Cracked and deteriorated brick or mortar, which are usually in the back wall, water infiltration, and not properly built firebox dimensions, which is a source of smoking into the room, these are common problems found within a fireplace. These cracks are found by the National Fire Protection Association (NFPA) as fire hazards, because as the smoke carries waste particles from the fire and deposits these particles on the walls, inside and behind the cracks, and the oily substance, known as creosote, from these particles can re-ignite from sparks rising in the chimney; therefore, these walls should be free from creosote build-up. Cracks can be repaired by carefully chiseling out the cracked areas and covering them with Portland cement or fire-clay, but should never be surface-coated or smeared, because this will not bond well with the dirty, smoky surface.
When water infiltrates the chimney, it mixes with the deposited particles on the chimney walls, like creosote and other deposits, thus the resulting mixture is an acidic compound which prematurely corrodes the damper and causes deterioration of the brick and mortar. Further, the entrance of water may infiltrate cracks in the chimney crown, the shell itself or may cause faulty flashing where the chimney meets the roof, and all these may extend its damages to the ceiling and flooring materials of the house, which are adjacent to the fireplace.
There is a build-up of smoke in the living area derived from improper dimensions of the chimneys, and the reason for the improper dimensions is found in two common design flaws: the chimneys are too short to prevent downdrafts and the areas between the lintel and throat of the chimney are not tall enough to allow smoke to roll before entering the smoke shelf.
Chimney bricks are hard-fired materials that can last over 100 years, but when rain soaks into the brick, then freezes and expands due to harsh weather elements, the thin layers of the brick slowly begin to fall off and land at the base of the chimney. Furthermore, other forms of deterioration may occur to mortar joints, which may get weaken or develop premature voids, however, all these results may actually depend on the type of mortar used and the methods at http://brickexpertsdfw.net/masonry-services/masonry-repair/ used during the original construction.
