Cracked Chimney Crown: What To Do

A cracked crown lets Portland rain into the masonry. Here is what it means, how urgent it is, and how we fix it.

Why Crowns Crack in Portland

The crown is the sloped concrete top of a masonry chimney. Constant rain, poor original pours, and freeze-thaw cycles cause cracks. Once water enters, brick and mortar deteriorate from the top down.

Repair vs Rebuild

  • Small hairline cracks — sometimes sealable if the crown is otherwise sound
  • Wide cracks, crumbling edges, or ponding water — usually a full crown rebuild

What We Recommend After Crown Work

Confirm the cap is solid, check flashing, and consider waterproofing so the restored top stays dry. Related reading: chimney leaks in Portland.

Not in Portland. Small cracks grow quickly with rain and freeze-thaw cycles.

Most crown rebuilds are completed in about a day, plus cure time before heavy weather exposure.
