Wellington’s central suburbs are some of the oldest and most iconic in the country — filled with historic villas, heritage cottages, and tightly packed townhouses. From the leafy streets of Thorndon to the hillside homes of Mount Victoria, these areas are rich in character but vulnerable to wear and tear from wind, rain, and city grime.
Whether you’re a homeowner in Aro Valley, a landlord in Te Aro, or a body corporate in Mount Cook, your property is exposed to dust, mildew, pollution, and Wellington’s relentless southerlies. That’s why regular house washing is a must — not just for aesthetics, but for property preservation and safety.
At Metro Water Blasting, we offer specialist soft house washing services across central Wellington, tailored for homes with complex layouts, fragile paintwork, and minimal access. We know the quirks of city homes — and how to clean them safely and thoroughly.

Why House Washing Is Essential in Wellington’s Central Suburbs
Wellington Central sees a unique mix of environmental stressors:
- Airborne pollutants from traffic, building works, and urban density
- Moisture buildup in shaded valleys like Aro Valley and Mount Victoria
- Black mould and mildew on southern walls and paintwork
- Grime buildup under eaves, window trims, and downpipes
- Salt haze and dust, especially near the waterfront in Te Aro
Add in tight property spacing, dense foliage, and older materials, and you’ve got a recipe for rapid exterior deterioration if left unwashed.
Suburb-by-Suburb Breakdown: Central Wellington Challenges
✅ Thorndon
Home to Parliament and dozens of well-preserved villas. These properties are often over a century old, with delicate weatherboards and lead-based paints that require low-pressure soft washing to avoid damage.
✅ Mount Victoria
Steep terrain, shaded alleys, and sea views make this a hotspot for mould, mildew, and paint fade. Homes on hillsides also suffer from water runoff splashing dirt onto baseboards.
✅ Aro Valley
High humidity, narrow streets, and bushy backyards mean persistent green growth on cladding. South-facing homes often suffer serious algae buildup by winter’s end.
✅ Te Aro
Urban townhouses, apartments, and terrace homes often accumulate air pollution, dust, and cobwebs. Soft wash is ideal for painted concrete, brick, and newer cladding systems.
✅ Mount Cook
Mixed-use residential areas with older student flats and investment properties. Many go years without a wash — leading to deeply embedded grime.
What’s Included in Our House Washing Service
Our standard house wash includes:
- Soft wash of all exterior walls (timber, brick, plaster, etc.)
- Gutter and fascia cleaning (external only)
- Soffits, eaves, downpipes, doors and trims
- Window surrounds (frames and ledges)
- Baseboards and skirting cladding near ground level
Our biodegradable detergent lifts grime and kills mould spores, while our low-pressure rinse safely removes residue — even on historic buildings.

Real Results from Wellington Central Homes
A client in Thorndon called us to clean a double-storey heritage villa with spiderwebs, salt dust, and algae buildup on the lower floor. Our team used scaffold and soft wash to bring it back to a fresh, crisp white — without damaging its original timber cladding.
In Aro Valley, a 1970s rental home had black streaks running down all four walls, especially the shaded south side. After treatment and rinsing, the home looked years newer — and the landlord booked in a roof and gutter clean the following week.
