“How much does house washing cost?”
The price of house washing can vary depending on several factors such as the size of the property, accessibility, and the level of dirt or mould buildup.
Understanding how pricing works helps homeowners know what to expect and why professional house washing is a worthwhile investment.

What Affects the Cost of House Washing?
Several factors influence the price of house washing.
Size of the Property
Larger homes require more time, equipment, and cleaning solution. This is usually the biggest factor affecting price.
Height of the House
Two-storey homes require additional equipment and safety precautions. This can increase the cost compared to single-level homes.
Level of Dirt and Mould
Homes with heavy mould or algae buildup require additional treatment and cleaning time.
Soft washing solutions are often used to break down organic growth safely.
Accessibility
If parts of the house are difficult to access, additional setup may be required. Properties with steep sections or obstacles can increase labour time.
Additional Exterior Cleaning Services
Many homeowners combine house washing with other services such as:
- Roof cleaning
- Gutter cleaning
- Concrete cleaning
- Deck cleaning
Bundling services often improves overall property appearance.
Why Soft Washing Is Used for House Cleaning
Professional house washing usually involves soft washing, which uses low-pressure water and specialised cleaning solutions.
Soft washing safely removes:
- Mould
- Algae
- Dirt
- Cobwebs
- Pollution buildup
This method protects painted surfaces and cladding from damage.
Benefits of Professional House Washing
Regular house washing provides several important benefits.
Protects Exterior Surfaces
Removing mould and dirt prevents long-term damage to paint and cladding.
Improves Street Appeal
A clean exterior makes the entire property look newer and well maintained.
Prevents Expensive Repainting
Regular cleaning helps extend the lifespan of exterior paint.
Improves Property Value
Well-maintained homes create better first impressions and can attract more buyer interest.
How Often Should a House Be Washed?
Most homes benefit from professional house washing every 12–18 months.
Homes located near trees or coastal areas may require cleaning more frequently due to higher mould and salt exposure.
Why DIY House Washing Can Be Risky
Some homeowners attempt to clean their houses using DIY pressure washers.
However, incorrect pressure settings can cause damage such as:
- Stripping paint
- Forcing water behind cladding
- Damaging weatherboards
- Causing water intrusion
Professional soft washing ensures surfaces are cleaned safely.
