For most homes, every 12 to 24 months is a sensible starting point. Properties surrounded by trees, close to the coast or sitting in damp, shaded areas can show mould and green growth sooner. We normally recommend cleaning based on what the exterior actually needs rather than washing it unnecessarily.

For house exteriors we generally use a controlled soft-washing approach. It allows us to deal with dirt, mould and exterior growth without relying on aggressive pressure against paintwork and cladding. Hard surfaces can be treated differently where appropriate. Soft washing is now widely promoted by Auckland exterior-cleaning companies specifically for painted and more delicate exterior surfaces.
