If you live in Hamilton, you’ve probably noticed it — the yellow film of pollen on your windowsills, the green streaks on south-facing walls, the damp smell after it rains.
That buildup isn’t just bad for your home’s appearance. It’s affecting the air you breathe inside.
At Metro Water Blasting, we help homeowners across Hamilton fight back with professional soft house washing — the safest way to clean your exterior walls and protect your home’s health.
Here’s how an exterior clean can improve your property’s air quality, structural condition, and even resale value — especially during Hamilton’s moisture-heavy autumns and pollen-heavy springs.

Hamilton’s Hidden Problem: Organic Buildup on Exterior Walls
| Contaminant | Where It Comes From |
|---|---|
| Pollen | Trees like pine, wattle, and poplar |
| Mould spores | High humidity and shaded areas |
| Algae and lichen | Wet walls, especially near gardens |
| Dust and road grime | From nearby streets and open paddocks |
These contaminants settle and stick to your weatherboards, plaster, or brick. And once they’re on the walls, they often make their way inside via windows, vents, or gaps in the cladding.
Why Soft Washing Is Better for Hamilton Homes
Unlike high-pressure washing (which can strip paint or force water behind cladding), soft washing uses:
- ✅ Low-pressure application
- ✅ Biodegradable detergents
- ✅ A rinse-down that removes contaminants without surface damage
✅ Safe for:
- Weatherboard
- Painted or rendered surfaces
- Brick and block
- Fibre cement and cladding systems
The Link Between Dirty Exteriors and Poor Indoor Air
You clean your floors and windows to reduce dust inside… but have you cleaned the walls that sit just outside those windows?
- Mould growing on south-facing walls produces spores that travel inside
- Dust, pollen, and grime are disturbed by wind and enter through ventilation
- Damp walls can cause mildew smells that linger indoors
✅ Washing your walls keeps contaminants out — and makes a noticeable difference in how your home smells and feels.
