House Washing in Christchurch – Protect Your Home’s Exterior from Moss, Mould, and Weathering
Christchurch homeowners know that keeping a property looking fresh and healthy isn’t easy. Between cool, damp winters and the coastal influences rolling across Canterbury Plains, your home’s exterior is constantly exposed to the elements.
Moss, mould, dirt, and lichen are common problems — and if left untreated, they can damage paint, rot timber, and even affect the health of your household.
At Metro Water Blasting Christchurch, we specialise in professional house washing services using soft wash techniques that are safe for weatherboards, plaster, Colorsteel, and other delicate surfaces. Whether you’re based in Riccarton, Cashmere, Rolleston, or Papanui, our team is ready to help protect and revitalise your home.
Why House Washing Is Essential for Christchurch Homes
Christchurch’s environment creates unique challenges for home maintenance:
- Moisture from frequent rain leads to moss, mildew, and mould growth.
- Wind-blown dust from nearby developments or farmland settles on surfaces.
- Coastal air exposure (especially in suburbs like New Brighton and Sumner) encourages salt buildup.
- Shade from large trees in older suburbs (like St Albans and Fendalton) increases algae and black mould.
Ignoring these issues can lead to costly repairs, early repainting, and permanent cladding damage.
Regular house washing prevents deterioration, protects property value, and keeps your home looking its best.
What Surfaces We Clean
Our soft wash house cleaning service is ideal for a variety of exterior materials, including:
- Painted timber weatherboards
- Plaster and monolithic cladding
- Colorsteel and corrugated iron
- Brick veneer exteriors
- Fibre cement and Hardie board
- Soffits, fascia boards, downpipes, and garage doors
No matter the style of your Christchurch property — villa, bungalow, townhouse, or modern build — we tailor the cleaning method to your surface.
Why We Use Soft Washing (Not High Pressure)
High-pressure water blasting can strip paint, crack plaster, and damage modern building wraps.
Instead, we use a low-pressure soft wash system that combines eco-friendly detergents with gentle rinsing:
- Kills moss, mould, and lichen at the source
- Lifts dirt and grime without surface damage
- Preserves paint finishes and cladding integrity
- Safe around gardens, pets, and landscaping
This method delivers long-lasting, professional results without the risks associated with high-pressure systems.

How Often Should You Wash Your House in Christchurch?
| Location / Condition | Frequency Recommendation |

| Tree-covered suburbs (Cashmere, Fendalton) | Every 6–9 months |

Regular washing prevents buildup, extends paint life, and helps maintain warranties on exterior coatings.

Real Client Story: A Rolleston Revival
A homeowner in Rolleston contacted us after noticing green mould streaking their freshly painted weatherboards just two years post-renovation. They feared premature repainting was needed.
