Rotorua's geothermal environment and moderate rainfall promotes algae and mould on exterior surfaces. Some geothermal areas have mineral deposits on surfaces that require specialist cleaning approaches.
Soft Wash vs Pressure Wash
Soft wash (low pressure + chemical treatment): Preferred for most NZ homes. A biocide kills mould, algae, and lichen at the root — prevents quick regrowth. Safe on weatherboards, painted surfaces, and roofs. Results last 2–4 years.
High pressure wash: Good for concrete driveways, paths, decks. Too aggressive for most painted or clad surfaces — can force water behind cladding or strip paint. Not recommended for roof washing.
Which to use: Soft wash for the house exterior and roof. High pressure for concrete and hard surfaces.
How Often Should You Wash Your House in Rotorua?
Rotorua's geothermal environment and moderate rainfall promotes algae and mould on exterior surfaces. Some geothermal areas have mineral deposits on surfaces that require specialist cleaning approaches. For most Rotorua homes: every 2–3 years minimum. Annual washing recommended if you have a lot of shading (overhanging trees) or if south-facing walls are affected by persistent mould.
Pre-paint: Always wash before repainting — paint won't adhere properly to mould or dirt.
