Gentle cleaning for slabs, stone, and paving
Algae and mould prevention
Restores colour without damage
Why your patio needs specialist care
Patio cleaning is more than a simple jet wash, particularly with the unpredictable British weather. Over time, patios collect algae, moss, lichen, and grime that not only dull the appearance but also create slippery, unsafe surfaces. We use controlled pressure and soft wash techniques to clean paving safely without loosening joints or damaging the surface.
Our methods effectively lift built-up dirt and organic growth while protecting the integrity of stone, concrete, and block paving. This restores the natural colour and finish of your patio, instantly making the area brighter and more inviting. Whether it’s a residential garden in Tonbridge or a commercial outdoor area, our service is tailored to the material and condition of the surface. We also take care around surrounding exterior features, ensuring your entire outdoor space looks clean, uniform, and well maintained.

How we keep your patio safe and looking its best
Johnson Exterior Cleaning focuses on removing organic growth that causes staining, surface erosion, and slippery conditions. Using a combination of gentle pressure and specialist softwash treatments, we remove moss, algae, mould, and ingrained dirt without damaging paving or jointing.
Our patio cleaning process is suitable for stone slabs, concrete paving, block paving, and decorative surfaces, making it ideal for both domestic and commercial properties. By controlling water pressure, we avoid common issues such as joint sand loss or surface wear. Our aim is to leave your patio cleaner, safer underfoot, and looking revitalised—ready to enjoy with family, friends, or customers.
Long-term benefits of professional patio cleaning
Regular patio cleaning helps prevent long-term damage caused by algae growth and trapped moisture. A clean surface reduces the risk of slips and falls, improving safety for everyone using the space. Our careful cleaning methods help maintain the condition of your patio, extending its lifespan and reducing the need for costly repairs or re-laying.
By restoring the patio’s natural colour and finish, we enhance your property’s kerb appeal and create an outdoor area that’s ideal for relaxation, entertaining, or everyday use.
