Render cleaning is a specialist exterior cleaning service designed to restore the appearance of rendered surfaces on residential and commercial buildings. Over time, external render can become discoloured and unsightly due to a build-up of organic growth, air pollution, weather exposure, and general grime. Whether your property features K Rend, monocouche, silicone, or traditional cement render, regular cleaning is essential to maintain its aesthetic appeal and structural integrity.

In this blog, we’ll explain what render cleaning involves, why it’s necessary, and how professional render cleaning services can help protect your property for years to come.

Why Does Render Become Dirty?

Although render is chosen for its modern appearance and weather-resistant qualities, it is not immune to external pollutants. Several factors can cause render to deteriorate in appearance:

• Algae and moss growth: Green, red or black staining is typically caused by algae, lichens, or mosses thriving in damp conditions.
• Weathering: Rain, wind and UV exposure can gradually dull the colour of render and lead to staining.
• Pollution: Airborne particles from traffic, factories or nearby trees can settle on render surfaces.
• Efflorescence: White, chalky marks may appear when salts migrate to the surface and crystallise.

These stains can make your property look aged or neglected and, in some cases, can contribute to damage over time.

What Does Render Cleaning Involve?

Render cleaning is not as simple as using a pressure washer. In fact, high-pressure washing can often cause more harm than good by damaging the surface of the render or driving moisture deeper into the structure. That’s why the recommended approach is a soft washing technique — a low-pressure application of specially formulated cleaning solutions.

The Typical Render Cleaning Process:

1. Assessment: A professional will assess the condition and type of render on your property.
2. Preparation: Any surrounding areas are protected, and a biocide treatment may be applied to prevent regrowth of organic matter.
3. Application of Cleaning Solutions: Special cleaning agents are applied using low pressure to break down algae, moss and dirt.
4. Soft Wash Rinse: The area is rinsed gently to remove contaminants without damaging the surface.
5. Final Treatment (if required): A protective treatment may be added to inhibit future growth of algae and fungi.

This method is safe for most types of render and produces lasting results without compromising the integrity of the wall surface.

Benefits of Render Cleaning

Investing in professional render cleaning offers a wide range of benefits:

• Improved kerb appeal: A clean, bright exterior creates a more attractive and well-maintained impression.
• Increased property value: First impressions count – particularly if you’re thinking of selling or renting.
• Extended lifespan of the render: Removing organic growth can help prevent decay and erosion.
• Cost-effective maintenance: Regular cleaning reduces the likelihood of needing costly repairs or re-rendering.
• Environmentally friendly solutions: Reputable companies use biodegradable and non-harmful products.

How Often Should Render Be Cleaned?

There is no fixed timescale, as this depends on your property’s location and exposure. For example, buildings near trees or in damp, shaded areas may experience faster algae growth and require more frequent cleaning. However, a thorough render clean every 2–3 years is often sufficient for most homes and businesses.

Why Choose a Professional Render Cleaning Company?

While some homeowners may consider cleaning render themselves, there are risks involved in using the wrong equipment or chemicals. An experienced render cleaning company, such as Simple Clean, will:

• Use industry-approved techniques and products
• Avoid causing damage to your render or surrounding surfaces
• Ensure the job is completed safely and efficiently
• Provide expert advice tailored to your building
