Pointing is the process of replacing deteriorated mortar in the joints of a masonry wall with new mortar. Obvious signs of deterioration signal the need for pointing. These include: disintegrating mortar, cracks in mortar joints, loose bricks or stones, damp walls, or damaged plasterwork.
It is critical that craftsmen specializing in brick and stone pointing are hired to execute the work. This ensures the visual and physical integrity of the masonry. An improperly done job will detract from the appearance of the structure and cause physical damage to the masonry itself.
