Is soft washing just weak pressure washing?

No. Soft wash is low pressure plus a cleaning solution that has time to work. The pressure is not reduced because the operator is being cautious — the detergent is what removes the growth, and pressure was never doing that job.

Can you pressure wash a house if I ask you to?

We will not blast siding, because it damages paint and forces water behind panels. If a surface genuinely needs force — concrete, paving — that is exactly what we use there. The choice follows the material.

Duration depends on the surface and how much moisture and shade it gets, not on the method. A shaded north wall in this valley will grow again sooner than a sunlit one no matter which method cleaned it.

Is soft washing safe around plants?

With the practice done properly — beds saturated before, rinsed after, product diluted — yes. Detergent left to sit on dry foliage undiluted is what causes damage, which is why the wetting-down step matters.

These are two different tools for two different problems. Most damage done to exteriors is a method mismatch, not a bad operator.

Definitions in plain English

Soft wash: low pressure, biodegradable detergent, and dwell time. The chemical does the cleaning; the water rinses.
Pressure wash: high-pressure water, sometimes with heat or detergent, used where a surface is hard enough to take force.
The difference that matters is not which is stronger — it is which one the surface can survive.
One property regularly needs both: soft wash on the siding, pressure on the driveway.

Which method for which surface

Surface	Preferred method	Risk if the wrong one is used
Painted wood / fiber-cement siding	Soft wash	Paint film abraded, chalking, premature repaint
Vinyl siding	Soft wash	Water forced behind panels, staining and trapped moisture
Asphalt shingle roof	Soft wash only	Granules stripped, shingle life cut short
Concrete driveway	Pressure + surface cleaner	Detergent-only leaves embedded dirt and moss base
Pavers	Pressure, then re-sand	Joints washed out, pavers shift, weeds return
Wood deck or fence	Soft wash, wood-safe	Grain furred, sealer stripped, rot at joints
Boat hull / RV gel coat	Soft wash + hand detail	Gel coat scratched and dulled
Brick and stone	Soft wash	Mortar and surface eroded over repeat visits

Why "more PSI" is not more professional

Pressure is the easy variable to advertise and the easiest way to cause damage.
A machine that removes growth without removing surface is the one doing the skilled work.
Etching on concrete, furring on wood, and streaks on siding are all the same failure: force applied where it did not belong.
The cleaning in a soft wash happens during dwell time, which cannot be rushed by turning the pressure up.
If a quote leads with PSI rather than with method-matching, that tells you what the work will be.

Chemical and dwell-time myths

"It's just soap, so it can't do anything." Detergent is doing the cleaning in a soft wash — the water is only the rinse.
"Stronger is better." Over-strength mix on the wrong surface strips paint and burns foliage; dilution matched to the substrate is the point.
"Spray it and rinse it straight off." Removing growth requires letting the product sit. Rinsing immediately is why some washes look no different afterwards.
"Bleach kills everything, so it's the answer to moss." Moss regrows unless the moisture condition and debris are dealt with, and there is a reason it likes that specific wall.
"It's safe because it's biodegradable." It is safer than the alternative, and it still needs wetting down and rinsing around plant beds rather than being left to sit.

When we mix methods on one property

A standard house-and-driveway job is both methods on the same visit: soft wash up top, surface cleaner on the concrete.
Decks and fences under a house wash get the wood-safe approach while the siding above takes standard soft wash.
Roof surfaces, if cleaned at all, are soft wash only — pressure on a shingle roof shortens its life.
We change method at the boundary between materials rather than treating a property as one surface.
