How often should I have my house washed?

Most premium homes benefit from exterior washing every 12 to 18 months. Coastal properties, heavily shaded homes, and properties in high-humidity or high-rainfall areas may benefit from annual washing. We assess your specific property and recommend the right frequency based on your cladding type, location and exposure.

What is soft washing and is it safe for my cladding?

Soft washing uses low water pressure combined with specifically formulated cleaning solutions to break down organic matter, including mould, algae, lichen and dirt, at the surface level without the mechanical force of high-pressure washing. It is generally the safest and most effective method for painted surfaces, weatherboards, timber, fibre cement, plaster and most premium cladding types. It's what we recommend for the vast majority of high-value homes.

Will house washing damage my paint or cladding?

When done correctly using appropriate pressure and the right cleaning agents, exterior washing should not damage sound paintwork or cladding. The risk of damage comes from using incorrect pressure, typically too high, or inappropriate chemicals. We assess your cladding before washing and select the method and products appropriate to your specific surfaces.

Do I need to be home during the house wash?

In most cases, no. We can complete the exterior wash without you being present, provided we have access to the property and relevant water connections. We'll confirm access requirements at the time of booking and communicate before and after the service.

What cladding types do you wash?

We wash all common New Zealand residential cladding types including painted weatherboard, fibre cement (Hardieplank and similar), vertical shiplap, cedar, plaster/render systems, brick, and metal cladding. Our method is calibrated to the specific cladding to protect the surface while achieving a thorough clean.

What's the difference between a standard clean and what Prevent does?

A standard exterior wash is about removing visible surface dirt. Our approach is preventative: we assess the whole exterior, identify biological growth at early stages, select methods that protect the surface long-term, and make note of any emerging issues on the cladding or building envelope that may warrant attention. It is a more thorough, more considered service.

Premium House Washing for High-Value Homes

Your home's exterior does more than protect the building envelope — it makes an impression. It signals the standard of care inside, and it reflects how you feel about the property you own. We wash premium homes to get them looking their absolute best: carefully, thoroughly and with full consideration for your cladding, surfaces and long-term property value.

Prevent Maintenance provides premium house washing for high-value homes across Auckland, including North Shore, Hibiscus Coast, Rodney and the eastern suburbs. We use soft washing, low-pressure application of professional-grade cleaning solutions, as the primary method for exterior cleaning on premium homes. This approach removes mould, algae, lichen and organic build-up at the surface level without the mechanical risk of high-pressure washing. The result is a cleaner, longer-lasting finish that protects your cladding and paintwork rather than compromising it.

Method Matters

Why soft washing is the right choice for premium homes

High-pressure washing is fast and visually impressive. It strips surface contamination in seconds. But for premium cladding, painted surfaces, weatherboards and plaster systems, it carries real risk. Excessive pressure can force water behind cladding, damage paint bonds, erode substrate edges and create conditions for future moisture ingress.

Soft washing uses low pressure, typically well below the threshold that could damage sound surfaces, combined with biodegradable cleaning solutions that break down biological growth chemically rather than mechanically. Mould, algae and lichen are treated at the source, not just blasted off the surface. The result lasts significantly longer, and the process is safer for your home.

For most premium homes in Auckland, soft washing is the appropriate method. There are situations where controlled water blasting is appropriate, including hard surfaces, concrete and certain stone, but for your home's exterior cladding, soft washing is almost always the better choice.

Who This Is For

For house-proud homeowners who take property care seriously

Our house washing service is for owners of premium homes, typically $2 million and above, who take pride in how their property looks. These are homeowners who notice the difference between a careful exterior wash and a quick blast — who entertain at their homes, who are proud of what they've built or bought, and who want a provider they can trust to keep that exterior looking its absolute best, every time.

We also work with property managers, body corporates, and real estate professionals who need reliable exterior maintenance on a consistent schedule. If you manage multiple properties or are preparing a premium home for sale, we can accommodate your specific requirements.

High-value homeowners

Owners of premium homes who want their exterior properly maintained, not just quickly cleaned.

Pre-sale preparation

A thoroughly washed exterior significantly enhances kerb appeal and buyer perception.

Prevent Plan members

House washing is a core element of the Prevent Plan scheduled maintenance service.

Benefits & Outcomes

What a premium house wash delivers

Preserved paintwork and cladding

Biological growth, including mould, algae and lichen, breaks down surface coatings over time. Regular washing removes these agents before they cause lasting damage to your paint or substrate.

Extended maintenance intervals

A thorough soft wash doesn't just clean. It treats the surface. Professional-grade biocidal solutions inhibit regrowth, meaning your home stays cleaner for longer between services.

Early issue identification

During the washing process, our team is well-positioned to observe cladding condition, paint failure, cracking or other emerging issues, catching problems early before they become expensive repairs.

Improved kerb appeal & presence

An immaculately maintained exterior signals the quality of ownership and care inside. The impression your home makes matters — whether you're entertaining guests, showcasing to buyers, or simply arriving home at the end of the day.

Healthier living environment

Mould and biological growth on exterior surfaces can affect indoor air quality, particularly where windows and vents are in proximity. Regular exterior washing reduces this risk.

Protected property value

Consistent exterior maintenance is one of the most cost-effective ways to protect long-term property value. Prevention is always less expensive than restoration.

The Prevent Standard

How we approach every house wash

Every house wash begins with an assessment: not just a walk-around, but a considered review of your cladding type, condition, level of biological growth and any visible areas of concern. This informs the method, products and pressure settings we use.

We protect landscaping and sensitive areas before beginning, work systematically from top to bottom, and finish with a full inspection. If we notice anything worth bringing to your attention, such as early paint failure, cladding movement or gaps in sealant, we'll tell you.

Property Assessment

We assess your cladding type, surface condition and level of biological growth to select the right method and products.

Surface Preparation

Gardens, windows and sensitive areas are protected. Water connections are confirmed and equipment set up.

Soft Wash Application

Professional-grade cleaning solution is applied to the exterior surfaces and allowed to dwell, treating biological growth at the root level.

Low-Pressure Rinse

Surfaces are rinsed at appropriate pressure, working top to bottom to ensure a clean, streak-free finish.

Final Inspection & Report

We inspect the completed work and note any observations about cladding condition or emerging issues worth bringing to your attention.

Pricing

Transparent, property-specific pricing

House washing pricing varies by property size, cladding type, level of biological growth and access requirements. We provide fixed-price quotes before any work begins with no surprises, no variations unless the scope genuinely changes.
