Exterior cleaning Riverbank: two problems, two elevations

Riverbank homes usually need two different treatments on the same house. The bluff-facing side takes dry wind grit and looks dull and sandy; the river-facing and shaded sides hold fog moisture and grow algae. Treating both with one recipe is why so many local washes disappoint.

The bluff side is abrasive, so nothing gets scrubbed

Wind grit on Riverbank's bluff-facing walls is floated away with water volume, because scrubbing it grinds the finish.

This side of the house rarely looks dirty in the classic sense — it looks flat and sandy. The grit is sitting in the texture, and any contact cleaning drags it across the surface.

We flood, dwell and rinse. On dark trim and glass we follow with purified water so the drying stage does not leave its own marks.

The river side is biological

Overnight fog off the Stanislaus feeds algae on Riverbank's shaded and river-facing walls, fences and roof slopes, all of which need a treatment that kills.

Green algae takes hold first, black mildew follows. Neither is removed by rinsing off the colour — the organism has to be killed or it recolonises within weeks.

Roof slopes on this side are worth watching. Algae holds moisture against the shingle, so treating it is protective, not just cosmetic.

Santa Fe District and Terminal Avenue frontages need more frequency

Riverbank's older Santa Fe District homes and the Terminal Avenue business frontages soil faster and benefit from a shorter cleaning cycle.

Older finishes hold dirt more readily, and commercial frontages take pedestrian and traffic film on top of everything the weather delivers.

For those addresses we suggest a mid-year touch on glass and the street elevation, with the full exterior handled annually. Residential streets in Del Rio, Crossroads and Riverbank Heights hold up well on a single yearly visit.

On river-facing and shaded slopes, yes. Algae keeps moisture against the shingle, which shortens roof life as well as looking poor.
