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.
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.
Specialised Soft Wash Technology
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.
Longer-Lasting Results
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.
Weed and Moss Control
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.
Gentle on Surfaces, Tough on Grime
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.
Fully Trained & Insured Technicians
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.
Eco-Friendly & Safe for Families and Pets
We only use biodegradable, environmentally responsible cleaning solutions that break down naturally after use. These are safe for children, pets, and plants when applied correctly — something we take very seriously.
Exceptional Customer Service
Our reputation is built on reliability, professionalism, and great results. From your first enquiry to the final clean, we’re committed to clear communication, punctuality, and making sure you’re 100% satisfied with the outcome.
Restores & Protects Your Investment
Your block paving is a valuable part of your property. Our cleaning service not only restores its natural colour and appearance but also extends its lifespan by preventing long-term biological damage. Clean, well-maintained paving enhances curb appeal and adds value to your home.

Thank you very much! Paul Welsh2025-04-22Trustindex verifies that the original source of the review is Google. We’ve used Softwashing a number of times over the past few years to clean the exterior of our house, gutters and patio. Every time it has been a fantastic service, always going above and beyond, whether it’s attacking a stubborn rust stain or taking time to explain the process. We have recommended them to friends and neighbours and using them every year is testament to how happy we are with the work they do. Thanks! Andrew Covell2025-04-11Trustindex verifies that the original source of the review is Google. The service was great, Gavin arrived on the dot of eight o’clock and he then talked me through the process before starting. He worked diligently using a range of different techniques to address the various issues. At the end the render looked like new! Would definitely recommend and will have them back again when it needs doing again! Peter Grant2025-03-29Trustindex verifies that the original source of the review is Google. As a director of and on behalf of Wardour Court Management Company and residents I wish to record our thanks to Gavin and his team. The property is a sensitive building constructed of Chilmark stone, it had not been cleaned for some time and was looking the worse for wear. They were all extremely efficient and professional as well as very pleasant and easy to talk to despite the difficulties they encountered, which included having to work 17 hours on one of the days. All the residents I have spoken to have expressed how pleased they are with the result, as are the directors of Wardour Court Management Co. We would happily use this company again and are equally happy to recommend them to others. Ann Grant Jewellery2025-03-29Trustindex verifies that the original source of the review is Google. Gavin and his team recently cleaned the Chilmark stone courtyard mews where I live. The stone was in dire need of cleaning and proved to be a very difficult job including one 17 hour day. Despite the difficulties he and his team remained pleasant, friendly and very professional leaving us with what I can only describe as a transformation ... our ugly duckling has become a swan. I can't thank them enough for their dedication and would happily recommend him and his company. City Stays sw Ltd2025-02-05Trustindex verifies that the original source of the review is Google. One of our properties, which is a rental, was a complete eye sore on the exterior surfaces, which needed rectifying before it was able to go back on the rental market. After ringing around different companies, Softwashing UK stood out and understood our requirements. Softwashing UK Soft wash cleaned 15 years' worth of bad organic staining from our K-Rend render, brickwork, and all rain water goods to the property. We honestly could not believe the results that were achieved. The render now looks like the day we had it rendered. On the day of the work ne carried out, the guys turned up on time and carried out the job respectfully and professionally. It's great to see good tradesmen still exist. We highly recommend the soft wash service they offer, and we will be sure to recommend Softwashing UK our friends and family's. James C2025-01-15Trustindex verifies that the original source of the review is Google. Very pleased with the job. Very professional. Had comments saying it looks like a new render job, it’s that clean! Thanks Matthew May2024-07-29Trustindex verifies that the original source of the review is Google. A fantastic company with an incredible passion and work ethic. They have a wealth of knowledge and experience that enables them to use the right product and application for different sites. We recently used them on a number of blocks in the Bournemouth area. As a block manager, their proactive view on CDM and H&S is first class.
