That black stuff creeping up your retaining wall? A hose won't touch it. 👇
Gold Coast humidity does this to sandstone, blocks and pavers. Every wet season the mould spreads a little more, the pavers get slipperier, and the whole backyard starts looking tired.
This wall went from black and mossy to natural sandstone in one clean. Watch the flip at the halfway mark. 👀
What you get with a JetBlast clean:
✅ Mould and grime properly removed, not just blasted
✅ Safer, non-slip pavers
✅ A backyard you're proud to host in again
