Sandstone Cleaning Sydney | Low Pressure, No Pitting or Scarring

Sydney sandstone is soft. That is why the city is built from it and why so much of it is ruined by cleaning. High pressure cuts the face off the stone, leaving a pitted, lightened surface and scoured-out mortar joints. It is not reversible — the only remedy is redressing or replacing the stone.

How sandstone should be cleaned

Low pressure, with a treatment that draws the black staining and biological growth out from within the stone rather than blasting the surface off it. It is slower and it looks less dramatic on the day, but the stone comes back to its own colour rather than to a raw, freshly cut face. On heritage work and lime mortar this is the difference between a clean and a repointing bill.

What we clean

Retaining walls and garden walls, steps and stepped paths, sandstone paving and flagging, pool surrounds, heritage facades and window sills, and the capping and coping that takes the most weather.

Sealing

Sealing after cleaning slows reabsorption and makes the next clean easier, particularly on horizontal surfaces and anything under tree canopy. It is optional, and we will tell you where it is worth it and where it is not rather than adding it to every quote.

Where we work

Sandstone cleaning across the Eastern Suburbs, the North Shore and the Northern Beaches — harbourside and heritage properties in particular.
