Limestone Cleaning in Watsons Bay

In Watsons Bay the limestone cleaning work is mostly on weatherboard and render, sandstone walls. Fishermen's cottages, weatherboard and rendered homes and a handful of modern rebuilds on the peninsula. The defining problem here is the most exposed address in the Eastern Suburbs, with salt on every elevation and timber that needs gentle treatment, which decides the chemistry, the pressure and how often the surface needs attention.

We work around Camp Cove, The Gap, Robertson Park and the Hornby Lighthouse, on streets such as Military Road, Cliff Street, Pacific Street and Marine Parade. Salt spray is the dominant force on Watsons 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 Watsons 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.
