Signs your chimney needs cleaning

The short answer

Your chimney needs cleaning if the fire is hard to light or smoulders and won't draw, if soot or black flakes fall into the firebox when it's cold, or if there is heavy, oily staining around the opening. After more than a year of regular use, it is due anyway.

Key points

  • A fire that smoulders and won't draw can mean the flue is restricted by creosote or debris.
  • Soot or black flakes falling into a cold firebox is another sign.
  • Heavy, oily staining around the opening means build-up is coming faster than it should.
  • More than a year of regular use means a sweep is due anyway.
  • A FreshDuct fireplace clean starts from $169, with no call-out fee.

Fire hard to light, or smoke drifting into the room? FreshDuct explains the signs your chimney needs a clean. A fire that smoulders and won't draw can mean the flue is restricted by creosote or debris. Soot or black flakes falling into the firebox when it's cold is another sign. Heavy, oily staining around the opening means build-up is coming faster than it should. And if it's been more than a year of regular use, it's due anyway.
