Your home’s exterior is constantly exposed to Wellington’s coastal winds, unpredictable weather, and salt-laden air. Over time, that exposure leads to unsightly mould, mildew, dust, and debris building up on your property. The result? A home that looks older than it is — and may even suffer long-term damage if left untreated.

That’s why regular house washing in Wellington is essential, not just for appearance, but for the health and value of your property. Whether you live in the hills of Karori, the seaside streets of Seatoun, or the heritage-lined avenues of Thorndon, Metro Water Blasting is your go-to expert for restoring your home’s curb appeal.

Why You Need House Washing in Wellington’s Climate

Wellington is beautiful — but its location and environment can be brutal on your property’s exterior. Strong southerly winds, high rainfall, and salt spray from Cook Strait can lead to:

  • Salt corrosion on coastal homes
  • Moss and lichen growth on shaded or damp walls
  • Black mould on paintwork and cladding
  • Rapid grime buildup in wind corridors like Brooklyn and Mount Victoria

Left unchecked, these issues aren’t just cosmetic. They cause:

  • Paint and timber deterioration
  • Water damage and decay
  • Decreased property value
  • Poor air quality and health risks (especially mould spores)

That’s where Metro Water Blasting steps in. We offer tailored exterior house washing using soft wash techniques that remove contaminants gently but thoroughly — protecting your paint, cladding, and garden.

Which Suburbs in Wellington Need House Washing Most?

We’ve cleaned homes all across the Wellington region, from the CBD to Johnsonville, from Karaka Bays to Aro Valley. Based on exposure, terrain, and vegetation, here are suburbs that benefit most from regular exterior washing:

1. Seatoun, Breaker Bay & Karaka Bays

Homes here are exposed directly to sea spray, salt-laden winds, and airborne sand. These conditions accelerate corrosion and attract stubborn grime.

2. Brooklyn, Kelburn & Highbury

These elevated suburbs are known for their wind tunnels, bush cover, and damp zones — all prime territory for mould and algae growth.

3. Island Bay, Lyall Bay & Owhiro Bay

Properties in these south coast suburbs face harsh conditions, including heavy rain and strong winds, leading to persistent staining.

4. Thorndon & Mount Victoria

Classic Wellington suburbs with heritage homes. These need low-pressure soft washing to avoid damaging weatherboards and fragile cladding.

5. Johnsonville, Newlands & Paparangi

Further north, homes are surrounded by trees and bush, making them susceptible to moss and mildew buildup — especially on south-facing walls.

6. Hataitai, Roseneath & Oriental Bay

With a mix of sun and salt exposure, homes in these areas require regular washing to prevent build-up that harms both aesthetics and material longevity.

No matter your location, our house washing service in Wellington is designed for the local climate and conditions.

What’s Included in a House Wash?

Here’s what you can expect from a standard house washing job with Metro Water Blasting:

  • Exterior wall cleaning: Suitable for all cladding types (weatherboard, plaster, brick, etc.)
  • Soffits, fascias and eaves
  • Doors, window frames and sills
  • Downpipes and spouting
  • Porch and entrance areas
  • Lichen, algae, and mould removal

Optional add-ons include:

Benefits of Soft Wash vs. High Pressure Washing

You might think a high-pressure blast is best — but it can do more harm than good.

We use a soft wash system, combining eco-safe cleaning agents with low-pressure water flow to gently lift contaminants. This approach:

  • Protects your paintwork
  • Avoids water intrusion under weatherboards
  • Is safe around windows, trims, and vents
  • Prevents damage to plants and landscaping

It’s ideal for homes in Thorndon, Wadestown, and Kelburn, where older houses need extra care.

How Often Should You Wash Your House in Wellington?

We recommend:

  • Every 12–18 months for most Wellington homes
  • Every 6–12 months for coastal or shaded properties
  • Before repainting, selling, or hosting guests

High-exposure areas like Breaker Bay, Lyall Bay, and Brooklyn should be on a tighter cleaning schedule due to accelerated buildup from wind and salt.

Regular washing not only preserves your home’s appearance — it extends the life of your paint and exterior surfaces, saving you money in the long run.

Real Results: Before & After Projects

We’ve helped hundreds of Wellington homeowners achieve dramatic transformations. Here are just a few highlights:

  • A full soft wash in Karori removed 2+ years of grime and mould, restoring the weatherboards to a bright, fresh white.
  • In Island Bay, we safely removed marine residue and salt buildup from a beachside villa — improving not only the look but protecting timber cladding.
  • A modern townhouse in Hataitai got a full wash + gutter cleaning package that drastically improved its street appeal before going on the market.
