How Much Does Render Cleaning Cost in the UK? (2025 Pricing Guide)
Introduction
Render cleaning is no longer a luxury, it’s a necessity. Especially across Kent, Essex, Surrey, East and West Sussex, and London, the damp climate means your rendered building can go from pristine to patchy in just a few months. But what does it actually cost to clean render safely, without damage or risk?
In this 2025 guide, we break down the main factors affecting the price of professional render cleaning, what you should expect to pay, and how to ensure your property is treated with care.
In this 2025 pricing guide, we break down what affects the cost of render cleaning and what you should expect to pay for a professional service.
What Affects the Cost of Render Cleaning?
Several factors determine the final price for render cleaning:
Size of the Property:
Larger buildings cost more due to the extra labour, equipment, and cleaning solution required. Quotes are usually based on square metres.
Type of Render:
Not all render is the same. K-Rend (see official K-Rend maintenance guide), Monocouche, Weber, and other silicone-based renders each need different cleaning methods. Delicate or painted finishes may require extra care.
Access Requirements:
Do we need scaffolding, MEWPs, or rope access to reach upper levels? These logistics affect time and cost.
Degree of Soiling:
A light green dusting of algae is quicker to remove than years of black staining and lichen. Heavy soiling means longer dwell time and often multiple treatments.
Location:
Jobs in central London vs Tunbridge Wells, for example, vary in travel time and access restrictions, which can impact price.

Commercial vs Residential Render Cleaning Costs
The cost of render cleaning varies significantly between homes and commercial sites. Homeowners often receive simpler quotes—based on size, access, and soiling. Commercial projects are a different beast. Large façades, high access requirements, and tight schedules all add complexity. That’s why every commercial render clean almost always requires a bespoke site survey and quote.

After Render Cleaning Apartment Block
Letting algae and grime build up doesn’t just look bad, it can damage the surface, leading to much more expensive refurbishment later. In severe cases, full re-rendering could cost tens of thousands, regular cleaning prevents this.
How often should render be cleaned?
Most properties need cleaning every 3–5 years, but exposed or shaded walls may require more frequent attention.
Can I pressure wash my render myself?
No. High-pressure washing can destroy the finish and force water into the wall, causing hidden damage. Always use a professional soft washing company who will test porosity and select the correct mix.
