The mortar between the bricks on your chimney can begin to crack and crumble over time because of the constant exposure to the outside elements. Damaged mortar can open areas between the bricks and allow moisture to invade the chimney, leading to the possibility of chimney collapse and costly repairs. You can and should remove the damaged, old and loose mortar from the joints between the bricks and replace it with new mortar or masonry repair caulk in a procedure known as re-pointing.
wiki definition of repointing:
Repointing is the process of renewing the pointing (the external part of mortar joints) in masonry construction. Over time, weathering and decay cause voids in the joints between masonry units (usually bricks), allowing the undesirable entrance of water. Water entering through these voids can cause significant damage through frost weathering and from salt dissolution and deposition.
