Is Soft Washing Safe for Caldwell Homes?

Soft washing is safe, and in Caldwell it is the method that actually addresses the local problem. After a long Canyon County fog season, the growth on north-facing walls is living organic material, and that responds to chemistry rather than to force.

Algae needs killing, not blasting

Organic growth has a root structure in the surface. Pressure removes what is visible while leaving what regrows, which is why blasted walls green up again quickly. Soft washing at $0.18 per square foot treats the growth itself, so the result lasts considerably longer.

Pressure on a damp wall is worse here

In a region where walls stay saturated for weeks, forcing more water into the cladding is the last thing a north elevation needs. That is the specific reason high pressure is a poor idea in Caldwell rather than merely a general one.

Surfaces that do take pressure

Driveways, patios and walkways are cleaned with genuine pressure at $0.20 per square foot. The distinction is always the surface, and a company using one approach for everything is not making that distinction.

Timing matters more than method

Doing this in fall, before the wet season, means the growth goes into winter cleared rather than fed. The same work in March is harder and the result is shorter-lived.

Is soft washing safe for my siding?

Yes. It cleans at low pressure using chemistry rather than force, which is safe for vinyl, stucco, hardie and painted surfaces.

Why does pressure washing not fix algae permanently?

It removes what is visible while leaving the root structure, so the growth returns quickly. Soft washing treats the growth itself.

Is pressure worse on a damp wall?

Yes. In a long fog season the wall is already saturated, and forcing more water in is the last thing it needs.

What does it cost?

House washing is $0.18 per square foot; flatwork pressure washing is $0.20 per square foot.

When should it be done?

Fall, before the wet season, so growth goes into winter cleared rather than established.
