Render Cleaning Specialists in Swansea
M and S Cleaning provides professional render cleaning for homes, businesses, and managed properties across Swansea and South Wales. Modern render systems, including K-Rend, Monocouche, silicone, and painted finishes, are designed to give buildings a clean, attractive appearance, but they are also vulnerable to staining and biological growth.
Over time, coloured render can become stained with black discolouration. This is caused by a fungus growing on the surface. Red staining is caused by a species of algae and is very common in the coastal areas of South Wales. We can clean away this staining, leaving your render looking fresh and clean.
We use gentle chemical-based cleaning or Softwashing to clean render, and sometimes a gentle steam rinse is required to remove residual staining and get the render looking brand new.
Our safe render cleaning methods remove organic growth and surface contamination without damaging the render or forcing water into the structure. Using suitable softwashing and low-pressure cleaning systems, we restore your exterior, improve kerb appeal, and help protect the render from further deterioration. Whether your property is a family home, apartment block, retail unit or commercial site, we can restore the render to a clean, bright and well-maintained condition.
Why Render Becomes Stained
Render is exposed to constant moisture and weathering. Over time, this leads to:
- Green algae growth on shaded or damp walls
- Red and black staining caused by bacteria and pollutants
- Weather marks, rust streaks and dirt from surrounding surfaces
- Discolouration where rainwater runs down the render
- Reduced kerb appeal and a tired building appearance
Treating these issues early prevents further damage, protects the render surface, and keeps your property looking its best.

How We Clean Render
Render requires a careful approach, so we begin by assessing the condition of the walls, the staining present, and the specific render system used. This allows us to choose a safe and effective cleaning method that will remove growth and contamination without damaging the surface.
Once the assessment is complete, we apply a tailored softwashing solution that targets algae, red and black staining, mould, lichen and biofilm at their source. Softwashing uses low pressure, which prevents cracking, surface erosion and water ingress—problems commonly caused by unsuitable high-pressure washing.
Where areas are heavily soiled or affected by long-term pollution marks, we may use controlled steam cleaning to lift stubborn deposits while still protecting the render. After treatment, the surface can be rinsed to remove loosened growth, leaving the render looking cleaner, brighter and more uniform in colour. This approach not only restores the building’s appearance but also slows future regrowth, helping keep your property in good condition for longer.
