Home › Soft Washing
The professional-grade alternative to jet washing. Low pressure, biocide-based, kills algae and moss at the root. No surface damage, no stripped tiles, no broken ridge mortar.
Soft washing is the application of biocide cleaners at very low pressure (typically under 100 psi — about the same as a garden hose). The biocide kills the algae, lichen and moss spores at their root. The dead growth is then either rinsed away or left to weather off naturally over a few weeks.
The contrast with high-pressure jet washing is significant. Jet washers physically blast surfaces clean — effective in the short term, but they also strip protective glazes off concrete tiles, crack ridge mortar, force water under sealed surfaces, and leave moss spores in place to regrow within a year. Soft washing, properly done, produces results that last 5–7 years.
Jet washing: instant results, strips protective surfaces, regrowth within 12 months, can crack mortar and break tile seals.
Soft washing: 24–48 hour visible improvement, no surface damage, 5–7 year regrowth window, safe on every common exterior material.
Soft wash pricing is broadly similar to traditional cleaning — sometimes slightly cheaper because we don’t need scaffolding or heavy lifting equipment.
