The result after cleaning the roof and exterior render

Exposure to the weather, moisture, shaded areas and nearby vegetation can encourage algae, moss, lichen, mould and other organic growth to develop on exterior render. Over time, dirt and atmospheric pollution can also cause staining and discolouration, leaving the building looking tired and neglected.

Professional render cleaning is suitable for both residential and commercial properties where the exterior has lost its original appearance due to this build-up.

How do we clean exterior render safely?

Not all types of render and levels of dirt require the same cleaning method. Before starting the work, we assess the surface to choose the right method and avoid using unsuitable pressure or treatment.

Choosing the right cleaning method for the surface

Before cleaning, we check:

Based on these factors, we determine the right method for each job.

Why high-pressure washing can damage render

Render is more sensitive than hard surfaces, and using too much pressure can:

Low-pressure cleaning and treatment

Depending on the condition of the render, we can use:

The aim is to clean the surface effectively, without using aggressive methods and without treating every type of render in the same way.

What types of render can be cleaned?

We use safe methods tailored to the surface for most render systems, including:

We assess the condition of the surface before cleaning, as the method needs to be adapted to the type and age of the render, as well as any damaged or sensitive areas.

Not sure if your render can be cleaned?

We carry out a free site survey before any work begins, so we can assess the surface and let you know what’s possible.

    Render cleaning FAQs

    In general, exterior render should be cleaned around every 2 to 3 years, although the exact timing will vary from one property to another. North-facing walls, shaded areas, high moisture levels, nearby vegetation and the level of contamination can all mean that more frequent cleaning is needed.

    Yes, you can clean small, easily accessible areas yourself if the dirt is light or there is only a small amount of green growth. You can use water, a mild detergent and a soft brush. However, avoid high-pressure washers and harsh chemicals, as these can damage the surface. For larger, hard-to-reach or heavily contaminated areas, it is safer to use a professional.

    Yes, professional render cleaning can be worth the investment when the surface is affected by algae, staining or other organic build-up. A professional can choose the right method for the type and condition of the render, use suitable equipment and treatments, and clean areas that are harder to reach.

    Spring and early autumn are usually the best times to clean render, as mild temperatures and stable weather help cleaning treatments work effectively. However, render can be cleaned at other times of the year when conditions are suitable.

    Yes, render should be cleaned before painting. Dirt, algae and loose material can prevent the new coating from bonding properly to the surface. The render should also be checked for any damaged areas before painting begins.
