Before you hire
Whether you call it house washing, a building wash or exterior house cleaning, the 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, whether they also do roofs and windows, and confirm they carry insurance for paint or surface damage.

Before you book a house washing company in New Plymouth
Drawn from 54 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 costs between $150 and $500 for an average-sized home. Larger homes or those with heavy moss or lichen buildup will sit toward the top of that range.
Some operators price by the square metre at roughly $1 to $3 per square metre, so measuring your exterior walls before calling for quotes is useful. Bundling in roof treatment, gutter clearing, or driveway washing adds to the total, but review feedback from New Plymouth suggests bundled pricing can still represent good value.
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, meaning anyone can legally operate one without formal qualifications or registration. No Licensed Building Practitioner status is required, as the Building Act 2004 does not classify exterior washing as restricted building work.
What matters most is public liability insurance: reputable operators carry at least $1 million to $2 million in cover to protect you if cladding, glass, or landscaping is damaged during the job. Ask for proof of current insurance before booking, because there is no central register in New Zealand 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 pairs low-pressure water with chemical treatments, usually sodium hypochlorite-based solutions, to kill and remove biological growth like mould, algae, and lichen without mechanical force. Pressure washing relies on high-pressure water alone and is suited to hard surfaces like concrete driveways, brick, and paths rather than painted cladding.
Most New Zealand homes use cladding types such as James Hardie fibre cement, timber weatherboards, or monolithic stucco, all of which can have their paint systems compromised or, in the case of monolithic cladding, face increased leaky building risk if high pressure forces water near joins or flashings. One review in this market noted that bare timber decking became fuzzy after washing, which points to the importance of discussing your specific surfaces with the operator before work begins.
What are the warning signs of a house washing company you shouldn't use? expand_more
- –A quote is given without an in-person inspection of the cladding type, roof condition, or access difficulty.
- –The operator cannot explain which method they will use on each surface or why it suits your cladding.
- –Proof of public liability insurance is refused or not provided promptly when requested.
- –Previous customers report streaking, chemical residue left on windows, or areas missed at height.
- –The operator has no process for protecting garden beds, plants, or outdoor furniture before applying chemical treatments.
- –Follow-up communication after the job is non-existent, with no offer to return if an area needs attention.
What should you ask before booking a house wash? expand_more
- –Ask whether they use soft washing or pressure washing on your specific cladding, and get a clear reason for their choice.
- –Ask what chemical products they use for moss and mould treatment, and whether disposal complies with your local council stormwater bylaws.
- –Confirm in writing whether spouting, decks, driveways, and fences are included in the quoted price or priced separately.
- –Ask how long the result is expected to last and whether a follow-up moss or algae treatment is recommended after the wash dries.
- –Request proof of current public liability insurance before agreeing to any work.
- –Ask whether they will return at no charge if areas are missed or if results are unsatisfactory after the job is complete.

Why isn't my business listed? expand_more
We build this page from Google Maps results for house washing companies in New Plymouth.
