What Affects the Cost of House Washing?
Home size and number of storeys
Larger homes and double-storey properties take longer to clean and require additional safety equipment for upper levels. This is the biggest single factor in pricing.
Cladding type
Weatherboard, rendered brick, Hardiplank and Colorbond all have different cleaning requirements. Rendered surfaces with heavy mould staining may require a second pass or stronger treatment.
Level of mould, algae and dirt
A home that hasn't been washed in 3–5 years will have significant biological growth, particularly on south-facing walls and under eaves. Heavy buildup requires more time and product.
Driveway and path inclusion
Many customers combine a house wash with a driveway and path clean for a discounted package rate. This is often the most cost-effective option.
Access
Homes with restricted side access, steep terrain or pool fencing that limits equipment movement may incur a small access surcharge.
Soft Washing vs Pressure Washing Your House
At WSI Cleaning, we use soft washing for all house washing jobs. Soft washing uses low-pressure water and a biodegradable cleaning solution that kills mould, algae and bacteria at the source — rather than just blasting it off the surface with high pressure.
High-pressure washing can strip paint, force water behind cladding (causing internal mould), crack render and damage window seals. Soft washing is safer for your home and produces results that last 2–3x longer. Read more: Soft Wash vs Pressure Wash — Which Is Better?
