North Shore
Exterior mould removal on the North Shore
On the North Shore, the canopy that makes the streets so green also keeps walls, paths and roofs damp. Black mould and green algae follow. We treat it at the root and use gentle methods on heritage surfaces.
Sydney's humidity and shady gardens grow mould on anything that stays damp: south-facing walls, side passages, timber, stairs under trees. Rinsing it off with high pressure removes what you see but leaves the roots, and it's back within months.
We treat mould with a solution that kills it, give it time to work, then rinse. Slippery green paths and stairs are made safe again, and we point out the damp sources that keep feeding the growth.
Local detail
Mould removal across the North Shore
What we see in suburbs on the North Shore:
- Castlecrag: Mould and algae on shaded stone and timber.
- Lindfield: The canopy means leaf litter, shade and moss.
- Gordon: Shade and leaf litter are constant, and older roofs and gutters need regular attention.
- Woolwich: Sandstone, river damp and heritage rules all point to gentle, tested methods.
- Northbridge: Sandstone, tall trees and harbour-side shade mean mould, moss and leaf stains.
- Turramurra: We clear gutters and roofs before summer, clean pool areas and paving stained by the canopy, and wash homes on the shaded side.
How often
For mould removal, plan on near the water, every 12 months on shaded walls; under trees, every 12 months on shaded walls.
What affects the quote
- Heritage materials: test patches and lower pressure take longer than a modern build.
- Older materials: soft brick, original pointing and old paint mean gentler, slower methods.
- Waterfront: wash water near the shoreline may need to be contained and collected.

Nathan did a great job washing the external sides of our house. The weatherboard was dirty and had cobwebs. Nathan went above and beyond our expectations, the house was perfectly clean and all the cobwebs were gone.
Nathan did an incredible job at my home cleaning all my outdoor paving areas. He even washed some extra areas of my house free of charge and his price was very reasonable. He's a lovely fella and was prompt, friendly and professional. I highly recommend Nathan's services.
Nathan just completed a pressure wash of our travertine pavers under our alfresco area, around the pool and the sundeck. What an absolutely fantastic job. Nathan is punctual, knowledgeable, polite and left our place neat and tidy. We will certainly be calling him back on a regular basis and can highly recommend him.

Keep pets away until surfaces are rinsed and dry.
Can you remove mould from timber?
Yes, at low pressure with a timber-safe treatment.
Why are my stairs so slippery?
Algae. Treating it makes them safe again.
