Understanding Leaking Chimneys
What is a Chimney Leak?
A chimney leak is any water intrusion that enters the chimney or its surrounding structure. Left untreated, leaks can damage bricks, mortar, ceilings, and even your home’s framing.
Common causes include cracked crowns, failed flashing, missing caps, and deteriorated masonry.
Causes of Chimney Leaks
What Causes Chimney Leaks?
Chimney leaks occur when water infiltrates the chimney structure, leading to potential damage. Common causes include:
Cracked Chimney Crown - Hairline fractures or larger cracks in the concrete crown allow water to enter and expand over time.
Damaged Flashing - Faulty or rusted flashing where your chimney meets the roof is one of the most common leak sources.
Missing or Faulty Chimney Cap - Without a cap, rainwater enters directly—and may bring animals and debris with it.
Eroded Mortar Joints - Freeze-thaw cycles in Cincinnati winters break down mortar over time, letting moisture seep in.
Spot the Signs Early
Signs of a Leaking Chimney
Catch the leak early before major repairs are needed. Look for:
Efflorescence – White, chalky stains on chimney brick
Spalling – Flaking or breaking bricks
Cracked Mortar – Gaps forming between bricks
Ceiling or Wall Stains – Discoloration near fireplace
Musty Smells – Especially after rain
Rust – On the damper, firebox, or nearby metal
If you notice any of these signs, it’s important to get your chimney inspected for leaks immediately.
