Residential Render Cleaning (Softwashing)

Softwashing UK are dedicated to delivering external cleaning services, and render cleaning, to domestic customers across the UK. We are renowned for our excellent rates and attention to detail. 

We clean render, all kinds of cladding, stone, roofs, patios, gutters, and more. Domestic properties often become contaminated with organic growth. While this can be down to architectural defect more often than not it is down to the natural conditions. 

Organic growth can occur on nearly all external substrates. It most often takes the form of single cell green algae, red algae, or black mould. Lichens and all kinds of fungi can become established as time progresses too, as well as moss.

We specialise in cleaning and treating the organic growth that becomes established on domestic properties. We use softwashing technology that removes stains on buildings without the risk of high pressure.

What is Softwashing?

When looking for a quote for cleaning your domestic property it is best to send Softwashing UK as much information as possible so we can compile a quote for you quickly. 

We will need your address and postcode, and we if you are able to send photos of your property that will be very helpful. From this information we can often compile a quote. 

In some cases we may need to arrange to see your property in person to review access, or complete test patches. Many domestic properties can be cleaned from the safety of the ground without for access equipment, and this helps us keep costs as competitive as possible.

We use various technologies to clean your domestic property. One of the most common is the use of the Doff Steam System, which is ideal for restoration and cleaning. 

It is particularly effective at stone restoration. We also use biocides and outdoor cleaning solutions that are not available through retail outlets and only available to trained professionals.

Our Render Cleaning Methods

Softwashing Uk treats every job as its own individual project, as such, the most suitable method will be proposed in our quotation. Over the many years we have been restoring render, we have found that the cleaning of it falls in to five categories:

1. Render Restoration

This service is used when the render has not been cleaned for many years and the render is heavily stained with black mould, blackspot and lichens, as per the sliding photograph.

This method requires every square inch of the render to be low-pressure washed, or steam cleaned and treated with stain remover, multiple times to achieve the desired finish.

This service is our render restoration service above, followed by our biocide render
treatment service, below in point 5.

This service is for your day-to-day cleaning of render, that has average organic staining i.e. green, red and some black staining in areas. An example of this is showed in the
photographs.

This service is for your day-to-day cleaning of render which is followed by a biocide
treatment, to help keep the render cleaner for longer.

The application of a high quality HSE approved professional use only biocide. A biocide
treatment will help keep render looking clean, while reducing the need for more intensive
and expensive render restoration cleaning, at a later date. 

Specialist biocide treatments for render are essential for maintaining the appearance and durability of render. Homeowners often underestimate the impact of weather on render. Over time, harsh conditions can lead to cracks, discolouration, and mould growth.

Applying anti-fungal solutions, prevents mould and algae growth. It’s crucial to address these problems early, as they can worsen over time. 

Our professional-grade biocide acts fast against biological growth on all external hard surfaces, breaking the reproductive cycle of microbial surface contaminants.

Why Choose Softwashing UK For Render Softwash Cleaning Services?

Roughcast is a popular exterior finish used on homes across the UK thanks to its robust nature and coarse, textured appearance. However, over time, roughcast walls can become stained and discoloured by algae, moss, lichen, and general grime. That’s where Softwashing UK comes in.

We offer professional roughcast cleaning using specialist soft washing technology — a safer, longer-lasting alternative to pressure washing.

1. Specialised Soft Wash Technology

Unlike high-pressure cleaning, which can loosen or erode the roughcast surface and damage the render, our low-pressure soft wash system uses biodegradable cleaning solutions that penetrate deep into the textured finish.

This method safely kills algae, moss, and organic growth at the root without damaging the roughcast.

Our soft washing doesn’t just make your roughcast look clean — it prevents the return of organic growth by eliminating spores and bacteria. This means your walls stay cleaner for longer, reducing the need for frequent maintenance.

We don’t just clean — we treat. Our softwash solution includes a powerful biocidal treatment that destroys moss, algae, and lichen at the source, ensuring your roughcast remains clear and protected from recurring growth.

High-pressure washing can seriously damage roughcast by stripping away the finish or exposing cracks in the render. Our soft wash method is gentle enough for older or more delicate surfaces while being powerful enough to remove years of staining and biological buildup.

When you choose Softwashing UK, you’re choosing fully trained, certified, and insured professionals. Our team is experienced in treating roughcast walls with the correct softwashing techniques and is trained in safe chemical handling and property care.

Our cleaning solutions are pH neutral, fully biodegradable, and environmentally responsible. They’re completely safe for children, pets, and surrounding vegetation when used correctly — a key priority for every job we undertake.

We pride ourselves on delivering reliable, professional service from start to finish. From your first enquiry to the final inspection, you’ll experience clear communication, punctuality, and results that exceed expectations.

Cleaning your roughcast not only improves the appearance of your home but also helps protect the structure underneath. Our service prevents damage caused by biological growth and extends the life of your exterior finish — all while boosting curb appeal.
