A fireplace that has cracked and deteriorated brick or mortar, which are usually in the back wall, water infiltration, and is structured in an improper dimensions, which is a source of smoking into the room, are the usual problems found in fireplaces. 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.  The process of repairing cracks is to chisel out the cracked areas and covering them with either Portland cement or fire-clay; however, one should never coat or smear the surface of the newly-covered cracked areas, as they will not bond well with the dirty, smoky surface.

 

Water infiltrating a chimney can cause serious problems, such that as water enters and mixes with the deposited particles on the chimney walls, like creosote and other deposits, 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.

 

Improper dimensions of chimneys can cause a build-up of smoke into the living area and two common design flaws have been detected, the reason for the improper dimensions, which are: 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 at http://brickexpertsdfw.net/ 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.  In addition to the brick deterioration, mortar joints can also deteriorate or develop premature voids, but all these results may actually depend on the type of mortar used and the methods at http://brickexpertsdfw.net/about-us/ used during the original construction.
