On the bush fringe of Lilydale, the cap on a wood-heater flue is a fire-safety fitting first and a weather fitting second. FreshDuct fits and clears spark arrestors, replaces tired cowls on heater flues and open fires, and sorts downdraught on tree-sheltered blocks.
Spark arrestor caked in creosote? It is blocking the draw and no longer stopping embers — we clear or replace it.
Lilydale sits where the suburbs meet the Yarra Valley and the foothills, and a lot of homes here back onto bush or sit under big eucalypts. Every wood heater on those blocks should have a spark-arrestor cap, but an arrestor is only useful if the mesh is clear and the cap is still fixed and sound. Over a hard winter the mesh loads with creosote and leaf, the draw drops, and the heater starts to smoke.
We fit arrestor caps sized to the flue, with mesh fine enough to hold embers but open enough to draw, and we clear or replace the mesh at each sweep so the heater keeps breathing. On open fireplaces in the older township homes, the same logic applies with a brick chimney: a cap with an arrestor mesh and bird guard keeps embers in and possums, birds and gum litter out of a flue that would otherwise collect all three.
Downdraught is common on the sloping, tree-sheltered blocks around Lilydale, where wind rolls over a stand of trees or a rise and comes down the flue instead of drawing up it. A rotating or anti-downdraught cowl on the heater flue usually solves it, and because the wrong cowl can make a heater worse, we test the draw with the fire lit before we sign it off.

On a Lilydale block with bush or gums close by, an open flue top can throw a live ember onto dry litter. A spark-arrestor cap holds the embers in the flue, and we keep its mesh clear so it does not choke the heater.
A heater that has done ten Lilydale winters often has a cowl rusted at the seams and an arrestor mesh burnt thin. We replace the cowl with one matched to the flue diameter, with new mesh and fixings that hold, rather than clearing a terminal that is past it.
Wind rolling over trees or a rise pushes down a Lilydale heater flue and fills the room with smoke on gusty nights. The right cowl fixes it, the wrong one worsens it, so we test the draw with the fire lit after fitting.

Too fine a mesh and the heater smokes; too coarse and embers get through. We size the arrestor cap to the flue and the heater, fit it from the roof, and check the draw so you get the fire protection without a heater that sulks.
A roof photo of the fitted arrestor comes with the job, and if we are back for the winter sweep the mesh gets cleared as part of it rather than as an extra.

No. The mesh is choked with creosote, which is why the draw has dropped, and removing it leaves the flue open to throw embers toward the trees. We clear the mesh, or replace the cap if it has rusted, and the draw comes back with the protection intact.
Both. An open fire sends embers up a brick flue just as a heater sends them up a steel one, and with trees close by the risk is the same. We fit a cap with arrestor mesh and a bird guard to the brick chimney and clear it at each sweep.
An open flue lets rain, leaves and birds straight in. A cap keeps the flue dry, keeps nests out and, on a wood heater, a spark arrestor stops embers leaving the flue.
Usually a downdraught — wind pushing back down the flue. An anti-downdraught cowl is the normal fix; we confirm the draw with a test before and after.
Yes. If we are on the roof for a sweep and the flue needs a cap, we can quote it on the spot and fit it the same visit where we have the right size.
