Brick repair or rebuilding the wall
Most walls I look at need repair, not replacement. If the bricks are sound and only the joints have worn, repointing puts the wall back in good shape and keeps the brick you already have. Rebuilding starts to make sense when a section has a lot of cracked bricks, has shifted, or keeps cracking in the same spot. At that point I'll also tell you if the cause needs an engineer before any mason touches it.
