A dirty chimney means creosote buildup, which is flammable and can cause a chimney fire if not removed. The correct action is to clean the chimney to remove that buildup, reduce the fire risk, and restore proper draft for safe venting.

Pulling a liner is a major repair done when the liner itself is damaged or deteriorated, not a fix for creosote. A damper controls airflow but doesn’t remove dirt or creosote. Sealing the chimney would block venting and create dangerous problems. If the liner is damaged, that would be addressed separately from cleaning.
