Loose or missing mortar can occur due to weathering, age, or moisture exposure. Over time, mortar joints can weaken, allowing water to infiltrate, which can lead to further damage and compromise the chimney's stability. A faulty liner or issues from the inside of the chimney can also contribute to loose or missing mortar. Problems like gas leaks, moisture buildup, and white staining (efflorescence) are signs of internal chimney issues that can also cause mortar to deteriorate. These internal problems, combined with external weathering, can accelerate the breakdown of the mortar, leading to compromised structural integrity. Regular inspections can help identify these issues early and prevent costly repairs.
Cracked bricks are often visible to the naked eye, with broken pieces on the chimney’s exterior. If you notice any cracks, it’s essential to have a professional inspect the chimney to prevent further damage and ensure safety.
