Common Chimney Problems
Understanding common chimney problems helps you identify issues early, before they become expensive repairs. Here are the most frequent chimney issues we encounter.
Creosote Buildup
The #1 cause of chimney fires. Creosote is a flammable tar-like substance that accumulates in your flue from burning wood.
Cracked Chimney Crown
The crown protects the top of your chimney. Cracks allow water to enter, causing freeze-thaw damage and structural deterioration.
Damaged Flashing
Flashing seals the gap between your chimney and roof. When it fails, water leaks cause damage to roofing, framing, and interior walls.
Deteriorating Mortar Joints
Over time, mortar erodes from weather exposure. Gaps allow water infiltration that accelerates structural damage.
Blocked Flue
Animal nests, debris, and creosote can block your flue, causing dangerous carbon monoxide buildup and smoke backflow.
Missing or Damaged Cap
Without a cap, rain, animals, and debris enter freely. This leads to moisture damage, blockages, and increased deterioration.
