Render Crack Repair in St Austell
Diagnosing and repairing hairline, map and structural cracking in existing render.
Render Crack Repair in St Austell is work we take on regularly, and the Cornwall housing stock is a big part of why.
Across Cornwall, granite and cob cottages, slate-hung walls and exposed coastal housing dominates, and driving-rain penetration and salt damage on exposed elevations is what we are called out to most often.
Local conditions bring severe driving rain and salt-laden coastal exposure, and that has a direct bearing on which systems are worth specifying. Exposure here is category-defining — dashed and roughcast finishes genuinely outperform smooth render on west-facing coastal walls.
When render crack repair is the right call. Choose crack repair when the render is otherwise sound and well-bonded but cracking is letting water in or spoiling the appearance.

FAQs
Render Crack Repair in St Austell
When do cracks mean structural problems?
Diagonal cracks from window and door corners, cracks wider than about 5mm, cracks that are visibly growing, or cracking matched by internal cracking. Those need a structural engineer, not a renderer.
How long does a rendering job take?
A typical three-bedroom semi is usually one to two weeks on site including scaffold, preparation, application and finishing. Weather, wall condition and the system chosen all move that.
Do I need planning permission to render my house?
Usually not on a standard house, but you will if the property is listed, in a conservation area, or if rendering would significantly change its appearance. We flag it at survey.
Will you need scaffolding?
For anything above single storey, yes — it is safer and produces a better finish than working off ladders or towers. Scaffold is included and itemised in the quote.
How long before I can paint new render?
Through-coloured systems need no painting at all. Sand and cement should cure for around 28 days before masonry paint goes anywhere near it.
