The Benefits of a House Wash

House wash Auckland removes mould, mildew, moss and dirt from the exterior surfaces of homes using low to moderate water pressure combined with algaecides and detergents. It also includes cleaning all window frames and doors.

Depending on the surface material (Hardie siding, brick, Stucco or vinyl) determines the algaecide detergent strength and mixture ratio. The dwell time must be adhered to.


A clean house gives a good first impression to any potential buyers of your home, and it also extends the life of your paint, bricks or weatherboards. A professional House wash Auckland will remove dirt, grime and mould, and leave you with a sparkling clean property. It’s important to choose the right professionals to do your cleaning to avoid expensive damage such as “pencil stripping”, flash oxidation and chalky residue on doors and windows.

The correct chemical and pressure used on the surface determines how well a House wash will go. Typically the House washing solution is a 1% to 3% mix ratio of sodium hypochlorite (SH) to water. It is sprayed or brushed onto the exterior surfaces, and dwell times are adhered to.

A standard House wash includes removing cobwebs, cleaning all guttering and down pipes, eaves, barge boards, gable ends, flashings, all cladding, and external window frames. Then rinsing the whole exterior of the house using a low pressure white chemical nozzle.


A standard house wash involves removing cobwebs, washing the outside edges of guttering, barge boards, gable ends, flashings, all cladding and windows (using low chemical pressure) and the outside of doors. The house washing chemicals are mixed with water at a ratio of between 1% and 3% sodium hypochlorite and are applied using special soft house wash chemical nozzles. The chemical is allowed to dwell on the surface for between 1 and 3 minutes before rinsing off with water at low pressure to avoid streaking.

Regular washing of cladding and paint surfaces with the proper cleaning equipment can extend their life, protect the environment and create a better first impression on guests. House washing Auckland professionals follow strict work practices to avoid damage from over-use of high pressure water, harsh chemicals and unsuitable work methods.

The exterior of your house is exposed to the elements all year round which cause wear-and-tear. The sun’s harsh rays fade paintwork and discolour surfaces, the rain can erode and crack surfaces, and the wind can carry dirt and debris. Regular washing can help protect these surfaces and prevent damage over time.

Washing the outside of your home also removes allergens like pollen, spores and mildew which can affect indoor air quality. This creates a healthier living environment for your family and can reduce the amount of time spent coughing, sneezing or with watery eyes.

Regular washing will protect the cladding and paint surface of your house and can prolong its life. It can also help to prevent rot, mould and mildew growth which can be costly to remove and repair. A well-maintained property will also retain its value for resale. This is especially true for properties that are rented out. A well-maintained property is more appealing to potential tenants and can make a great first impression.
