Our Render Cleaning Methods

Soft washing that’s safe, effective, and tailored to your surface.

We use a proven, low-pressure soft washing system that gently breaks down and removes staining.

Our render cleaning method includes:

Biocidal treatment to kill organic growth at the root
Low-pressure application to avoid damage or streaking
Specialist equipment to access awkward areas safely
Optional re-treatment plans to prevent regrowth

We never use high-pressure washing on render, which can strip protective coatings and cause lasting damage. All work is carried out by fully trained operatives using appropriate access equipment, including MEWPs, scaffold towers, and long-reach poles. We work in full compliance with health and safety standards, and every job is fully insured for your peace of mind.

Why Render Cleaning Matters

Looks better. Lasts longer. Costs less in the long run.

A dirty render not only looks unprofessional, but it can also trap moisture and encourage organic growth, ultimately leading to long-term deterioration. Therefore, regular cleaning helps to:

Remove algae, moss, lichen and red/black staining
Improve kerb appeal and property value
Protect the integrity of render and finishes
Save money on repainting or full re-rendering

Whether you manage a commercial property or own a home, keeping your render clean is a simple and cost-effective way to maintain your building’s exterior.

Frequently Asked Questions

Our Render Cleaning FAQs

No. We use a gentle, non-abrasive soft washing process specifically designed for render. The reason for this is that it safely removes dirt and growth without harming the surface or colour.

Through our professional render cleaning techniques, we can remove green algae, red streaks, black mould, pollution build-up, and general weathering. A biocidal wash also helps prevent regrowth.

Most properties benefit from render cleaning every 2-3 years, depending on their location and exposure. Buildings near trees, main roads, or damp areas may need more frequent cleaning.

We work across South Wales and the South West, including Cardiff, Swansea, Newport, Bristol, Bridgend, Barry, and all surrounding towns.
