Small cracks can matter in exposed positions

Hairline shrinkage is not automatically serious, but cracks around window corners, parapets and changes in substrate deserve attention because they repeatedly receive run-off.

Check the lower edge

Render that runs down into the ground or across a DPC can bridge the damp-proof course. The resulting low-level damp may then be blamed on DPC failure.

Hollow render changes the repair

Large debonded areas can hold water behind the finish. Filling the visible crack alone may not deal with a widespread loss of adhesion.
