Exterior cleaning · Greater Sydney
Sydney exterior cleaning that actually lasts.
We soft wash rather than blast. Low pressure and biodegradable chemistry kill mould and algae at the root, so your roof, walls and driveway stay clean four to six times longer — with nothing stripped, cracked or damaged along the way.

Guides
Straight answers, no sales pitch.
What things cost, how often they're needed, and which method is right for which surface — written for Sydney conditions.
Method
What is the difference between soft washing and pressure washing?
Soft washing uses low pressure — about 150 to 180 PSI — plus biodegradable detergents that kill mould and algae at the root. Pressure washing uses high-pressure water alone, usually above 2,000 PSI, to blast contaminants off. Soft washing suits walls, roofs and painted surfaces; pressure washing suits concrete and pavers.

Maintenance
How often should you clean your house exterior in Sydney?
Most Sydney homes need a house wash every 12 to 18 months, gutters cleared annually, windows cleaned every 3 to 6 months, solar panels cleaned every 6 to 12 months and the roof cleaned every 18 to 24 months. Coastal, shaded and heavily treed properties need the shorter interval in each range.

Pricing
How much does roof cleaning cost in Sydney?
Roof cleaning in Sydney typically costs between $450 and $1,200 for a standard residential home. Price is driven by roof area, pitch, storey height, access and how much lichen and moss has established. Bundling gutter cleaning with roof cleaning usually reduces the combined price.
