alto's mature tree canopy creates shade and the Bay Area's coastal fog keeps surfaces damp through the morning. North-facing and tree-shaded areas are especially susceptible to algae film buildup.
Pressure washing removes organic buildup and light staining effectively. Heavy oil stains require a degreaser treatment in addition to pressure washing. We'll assess and advise during the quote.
Yes. Pavers and flagstone are cleaned at lower pressure than poured concrete to protect joint sand and surface finish.
Most residential jobs take 1 to 3 hours depending on square footage and buildup level.
