What is Softwashing?

Soft washing is a safe and very effective low-pressure cleaning & sanitising method, for both domestic and commercial properties.

It uses low pressure equipment that will effectively clean, and sanitise exterior surfaces with a variety of biodegradable chemicals. Soft washing chemicals can be applied at the correct measurements and ratios for quick and lasting effects on most surfaces.

These surfaces include:

  • Natural stone and brickwork
  • All types of roofs
  • Block paving, patios, and concrete.
  • K Rend, rendered walls
  • Pebbledash, roughcast, tyrolean/stucco
  • Slate roofs and tiles where moss can be suitably scraped off prior to application
  • Fences, decking, and timber cladding
  • Summer houses and Oak buildings
  • Industrial cladding
  • PVC plastic cladding, fascias, and soffits
  • Rubber crumb play areas.

Each individual surface with distinct contaminants requires a tailored soft washing solution for best results.  Our solution is mixed on-site for optimal results for the task required. This way we customise our approach to maximise the results whilst also achieving cost-effectiveness.

Soft washing targets the organic growth behind discoloration and staining. Most of the dirt on properties is a living organic bio film or carbon deposit. Weather, pollution and the environment can cause significant damage to the surface/render on your building, with moss growth, algae and pollution build up causing serious damage if left untreated.

Soft washing will kill the spores and treat unwanted biological growth of fungus, moss, red and green algae, bacteria, lichen, pollen, mould and other forms of growth on the target surface.

The chemicals are Eco-friendly and do not “bio accumulate”, meaning they break down rapidly on contact with soil to give it a very low environmental footprint. The work area is rinsed and is perfectly safe for children and pets etc.

Our machines work at 145psi maximum which is about the same as a household tap. This means there is no damage to delicate surfaces or pointing. Using a high-pressure washer on render or such surfaces can cause tremendous damage opening up the surface to create a further more porous surface for additional colonisation of algae etc and often striping of the surface. We can reach high elevations up to 10 meters using full carbon fibre water-fed poles, with either nozzles or brushes fitted.  Above that height we have access to platforms or cherry pickers should we need them.

This means it can keep surfaces clean for up to 5 years following treatment, depending on weather conditions and position of the property.
