Sandstone Cleaning in Vaucluse

In Vaucluse the sandstone cleaning work is mostly on sandstone terraces. Inter-war mansions and 1990s to 2020s harbourfront rebuilds on steep blocks, with sandstone retaining walls, rendered facades and long frameless-glass elevations. The defining problem here is salt from Port Jackson on one side and the Tasman on the other, so glass etches and sandstone greens on both aspects, which decides the chemistry, the pressure and how often the surface needs attention.

We work around Vaucluse House, Parsley Bay, Nielsen Park and the Hornby Lighthouse walk, on streets such as Wentworth Road, Hopetoun Avenue, Coolong Road and The Crescent. Salt spray is the dominant force on Vaucluse exteriors. Glass hazes within weeks, render streaks under sills and fixings rust-run within a season, and black algae colonises the shaded southern walls. We schedule Vaucluse homes on quarterly glass and six to twelve-monthly soft-wash cycles rather than waiting for the grime to become visible.

Woollahra Municipal Council. Woollahra has one of the highest concentrations of heritage-listed homes and Heritage Conservation Areas in Sydney. Many properties feature original sandstone, slate and terracotta that must be cleaned with low-pressure, chemical-controlled methods. Council also enforces strict stormwater rules: wash water cannot be discharged into gutters that drain to the harbour.
