Sandstone Cleaning in Double Bay

In Double Bay the sandstone cleaning work is mostly on sandstone fences. Art-deco and 1960s apartment buildings, Victorian villas and new boutique strata along the bay. The defining problem here is strata facades and balcony glass facing the harbour, with narrow laneway access for equipment, which decides the chemistry, the pressure and how often the surface needs attention.

We work around Steyne Park, Redleaf Pool, Cross Street and the Bay Street village, on streets such as Cross Street, Bay Street, Ocean Avenue and William Street. Salt spray is the dominant force on Double Bay 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 Double Bay 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.
