In Brisbane’s subtropical climate, most homes should be washed once a year. Homes in shaded areas, near trees, or in high-humidity pockets may need washing every 6 months due to accelerated mould and algae growth. Properties exposed to full sunlight can sometimes go 18 months between washes. The best indicator is visible mould, dark streaking, or discolouration on exterior walls.

Soft washing uses low-pressure water combined with a biodegradable cleaning solution to safely remove mould, algae, lichen, and grime from painted walls, render, weatherboard, and timber surfaces. Pressure washing uses high-pressure water and is suited to hard surfaces like concrete driveways and paths. High pressure should never be applied directly to house walls as it can strip paint, damage timber, and force water into areas that cause long-term damage.

Professional soft wash house washing will not damage paint. In fact, regular washing extends the life of your exterior paint by removing mould spores, which are the leading cause of paint failure. Damage occurs when untrained operators use high pressure directly on painted surfaces. A professional service uses the correct pressure and cleaning solution for each surface type.

A full external house wash typically covers the exterior of gutters, eaves, soffits, all external walls, railings, balustrades, balconies, and windows. Some services also include a mould treatment that prevents regrowth for up to 12 months. Driveways, roofs, and fences are usually quoted separately as additional services.

External house washing in Brisbane typically costs between $250 and $600 for a standard residential property, depending on the size of the home, the level of soiling, and whether additional services like roof cleaning or driveway washing are included.

External house washing covers all painted and unpainted exterior surfaces including brick, render, weatherboard, timber, Colorbond, fibrous cement sheeting, and glass. The cleaning method is adjusted based on the surface material. Hard surfaces like concrete and pavers are pressure cleaned, while delicate surfaces like painted walls and timber receive a soft wash treatment.
