If you see soot or creosote accumulations, it is possible to start another fire. You may need fireplace repairs if your bricks or mortar are cracked or in poor condition. Cracked and deteriorating bricks, water intrusion, and insufficient dimensions for your firebox are the most frequent issues encountered inside the firebox, often leading to smoke being emitted into the space.
The cracks that appear in the wall or internal chimney lining are considered fire hazards by the NFPA. A fire’s waste is carried by smoke, which eventually causes deposits on the walls, within gaps as well as behind the other items. Fires that ignite in the bricks may ignite the sticky substance called creosote. Therefore, it’s crucial to stop the build-up of creosote in these walls, and also repair any cracks when they begin to appear.
Cracked mortar may be fixed by gently chiseling broken areas before tucking them with portland cement or fireclay. It is not recommended to coat the surfaces or spread out since this will stop the coating from sticking to the grubby, smokey surface. An expert in fireplace repairs is able to help with the task.
