Chimney Caps & Cowls in Mount Waverley

Mount Waverley homes have been extended and built up more than most, and a flue that once cleared the roof can end up in the lee of a new second storey. FreshDuct raises terminals, fits the right cowls and replaces rusted ones, then tests the draw.

Fireplace started smoking after the extension in Mount Waverley? The terminal is probably now too low for the new roof.

A second storey beside an old flue turns a steady draught into a downdraught, because wind spilling off the new roof lands on the terminal. The heater has not changed; the roofline has, and the cap has to catch up.
Terminals and Rooflines

When a Mount Waverley extension makes the fireplace smoke

The commonest terminal problem we see in Mount Waverley has nothing to do with the terminal wearing out. A post-war home gets a second storey or a big rear extension, the flue that used to stand clear now sits below or beside a taller roof, and wind tumbling off that roof presses down on the cowl. The heater that drew perfectly for forty years starts filling the room with smoke, and the owner assumes something has broken inside the flue.

So before we sell a cowl we measure. The flue terminal is checked against the roof as it stands today, not as it was built, and if it no longer clears the new ridge by enough, the fix is extra flue height with a properly braced extension and the right cowl on top of it. Where the height is fine and the problem is turbulence, an anti-downdraught cowl on its own usually does the job, and we light the heater to prove it.

The ordinary wear is here too. Cowls on heaters fitted decades ago have rusted through or worked loose, and an original brick stack that still serves an open fire often has no cap at all, so rain and leaves from the garden go straight down. We replace the rusted cowl with one sized to the flue, cap the open stack with a bird guard, and photograph both from the roof.

Local Know-How

Chimney Caps & Cowls in Mount Waverley: what is different here

Measured against today's roof

A flue that cleared the original Mount Waverley roofline may be well short of a new second storey. We measure the terminal against the roof as it is now and, where it falls short, extend the flue and brace it before fitting the cowl.

Rusted-through cowls

A heater cowl fitted decades ago has had a long life on a Mount Waverley roof and often has holes in it or is barely attached. We replace it with one sized to the flue, fixed properly, and photograph it so you can see it is sound.

Sealed-up houses

Extended and renovated Mount Waverley homes are far more airtight than they were built, and a heater starved of air smokes under any cowl. We check the room has an air supply before blaming the terminal, and say so if that is the real fix.

Three reasons a Mount Waverley fire smokes, one visit

Terminal too low for the new roof, wrong cowl for the turbulence, or not enough air getting into a sealed-up room: those three cover most of the smoking heaters we see in Mount Waverley, and each needs a different fix.

We work out which it is on the day, quote that, fit it from the roof and then light the heater and watch the draw before we go, with a photo of the terminal for your records.

FAQs

Chimney Caps & Cowls in Mount Waverley — questions answered

We added a second storey to our Mount Waverley house and now the heater smokes. Will a cowl fix it?

Sometimes, but often the flue is now simply too low for the new roof, and a cowl alone will not overcome that. We measure the terminal against the roof as it stands, extend and brace the flue if it needs height, fit the right cowl on top and test the draw with the heater lit.

The cowl on our Mount Waverley heater flue rattles in the wind. Is that dangerous?

It means the fixings or the cowl itself have rusted, and the next storm may take it off, leaving the flue open to rain. We replace it with a cowl sized to the flue and fix it properly, which is a small job while it is still on the roof.

Do I really need a chimney cap?

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.

Why does my fireplace smoke when it is windy?

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.

Can you fit a cap while sweeping?

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.
