An older masonry chimney in earthquake country?
- A pre-war brick chimney, especially unreinforced
- Hairline cracks at the roofline or the chimney's shoulder
- Any noticeable quake since the last time someone looked
Why it happens in California: California's defining chimney fact is seismic: unreinforced masonry chimneys are the classic earthquake casualty, and every notable quake since Northridge has brought a wave of cracked and shifted stacks. A pre-war California chimney deserves a seismic-minded look, and after any quake you felt, another one — before the next fire, not after.
What fixes it, and what it costs
A seismic-minded inspection reads the specific tells: separation at the roofline, shear cracking, hasty past rebuilds above the shoulder. The camera checks what shaking did inside the flue, where cracked tiles hide. After any quake you felt, the look comes before the next fire. Where the stack needs it, options run from repair and bracing to rebuilding above the roofline in lighter construction.
