An open 1960s flue full of nest, or a new cowl that has blocked or worked loose: Glen Waverley roofs show both. FreshDuct caps the mid-century chimneys, sorts out the cowls on the rebuilds, and photographs every one from the roof.
Birds in the chimney every spring? A cap with a guard ends it, and it fits during a sweep.
Many of the original Glen Waverley chimneys were finished with nothing more than an open top, and after decades that is where the trouble starts. Birds find the sheltered flue in spring and fill it with twigs, and a season of rain on top packs the lot into a plug. The first cold night the fireplace is lit, smoke rolls back into the lounge, and the owner discovers that the chimney has been a nest box since September.
A new cowl brings its own faults. The inbuilt heaters in the rebuilds came with one, and modern cowls either clog with creosote where the flue gases cool or work loose on the flue and start to rattle and let rain in. A blocked cowl is why a new heater smokes back into a new living room, and it is a job we can often sort out during a sweep once we have identified the flue system it sits on.
An open mid-century flue gets a rain cap with a bird guard sized on the roof, so nests and rain are both kept out from the same fitting. A rebuild’s wood heater gets a cowl that belongs to its flue system rather than one that roughly fits, or a spark arrestor if the block backs onto trees. Gas fireplace terminals are cleared and checked, with the appliance itself left to the licensed gas specialists we arrange, and every terminal is draw-tested and photographed.
Rain caps and bird guards for open mid-century flues, matched cowls and spark arrestors for rebuild heaters, and gas terminals kept clear, across Glen Waverley.
An uncapped 1960s chimney in Glen Waverley is a ready-made nest box, and a nest is a blockage and a fire risk in one. A cap with a bird guard ends the annual clear-out, and we clear the flue before it goes on.
Modern cowls on rebuild heaters catch creosote where the flue gases cool, and a clogged one chokes the fire. We clear it, or replace it with a cowl that suits the flue system, and check the draw with the heater running.
A twin-wall flue on a rebuild takes a cowl from its own system, and a generic one perches loose and leaks. We identify the flue before ordering the cowl, so the part that goes on fits and locks the way it was designed to.

What a Glen Waverley flue needs on top depends on what it is: brick pot or twin-wall steel, open fire or inbuilt heater, trees over the roof or not. We decide on the roof with the flue in front of us, not from a catalogue at the kitchen table.
The fitting is sealed, the draw is tested with the fire going where we can, and the photo from the roof shows the finished cap or cowl seated square on the flue.

A cap with a bird guard, sized to the flue and fixed properly. We clear the old nest and sweep the flue first, because capping a blocked chimney just locks the blockage in, then fit the cap and photograph it. After that the birds find somewhere else.
Very likely. A modern cowl collects creosote where the flue gases cool at the top, and once it clogs the whole flue draws poorly and the glass blackens. We clear or replace the cowl with one matched to the flue system, sweep the flue below it, and test the draw with the heater running.
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.
