Render Cleaning in Gloucester, Cheltenham, Stroud and The Cotswolds

We safely work on all types of render systems from through colour, thin coat silicone to Ewi. K-rend, Wetherby, Parex to name a few can all be safely cleaned with no damage to the substrate. We use Hse approved products that deliver results safely.

Algae on render can come in different forms and react differently to soft washing depending on the method used. We can decide which approach on our first visit and consultation.

Green stains disappear very quickly as they are often the first sign of organic staining taking hold. Red algae bursts with colour as the cells break down. Black staining is often a Metabolic stain that the Algae produces. It gives the algae UV protection and allows the algae to grow happily underneath. These are a little more stubborn and require rinsing between treatments. A hot wash down under low pressure is used to remove the built up organic matter and often Moss/Lichen that has started to grow on the renders surface.
