Signs your render needs work
Cracks in the render
Cracks let water into the wall behind — a direct route to internal damp.
Blown or hollow patches
If it sounds hollow when tapped, the render has lost its bond and will fail.
Staining & damp inside
Damaged render often shows up as damp on the inside of the wall.
Tired, patchy pebbledash
Discoloured or missing dash makes a house look dated and lets moisture in.

What our customers say
Rendering & roughcasting FAQs
What’s the difference between render and roughcasting?
Roughcasting (harling) is the traditional textured wet-dash finish; render can be smooth or silicone. Both weatherproof the wall — we’ll advise what suits your home.
Will new render stop my damp?
If the damp is coming through cracked or blown render, yes — sealing the wall properly stops water getting in.
Can you match my existing finish?
Yes — we match roughcast texture and colour, or re-dash pebbledash, so repairs blend in.
How long does render last?
A well-applied render or harling finish lasts decades with little maintenance, especially modern silicone renders.
