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 Dunedin
Drawn from 124 customer reviews collected for this page. The first answer is what it costs.
What does house washing typically cost in New Zealand? expand_more
House washing in New Zealand runs from $150 to $500 for an average-sized home, with larger or heavily affected properties pushing higher. Soft washing a full exterior, including walls and roof treatment, can reach $600 to $700 when bundled with driveway or gutter work.
Pricing at roughly $1 to $3 per square metre is common among operators who quote that way. Getting two or three written quotes before committing is the most reliable way to benchmark what is fair for your property size and condition.
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 set up and operate without formal qualifications or registration. No Licensed Building Practitioner status is required, and the Building Act 2004 does not classify exterior washing as restricted building work.
Because there is no central register to check, ask any operator directly for proof of current public liability insurance, ideally cover of at least $1 million to $2 million, before work begins. If a washer damages your cladding, gutters, or garden and carries no insurance, recovering costs becomes your problem.
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, often sodium hypochlorite-based, to kill and lift biological growth like mould, lichen, and algae from painted surfaces. Pressure washing uses high-pressure water alone and is suited to hard surfaces like concrete driveways and brick paths, not painted weatherboards or monolithic cladding.
New Zealand's damp climate makes biological growth on cladding a recurring problem, and forcing high-pressure water near joins or window flashings on monolithic systems raises real leaky building risk. One reviewer specifically praised an operator for using soft wash on aged decking that came up without damage, which is a practical signal of method matching material.
What are the warning signs of a house washing company you shouldn't use? expand_more
- –A quote provided without a physical site visit or review of your specific cladding type is a red flag, as one negative review details a price that jumped from an initial estimate to over $1,000 after the operator finally assessed the property.
- –Watch for operators who add fees after quoting, such as a separate site assessment charge for a short trip, which one reviewer encountered on top of an already-inflated revised price.
- –Dismissive responses when you raise pricing concerns suggest the operator prioritises locking you into a timeline over honest dealing.
- –Poor or dishonest communication about delays, such as blaming access issues when the real reason was understaffing, signals an operator who will not be straight with you if something goes wrong on the job.
- –No mention of insurance or method when asked directly is a practical warning to walk away before work begins.
- –Operators who cannot explain which wash method suits your surface type likely lack the experience to avoid damaging painted or fibre cement cladding.
What should you ask before booking a house wash? expand_more
- –Ask whether they use soft wash or pressure wash and why that method suits your specific cladding, particularly if you have timber weatherboards, fibre cement, or monolithic stucco.
- –Ask what cleaning products they use for moss and mould treatment and whether chemical disposal complies with your local council's stormwater bylaws, as many councils prohibit biocide runoff entering drains.
- –Confirm whether spouting, decks, and window frames are included in the quoted price or charged separately, since bundled jobs can look cheaper until extras appear on the invoice.
- –Ask how long the result is expected to last and whether a follow-up treatment or retreatment is recommended, particularly for roofs with heavy lichen or shaded north-facing walls.
- –Request proof of current public liability insurance before agreeing to anything, since house washing is unregulated and there is no register to check independently.
- –Ask if they will provide before-and-after photos of the completed work, a practice several well-reviewed operators offer as standard.

How are the top house washing companies in Dunedin chosen? expand_more
We build this page from Google Maps results for house washing companies in Dunedin. Each one is scored on its public rating and review record. Businesses outside the area, or whose reviews describe a different line of work, are left out, and a business whose main Google category is a different trade is held back until a person has checked what it does. A business whose website no longer resolves and that has had no Google review for six months is treated as dormant and left off the page until either changes. Every category and city is rechecked on a rolling cycle, about every two to three months. A location with a subscribing business is rechecked every month, and the whole page updates with it. See how we rank for the full method.

Why isn't my business listed? expand_more
We build this page from Google Maps results for house washing companies in Dunedin. The usual reasons for missing out are a Google Business category that does not match, too few reviews to score near the top, or an address outside the area we cover. Sometimes we miss a business that should be here. Check where you rank first. If you are not there and think you should be, get in touch.
