Leaking chimney flashing on older brick chimneys
Why it happens here
Brick chimneys in Janes Village have often been repointed without new flashing, leaving a gap at the mortar joint. Water gets behind the counter flashing and runs down the chimney into the attic. The freeze-thaw cycle in Altadena makes the gap worse each year.
Our approach
We cut a proper reglet into the brick, set new counter flashing, and seal the joint with polyurethane that stays flexible. This is a permanent repair, not a sealant patch that fails in a year.
