Render Cleaning

Our render cleaning services

Render cleaning across the UK: low-pressure soft wash cleaning for silicone, K-Rend, monocouche, acrylic and painted render, removing green algae, black mould and staining.

Silicone render cleaning

Silicone render cleaning removes green algae, black mould and dirt from silicone thin-coat render using low-pressure application of a biocide and a gentle rinse, so the water-repellent surface is not stripped. It suits newer homes, extensions and estates finished in silicone render. A typical semi-detached house usually costs £300 to £600 in the UK.

Monocouche render cleaning

Monocouche render cleaning removes algae, mould and dirt from through-coloured single-coat render using a low-pressure biocide treatment and an even rinse. It suits homes finished in monocouche systems that have gone green, grey or streaky. Cleaning a typical semi-detached house usually costs £300 to £600 in the UK, depending on area, height and growth.

Painted and sand-and-cement render cleaning

Painted and sand-and-cement render cleaning removes algae, mould and dirt from traditional render and masonry paint using low-pressure biocide treatment and rinsing. It suits older homes with painted render that has gone green or grey, and anyone preparing render for repainting. Cleaning a typical semi-detached house usually costs £300 to £600 in the UK.

Pebbledash and Tyrolean cleaning

Pebbledash and Tyrolean cleaning removes algae, moss, lichen and dirt from textured render finishes using a biocide given a longer dwell time, rather than high pressure that can dislodge stones and texture. It suits older homes with pebbledash or spar dash and properties finished in Tyrolean render. A typical semi-detached house usually costs £350 to £700 in the UK.

Render rust, run-off and stain removal

Render stain removal treats specific marks that a general biocide clean does not shift, including orange iron staining, red or orange algae, streaks under sills and copings, and atmospheric dirt, using a cleaner matched to the cause. It suits homes with discoloured patches on otherwise clean render. Spot treatment usually costs £100 to £300 in the UK, or less alongside a full clean.

Protective treatment for render

A protective render treatment is a biocidal or water-repellent product applied to clean render to slow algae, mould and dirt coming back. It suits shaded, north-facing or tree-lined walls that green up quickly after cleaning. A protective treatment typically adds £1 to £3 per square metre to a render clean in the UK, depending on the product and render type.
