Key takeaways
- Look at the crown, mortar joints and flashing from the ground
- White stains and flaking brick mean water is getting in
- Rust at the damper and stains on nearby walls are warnings
- Repairs before the freeze save damage
A chimney stands in the weather on every side. A few minutes of looking each year catches problems early.
From the ground
With binoculars, look for cracked crown cement, missing mortar, loose or flaking brick and any lean.
On the roof line
Check the flashing where the chimney meets the roof. Gaps and rust are common leak points.
Inside
Water stains on the ceiling or wall near the chimney, a musty smell, or rust on the damper all point to water entry.
Acting early
A crown repair or a bit of repointing is a small job. Left alone, water works into the stack and the cost goes up.
