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.
What each crack tells us before we repair it
In 1960s and 70s blocks in areas such as Sants, Sants - Badal and Hostafrancs a horizontal crack at each floor level, where the frame meets the brickwork, is typical. We repair it on ropes or from the balconies once the residents' association has approved the work.
Where cracks recur, on render in areas such as La Bordeta and La Font de la Guatlla we embed glass-fibre mesh in mortar, overlapping the strips and extending well beyond the crack on both sides. At window and door corners we add diagonal reinforcement.
With over 20 years of experience we can tell a crack that just needs sealing from one that needs a different approach, and explain it in a written quote. Our work also covers areas close by: Eixample, Les Corts and Ciutat Vella.

Frequently asked questions
01Exterior render crack repair in Sants-Montjuïc: which areas do you cover?
We work in Sants-Montjuïc in areas such as Sants, Sants - Badal, Hostafrancs, La Bordeta, La Font de la Guatlla, El Poble-sec, La Marina de Port and La Marina del Prat Vermell, and also nearby: Eixample, Les Corts and Ciutat Vella.
02Are 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.
03Why 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.
04Will 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.
