On a Greensborough block the cowl on a wood-heater flue is doing three jobs at once: keeping bark out, keeping rain out and keeping embers in. FreshDuct fits spark-arrestor cowls and guards sized to the flue and tests the draw with the heater lit.
Wood heater under gum trees in Greensborough? A spark arrestor is not optional up here — we fit them as standard.
The terminal on top of a Greensborough heater flue lives a hard life. It sits under a canopy that drops bark, leaf and gum nuts on it all year, it takes the rain that blows in over the river, and every winter night it is the last thing hot embers pass on their way out. A plain open cowl does nothing about any of that. The cowls we fit here are chosen for the block, not just the flue diameter.
The first priority on a treed block is the spark arrestor. A mesh cowl stops embers leaving the flue and landing on dry litter in the gutters or on the ground below, and it stops the same litter falling in. The mesh needs to be the right gauge: too fine and it chokes with soot in a season and the heater starts smoking back; too coarse and it stops nothing. We size it to the heater and tell you when it will need clearing.
Downdraught is the other Greensborough complaint. Homes on the slopes around the river have terminals that sit below a ridge, a taller tree line or the neighbour’s roof, and wind rolling over those pushes smoke back down the pipe. An anti-downdraught cowl, or in some cases a flue extension to lift the terminal into clean air, sorts it. We fit the cowl, light the heater and watch the draw before calling it done.
Spark-arrestor cowls, rain caps, bird guards and anti-downdraught cowls for wood-heater flues and brick stacks on Greensborough’s treed blocks, fitted from the roof and tested.
A heater flue among gum trees needs a spark-arrestor cowl, sized so it stops embers without choking on soot. We fit the mesh gauge to suit the heater and show you how to tell when it needs clearing.
An open terminal under a canopy fills with litter and the heater stops drawing. A guarded cowl keeps it out; we clear what is already in the flue before fitting so the guard is not capping a blockage.
Flues on the lower side of a Greensborough slope sit in turbulence off the ridge and the trees. An anti-downdraught cowl or a short flue extension puts the terminal in clean air, and we test the draw with the heater lit.
Real photos from Melbourne jobs — not stock, not staged.
The cowl is chosen for the block, fixed and sealed to the flue from the roof, and then the heater is lit. We watch the draw at the door and the smoke at the terminal, because a cowl that looks right and draws badly has not fixed anything.
You get a photo of the finished terminal from the roof and a note on the mesh gauge and when to have it cleared. If the terminal needed a flue extension to clear the ridge, the photo shows the new height as well.

Usually. A terminal sitting below a ridge, tall trees or a taller roof gets wind pushed down it. An anti-downdraught cowl is the first fix; if the terminal is too low, a flue extension lifts it into clean air. We fit it and test with the heater lit.
On a block under gum trees, yes. Embers leaving an open flue land on dry bark in gutters and on the ground, and the same litter falls into an unguarded flue. A mesh cowl sized to the heater does both jobs; it needs clearing when it starts to soot up.
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.
