Render cleaning across Portishead
We cross the Severn from Barry to clean render across Portishead — the marina, the newer waterside developments and the older town — where modern K-Rend and silicone finishes are everywhere.
Portishead render and the estuary air
Right on the Severn estuary, Portishead is exposed to damp, salt-laden coastal air that greens up render fast, especially the pale K-Rend on its many new-build homes. Our low-pressure soft wash clears the staining and treats the surface for a longer-lasting, damage-free finish.
How our soft washing works
On every Portishead 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.
