​There are many potential causes of a smoking fireplace. If your chimney persistently smokes, there could be many things affecting the draft. First, make sure that the damper is fully open. If the damper is fully open, then make sure that nothing is blocking your chimney flue.

  • The construction of the fireplace and chimney could also be causing issues. If the opening of the fireplace and the size of the flue are not proper ratios, the smoke won't be correctly directed out of the home.
  • The wood that you are burning can also create a smoking fireplace. Burning unseasoned or green wood can produce a very smoky fire. Half of the weight of a piece of freshly cut wood is water. To properly season wood, it can take nine months or longer.
  • Chimneys should be inspected annually to prevent creosote buildup or other potential issues.
