Pressure Washing in Drummoyne

Council's plan of management describes Drummoyne as a broad, low sandstone peninsula with interlinked ridgelines, steep side slopes and rock outcrops along the foreshore. The rock can become part of the home itself: a heritage assessment records one waterfront lot on Wolseley Street terraced into several levels cut from the rockface, with a sandstone fence and piers, a sandstone garage and sandstone-floored balconies. Where a sloping block has sandstone steps, landings or retaining walls, they need far gentler handling than the concrete beside them.

Sandstone is porous, and on the shaded side slopes and foreshore it stays damp. Moss and algae root into the surface, and a green film on stone steps turns slippery well before it looks serious. The weathered face of the stone carries its colour, so it is cleaned at far lower pressure than concrete, with the setting matched to each surface.

The street trees bring their own stains. Camphor laurels along Cometrowe Street drop small dark berries that get crushed into paths and driveways, and the Moreton Bay figs on Bayswater Street shed fruit and broad leaves onto everything beneath them. Brush box, the suburb's common street tree, can leave tannin marks where its leaves lie wet on concrete. Strata buildings add shared driveways with oil stains and tyre marks, and common paths that take foot traffic every day.

On a sloping block the hard surfaces are the way from the street to the front door, and a terraced lot can have several flights of steps between levels. Clearing moss and algae from them is a safety job first. Wet sandstone carrying a green film is treacherous in a way flat concrete rarely is, and it is the route taken every day with shopping, bins and children.

For strata buildings the same reasoning covers common paths and the driveway, where the owners corporation answers for a surface every resident walks on. Oil stains and tyre marks on a shared driveway also make an otherwise tidy building look neglected from the street.

Stone cleaned at the right pressure keeps its weathered face, colour and texture, and does not come away carrying lance marks that will outlast the clean by decades. That is the difference between restoring a sandstone wall or step and quietly damaging it.

Pressure cleaning is also the preparation a surface needs before sealing, so if you are planning to seal pavers or a sandstone terrace, a thorough clean comes first. Every job is quoted on area, surface and build-up, and you receive before-and-after photos when it is finished.
