growth of algae,
mould, and other organic matter on rendered surfaces. These issues not only affect your property's appearance but can also lead to long-term damage if left untreated. Our render cleaning services address these challenges, helping you preserve your property's value and curb appeal.

Eco-Friendly Cleaning Methods
Soft Washing: Gentle Yet Effective
Soft washing is our primary method for cleaning rendered surfaces. This technique uses low-pressure washing combined with specialised cleaning solutions and biocides.
It's particularly effective for delicate surfaces like lime and silicone renders.
Benefits of Soft Washing:
- Gentle on render surfaces, preventing damage
- Effectively removes algae, moss, and mildew
- Ensures thorough cleaning while protecting the environment
Our soft washing process involves spraying the cleaning solution onto the render and allowing it to dwell for approximately 15 minutes before rinsing with clean water. This method ensures a deep clean without risking damage to your property's exterior.
Pressure Washing: Power and Precision
For more robust render types like cement and acrylic, we offer pressure washing services. This method uses high-pressure water jets to clean the surface of the render effectively.
Advantages of Pressure Washing:
- Highly effective at removing stubborn dirt and grime
- Ideal for tougher render surfaces
- Quick and efficient cleaning process
Our experienced technicians are trained to use pressure washing equipment safely, ensuring optimal cleaning results without damaging the render.
Chemical Cleaning: Targeted Solutions
For particularly challenging stains or organic growth, we employ chemical cleaning methods. Our team uses specialised, environmentally friendly cleaning agents that break down dirt, algae, and other contaminants without harming the render or surrounding landscape.
Benefits of Chemical Cleaning:
- Effective at removing tough stains and organic growth
- Tailored solutions for different render types
- Safe for the environment when used correctly
