The cowls on Narre Warren's wood heater flues have been up there as long as the estates. FreshDuct replaces the seized and rusted ones, fits guards where birds have moved in, and cures the downdraught that shows up on windy nights.
Cowl squeaking on the roof or not turning at all? It has done its years — replacement is straightforward and photographed.
The cowl on a Narre Warren flue was chosen by whoever fitted the heater when the estate was built, and it has been up there ever since. On a well-established estate that means years of sun, rain and wind on a light-gauge fitting held by a few screws. The rotating ones seize, the fixed ones rust at the base, and the mesh on any spark arrestor corrodes through, all without anyone on the ground noticing.
Once a cowl stops doing its job, the flue starts to show it. A seized rotating cowl no longer turns away from the wind, so the heater smokes back on gusty nights. A rusted cowl lets rain straight down the pipe into the firebox. And a cowl with a gap in its mesh is an open invitation to the birds that nest in warm flues over summer and are discovered by the first fire of autumn.
We measure the flue on the roof, match a replacement cowl to the flue system and the heater, and fit it with fixings that will outlast the old ones. Where downdraught is the complaint, an anti-downdraught cowl goes on and the draw is tested with the fire lit. Nests are cleared before the guard goes on. A photo of the finished terminal comes with the job.
Replacement cowls, anti-downdraught cowls and bird guards for Narre Warren wood heater flues that have outlived their original terminal.
The original cowl on an estate heater was never meant to last as long as the house. We replace seized, rusted and rattling cowls with terminals matched to the flue, fixed properly and sealed, and photograph them from the roof.
A cowl with corroded mesh or a lifted cap is where birds nest through a Narre Warren summer, and the first fire of the year finds them. We clear the flue, fit a guarded cowl and check the draw before we leave.
When a heater that used to draw fine starts pushing smoke into the room on gusty nights, the cowl has usually seized. An anti-downdraught cowl that still turns is the fix, and we test it with the fire going.
Real photos from Melbourne jobs — not stock, not staged.




A twin-wall flue takes a terminal made for its diameter and system, not the nearest thing off a shelf. We measure the pipe and the existing fitting on the roof and match the replacement to it.
Fitting is from the roof with harness work where the pitch calls for it, the draw is checked with the heater lit, and you get the photo without the ladder.

Yes, if it is the type meant to turn. A seized rotating cowl no longer shields the flue from wind, so the heater will start smoking back on gusty nights. We replace it with a matched terminal and test the draw with the fire lit.
Just the cowl, in most cases. The terminal is a separate part that fits the top section of the flue. We measure the pipe, match a replacement and fit it from the roof. If the top section itself has rusted, we say so and quote that separately.
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.
