Render Cleaning in Cardiff
Red, green or black marks on your walls? That’s algae, and it does more than look bad — it holds moisture against your render. We soft wash all render types safely, with no damage to the surface, for homes and commercial buildings across Cardiff and South Wales.
01 — Overview
Why render cleaning matters
Your render is one of the most significant parts of your property. It protects your brickwork from water damage — and when algae takes hold, it doesn’t just look unsightly, it can contribute to damp inside the home.
We’ve been cleaning render and stone across Cardiff for over 20 years, on both residential and commercial premises. Our philosophy has always been simple: be straightforward with clients, keep pricing completely clear with no hidden extras, and deliver the best possible clean at an unbeatable cost.
Every member of the team is fully insured, uniformed, and communicates with you at each step of the job. Need your windows done at the same time? Our accredited window cleaners in Cardiff can handle that on the same visit — and we clean gutters too.

05 — Questions
Render cleaning FAQs
What is soft washing?
Soft washing cleans render using low pressure and specialist cleaning solutions rather than a high-pressure jet. It lifts algae, moss and dirt without forcing water into the surface, so your render is cleaned thoroughly with no damage.
Will render cleaning damage my render?
No. Because we soft wash rather than use high pressure, there’s no deterioration to stone or render. The method is safe on all render systems, including delicate silicone-based finishes.
Why has my render gone green, red or black?
Those marks are algae. Beyond looking unsightly, algae holds moisture against your render, which can contribute to damp inside the home. Soft washing removes it and helps protect the surface.
What types of render can you clean?
All of them — K Rend, Weber and Monocouche, pebble dash and traditional render, stone and stonework, and silicone-based systems. We also clean commercial fronts, signage, cladding and walls.
