How Exterior Cleaning Is Priced
Exterior cleaning companies typically base their prices on the following factors:
1. Property Size
Larger properties require more labour, cleaning solution, water, and equipment.
2. Property Condition
Heavy mould, algae, moss, lichen, grime, or spider webs can increase cleaning time and treatment requirements.
3. Access and Height
Double-storey homes, steep sections, tight access, high roofs, and difficult working areas may require additional equipment and safety measures.
4. Surface Type
Weatherboard, plaster, brick, metal, concrete, timber, and other surfaces require different cleaning methods and levels of pressure.
5. Cleaning Method
Soft washing is generally used for delicate exterior surfaces, while water blasting is more suited to durable surfaces such as concrete and some paving.
6. Location
Prices can vary by region due to travel, labour, and local operating costs.
7. Additional Services
Roof treatment, gutter cleaning, window cleaning, driveway cleaning, and other services increase the total price when added to a house wash.

Check whether the advertised price includes GST. Some providers list prices before GST.

Roof Cleaning and Roof Washing Cost NZ
Roof washing is priced on inspection rather than by a fixed size-based rate. The final price depends on the roof condition, size, access, height, and cleaning requirements.
Roof washing is different from roof treatment:
- Roof treatment uses a treatment solution to address moss, mould, algae, and lichen.
- Roof washing involves physically cleaning the roof surface.
A roof inspection is required to determine the appropriate cleaning method and provide an accurate price.
