In Mosman the stone sealing work is mostly on sandstone walls, pool terraces. Federation and inter-war homes on large blocks, harbourfront rebuilds and quality strata along Military Road. The defining problem here is sandstone fences and steps that green under tree canopy, and harbour-facing glass that salt-etches, which decides the chemistry, the pressure and how often the surface needs attention.

We work around Taronga Zoo, Chinamans Beach, Bradleys Head and the Military Road village, on streets such as Military Road, Raglan Street, Prince Albert Street and Cowles Road. Salt spray is the dominant force on Mosman 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 Mosman homes on quarterly glass and six to twelve-monthly soft-wash cycles rather than waiting for the grime to become visible.

Mosman Municipal Council. Mosman Council protects a large number of Federation and Inter-war homes under heritage controls, and foreshore properties fall under harbour catchment rules. Tree canopy is dense, so roofs and sandstone retaining walls here carry heavy lichen and organic staining that responds best to soft-wash treatment rather than high pressure.

Our method in Mosman

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

Stone is cleaned and dried for 48 hours, moisture tested, then sealer is applied by low-pressure sprayer and back-brushed. A second coat follows wet-on-wet or after cure depending on product. Excess is buffed off to avoid residue.

Breathable products only on sandstone and limestone
Excess removed to avoid haze
Pool and garden protected
Dry weather window confirmed

What clients say

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.

We are extremely happy about Nathan's work. Our house is totally transformed after he pressure jet the place. The sandstone stairs and surround have restored to its former glory. Driveways are like new.
