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 Wellington
Drawn from 154 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 properties, or those with heavy moss, lichen, or mould, will sit toward the upper end or beyond.
Pricing is often calculated at $1 to $3 per square metre, so knowing your exterior surface area helps you benchmark quotes. Add-ons like roof treatment, gutter clearing, or driveway washing will increase the total, so confirm exactly what is included before comparing prices.
Does a house washing company need any qualifications or insurance to operate in New Zealand? expand_more
House washing is an unregulated trade in New Zealand, meaning there is no licence or formal qualification required to operate a business. What does matter is public liability insurance, and reputable operators carry at least $1 million to $2 million in cover.
This protection is what stands between you and an out-of-pocket repair bill if a downpipe is cracked, paint is stripped, or a ladder causes property damage. Reviews here show those scenarios do happen, so ask any operator for proof of current insurance before you confirm a booking.
What's the difference between soft washing and pressure washing, and which is right for my house? expand_more
Soft washing combines low-pressure water with chemical treatments, usually sodium hypochlorite-based, to kill and lift biological growth like mould, lichen, and algae from the surface. Pressure washing uses high-pressure water alone and is suited to hard surfaces such as concrete driveways, brick, and paths.
Most New Zealand homes have cladding types, including timber weatherboards, fibre cement, and monolithic stucco, that can be damaged by high-pressure water, with paint stripped or moisture forced behind joins. One reviewer here noted streaking on a black-painted surface, which points to product or pressure mismatch, so ask your operator specifically which method they use on your cladding type before work starts.
What are the warning signs of a house washing company you shouldn't use? expand_more
- –A company that cannot supply proof of public liability insurance before starting work is a significant risk, as damage to cladding, gutters, or roofing is a real possibility.
- –Streaking or watermarks left on the exterior after the job is done, with no offer to return and rectify, signals poor technique or the wrong product for your surface.
- –Broken or damaged spouting, cracked roof tiles, or scraped paintwork that the operator dismisses or blames on pre-existing conditions is a red flag for accountability.
- –Operators who take weeks to respond to complaints after the job, or stop communicating entirely once payment is received, should be avoided.
- –Equipment failures, staff walking off mid-job, or an operator managing jobs remotely without reliable on-site supervision are signs of a business that cannot deliver consistent results.
- –Incomplete work, such as gutters still full of weeds after a paid gutter clean, with no follow-through despite repeated requests, indicates the operator is not honouring what was quoted.
What should you ask before booking a house wash? expand_more
- –Ask whether they use soft washing or pressure washing, and confirm which method is appropriate for your specific cladding material.
- –Find out what cleaning products they use for moss and mould, and whether those chemicals comply with your local council's stormwater discharge rules.
- –Get the quote in writing and confirm exactly which surfaces are included, exterior walls, roof, gutters, downpipes, decks, and paths, so there are no disputes about scope on the day.
- –Ask whether moss and lichen treatment is a one-off rinse or a biocide application that continues to work over weeks, since the latter gives longer-lasting results.
- –Check whether they will provide before-and-after photos, particularly for roofs and gutters you cannot easily inspect yourself, as several reviewers valued this as proof of completed work.
- –Ask what happens if the result is not satisfactory, and confirm they have a clear process for returning to fix issues before you hand over payment.

How are the top house washing companies in Wellington chosen? expand_more
We build this page from Google Maps results for house washing companies in Wellington. 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.
