What is the difference between pressure washing and soft washing?

Pressure washing uses high-pressure water to blast dirt off hard surfaces like concrete. Soft washing uses low pressure — about the strength of a garden hose — with cleaning solutions that kill algae and mold on delicate surfaces like siding and roofs.

Can you pressure wash a house?

High pressure should not be used on siding, stucco, or roofs — it forces water behind the siding and damages the surface. Those surfaces are soft washed instead. Concrete, brick, and pavers are pressure washed.

Pressure Washing vs Soft Washing: What's the Difference?

Pressure washing and soft washing solve different problems with different methods. Here's which surface needs which — and why the wrong choice damages your property.

These two terms get used interchangeably, but they're completely different methods — and using the wrong one on a surface can cause real damage. Here's the difference and when each is the right choice.

Pressure washing: high pressure for hard surfaces

Pressure washing uses high-pressure water — typically 2,500–4,000 PSI — to physically blast dirt, grime, and stains off durable, hard surfaces. It's the right method for concrete driveways, brick, pavers, and stone. The pressure does the work.

Soft washing: low pressure with chemistry for delicate surfaces

Soft washing uses very low pressure — about the strength of a garden hose — combined with specialized cleaning solutions that kill algae, mold, and mildew at the source. It's the safe method for vinyl siding, stucco, brick walls, painted surfaces, and especially roofs. The chemistry does the work, not the pressure.

Why the wrong method causes damage

High pressure on siding forces water behind the walls, causing rot and mold
High pressure on stucco can crack and chip the surface
High pressure on a roof strips the protective granules off asphalt shingles
Low pressure on heavily stained concrete simply won't clean it

How we choose

On every property, we match the method to each surface. Your driveway gets pressure washed; your siding and roof get soft washed. That's why a professional assessment matters — the wrong choice is expensive.
