Render and Cladding Cleaning

Render and cladding are popular building finishes but are easily affected by algae, pollution and weathering. Professional cleaning restores appearance and protects the surface from long term damage.
This guide explains how building and facade washing works, the methods used by professionals, and how businesses benefit from regular exterior cleaning. It also covers the safest way to clean brickwork, render, cladding, metal panels and glass facades without causing damage.

Why Render Becomes Dirty
Render absorbs moisture and becomes a perfect growing environment for algae and mould. Pollution and weather also cause streaks and discolouration.
Soft Washing for Render
Render should never be cleaned with direct high pressure. Soft washing uses low pressure and a safe cleaning solution to remove algae and staining.


Cladding Cleaning Methods
Cladding materials include:
- Aluminium
- Steel
- Composite
- UPVC
- Powder coated metals
Each requires a different cleaning method such as soft washing, steam cleaning or low pressure rinsing.
Steam Cleaning and DOFF Systems
Steam cleaning is used for delicate surfaces or historic cladding. It removes contamination using low pressure and high temperature.


Benefits of Render and Cladding Cleaning
- Restores appearance
- Removes algae and black staining
- Protects against long term deterioration
- Maintains property value
- Improves kerb appeal
