When brick pointing is enough, and when it isn't
If the bricks are sound and only the joints have worn, pointing is the right fix, and rebuilding a good wall would spend your money for nothing. Bricks that are cracked through or flaking need brick repair before we point around them. Cracks that step up the wall or keep opening can mean the footing is moving. Then I'll tell you plainly it's a foundation repair question, sometimes for an engineer, before pointing makes sense.
