Repair & Rendering

External rendering and brickwork repair that fixes what's actually causing the damage, not just what's visible on the surface.

Repair & Rendering by GML Construction in North London

Cracked render is usually a symptom, not the problem

Render cracks and brickwork damage on older properties are very often a sign of an underlying issue — damp, movement, or a previous repair done with the wrong material for the wall type. Patching over it without addressing the cause means it comes back within a year or two.

We check for damp and structural movement before quoting a render or brickwork repair, and we'll tell you plainly if a patch is genuinely all that's needed or if there's something bigger to sort first.

What's included

  • External render repair and full re-rendering
  • Brickwork repointing and repair, lime or cement as appropriate
  • Damp diagnosis before any cosmetic repair work
  • Crack monitoring and repair for settlement-related damage
  • Weatherproofing and finish coats matched to the property

Matching materials on period properties

Lime render and traditional brickwork behave very differently to modern cement-based products, and using the wrong one on a period property is a common cause of trapped damp. We match the original material specification wherever the property calls for it, not just whatever's quickest.

Common questions

Why does my render keep cracking?

Recurring cracks are usually down to movement, damp trapped behind the wrong render type, or a previous repair using an incompatible material. We diagnose the cause before quoting, not just the visible crack.

Should older properties use lime render instead of cement render?

Often yes — lime render lets a solid brick wall breathe, whereas modern cement render can trap moisture and cause worse damp problems long-term. We'll advise based on your specific property's construction.

How long does external rendering take?

A full house re-render typically takes 1–2 weeks depending on property size and weather, plus curing time before any final decoration.
