Barry render and the sea air
Right on the coast, Barry’s salty sea air accelerates algae, lichen and black staining on render, especially the K-Rend and silicone finishes on newer seafront homes. Low-pressure soft washing clears the growth and treats the surface so it stays clean, without the cracking a jet wash can cause.
How our soft washing works
On every Barry 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’.
