Driveway & Paver Cleaning Melbourne

That grey-black film on a Melbourne driveway is almost never dirt. It is a living layer of algae, mould and lichen feeding on moisture, and it comes back fast if you only blast the top off it. South-facing driveways, anything under a tree, and paths beside a fence line are the worst affected because they simply never dry out.

We pre-treat with a biocide and let it work before any water touches the surface. That kills the growth at the root rather than just removing the visible layer, which is the difference between a driveway that stays clean for a year or two and one that is grey again by the next wet season.

Engine oil that has been sitting on unsealed concrete for years has soaked into the slab, and no amount of pressure pulls it back out. It needs a degreaser and hot water, sometimes a poultice, and sometimes it will lighten substantially rather than vanish. We will tell you honestly which of those we expect before you commit to the job.

Rust runs from garden furniture, reo chairs or fixings need an acid-based rust remover, not pressure — pressure alone just polishes the surface around the stain.

Cleaning a paved area removes jointing sand along with the weeds and moss. Left that way the pavers lose their interlock and start to rock and spread. We top the joints back up with kiln-dried or polymeric sand as part of the job.

Sealing is optional and worth considering on exposed aggregate, decorative concrete and light-coloured pavers. A good seal makes the next clean far easier, resists oil penetration, and holds jointing sand in place. It is quoted separately because it needs a fully dry surface, which usually means a return visit.
