Soft Washing

Green staining and algae on render, brick and cladding build up over the years. Soft washing uses low pressure to clean the surface without the damage a pressure washer can cause.

What's included

Soft Washing, done properly

  • Low-pressure cleaning for render, brick and cladding

  • Removes green staining and algae without damage

  • Safe for painted and rendered surfaces

  • Ideal before a repaint or for general upkeep

Our process

How we clean it

  1. Assess the surface

    We check whether the wall is render, brick, cladding or another material, to choose the right approach.

  2. Apply a low-pressure clean

    Water is applied at low pressure, so there's no risk of forcing water behind render or damaging pointing.

  3. Treat staining and algae

    Stained or algae-covered areas are treated so the discolouration lifts, rather than just being pushed around.

  4. Rinse and finish

    A final rinse leaves the surface clean without the etching or damage a pressure washer can cause.

Tools & equipment we use

  • Low-pressure washing equipment
  • Surface-appropriate cleaning solution
  • Soft brushes for stubborn areas
  • Purified water for rinsing

Our recommendation

Soft washing is a gentler alternative to pressure washing, particularly on render, older brick or painted surfaces. It's often worth doing before a repaint, since it removes algae that would otherwise show through new paint.
