Wall Crack Repair: Cosmetic Crack or Repair Concern?

Cracks should be assessed in context

Not every wall crack requires the same repair. Location, width, direction, movement and signs of dampness all influence the recommendation.

Moisture changes the repair decision

A crack that also allows water ingress may need leak treatment before cosmetic reinstatement. Covering it too early can hide the symptom while the cause remains.

Practical next step

Document the crack and monitor whether it changes after rain, nearby works or repeated wetting.
