In Wahroonga the sandstone cleaning work is mostly on sandstone. Grand Federation and inter-war estates on large blocks with tennis courts, sandstone walls and long driveways. The defining problem here is deep shade and leaf fall from the canopy that keeps courts, drives and stone permanently damp, which decides the chemistry, the pressure and how often the surface needs attention.

We work around Wahroonga Park, Knox Grammar, Abbotsholme and the Fox Valley bushland, on streets such as Burns Road, Water Street, Braeside Street and Cleveland Street. The tree canopy over Wahroonga drives most of the work we do here. Leaf litter fills gutters twice a year, tannin stains sandstone, driveways and paths, and moss and lichen take hold on stone and tennis courts in the shade. Stone, gutter and driveway programs on a 9 to 12 month cycle keep these properties ahead of the growth.

Ku-ring-gai Council. Ku-ring-gai Council is one of Sydney's greenest LGAs, with heavy tree canopy across Wahroonga, Pymble, Killara and St Ives. Roofs, gutters and driveways accumulate leaf litter, lichen and black algae quickly, and large blocks mean long driveways and tennis courts that benefit from professional cleaning and sealing. Many properties sit in bushfire-prone areas where gutter and roof debris removal is a safety task, not just an aesthetic one.

Our method in Wahroonga

How we clean it, and how we protect everything around it

A quaternary ammonium or hypochlorite biocide is applied and left to work for 20 to 30 minutes, then the surface is brushed and rinsed at under 500 psi with a fan nozzle. Rust from ironstone inclusions is treated with a reducing poultice. No acid is used.

Pressure capped at 500 psi on all sandstone
Lime mortar joints protected
Carved detail brushed by hand
Heritage documentation on request

I recently had my brick pavers cleaned by Prestige Standard and I couldn't be happier with the results. The team was professional, punctual, and paid great attention to detail. My pavers went from looking dull and stained to fresh and almost brand new again.
