How softwashing works

  1. Check the surface

    We identify the surface and choose the right solution and strength for it.

  2. Protect

    Windows, doors and nearby plants protected before we start.

  3. Apply at low pressure

    The solution goes on gently and gets to work on the growth.

  4. Let it work

    Given time to dwell, it breaks down algae, moss and staining at the root.

  5. Rinse and photos

    A gentle rinse, a tidy up, and your before and after photos.

Softwash or pressure wash?

Two different tools for two different jobs. We choose the right one for each surface, so nothing gets damaged and everything comes clean.

Softwashing

Cleaning solutions applied at low pressure. Kills moss, algae and lichen at the root, and keeps working after we leave.

  • Render, cladding and painted walls
  • Fascias, soffits and delicate finishes
  • Anywhere a jet wash could cause damage
About softwashing

Pressure washing

High-pressure water for tough, hard-wearing surfaces. Strips back years of dirt, weeds and grime quickly.

  • Block paving and concrete driveways
  • Steps, paths and yards
  • Hard-wearing patio slabs
About pressure washing

Why softwash?

  • No surface damage

    Low pressure means no etching, no stripped paint and no water forced behind panels.

  • Kills growth at the root

    It treats the cause, not just the surface staining you can see.

  • Stays cleaner for longer

    Because the growth is killed off, it takes longer to come back.

  • Safe for delicate finishes

    Ideal for render, painted walls and anything a jet wash could harm.

All FAQs
What is softwashing?

It's a cleaning method that uses specialist solutions at low pressure, rather than high-pressure water, to kill moss, algae and lichen and lift the staining they cause.

Why not just pressure wash?

High pressure can erode render, strip paint and force water behind cladding. Softwashing gets the surface clean without that risk, and it kills the growth rather than just moving it.

Will softwashing damage my render?

No. That's the point of softwashing: the finish isn't blasted, so it isn't damaged.

How quickly will I see results?

Most staining lifts on the day. Some deeper staining keeps fading over the following days as the treatment finishes working.

Is it safe around my plants?

We protect plants and planted borders before we start and rinse around them afterwards.
