Salt wind off Port Phillip is what wears an Altona chimney out. FreshDuct replaces corroded flashing, repoints fretting mortar, rebuilds crowns and relines failed flues on beachside homes, with a photographed inspection before any quote.
Rust streaks on the roof below an Altona chimney? That is the flashing or the cap giving up, and both are repairable.
Altona's chimneys are mostly mid-century brick, which means they are younger and squatter than the period stacks of the inner suburbs, but the bay makes up the difference. Salt-laden wind hits the stack every day of the year, the galvanised flashing and cap corrode first, and once water gets behind them the mortar joints on the exposed faces begin to fret and the brick faces flake.
The order matters, because it tells us where to look. A damp mark on the chimney breast or a rust stain running down the tiles almost always starts at corroded flashing, not at the brickwork, so we inspect and photograph the flashing, crown and cap before anyone talks about repointing. On a weatherboard home with an external stack, we also check where the stack meets the cladding.
Repairs are then matched to what the photos show. Rusted flashing is replaced with a corrosion-resistant material and sealed to the roof, fretted joints are raked and repointed, spalled bricks are cut out and replaced, and a cracked crown is rebuilt to shed water away from the stack. Where a flue has cracked or an old open fire is getting a wood heater, we quote a stainless liner after a camera inspection.
Flashing, crown, mortar and flue repairs for salt-worn Altona chimneys, priced firm once we have photographed what has actually failed.
Near Altona Beach, galvanised flashing rusts at the fixings and lifts within a fraction of its inland life. We replace it with a corrosion-resistant material and seal it to the roof so water stops tracking behind the stack.
Salt crystallising in damp mortar pushes the joint apart from the inside, which is why the exposed face of an Altona stack looks sandy and hollowed. We rake the failed joints out and repoint in a mortar that lets the brick dry.
Mid-century bricks and the harder mortar of the era spall differently from Victorian work. We match the brick and the joint so a repaired Altona stack does not show a patch, and we never render over a problem to hide it.
Real photos from Melbourne jobs — not stock, not staged.
Most Altona chimney leaks trace back to metal, not masonry. Fixing corroded flashing and a rusted cap before the mortar behind them fails is a modest job; leaving it a few winters turns it into repointing and brick replacement as well.
We photograph the fault before quoting and the repair before invoicing, so you see the rusted flashing come off and the new work sealed down without setting foot on the roof.

It is the early warning. Rust streaks mean the flashing or cap is corroding in the salt air, and water is probably already getting behind it. Replacing the flashing now is a small repair; the mortar and brick behind it stay sound if it is done before they get wet through.
Usually a camera inspection and often a stainless liner. Mid-century brick flues were built for an open fire, and a heater running through an unlined, salt-weathered flue will deposit creosote on the brick and find every crack. We inspect first and quote the liner firm.
White staining, crumbling mortar, loose or missing bricks, rust marks on the roof, water in the firebox after rain, or smoke seeping into rooms are the usual signs. A photographed inspection tells you what is cosmetic and what is not.
Yes — stainless steel liners for cracked or unlined flues on open fireplaces and wood heaters, quoted firm after a camera inspection. Gas flue work goes through the licensed gas specialists we arrange.
Often, with roof access and harness work. Taller or unstable stacks need scaffold, and we tell you before quoting rather than after.
