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. 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. A chimney that is infiltrated with water can result into water mixing with the deposited particles on the chimney walls, like creosote and other deposits, and the resulting mixture is an acidic compound which prematurely corrodes the damper and causes deterioration of the brick and mortar. Water infiltration into the chimney may also reach the chimney crown and the shell itself or may cause faulty flashing where the chimney meets the roof, and all these can further cause damages to the interior ceiling and flooring materials of the house, which are near the fireplace.
A Brief History of Repairs
There are two common design flaws have been detected, the reason for the improper dimensions found in chimneys, 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, and because of this, there is a build-up of smoke in the living area.
Getting Creative With Repairs Advice
The effects of rain and harsh weather conditions may cause deterioration on the chimney bricks, which are supposed to last more than 100 years because they have been hard-fired, and the effect is such that 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. 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 used during the original construction.
