Too much moisture can slowly weaken mortar. Dark spots and damp areas may appear on the wall. You may also see a white powder on the brick. This is called efflorescence. It can appear when water carries salts through the masonry. Brick Repointing can repair mortar joints damaged by water. The source of the moisture should also be fixed. If it is not, the damage may come back.
