Wellington’s Western Hills offer stunning views, bush-clad surroundings, and a peaceful lifestyle — but these same features create the perfect environment for moss, mould, and grime to thrive on your home’s exterior. Whether you live in Karori, Wilton, Northland, Highland Park, or Kelburn, homes in these areas are exposed to shade, moisture, and tree debris year-round.
Metro Water Blasting offers professional soft house washing across all of Wellington’s Western Hills, with eco-safe treatments and gentle low-pressure cleaning methods that remove dirt without damaging your paint or cladding. Whether you own a modern home, a heritage villa, or a multi-level hillside property, we tailor the clean to your suburb, surface, and situation.

Why Western Hills Homes Need More Frequent House Washing
The Western Hills are uniquely challenging for homeowners:
- Dense native bush increases mould, algae, and moss
- Heavy rainfall leads to surface staining and moisture buildup
- Shaded valleys and ridgelines mean less sun to dry off walls
- Steep topography makes traditional cleaning more difficult
- Leaf debris and pollen from trees like rimu, pine, and tōtara build up on walls and eaves
Whether it’s a weatherboard home in Karori, a concrete-rendered house in Wilton, or a modern townhouse in Northland, regular soft washing is the only safe and long-term solution to preserve your home’s appearance and integrity.
Key Suburbs We Serve in the Western Hills
✅ Karori
As one of Wellington’s largest suburbs and surrounded by bush, Karori homes often face north-facing weathering and heavy leaf buildup. Moss grows on southern walls, while shaded areas collect black algae and cobwebs. Soft washing here is essential.
✅ Wilton
This hilly, bush-filled suburb is known for high humidity and tree-lined properties. Exterior walls, decks, and even concrete stairs get slippery — our service removes bio-growth and reveals the clean lines of your cladding without harming it.
✅ Northland & Highland Park
Close to central Wellington yet surrounded by hills, these areas combine city soot with valley dampness. Homes here often need cleaning to address dirt buildup on both the upper facades and ground-level trims.
✅ Kelburn
With its combination of heritage villas and modern hillside homes, Kelburn presents different cleaning challenges. Wooden weatherboards, stucco, and high balconies all benefit from professional low-pressure house washing.

What’s Included in Our House Washing Service?
Our soft wash covers all visible exterior surfaces, including:
- Weatherboards, painted brick, render, and modern cladding
- Eaves, fascia boards, soffits, and gutter exteriors
- Window trims, sills, entry doors, and garage fronts
- Front steps, porch ceilings, baseboards, and foundation lines
We use biodegradable detergents and a low-pressure rinse that won’t strip paint or force water behind your cladding. This ensures:
- Safe removal of moss, mould, algae, dust, soot, and cobwebs
- Protection of paintwork on villas and timber cladding
- No risk to old or fragile finishes in historic zones like Kelburn and Northland
Local Examples: House Washing in the Hills
✅ Karori Bungalow Refresh – A timber-clad home surrounded by native trees was darkened by moss and grime. After pre-treatment and a full soft wash, it looked freshly painted.
✅ Northland Townhouse Clean – Modern cladding panels near a busy intersection had traffic film and spiderweb buildup. Our team restored a clean, streak-free finish using soft wash and detail work.
✅ Wilton Weatherboard Restore – Elevated bush surrounds had caused green slime buildup. The house was safely cleaned with no paint loss or runoff issues, restoring kerb appeal.
Why Homeowners Choose Soft Wash Over Water Blasting
Traditional water blasting might seem like a solution, but for most Wellington homes — especially those in the Western Hills — it does more harm than good. Here’s why soft washing is superior:
| Feature | Soft Washing | Water Blasting |
|---|---|---|
| Surface Safety | Low-pressure, safe on all claddings | Risk of paint stripping, damage |
| Reach & Coverage | Long-reach tools, no ladders needed | Limited reach on multilevel homes |
| Algae & Mould Removal | Kills growth at the root | Only removes surface layer |
| Window & Trim Safety | No leaks into framing | Water can force behind seals |
| Eco-Safe | Uses safe, biodegradable solutions | May require harsh chemicals |
Add-On Services for Full Exterior Restoration

- Roof Moss Treatment – Especially for shaded tile or iron roofs in bush zones
- Gutter Cleaning – Prevent blockages from pine needles and leaf matter
