I have brick steps that lead up to the front porch and the mortar is crack in a number of places. It looks like a previous owner tried to use caulk to patch it up but I don't think it is working due to the moist cinder block wall in the basement below.
I have seen many articles on re-pointing a brick wall and was wondering if any additional precautions need to be taken into account when re-pointing brick steps. I would like to take out the old caulk and get a clean look about it.

Any ideas/suggestions?
