House Washing New Zealand

Frequently Asked Questions

Everything you need to know about professional house washing, answered honestly.

House washing is the professional cleaning of your home's exterior surfaces removing dirt, mould, mildew, algae, and grime that build up over time. In New Zealand's varied climate — from humid northern regions to wet western coasts and cold southern winters — these contaminants accumulate faster than most homeowners expect. Regular house washing protects your siding from long-term damage, maintains your home's value, and keeps it looking its best year-round.
While DIY options exist, they rarely deliver the same results and can cause costly damage if the wrong pressure or chemicals are used on your siding. A professional service has the right equipment, proven techniques, and experience with New Zealand homes specifically. It's a worthwhile investment to get the job done safely and thoroughly the first time.
For most homes across New Zealand, we recommend a professional wash at least once a year. However, properties near the coast, in bush settings, or in shaded areas with poor airflow often need cleaning every six months due to faster mould and algae growth. If you notice green or black staining starting to appear, it's time to book a wash.
Soft washing uses low pressure combined with specialist cleaning solutions to safely remove contaminants from your home's exterior. It's the preferred method for most residential surfaces — particularly weatherboard, painted timber, and older claddings — where high-pressure washing could cause damage. We assess your home's specific materials before recommending the right approach.
Yes, when done correctly. Most common cladding types including vinyl, brick, stucco, timber, and fibre cement can be safely cleaned by an experienced professional. The key is using the right pressure and solutions for each material. We tailor our method to suit your home, so there's no risk of unnecessary wear or damage.
Pricing depends on the size of your home, the type of cladding, and the level of contamination. Most New Zealand residential properties fall within a reasonable range, and we provide transparent, obligation-free quotes upfront — no surprises on the day. Get in touch for a free assessment and accurate price for your specific property.
We take care to protect your landscaping throughout the process — pre-wetting surrounding plants and using biodegradable, eco-friendly cleaning solutions. It's worth trimming back any delicate plants close to the house beforehand, but in most cases your garden will be completely unaffected.
Yes. Professional-grade cleaning solutions can tackle rust, oil, heavy mould, and other stubborn staining that standard garden hose washing won't touch. If your home has persistent marks or discolouration, we can assess the best treatment during your free quote.
Removing mould, mildew, cobwebs, and organic buildup from your exterior reduces conditions that attract certain insects and pests. It can also improve indoor air quality — mould spores from exterior surfaces can find their way inside through gaps and ventilation. For serious pest issues, we'd recommend also consulting a pest control specialist.
Look for a company with verified reviews, proper insurance, and technicians who take time to assess your home before quoting. Eco-conscious cleaning practices and transparent pricing are also good signs. We're happy to answer any questions before you commit — our goal is to earn your trust, not just your business.
