Render Crack Repair in Lisburn
Diagnosing and repairing hairline, map and structural cracking in existing render.
If you are weighing up render crack repair in Lisburn, the starting point is what your walls are actually built from.
Most of what we see around Lisburn reflects the wider Antrim pattern — Victorian brick terraces, harled cottages and postwar estates, and driving rain and dash render failure on exposed elevations.
With wet with strong Atlantic and Irish Sea exposure, specification matters more in this part of the country than a national price list suggests. Dash render is close to universal on northern irish housing, and matching existing dash is the most common requirement on repair work.
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 Lisburn
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.
