Cracked Mortar: Inspect the mortar joints between bricks. Cracks or gaps indicate water infiltration and weakening of the structure.
Spalling Bricks: If you notice bricks chipping flaking or breaking apart it’s a sign of deterioration due to weather exposure.
Efflorescence: White powdery deposits on the chimney surface suggest water penetration. It’s often caused by salt leaching from the bricks.
