Render Crack Repair in Coleraine
Diagnosing and repairing hairline, map and structural cracking in existing render.
We carry out render crack repair across Coleraine and the surrounding Londonderry area throughout the year.
Most of what we see around Coleraine reflects the wider Londonderry pattern — Victorian terraces, harled cottages and exposed north-coast housing, and driving rain and salt on north-coast properties.
Coleraine sits in a part of the UK that gets wet with severe Atlantic exposure on the north coast — worth factoring into any render decision. The north coast around portstewart takes direct atlantic weather, and dash finishes substantially outperform smooth render there.
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 Coleraine
Do you take a deposit?
For most domestic jobs we take a deposit to cover materials and scaffold, with the balance on completion. Terms are set out clearly in the written quote.
Can you match my existing render?
Usually, yes. We colour and texture match as closely as we can, though weathered render never matches a fresh batch exactly — we will be honest about how visible a patch will be.
What causes cracks in render?
Shrinkage during curing, an over-strong mix, thermal movement, missing movement joints, substrate movement, or genuine structural movement. The pattern tells you which.
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.
