The cap on a Moorabbin chimney is where the sea breeze does its first damage, and plenty of post-war pots in the suburb have none at all. FreshDuct fits corrosion-resistant caps, heater cowls and guards from the roof and photographs them in place.
Moorabbin pot uncapped since the house was built? Sixty winters of rain have gone down that flue.
Many Moorabbin chimneys have been open to the sky since the 1950s. Post-war builders finished the stack with a terracotta pot or a flat mortar top and no cap, because the open fire below kept the flue warm and dry. Now there is a wood heater in that fireplace, the flue is cold for months, and every shower runs down the brick onto a smoke shelf coated in creosote. The mix is corrosive, which is why these stacks dust mortar into the grate.
The cap has to survive the setting. Moorabbin is far enough from the beach that people forget the sea air, but it reaches the roofline and a galvanised cap rusts at its fixings within a few years. We fit stainless or coated caps with corrosion-resistant fasteners, sized to the pot or the flat top, so the cap outlasts the reason it was fitted.
Where the heater has its own flue kit rising through the old pot, the terminal on top needs a cowl that matches the heater, and it is often missing or seized. A rusted cowl that no longer turns causes smoke back into the room on a southerly. We replace it with a fixed anti-downdraught cowl sized to the kit, and on the older open fireplaces still in use we fit a rain cap with a bird guard, then test the draw with a fire going.
Corrosion-resistant rain caps, heater-flue cowls and bird guards for Moorabbin’s post-war stacks, sized on the roof, fitted and photographed.
Post-war Moorabbin stacks were often built without a cap. Rain has been running down the brick since, and now lands on creosote above a heater. A rain cap sized to the pot stops it; the smoke shelf gets cleaned while we are there.
Sea air reaches Moorabbin roofs and eats galvanised fasteners before the cap itself. We fit stainless or coated caps on corrosion-resistant fixings so the cap is still there, and still square, ten winters on.
A rotating cowl on a heater flue kit seizes with rust and stops working in a southerly, and smoke comes back into the room. We replace it with a fixed anti-downdraught cowl matched to the kit and confirm the draw with the heater lit.
Real photos from Melbourne jobs — not stock, not staged.
Post-war pots and flat mortar tops each take a different cap and a different fixing. We measure on the roof, fit the cap or cowl to suit the stack and the appliance below it, and seal it to the crown.
The finished cap is photographed from the roof and the photo comes with the invoice, so you can see it is square without going up. If the smoke shelf below was holding wet creosote, we mention it, because a cap stops the rain, not the deposit already there.

Yes. Flat-topped post-war stacks take a cap that fixes to the crown or straps around the top courses rather than clamping to a pot. We measure the flue opening on the roof, fit a stainless or coated cap on corrosion-resistant fixings and seal it to the crown.
Usually a cowl that has seized or blown off the heater flue kit, or an open pot with nothing on it. Wind off the bay pushes straight down the flue. A fixed anti-downdraught cowl sized to the kit is the normal fix, and we test it with the heater going.
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.
