Why use soft washing on render rather than a pressure washer?

Render and K-rend have a thin coloured surface that high pressure tears straight off, leaving patches you cannot fix without re-rendering. Soft washing uses a low-pressure spray and a biocide that breaks down the algae and grime chemically, so the wall comes clean without being damaged. It also reaches the spores in the surface, which is why it stays clean far longer than a blast would.

What causes the green and black staining on render?

The green is algae and the black streaks are usually a mix of algae and dirt washing down from blocked gutters or worn detailing. North-facing and shaded walls get it worst. Cleaning lifts the staining, and the treatment slows it coming back, but if a gutter is overflowing onto the wall it is worth sorting that at the same time.

Will the clean damage my plants or the paintwork?

We wet down and protect planting near the wall before we start and rinse it afterwards, and the products break down rather than lingering. Soft washing is gentle on sound paintwork and pointing. If anything is loose or flaking we will tell you before we start rather than make it worse.

Render and facade cleaning that does not wreck the surface

The quickest way to ruin a rendered wall is to point a pressure washer at it. We clean render, K-rend, pebbledash and brick across South London by soft washing, which lifts the green and the black streaks without stripping the surface, and treats the wall so it stays clean for years rather than months. Most jobs also turn up a blocked gutter or worn detail feeding the staining, and we will flag that so the problem does not just come straight back.
