Roughcast, often referred to as harling, is a popular exterior wall finish used on homes and commercial buildings throughout the UK. It is known for its durability and ability to withstand harsh weather conditions. However, due to the UK’s damp climate, roughcast surfaces can quickly become covered in algae, moss, lichen, and atmospheric pollution.
Over time this organic growth causes unsightly staining, making properties look tired and poorly maintained.
Our roughcast soft wash cleaning service in the UK provides a safe, effective, and long-lasting solution to remove these contaminants and restore the original appearance of your exterior walls.
Using specialist soft washing techniques, we clean roughcast surfaces without the risk of damage caused by high-pressure jet washing.
Soft washing is a professional exterior cleaning method designed for delicate surfaces such as render, roughcast, pebble dash, and stone. Instead of relying on high pressure, soft washing uses specially formulated cleaning solutions applied at low pressure to break down organic growth and dirt.
This approach allows contaminants to be removed safely while protecting the structural integrity of the roughcast.
Soft washing effectively removes:
Because the treatment eliminates spores at their source, it also helps slow down the return of algae and biological growth.
Soft washing removes unsightly staining and restores the natural colour of your roughcast walls, dramatically improving the look of your home or building.
Unlike pressure washing alone, soft washing uses specialised treatments that continue to work after cleaning to slow the regrowth of algae and moss.
Removing organic growth helps prevent moisture retention that can gradually weaken and deteriorate roughcast surfaces.
Clean exterior walls enhance the overall appearance of your property, making it more attractive to visitors, neighbours, or potential buyers.
Regular roughcast cleaning can reduce the need for expensive repainting, repairs, or render replacement in the future.
We inspect the roughcast surface to identify areas affected by heavy algae, moss, or staining and determine the most suitable cleaning approach.
Loose debris, moss, and surface contaminants are carefully removed prior to treatment.
Specialist cleaning solutions are applied using low-pressure equipment to break down organic growth and dirt embedded in the render.
The surface is carefully rinsed to remove contaminants while protecting the integrity of the roughcast.
A professional biocide treatment is applied to help prevent the rapid return of algae and biological growth.
