Tuckpointing versus replacing your brick
If the bricks are solid and only the mortar is worn, tuckpointing is the right call, because you keep the original brick and just renew the joints. When the bricks themselves are cracked, flaking or loose, new mortar won't fix them, and those spots need brick repair first. A wall that's leaning or split clear through is a bigger conversation, and I'll tell you so plainly rather than sell you a pointing job that won't hold.
