Render Repair and Cracked Render

Most render repairs are cracks, hollow patches or stains. Small repairs are priced after a look, usually by the day (€200–€300 for a plasterer); if more than a few patches have come away, re-rendering the wall is often better value.

What the cracks mean, how a repair is done, and when to re-render instead.

What the cracks are telling you

What you see	Usually	The fix
Fine hairline cracks in a web	The finish shrank as it dried	A flexible coating, or nothing
One straight crack along a joint	Movement between blocks, or at a lintel	Cut out, mesh, patch
A crack with a bulge, or a hollow ring	Render coming away from the wall	Hack off the patch and re-render it
Wide or stepped cracks that grow	Possible movement in the wall	An engineer first, then the render
Green or black streaks	Algae where water runs	A biocide wash; fix the drip

A patch rarely matches perfectly. On a painted wall it disappears under the paint; on a coloured render, the contractor may suggest doing the whole wall in one go so there's no visible line.

What repairs cost

Supplied and applied, per square metre of wall, and for whole houses.

Questions we get asked

How much does render repair cost?

It depends on the size. Small repairs are priced after a look, often by the day: €200–€300 for a plasterer, €350–€500 with a labourer.

Are cracks in render serious?

Fine hairline cracks usually aren't. Cracks with a bulge, a hollow sound, or wide cracks that grow need a look, and a wall that's moving needs an engineer.

Can you patch silicone render?

Yes, but a patch can show. Many contractors re-coat the whole wall in the finish so it's one even colour.
