What Is Water Blasting?
Water blasting is the use of high-pressure or soft-pressure water to clean surfaces safely and efficiently.
It’s ideal for:
- Removing built-up dirt, grime, and salt deposits
- Blasting away moss, lichen, and algae
- Preparing surfaces for painting or sealing
- Restoring surfaces to like-new condition
✅ Proper technique matters:
- High pressure for driveways, patios, decks (hard surfaces)
- Soft washing (low pressure + chemical treatment) for delicate areas like roofs and walls
Common Areas That Need Water Blasting in Auckland
| Area | Why It Needs Cleaning |
|---|---|
| Roofs | Remove moss, lichen, salt deposits |
| House Exteriors | Clear mould, algae, grime |
| Gutters | Clear blockages and staining |
| Driveways and Paths | Remove oil stains, moss, black marks |
| Decks and Fences | Lift slippery growths and weathering |
| Retaining Walls | Clean dirt buildup, plant growth |
✅ Auckland’s coastal air and frequent rain accelerate surface buildup, making regular water blasting essential.
Why Water Blasting is Essential in Auckland’s Climate
| Weather Factor | Cleaning Need |
|---|---|
| Salt Spray | Rust, corrosion, paint damage |
| Heavy Rain | Moss, algae, lichen thrive |
| Strong UV | Paint and cladding breakdown |
| Humidity | Mould, mildew growth on walls |
✅ Annual or biannual water blasting protects exterior surfaces from this environmental wear.

High pressure can:
- Crack tiles
- Strip roofing membranes
- Cause leaks
At Metro Water Blasting, we use gentle soft wash methods and moss treatments to:
