Thornbury has been renovated harder than almost anywhere in the inner north, and the fireplaces have had to keep up. FreshDuct sweeps, inspects and repairs them, with photo proof.
Renovated and now the fire smokes? That is usually air supply, not the chimney.
Thornbury sits in the leafy stretch of the inner north between Northcote and Preston, with High Street running through its heart and Merri Creek along its western edge. Its streets are full of Edwardian and Federation homes, California bungalows and Victorian cottages, most built with open fireplaces and brick chimneys. As the suburb has become one of the north’s most sought-after pockets, many of those fireplaces have come back into regular winter use.
The chimneys carry the character — and the wear — of their era. A Thornbury Edwardian or bungalow flue is generally unlined, so creosote settles on the brick, the mortar has softened over a century of weather, and the flashing where the chimney meets a tiled roof is a common source of the damp people blame on the gutters. On a renovated home where the fireplace is used often, that build-up matters.
FreshDuct works these homes carefully. We sweep and camera the flue, repoint tired mortar to match an Edwardian home or bungalow, and repair capping and flashing so water stays out. Every Thornbury job comes with before and after photos and honest, plain advice.
The things we look at first on a Thornbury chimney — based on the local housing and conditions.
Knocking the back of a Thornbury house into one room leaves the fireplace serving a far bigger volume than it was built for, alongside a powerful rangehood. The two compete for air, and the fire is usually the one that loses.
Renovations here very often put a wood heater or insert into the original Edwardian opening. That changes what the flue has to do, and without a correctly sized liner the old brickwork ends up carrying gases it was never intended to.
Where a fireplace was removed but the chimney kept, the stack stays on the roof with nothing maintaining it. We see plenty of these in Thornbury — open at the top, quietly taking water, and forgotten until a ceiling stains.

Every part of the chimney, handled by the one local team. Here is what each job involves on a typical Thornbury chimney.
Swept back to bare brick, with the debris bagged and taken away rather than tipped in your bin. You get before and after photos of the flue and the firebox.
A flue that still looks black straight after a sweep has glazed deposit, not loose soot. That is the point at which rotary cleaning becomes the only thing that will work.
Where a century-old flue has no known service history, a camera tells you far more than a look up from the hearth. We inspect the flue, crown and flashing and hand over a photo report.
Open unlined period flues are an easy target for nesting birds, and a nest in a tall stack can sit well out of sight. We remove it, clear the debris and cap the flue.
A period fire that smokes on lighting but settles once hot usually has a chamber full of deposit narrowing the throat.
Original terracotta pots and cast caps on period stacks crack and shift over the decades. We repair or reseat them rather than replacing with something that looks wrong on a Federation chimney.
Recast with a reinforced mix, a drip edge and an expansion joint around the pot, so it sheds water and does not crack straight back open.
Cracked, spalled or partially collapsed brick flues are common in homes this age. We camera the full length, identify where the flue has failed and repair or reline to suit.
Putting a wood heater into a period home usually means a new flue, since the original masonry chimney was never designed to vent one.
If a camera shows an unlined flue with open mortar joints, a liner is usually cheaper and safer than trying to repair the brickwork itself.
Water marks on the hearth or a damp smell after rain mean the flue is open to the weather and needs capping.
If you can rake mortar out of the joints with a finger, the stack is overdue and water is already getting into the brickwork.
Freed and repaired where the original casting is sound, or replaced with a top-sealing damper that also keeps weather out of the flue.
Reflashed in lead, dressed and chased into the mortar joint as it should be, rather than sealed over with mastic that fails within a year.
Brick faces flaking off the stack mean water has been getting in and freezing or salting behind the surface.
A period fireplace that smokes usually has a cause: an oversized opening, a restricted throat, or a stack that no longer clears the roofline after an extension. We diagnose before suggesting anything.
Old porous brick soaks up water and pushes it inside, but it still has to breathe. We use a vapour-permeable sealer that stops ingress without trapping moisture in the wall.
Restored with matched brick, lime mortar and an appropriate pot, so the chimney reads as original work rather than a repair.
Where a period stack is beyond repair above the roofline, we take it down to sound masonry and rebuild to match: same brick character, same profile, same pot.
An annual visit covering sweep, flue check and a look at the pointing, crown and flashing, with a photo record built up year on year.
Plenty of period fireplaces here have had a gas insert fitted into the original opening. We service the appliance and check the old flue is still venting it safely.
Most of the Thornbury fireplaces we are called to have not failed on their own. The house has been opened up, sealed up and fitted with serious extraction, and a flue sized for a small Edwardian sitting room is now expected to work in a very different building.
We look at the whole picture — opening size, air supply, what the appliance actually needs — and fix the cause. Often that means an air path or a correctly sized liner rather than anything dramatic.

The air did. A larger open room and a strong rangehood pull against the flue, so the fire can no longer draw. We test for it and usually solve it with a dedicated air path to the appliance rather than any work on the chimney itself.
Yes. A stack with no fireplace under it still needs a cap, sound flashing and a crown, or it takes water and passes damp into the wall below. We can cap and weather it so it stops being a liability.
