Render painting and re-coating in Rainham. Cleaned, stabilised and coated with breathable masonry paint or a full re-coat system. Fixed quotes.
A sound render that has gone green and chalky needs cleaning, stabilising and coating, not replacing — and that costs a fraction of the alternative. Near the river, algae is the usual culprit and it looks far worse than it is.
Washed down, treated for algae, stabilising primer where the surface is chalky.
On solid walls the coating has to let moisture out, or you cure the look and cause the damp.
Where a thin coat will not do, a proper re-coat gives a new finish without stripping the render.
If the render underneath is failing, coating it is money wasted and we will say so.

Usually not, and near the river in Rainham it is very common. Algae is a damp-and-shade problem, not a structural one. Cleaning, treating and coating costs far less than re-rendering.
On a modern cavity wall, often yes. On a solid interwar wall a non-breathable paint traps moisture in the brick and you get damp inside.
Ten years or so on a properly cleaned and stabilised wall, two on one coated over algae and chalk. The preparation is the job.
