Cracks in walls

Hairline or bigger cracks in plaster, inside or outside.

Why it happens

  • Plaster shrinking as it dries
  • Heat and cold making the wall move
  • Joints between brick and concrete

Signs to look for

  • Thin lines in the paint
  • Cracks that come back after painting
  • Water entering through cracks outside
