Between the interwar stacks near Eaton Mall and the post-war chimneys of South Oakleigh there is a lot of weathered mortar and a lot of slipped flashing. FreshDuct repoints, replaces bricks, reseals flashing and relines unlined flues, quoted after photographs.
White streaks down an Oakleigh chimney after rain? Water is passing through the joints, and repointing stops it before the brick goes.
Repairing an Oakleigh chimney starts with knowing which era you are standing under. An interwar stack is taller, carries more weight and was laid in a softer mortar; a post-war one is shorter, in a harder mix, with a plain cement crown on top. They fail differently. The older stack loses its joints to fretting and its crown to cracking; the newer one tends to lose its flashing first and its top courses second.
What they share is exposure. The stack sits above the roofline with nothing shielding it, and the joints on the weather side open before the ones facing the house. Water in an open joint soaks into the brick behind it, lifts the face as it dries, and the white staining that follows is lime washing out of the mortar. Left long enough, the top courses loosen and the flashing at the roofline is pulled out of its chase.
Every Oakleigh repair is photographed first and quoted for what has failed, not for the whole stack. We rake and repoint fretted joints in a mortar matched to the era, cut out and replace spalled bricks, reform cracked crowns and reseal or replace flashing. Where the camera shows an unlined flue with open joints inside, a stainless liner is quoted firm as the fix that stops smoke and heat reaching the brickwork.
The masonry, crown, flashing and flue repairs an original Oakleigh stack needs, matched to whether it was built between the wars or after.
Interwar joints want a softer mix and post-war joints a harder one, and getting it wrong shortens the life of the repair. We match the strength and the colour to the existing mortar so the stack sheds water evenly.
As the mortar frets, the flashing let into it loses its grip and lifts, and rain runs down the stack into the ceiling. We reset it in a fresh chase or replace it, and seal it so the fix outlasts the pointing around it.
Most original Oakleigh flues have no liner, and when the joints inside open up, smoke and heat reach the brick. After a camera inspection we quote a stainless liner sized to the flue, which restores a safe passage without rebuilding the stack.
Real photos from Melbourne jobs — not stock, not staged.




Water in the firebox, staining on the breast or mortar in the gutter each point somewhere different on an Oakleigh stack. We inspect crown, joints and flashing together and show you which one has failed before quoting.
The repair is done from the roof with harness access where the pitch allows, and the after photos show the joints, crown and flashing finished, so you are not taking our word for it.

Rarely. White streaks are lime washing out of open joints, and loose mortar at the top is fretting, both of which repointing fixes if the bricks are still sound. We photograph the stack and quote repointing and any brick replacement; a rebuild is only quoted if the top courses have actually moved.
Yes. After a camera inspection shows the state of the joints inside, we quote a stainless steel liner sized to the flue and the appliance. It gives an open fire or a wood heater a sealed passage without disturbing the original brick outside. Gas flues go through the licensed gas specialists we arrange.
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.
