Before you hire

House washing methods differ: soft washing uses low pressure and cleaning agents, while high-pressure washing can damage paint and timber if used incorrectly. Ask which method they use on your cladding type, and confirm they carry insurance for paint or surface damage.

Before you book a house washing company in Hamilton

Drawn from 170 customer reviews collected for this page. The first answer is what it costs.

What does house washing typically cost in New Zealand? expand_more

A standard house wash in New Zealand runs between $150 and $500 for an average-sized home. Larger homes, or those with heavy moss and lichen buildup, will sit closer to $500 or above. Some operators price by the square metre at roughly $1 to $3 per square metre, so a bigger footprint adds up quickly. Bundled packages that include roof treatment, gutter cleaning, and driveway washing can push the total well past $500, so clarify exactly what is included before you accept a quote.

Does a house washing company need any qualifications or insurance to operate in New Zealand? expand_more

House washing is not a licensed trade in New Zealand, so anyone can legally operate a business without formal qualifications or registration. That makes insurance the most important thing to verify before booking, as reputable operators carry public liability cover of at least $1 million to $2 million to protect you if cladding, gutters, or fixtures are damaged during the job. Review evidence backs this up as a real risk: in one case an operator broke guttering and damaged outdoor furniture, and in another a water ingress incident caused electrical damage to an outdoor sensor. Ask for written proof of current public liability insurance before work begins, because there is no central register where you can verify this independently.

What's the difference between soft washing and pressure washing, and which is right for my house? expand_more

Soft washing uses low-pressure water combined with chemical treatments, usually sodium hypochlorite-based, to kill and lift biological growth like mould, lichen, and algae from cladding surfaces. Pressure washing uses high-pressure water without chemicals and is suited to hard surfaces like concrete driveways, paths, and brick. Most New Zealand homes clad in timber weatherboards, fibre cement, or monolithic stucco should be soft washed, because high pressure near window flashings or joins increases leaky building risk and can lift paint or roughen timber surfaces, which one reviewer experienced firsthand after a pressure wash left their deck wood rough and requiring sanding.

What are the warning signs of a house washing company you shouldn't use? expand_more
  • –Operator cannot confirm in advance which method they will use on your specific cladding type, soft wash or pressure wash.
  • –Charging for a job they attempted but could not complete, rather than absorbing the cost of their own misjudgement.
  • –Roof treatment that shows no visible improvement after the agreed timeframe, with no follow-up offered beyond a token refund.
  • –Bleach or chemical solution entering the home through door gaps or window seals, causing damage to interior floors or joinery.
  • –Outdoor furniture, hoses, or guttering left damaged or displaced after the job with no acknowledgement from the operator.
  • –Operator becomes defensive or dismissive when you raise concerns, rather than returning to inspect and rectify the issue.
What should you ask before booking a house wash? expand_more
  • –Ask whether they use soft wash or pressure wash and confirm which method is appropriate for your specific cladding material.
  • –Ask what chemical products they use for moss and mould treatment, and how they dispose of runoff, as many councils prohibit biocide entering stormwater drains.
  • –Confirm whether gutters, downpipes, decks, and driveways are included in the quoted price or priced separately.
  • –Ask how long the roof or moss treatment takes to show results, and what warranty or return visit is included if it does not work.
  • –Request before and after photos, several operators across these reviews offered this as standard practice and it gives you clear evidence of what was done.
  • –Ask whether they carry public liability insurance and request written confirmation before work begins.
