Colonial brick and bluestone in Williamstown was laid in lime mortar, and salt off the bay has been working on it ever since. FreshDuct repoints in a compatible lime mix, replaces fretted brick, rebuilds crowns and refits flashing on cottage and Victorian stacks, quoted after photographs.
Grey cement pointing on a Williamstown cottage stack? It is lifting the brick face around every joint, and the fix is lime, not more cement.
The chimneys on Williamstown's colonial cottages and Victorian homes are among the oldest we work on, and they were built on a principle that modern repairs often ignore. Brick and bluestone were bedded in soft lime mortar so that moisture in the wall would leave through the joint rather than through the masonry. On an exposed point with salt arriving on every wind, that sacrificial joint has been doing its job for a long time and is often simply worn out.
The damage we see most is not the worn lime but what has been put over it. A previous owner or a general builder has raked out the soft joints and filled them with hard grey cement, and the wall can no longer breathe through them. Moisture and salt now leave through the brick face instead, which spalls and crumbles around every joint while the cement sits proud and intact. Rendered patches, rusted galvanised flashing and cracked crowns finish the picture.
Our repair follows the original logic. Cement pointing is cut out where it is doing harm, joints are repointed in a lime mix compatible with the old work and matched in colour, and fretted bricks or bluestone are replaced with matching salvage rather than patched. Crowns are rebuilt to throw water clear of a low stack, and flashing is replaced in a material that will not corrode in salt air. Everything is photographed before and after and quoted firm first.
Lime-mortar repointing, brick and bluestone replacement, crown rebuilds and corrosion-resistant flashing for Williamstown's colonial and Victorian chimneys, matched to the original.
Soft lime joints are meant to wear so the masonry does not. We repoint in a compatible lime mix, matched for colour and struck to the original profile, so the stack sheds moisture through the joints again instead of through the brick face.
Salt reaches a Williamstown stack from every direction, so the mortar frets all round rather than on one weather side. We photograph the whole stack, repoint what has gone, and replace fretted brick or bluestone with matching salvage.
A cottage stack sits so close to the ridge that its flashing takes the full run of the roof. Galvanised steel rusts out here in short order; we replace it in a corrosion-resistant material and dress it into a lime joint properly.
Real photos from Melbourne jobs — not stock, not staged.
A crumbling brick face on a Williamstown chimney is usually the joint's fault, not the brick's. We photograph the stack, show you where hard pointing is forcing moisture through the masonry, and quote to put it right rather than to render over it.
The finished work is photographed from the roof, so you can see the lime joints, the rebuilt crown and the new flashing without climbing up, and keep the record with the house.

Because the mortar is the problem. Hard cement pointing over soft colonial brick stops moisture leaving through the joint, so it leaves through the brick face and takes the face with it. We cut out the cement where it is doing harm and repoint in a compatible lime mix so the brick stops spalling.
Yes. Bluestone stacks were bedded in lime like the brick ones and suffer the same way when repointed in cement. We repoint in a lime mix suited to the stone, replace fretted stones with matching salvage where needed, and rebuild crowns and flashing so the stack sheds water.
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.
