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 Nelson
Drawn from 235 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 buildup, will sit toward the higher end or beyond it.
Pricing in smaller regional centres like Nelson can differ from Auckland or Wellington, so getting two or three written quotes is the most reliable way to benchmark local rates. Add-ons like roof treatment, driveway washing, and gutter clearing will increase the total, but some operators bundle these in at a better combined rate than booking them separately.
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. The critical protection to check is public liability insurance: a reputable operator should carry at least $1 million to $2 million in cover, which protects you if cladding, windows, or landscaping are damaged during the job.
There is no central register to verify this independently, so ask the operator directly for proof of current cover before work begins. Reviews from Nelson operators show that some property owners left crews to work unsupervised, which makes confirmed insurance coverage even more important before you hand over access.
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 a cleaning solution, usually sodium hypochlorite-based, to kill and remove biological growth like mould, lichen, and algae at the source. Pressure washing relies on high-pressure water alone and works well on hard surfaces like concrete driveways and paths, but it can damage paint systems, force water behind flashings, or compromise the integrity of cladding types like fibre cement, timber weatherboards, and monolithic stucco. One Nelson reviewer specifically noted that a heritage home required a gentle wash to protect thin, fragile glass, which illustrates how the wrong method can create real risk on older or more delicate properties.
What are the warning signs of a house washing company you shouldn't use? expand_more
- –Failing to show up for a scheduled quote appointment with no call or explanation is a strong indicator of unreliable operations.
- –Inability to remove established mould or biological staining, leaving problem areas untreated, suggests the operator lacked the right method or product for the job.
- –Leaving site without restoring water connections, irrigation taps, or other utilities to their original state shows poor site discipline.
- –Damage to surfaces with no clear process for resolving the issue, or minimal effort to help rectify their mistake, signals that the operator does not carry adequate accountability.
- –No photographic record or follow-up communication after the job makes it harder to raise a complaint if problems appear later.
- –Quoting and booking without asking about your cladding type or existing surface condition suggests the operator is applying a one-size-fits-all approach.
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 type before agreeing to anything.
- –Ask what chemical products they use for moss and mould treatment, and whether those products comply with your local council's stormwater bylaws on biocide runoff.
- –Confirm exactly what is included in the quoted price: whether spouting, decks, driveways, window exteriors, and roof treatment are covered or priced separately.
- –Ask whether they carry current public liability insurance and request proof before work begins.
- –Ask how long results are expected to last and whether a post-treatment or follow-up application is recommended to prevent regrowth.
