Green and black growth — moss, algae, mould and lichen — thrives in Sydney’s humid, shaded spots. It looks untidy and can make surfaces slippery. Effective removal treats the growth, not just the surface.
What our moss, dirt & algae removal service covers
- Paths, stairs and driveways
- Walls, fences and retaining walls
- Roofs (see roof soft washing)
- Pool surrounds and patios
Benefits
- Safer, less slippery surfaces
- Cleaner, brighter exteriors
- Treatment aimed at the growth itself, not just the stain
How we approach the job
We apply a suitable treatment to break down organic growth, allow dwell time, and then remove it with pressure appropriate to the surface — high pressure for robust concrete, low pressure or soft washing for roofs, render and delicate stone.
Things to know before you book
- Growth will return over time in shaded, damp areas; improving sunlight and drainage helps.
- Some lichen and black staining fades over the weeks after treatment.

Frequently asked questions
Why does moss keep coming back?
Moss and algae grow where surfaces stay damp and shaded. Cleaning removes them, but the conditions that encourage them usually remain.
