A Collingwood terrace stack can carry four or five pots, and every open one is a way in for rain, birds and downdraught. FreshDuct caps the flues in use, vents the ones that are not, and fits cowls that stop a tall terrace flue smoking on a windy night.
Pigeons in the terrace flue? A bird guard on the pot ends it — and we clear what they left first.
Look along a Collingwood terrace roofline and you will see stacks with a row of terracotta pots, some in use and most not. Each open pot lets rain straight into a flue that runs two storeys down an unlined party wall, and the disused ones are where pigeons and starlings nest. The result is damp in the chimney breast below and a blocked flue above the one fireplace that is still lit.
We treat each pot on its merits. A flue in use gets a cap with a bird guard that keeps rain and nests out while letting smoke leave, fitted to the pot without cutting it. A flue that is out of use gets a vented cap that keeps the weather out but lets the brick breathe, because sealing a Victorian flue airtight traps damp in the wall. The pots stay, and the stack keeps its heritage profile from the street.
Downdraught is the other terrace complaint. A tall flue beside a taller conversion, or one that opens below the ridge of the neighbouring roof, gets wind pushed down it and the fire smokes on gusty nights. An anti-downdraught cowl on the pot usually settles it, and we test the draw with the cowl on before we call it fixed.
Pot caps, bird guards, vented caps for disused flues and anti-downdraught cowls for Collingwood terraces and conversions, fitted from the roof and photographed.
Terrace stacks have more open pots than working fireplaces, and the idle ones fill with nests and debris that end up behind the bricked-up fireplace below. We guard every pot, not just the one in use, and clear what has already gone down.
A heritage terrace stack loses its character the moment the pots come off. Our caps and cowls clamp to the pot or sit inside it, so the roofline reads as it always has from the street.
Where a two-storey terrace sits beside a converted warehouse, wind spilling off the taller wall drives down the shorter flue. An anti-downdraught cowl on the affected pot is the fix, confirmed with a draw test rather than assumed.
Real photos from Melbourne jobs — not stock, not staged.
Before fitting anything we work out which pot serves which fireplace, because on a terrace stack that is rarely obvious from the roof. A smoke test from the hearth settles it, and each pot then gets the cap that suits its job.
Terrace stacks are tall, so the work is roped where it needs to be, and you get a photo of every capped pot so you can see the stack is finished without borrowing a ladder.

Yes. We clear the nest and debris from the flue, sweep it, then fit a bird guard to the pot so the flue stays open for smoke but closed to birds. On a terrace stack we usually guard the disused pots too, since that is where the nesting starts.
Not airtight. A Victorian flue in an unlined party wall needs to breathe or damp collects in the brick. A vented cap keeps rain and birds out while letting air move, which is the right answer for a disused terrace flue.
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.
