Every wood fire leaves soot behind, and slow or smoky burns add a harder, tar-like layer called creosote. Over a season of burning, those layers narrow the flue and change the way your fireplace behaves.
What build-up does to your fire
A narrowed flue means a weaker draught. Fires become harder to light, smoke lingers, and you burn through more wood for less heat. In the worst case, heavy creosote deposits become a fire risk in their own right.
What a sweep does about it
A sweep brushes the full length of the flue, removing soot and creosote and restoring the clear passage your fire was designed for. The result is a fire that lights easily, draws cleanly, and heats the way it should.
