Cracked bricks or cracked mortar joints
A crack through a brick and a crack following the joints are different observations. Record the pattern before deciding that either one needs only a surface patch.
Show the crack in context
Take a wide photograph of the wall and a closer image from safe ground. Note nearby windows, corners and previous repairs. Describe when you first noticed it and whether its appearance has changed. Do not remove material to investigate the depth yourself.
Define the next step
Ask what assessment is needed before choosing between repointing and brick replacement. The visible pattern is a starting point, not a diagnosis.
