Caution
The mortar joints have gone sandy and you can rake them out with a key or a fingernail.
The front face of bricks is flaking, blowing off or crumbling away, leaving the softer inside exposed.
High risk

Low risk
A white, dusty or crystalline bloom has appeared on the face of the bricks, often on a new wall.
Hard grey pointing stands proud of the brickwork and the brick faces around it have started to crumble.
The vents low down in an external wall are blocked with soil, paint, insulation or a new patio.

The brickwork above the roof line has lost its mortar, shed brick faces, or started to lean to one side.
The lowest courses of brick are eroded, crumbling or missing their faces while the wall above is sound.
