Soft Washing vs Pressure Washing: What Your Siding Actually Needs

Not all exterior cleaning is created equal. Pressure washing and soft washing look similar from the driveway, but they're two very different tools — and using the wrong one on your house can cost you thousands in repairs.

Pressure washing: high pressure, water only

Pressure washing uses a high-PSI stream of water to physically blast dirt off a surface. It's the right choice for:

• Concrete driveways and sidewalks
• Paver patios
• Brick walkways
• Fences and decks (at lower pressure)

What it's not good for: vinyl siding, painted wood, stucco, older mortar, or anything with a seal that water can force behind. High pressure on siding can crack panels, drive water into your wall cavity, and strip paint.

Soft washing: low pressure, cleaning solution

Soft washing uses a gentle, low-pressure spray combined with a biodegradable cleaning solution that kills algae, mildew, and mold at the root. It's the right choice for:

• Vinyl, aluminum, and cedar siding
• Stucco and EIFS
• Roof shingles
• Painted trim and soffits

The solution does the work — not the pressure. That means no cracked panels, no forced-in water, and results that last 4–6 times longer than pressure alone, because you've actually killed the organic growth instead of just blasting it off the surface.

The rule of thumb

Hard surfaces = pressure. Anything attached to your house = soft wash.

When we quote a house wash, we're almost always talking about soft washing the siding and pressure washing the concrete around it — two tools, one clean property.
