Advance Render Cleaning covers Aberdare and the Cynon Valley for render and soft washing, travelling up from our base in Barry. Valley properties take the brunt of damp, shaded air, so render here greens over quickly with algae and moss — from older pebbledashed and rendered terraces to modern render estates. Our low-pressure soft wash and biocide treatment clears the growth and slows its return, without the pressure washing that damages K-Rend and coloured finishes.

Aberdare render and the valley climate
High in the Cynon Valley, Aberdare sees heavy rainfall and damp, sheltered air that let algae, moss and black staining thrive on render. Low-pressure soft washing removes the growth and treats the surface, so the finish lasts far longer than a jet wash.
How our soft washing works
On every Aberdare job we use the same low-pressure soft washing method — biodegradable biocide, never high-pressure jet washing that can crack or streak render. See how we clean render and K-Rend safely on our render cleaning and soft washing page, or call 01792 823663 for a free quote.

Pressures washing and Soft washing are effective ways to wash} your property exterior. However there a some things you must consider when choosing which:
- Pressure washing utilizes highly pressurized water which forcefully removes grime and dirt from the surface that it comes into contact withs. This shows immediate results HOWEVER it will pose any significant}property damage over time. For example, cracks in the render once penetrated by water can freeze and expand, thus causing render to full ‘blow’.
- Soft washing uses low pressure which avoids and potential damage, results can take 24 hours, and the biocide continues to penetrate the bacterial growths.
Our professionals know that softwashing long term attains the safer and longer lasting clean result.
