Benefits of
House Washing

House washing offers several advantages, both aesthetically and functionally. Here are some key benefits:

  • Enhanced Curb Appeal: House washing removes dirt, stains, and grime, revitalising the appearance of your home. This can improve curb appeal, making your property look well-maintained and inviting.
  • Healthier Living Environment: Removing mould, mildew, and allergens from your home’s exterior can contribute to a healthier living environment. This is especially important for individuals with respiratory issues.
  • Increases Property Value: A clean and well-maintained exterior positively influences the perceived value of your property. If you’re considering selling, house washing can contribute to a higher resale value.
  • Prolongs the Lifespan of Surfaces: Regular cleaning helps extend the lifespan of exterior surfaces such as siding, paint, and roofing materials. By preventing the accumulation of damaging substances, you reduce the need for premature repairs or replacements.
  • Protects Against Damage: Cleaning away contaminants such as algae, moss, and bird droppings can prevent long-term damage to your home’s exterior. These substances, if left untreated, can degrade surfaces over time.

Soft on Cedar
Tough on Mould

The true test of a house washing professional is how well he or she can wash Cedar! Cedar is a soft wood which can be easily damaged by high pressure or stiff brushing. Stains and oils can quickly oxidise on this building material, making it even more tricky to wash.

At HWNZ we truly understand the word ‘soft’ and what it means to our customers and the integrity of their homes.

Without regular maintenance, Cedar can become discoloured and damaged. Washing cedar cladding is a simple yet effective way to protect your investment and keep it looking its best for years to come.

surfaces for paint

Painters require the cleanest of surfaces to ensure their new paint adheres properly.

Pre-paint washing involves removing dirt, grime, mildew, and other contaminants from the surface of the home,
If a house is not washed properly before painting, the new paint may not adhere to the surface, resulting in peeling, cracking, or flaking of the paint, requiring a complete redo of the painting job.

Additionally, pre-paint washing can also reveal any areas of the house that require repairs or attention, such as damaged weather boards / facia boards. Addressing these issues before painting can prevent further damage and ensure that the new paint job looks its best.

The Soft Washing

Steps we follow:

  1. The biodegradable detergent is applied to the external surfaces of the house at a low pressure.
  2. The detergent is left for about 10 minutes to neutralise mould and algae and to detach them from the surface. After this time the mould and algae is washed off at a low pressure.
  3. All external windows are brush washed with a pure water system.
  4. We re-check all of our work to make sure it is of the highest quality.


Professional house washing services enhance your house’s curb appeal and contribute to its longevity. Regular cleaning helps prevent mould, mildew, and other contaminants, ensuring a healthier living environment.

The frequency of house washing depends on factors like your location, climate, and the surrounding environment.

We prioritise eco-friendly practices, using biodegradable and non-toxic cleaning solutions. Our methods are designed to effectively remove dirt and grime while being gentle on the environment.

House washing suits various surfaces, including vinyl siding, brick, stucco, and wood. Professional services tailor the approach based on the specific material of your house.

While DIY house washing is possible, it’s recommended to hire professionals. They have the right equipment, expertise, and cleaning solutions to ensure a thorough and safe cleaning process without damaging your property.

Absolutely! We take precautions to protect your plants and landscaping during the washing process. Our team uses environmentally friendly solutions that won’t harm your greenery.

While you don’t need to be at the house, we recommend it for your peace of mind. If you cannot be present, we can arrange access and ensure a secure and thorough cleaning process.

The duration varies depending on the size of your house and the extent of cleaning required. Generally, a standard house washing can be completed within a day.
