Exterior cleaning Lathrop: new stucco, levee air and construction dust
Lathrop reads differently to the rest of our service area because so much of it is under ten years old. River Islands and the newer 95330 tracts have tight, uncured-feeling stucco, dark trim that shows every water spot, and lots of ongoing construction throwing fine silt across finished streets.

Short answer
Lathrop's dominant issues are construction silt on new stucco, humidity-fed algae on levee-facing walls and fences, and water spotting on the dark trim common in River Islands. New builds want gentle soft washing and purified-water glass work, not high pressure on young finishes.

Build my estimateConstruction silt behaves like sandpaper if you scrub it
Fine Lathrop build-site silt should be flooded off with volume at low pressure, because scrubbing drags grit across new paint and stucco.
Silt from graded lots travels a long way on afternoon wind and settles into stucco texture and window tracks. It is abrasive. Any process that presses it against the surface — a brush, a high-pressure wand — polishes scratch patterns into the finish that only show up later in raking sunlight.
We flood instead: plenty of water, plenty of solution, very little pressure, working downward so the grit leaves the wall rather than migrating across it.
Levee-side humidity feeds algae before it feeds mildew
Walls, fences and north-facing River Islands elevations near the water grow green algae first, which needs a dwelling treatment to kill rather than blast off.
Proximity to the San Joaquin and the levee system keeps overnight humidity higher in Lathrop than a few miles inland. Green algae colonises fence boards, the base of stucco walls and shaded siding well before classic black mildew shows up.
Blasting it removes the colour and leaves the organism. A treatment that dwells kills it, which is the difference between a wall that stays clean for a year and one that greens up again within a season.
Dark trim and big glass are where Lathrop homes look dirty
The dark fascia, garage doors and tall glass typical of Lathrop builds show every mineral spot, so purified-water finishing matters more here than anywhere else we work.
A white spot on cream trim is invisible; the same spot on charcoal trim reads from the street. That is why we run a purified-water final rinse on glass, frames and dark surfaces in Lathrop by default rather than as an upgrade.
Add gutter faces to the same visit while ladders are already set: on dark fascia the vertical tiger-striping is often the single most visible defect on the elevation, and as an add-on it is priced well below a standalone call-out.
