Sandstone Cleaning in Warrawee

In Warrawee the sandstone cleaning work is mostly on sandstone. Federation mansions on large blocks in the Warrawee conservation area, with sandstone, slate and render. The defining problem here is heritage sandstone and render in deep shade, where only conservation-grade methods are appropriate, which decides the chemistry, the pressure and how often the surface needs attention.

We work around Knox Grammar, Warrawee Bowling Club and the Pacific Highway heritage streets, on streets such as Cherry Street, Heydon Avenue, Warrawee Avenue and Woonona Avenue. The tree canopy over Warrawee 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.
