Tar-like creosote lines the flue from slow-burning fires - the leading cause of chimney fires.
Have the chimney swept and inspected before the next burn; creosote grade 2-3 needs professional removal.
Typical fix cost in Boise: $150-$450. Do not attempt work on live systems - get a licensed specialist on it.

Regular maintenance catches most of these early - see the maintenance checklist in the emergency guide.
