Render cleaning across Chepstow
On the England-Wales border in the Wye Valley, Chepstow mixes period, stone and rendered homes. We clean render and K-Rend across the town and surrounding villages, travelling in from Barry for a free survey.
Chepstow render and the river-valley climate
The damp, wooded Wye Valley keeps Chepstow’s air moist, ideal for algae, moss and lichen to settle on render and stone. Our low-pressure soft wash removes the growth and treats the root, keeping surfaces clean far longer than pressure washing.
How our soft washing works
On every Chepstow 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.
