Key Benefits of Our Render Cleaning Service

Safe for All Render Types: Whether your property has K-rend, monocouche, or cement renders, we have the right solution.
Improves Property Value: A clean, well-maintained exterior boosts your property’s kerb appeal and overall value.
Prevents Long-Term Damage: Regular cleaning prevents algae and moss from degrading the render and causing structural issues.
Our Render Cleaning Process
Our process begins with an on-site assessment to determine the specific type of render and the level of dirt or algae present. We then apply a specialised cleaning solution that penetrates deep into the surface, breaking down organic growth and dirt. This is followed by a low-pressure wash that gently rinses away contaminants without damaging the render.
Step 1: On-site Assessment: Tailored solutions based on render type and condition.
Step 2: Application of Cleaning Solution: Deep-penetrating cleaner to break down algae, moss, and dirt.
Step 3: Low-Pressure Wash: Safe and gentle washing to remove contaminants and restore your surface.
Why Regular Render Cleaning Is Essential
Over time, render surfaces can become dull and discoloured due to weather exposure and organic growth. Algae and moss not only degrade the appearance but can also penetrate the render, leading to cracks and expensive repairs. Regular cleaning:
- Protects your property’s exterior.
- Prolongs the lifespan of the render.
- Enhances the appearance and value of your property.
