Big Deal Exterior Cleaning

Lower & Upper North Shore · Sydney

Exterior cleaning in the North Shore.

Heavy tree cover across the North Shore keeps roofs and south-facing walls damp for most of the year, so lichen and black algae return faster here than almost anywhere else in Sydney. Gutters under mature gums generally need clearing twice a year.

Useful answers

North Shore questions.

Do you service the North Shore?
Yes. Big Deal Exterior Cleaning services the North Shore across 12 suburbs including Mosman, Cremorne, Neutral Bay, Chatswood, Lane Cove. We cover house washing, roof cleaning, gutter cleaning, window cleaning, pressure washing and solar panel cleaning throughout the region.
What exterior cleaning does a North Shore property usually need?
Heavy tree cover across the North Shore keeps roofs and south-facing walls damp for most of the year, so lichen and black algae return faster here than almost anywhere else in Sydney. Gutters under mature gums generally need clearing twice a year.
What is soft washing and why is it better for my house?
Soft washing is a gentle cleaning method that uses low water pressure — around 150 to 180 PSI, similar to a garden hose — combined with biodegradable cleaning solutions to remove dirt, mould, algae and grime from a home's exterior. Unlike pressure washing, it kills organic growth at the root rather than blasting it away, so results last four to six times longer and delicate surfaces like render, painted timber and roof tiles are not damaged.
How much does a professional house wash cost in Sydney?
Professional house washing in Sydney typically costs between $300 and $600 for a standard residential property. A two-bedroom home is usually $250 to $400 and a three-bedroom home $300 to $600. The final price depends on square metreage, the level of organic growth, access, and whether you add services like driveway or window cleaning. Every quote is free and given in writing before work starts.

Do I need to be home while you perform the service?
