Soft washing vs pressure washing: which is right for your property?
Updated 6 November 2026 · By the Soft Wash team
Short answer: Soft washing uses low pressure and a biocide to kill algae, mould and lichen, so it is the right choice for render, roofs, painted walls, cladding and soft brick or stone. Pressure washing blasts dirt off with high-pressure water and suits hard surfaces such as concrete and block paving, but it can damage softer surfaces and growth tends to return sooner.
Side-by-side comparison
| Soft washing | Pressure washing | |
|---|---|---|
| Pressure | Low, similar to a garden hose | High |
| How it cleans | Biocide kills growth, then rinsed | Water force strips the surface layer |
| Best for | Render, roofs, cladding, painted and soft masonry | Concrete, block paving, hard patios |
| Risk of damage | Low when done properly | Can erode render, stone and pointing |
| How long it lasts | Usually several years | Growth often returns sooner |
When soft washing is right
- Rendered or painted walls
- Roofs with moss, lichen or algae
- uPVC, composite or timber cladding and fascias
- Older brick and natural stone
When pressure washing is right
- Concrete driveways and paths
- Block paving and hard patio slabs
- Heavy mud or ground-in dirt on hard, durable surfaces
Many jobs use both: soft washing for the walls and roof, and pressure washing for the drive and patio.
