Key takeaways
- Most pressure washing jobs in New Zealand land between NZ$100–NZ$1,200 — known locally as water blasting (pressure cleaning).
- Water blasting is unlicensed in New Zealand, but council stormwater bylaws prohibit discharging detergents into street drains, and working-at-height rules under the Health and Safety at Work Act apply to roof and two-storey washes — established firms use harnesses or scaffolds rather than ladders alone.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in New Zealand typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a pressure washing pro in New Zealand
- Get 2-3 quotes from local water blasting firms or via Builderscrack/local platforms
- Verify public liability insurance before anyone climbs on your roof or scaffolds
- Ask about soft washing for weatherboard, plaster cladding, and roofs — full pressure damages paint and can void cladding warranties
- House washing is a routine annual job in NZ's damp climate — ask for a house wash + gutter clean bundle price
- Confirm runoff handling; councils prohibit detergent wash water entering stormwater drains that feed streams
- Check recent local reviews and before/after photos on similar cladding
Red flags
- High-pressure blasting proposed for painted weatherboard or monolithic cladding
- No liability insurance
- No mention of moss/mould treatment in a country where regrowth is fast
- Sight-unseen flat quotes
- Pressure on you to skip the written quote

Frequently asked questions
Is pressure washing safe for roofs?
High-pressure washing damages most roof coverings — it strips granules from asphalt shingles, cracks and dislodges tiles, and can force water under the covering. Roof cleaning should be done by soft washing or manual moss removal plus a biocide treatment. If a company proposes blasting your roof at full pressure, choose someone else.
How long does pressure washing take?
A single driveway or small patio takes 1-3 hours. A full house exterior typically takes half a day to a full day depending on size, number of storeys, and how much pre-treatment the surfaces need. Add drying time of a few hours before you walk on sealed or treated surfaces.
What surfaces can be pressure washed?
Safe at high pressure: concrete, block paving, natural stone (with care), brick in good condition, metal fences and gutter exteriors. Needs low pressure or soft washing: painted surfaces, render, timber decking, vinyl or fibre-cement siding, roofs, and old or repointed brickwork. Never pressure wash: single-glazed windows at close range, electrical fittings, or asbestos-containing materials.
What's the difference between pressure washing and soft washing?
Pressure washing uses high-pressure water and suits hard surfaces: concrete, pavers, brick. Soft washing uses low pressure plus a cleaning solution and is the right method for painted render, siding, roofs, and timber, where high pressure would strip paint, gouge wood, or crack tiles. A good pro will recommend soft washing for delicate surfaces without being asked.
Do pressure washers need my water and electricity?
Most residential pros use your outdoor tap and, for electric machines, an outdoor socket. Petrol-powered machines only need water. Some companies carry water tanks for properties without an accessible tap — ask in advance, as tank supply can add to the price. Water usage for a typical driveway job is modest, roughly comparable to a few loads of laundry per hour of cleaning.
Why is annual house washing standard in New Zealand?
NZ's damp, temperate climate grows mould, lichen, and algae on cladding fast, and many paint and cladding warranties require an annual wash to stay valid. A yearly soft wash is cheaper than repainting years early, which is why house washing is a bigger routine market in NZ than in most countries.
How much does a house wash cost in New Zealand?
A single-storey 3-bedroom house wash typically runs $250-$450, two-storey homes $400-$700. Driveways add roughly $120-$400 depending on size. Auckland and Wellington sit at the top of the range.
