Repointing your brick or rebuilding the wall
If the bricks are sound and it's the mortar that's failing, repointing is almost always the better choice, because it keeps your original wall and costs far less than tearing it down. Rebuilding a section makes sense when bricks are cracked through, badly flaked or the wall has started to lean. A leaning wall that's holding back soil usually needs more than brick repair, and that's where retaining wall construction comes in.
