When do render cracks need repairing?

  • Cracks in the render or monocouche
  • Damp on the inside wall
  • Pieces of render coming loose
  • Cracks that keep growing

What the crack repair includes

  • Assessing each crack

    We tell shrinkage, thermal and structural cracks apart before starting work.

  • Raking out and cleaning

    We open the crack into a V, remove loose material and clear the dust.

  • Flexible sealing

    A flexible filler or mortar that moves with the wall without reopening.

  • Reinforcing mesh

    Glass-fibre mesh embedded in mortar where cracks keep coming back.

  • Render reinstatement

    Monocouche or render of the same type as the original, with a similar texture.

  • Final protection

    Breathable paint or water repellent so water cannot get back in.

Façade cracks in Sant Joan Despí: why they appear

On terraced and detached houses in areas such as Centre, La Mossota and Residencial Sant Joan, 1990s and 2000s monocouche shows map cracking, cracks where columns meet brickwork and diagonals running from window corners. There, glass-fibre mesh is what stops them returning.

Before touching anything, on façades in areas such as Pla del Vent, Torreblanca and Les Begudes we measure the width and direction of each crack and check whether it is still active. Diagonal cracks, cracks through the wall or cracks that keep growing go to an engineer before repair.

On the visit we check every crack and give you a detailed written quote with the repair system; a site manager coordinates access and the team. We also repair cracks in nearby areas: Cornellà de Llobregat, Sant Feliu de Llobregat and Esplugues de Llobregat.

Frequently asked questions

01

Exterior render crack repair in Sant Joan Despí: which areas do you cover?

We do this work in Sant Joan Despí, in areas such as Centre, La Mossota, Residencial Sant Joan, Les Planes, Pla del Vent, Torreblanca and Les Begudes, and also nearby: Cornellà de Llobregat, Sant Feliu de Llobregat and Esplugues de Llobregat. Before starting we visit the property and prepare a detailed written quote.

02

Are all façade cracks serious?

No. Most come from shrinkage or thermal movement in the render and are repaired with sealing and mesh. If we see diagonal cracks, cracks running through the wall or cracks that keep growing, we recommend having a surveyor check the structure first.

03

Why is filling the crack not enough?

If the crack is not opened up and sealed with a flexible material, movement in the wall makes it show again. That is why we rake it out, clean it and add mesh where cracks keep recurring.

04

Will the repair be visible?

We match the texture of the render as closely as we can, but new colour almost always stands out. That is why we usually recommend repainting the whole section afterwards.
