Sandstone restoration that brings the natural colour back

Careful cleaning, restoration and sealing for sandstone walls, steps and features across NSW.

Sandstone wall before and after moss removal

Sandstone is soft and porous. It soaks up moisture and grows moss and algae, and high pressure will wear the face of the stone away. We restore it with a careful soft wash instead.

We check the age and condition of the stone first and adjust the mix to suit it. Moss is scraped off by hand, the stone is treated and rinsed gently, and a second treatment goes on if it needs one. Sealing afterwards helps it stay clean.

What you get from sandstone restoration

  • The original colour of the stone back

Our sandstone restoration process, in seven steps.

  1. 1 of 7

    Condition check

    We assess the age and condition of the stone to set the mix ratio.

  2. 2 of 7

    Plant check

    We look at the surrounding plants and plan how to protect them.

  3. 3 of 7

    Plant protection

    Nearby plants are wet down and neutralised.

  4. 4 of 7

    Moss removal

    Visible moss is scraped off with a rubber scraper.

  5. 5 of 7

    Treatment

    The stone is pre-wet and treated to break down dirt and growth.

  6. 6 of 7

    Second protection

    Plants are neutralised again during the clean.

  7. 7 of 7

    Gentle rinse

    A careful rinse, then a second treatment if the stone needs it.

Why sandstone needs a gentler clean than concrete.

How the stone behaves

  • It is porous and soaks up moisture and dirt
  • It is soft, so high pressure wears it away
  • Every stone differs, so the treatment has to as well
  • Older stone needs a weaker mix

What we usually fix

  • Moss and algae in damp, shaded spots
  • Weathering and discolouration
  • Staining from trees and plants
  • Damage from earlier pressure washing
