Softwashing is a specialist exterior cleaning method that uses low-pressure water combined with biodegradable cleaning solutions to safely remove algae, mould, lichen and biological growth from delicate surfaces. Unlike [pressure washing](/services/pressure-washing), which relies on force to blast dirt off surfaces, softwashing works chemically — killing organisms at their root and preventing regrowth for significantly longer. This distinction is critical for surfaces like render, K-rend, pebble dash, painted masonry and timber cladding. These materials are easily damaged by high-pressure water, which can strip paint, erode surface coatings, force water behind the render and even crack the finish. Softwashing delivers superior results with zero risk of surface damage — which is why it's the method recommended by most render and cladding manufacturers. ## Why South Wales Properties Need Softwashing South Wales has a climate that's practically designed to encourage biological growth on external surfaces. The combination of high rainfall, mild winters and limited direct sunlight on north and east-facing elevations means algae, mould and lichen colonise rendered walls within just a few years of application. Properties in [Newport](/areas/newport), [Cardiff](/areas/cardiff), [Cwmbran](/areas/cwmbran) and the surrounding valleys are particularly affected. Green algae streaks on white render are the most common complaint, but red algae, black mould and grey lichen are also widespread. These organisms don't just look unsightly — they trap moisture against the wall surface, which can lead to render failure, cracking and long-term damp problems. Regular softwashing removes these growths and protects your render's integrity. ## Surfaces We Softwash - **Render and K-rend** — smooth, textured and scraped finishes - **Pebble dash** — the loose aggregate surface common on older Welsh homes - **Painted masonry** — exterior painted brick and blockwork - **Timber cladding** — natural and treated timber exteriors - **Composite cladding** — modern composite panel systems - **UPVC** — fascias, soffits, bargeboards and cladding panels - **Conservatory frames and roofs** — see our dedicated [conservatory cleaning](/services/conservatory-cleaning) service ## Softwashing vs Pressure Washing — Which Do I Need? The choice between softwashing and pressure washing depends entirely on the surface being cleaned. Hard surfaces like concrete, block paving and natural stone are ideal candidates for [pressure washing](/services/pressure-washing) — they can withstand high-pressure water without damage. Softer, coated or delicate surfaces — render, paint, timber, cladding and UPVC — should always be softwashed. In many cases, a property benefits from both methods on a single visit. For example, we might pressure wash the [driveway](/services/driveway-cleaning) and [patio](/services/patio-cleaning) while softwashing the rendered walls and cleaning the [UPVC fascias](/services/upvc-cleaning). This combined approach gives you a complete exterior transformation. ## How Long Do Softwash Results Last? One of the biggest advantages of softwashing is longevity. Because the cleaning solution kills biological growth at its root — rather than just blasting the visible layer off the surface — regrowth takes significantly longer. Most softwashed surfaces stay clean for 2–4 years, compared to 6–12 months for surfaces cleaned with pressure washing alone. Factors that affect longevity include the surface's orientation (north-facing walls regrow faster), proximity to trees and hedgerows, and local humidity levels. ## Is Softwashing Safe for Plants and Pets? We use biodegradable cleaning solutions that break down naturally after application. During the process, we protect nearby plants, lawns and garden features with covers and careful application technique. Pets should be kept indoors during the application phase and for a short period afterwards while surfaces dry. Once dry, treated surfaces are completely safe for people and animals. ## Areas We Cover for Softwashing We provide professional softwashing throughout South Wales, including [Newport](/areas/newport), [Cardiff](/areas/cardiff), [Cwmbran](/areas/cwmbran), [Pontypool](/areas/pontypool), [Caerphilly](/areas/caerphilly), [Chepstow](/areas/chepstow), [Caldicot](/areas/caldicot), [Magor](/areas/magor) and [Bristol](/areas/bristol). ## How Much Does Softwashing Cost? Softwashing prices depend on the size of the area, the type of surface, the level of growth and accessibility. A typical semi-detached house with rendered walls costs between £360 and £850 for a full softwash. Detached properties, commercial buildings and multi-storey structures are quoted individually.
