Without regular maintenance, weeds (the most tenacious of plants) will grow in between paving slabs, typically taking root in the dust and sand between the blocks.
Only in very rare instances will weeds actually grow through paving blocks; the notorious Japanese Knot Weed will grow through blocks up to 200 mm thick, for example.
The good news is that this means a simple softwash treatment will remove weeds from your blockwork and paving, and the integrity of the surface is unlikely to be compromised by weed growth.
While high pressure washing can only blast the weed away, and risk damaging the block along with nearby vegetation, our softwash biocide blends will kill weeds. A softwash treatment also typically lasts three times longer than a high pressure wash.
We also remove unsightly growth from block paving, namely algae. Green algae can look unsightly, and over time it will also prove a slip hazard.
Unfortunately the solutions you can buy over the counter to remove it are ineffective, as they do not not offer sufficient concentrations of biocide, and specialist treatment is therefore required.
At Softwashing UK we will use DDAC biocides, and steam at low pressure (as recommmended by Historic England), to remove all kinds of organic growth, restoring block paving to optimum condition.

Algae, which is particularly present and persistent on limestone block and paving across the West of the UK, can also be treated. We will use super low pressure and a specialised blend of softwash detergents to both kill and remove all traces of algae.
Lichens, which use a combination of symbiotic processes to establish and colonise a block or paving slab, are even more persistent. They are most common on concrete and sometimes on limestone, but less frequently on granite or other igneous rock types.
The tenacity of lichens will require far more than a high pressure blast to remove them and with higher pressures comes more risk of damage. At Softwashing UK, we use specialised detergent blends, often with an ammonium component, to ensure the lichen’s removal and destruction.
This requires expertise, and our adherence to health and safety is paramount.
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:
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.
Block paving is a popular choice for driveways, patios, and walkways — and for good reason. It’s attractive, durable, and adds real value to your property. However, over time, block paving can become discoloured with algae, moss, weeds, and general dirt build-up. That’s where Softwashing UK comes in.
We provide a professional, results-driven block paving cleaning service using advanced soft washing techniques — a safer, longer-lasting alternative to pressure washing.
Unlike high-pressure cleaning that can damage your block paving and disturb the jointing sand, we use a low-pressure soft wash system combined with eco-friendly cleaning solutions. This method cleans deeply into the pores of the surface, removing algae, moss, and biological growth at the root without causing erosion or surface wear.
Our soft washing method doesn’t just make your block paving look clean — it actually keeps it clean longer. By eliminating the spores and bacteria that cause growth, we delay regrowth and reduce the need for frequent maintenance. This means your paving stays pristine for months instead of weeks.
We don’t just clean your paving; we treat it. Our biocidal treatments kill off weeds, moss, and lichen at their source, stopping them from returning quickly. This proactive approach keeps your driveway or patio looking neat and tidy without relying on harsh chemicals.
High-pressure washing can sometimes do more harm than good — loosening bricks, stripping off jointing sand, and roughening surfaces. Our soft wash method is gentle enough for even older or weathered block paving, yet powerful enough to fully clean and sanitise the area.
When you choose Softwashing UK, you’re getting certified professionals. Our team is fully trained in the latest soft washing techniques, health & safety practices, and chemical handling. We’re also fully insured for residential and commercial properties, giving you peace of mind every step of the way.
