“tuckpointing, in building construction, technique of finishing masonry joints with a fine, pointed ridge of mortar, for decorative purposes, instead of the usual slightly convex finish in ordinary masonwork. The term is sometimes used for pointing as in masonry repair” http://www.britannica.com/EBchecked/topic/608406/tuckpointing
Rather, it is the type of masonry restoration endeavor, as defined by tuckpoint specialists in the United States, where loose and crumbling mortar is replaced with a new mixture of the same color and texture as the original. The usual purpose for replacing the defective mortar is not only for cosmetic purposes, but to provide structural strength to the chimney and to protect the underlying surfaces from the elements.
Although porch repairs are the most commonly requested repair due to the harsh effects of weather, chimneys are a close second. The basic home structure is insulated and not quite as susceptible to the freeze-thaw cycles of Mother Nature. Hairline cracks eventually turn into larger ones with water being able to leak inside. Subsequent expansion and contraction cycles can threaten the entire chimney.
