About RenderClean

Most homes don’t get “dirty” overnight.

The staining you see on render, walls and exterior surfaces is usually caused by organic growth — algae, mould and lichen — which builds up gradually over time. It’s especially common on shaded or north-facing walls where moisture sits longer.

Left untreated, it spreads. What starts as light staining turns into heavy discolouration that makes the whole property look tired.

That’s where we come in.

How Our Process Works

We don’t just wash surfaces — we treat the cause of the problem.

Our process typically involves:

  • Careful assessment of the surface and level of contamination

  • Application of a specialist cleaning solution to break down organic growth

  • Gentle rinsing (where required) to avoid damage to render or finishes

  • Optional biocide treatment to kill remaining spores and slow regrowth

This approach restores the appearance of your property without the risks of aggressive pressure washing.

Why Choose RenderClean

There are plenty of people offering “jet washing”.

That’s not what this is.

We focus on:

  • The right method for the surface (not one-size-fits-all)

  • Longer-lasting results, not just a quick visual fix

  • Child, pet and plant friendly - provisions to protect what’s important

  • Turning up, doing the job properly, and leaving everything tidy
