What is different about pressure washing in Adelaide
Adelaide pressure washing follows a Mediterranean calendar: winter rain grows moss and algae on shaded paths, pavers and south-facing walls, summer dust and pollen settle on everything, and the city’s large stock of light-coloured render, brick and limestone shows it. Limestone and sandstone, common in Adelaide’s heritage homes and walls, need particular care because high pressure and acidic cleaners damage them.
Operators range from sole traders to businesses combining washing with gutter cleaning and painting prep. Water restrictions have applied in drought years through SA Water and can limit hard-surface washing.
Winter moss
Shaded paths and walls grow moss and algae over winter; spring is the time to treat.
Limestone and sandstone
Common in older homes and walls; need low pressure and neutral cleaners.
Dust and pollen
Dry summers coat surfaces; a post-summer wash freshens light exteriors.
Restrictions
Drought-year rules can limit hard-surface washing.
