Exterior Softwashing


Our Softwashing Service

Lancashire Softwash provide a professional softwashing service for rendered surfaces and buildings that use metal sheet cladding or engineered cladding boards.

Both render and cladding will over time become dirty or discoloured. This is primarily caused by a build up of environmental impurities or biofilms and leads to a build up of red, green or black deposits made up of algae or moss which are difficult to clean without specialists equipment and products.

We have worked closely with the major render manufacturers for over 20 years and our technicians are some of the most experienced in the region, we often work directly with the manufacturers to provide our softwashing service throughout Lancashire, Manchester, Cheshire and parts of North Yorkshire.

Our Exterior Softwashing Process

The softwash cleaning technique breaks down in to two main parts.

  1. We clean your building with steam heated to 150°, applied at low pressure to eradicate stubborn stains without damaging the render and paintwork of your property.
  2. We then use HSE approved biocide chemicals designed to eliminate algae and discolouration and prevent the growth of organic materials that can stain your walls.
  3. Our softwash service is usually combined with a render seal coating to complete the treatment, this ensures that the rendered surface can continue to ‘Breathe’ but any moisture is prevented from passing through. For more information on our render sealing service please click here.

Still Not Sure?

We offer a no obligation site visit and quotation for our softwashing service and we are happy to provide a patch test to demonstrate the expected outcomes, for more info or to arrange an appointment please contact us.

Lancashire Softwashing FAQs

Softwashing is a gentle and effective exterior cleaning method that uses low-pressure water combined with eco-friendly cleaning solutions to remove dirt, mold, algae, and other contaminants from surfaces. Unlike pressure washing, which uses high-pressure water to blast away debris, softwashing is a safer and more suitable option for delicate surfaces like roofs, cladding, render and painted exteriors. Softwashing ensures thorough cleaning without causing damage to the surfaces being treated.

The most heavily stained sides of your property are likely to be the north and east sides. This isbecause they will not be exposed to quite as much natural sunshine as other sides. Green staining can be particularly prevalent on areas near water, as increased humidity can lead to more infections. The problem can be exacerbated as spores arrive from nearby large foliage like trees.

To give an accurate time estimate we would need to assess the property. On average our softwashing service is completed in one to two working days, although a follow-up visit may be required on some occasions.

Unfortunately not. The problem is that, while this approach to cleaning render will wear down its surface, it won’t completely eradicate spores. As a result, those left will simply re-grow even thicker – and more quickly – than before. Soft washing, however, will get rid of even micro-organic spores leaving your walls pristine. 

Absolutely! We have fully qualified rendering specialists within the business who repair and patch damaged render. All the major rendering suppliers ensure our work and come with the supplier’s guarantee. We can even provide a full rendering service on request with competitive pricing.

Softwashing kills all algaes, bacterias and moss. This gives your surfaces a fresh start and protects it from rapid regrowth. We would be confident to say that it will stay clean for another two years. Some areas will grow back quicker though due to shade or overhanging tree branches. We recommend that softwashing be carried out every 3 years to keep your property looking its best.

Softwashing not only cleans your walls but kills any organic growth at the root, leaving you with longer-lasting pristine walls. Softwashing can effectively remove a whole range of contaminants including: stains, algae, mould, spores, carbon deposits, UV-damaged surfaces, moss, and lichens.

Yes, softwashing is an environmentally friendly cleaning method. The cleaning solutions used in softwashing are typically biodegradable and designed to be gentle on the environment. The low-pressure water application also minimizes the risk of water and chemical run-off, making softwashing a sustainable choice for exterior cleaning. It effectively removes contaminants without compromising the surrounding ecosystem.

A4: Yes, softwashing is designed to be safe for plants and landscaping. The cleaning solutions used are typically formulated to minimize harm to vegetation. Additionally, the low-pressure application ensures that the cleaning process is gentle on surrounding plants and does not cause damage. Softwashing not only effectively cleans surfaces but also prioritizes the protection of your landscaping, making it a suitable choice for exterior cleaning around gardens, lawns, and other greenery.
