Balwyn's interwar and Edwardian homes carry tall brick stacks, often with several flues in one, built when briquettes were the fuel. FreshDuct sweeps each flue the full length, cameras it afterwards, and shows you the result in photos.
Not sure which flue serves which fireplace? We sort that out before the first rod goes in.
The chimneys along Balwyn's clinker-brick and tudor-revival streets were laid out in the 1920s and 30s around briquettes and coal, fuels that burned hot and steady and kept the flue walls warm. Almost every one of those fireplaces now burns wood. Wood is cooler and wetter, so the flue runs below the temperature it was designed for, condensation forms on the unlined brick, and the soot that settles is tarry rather than the dry powder a briquette fire left behind.
That tarry deposit is what a Balwyn sweep is really about. It does not fall to the grate; it bonds to the brick and, left another season, hardens into glaze that a soft brush skates over. We work each flue with rods and a rotary head from the firebox to the top of the stack, opening sealed and a contained vacuum running throughout. On a multi-flue stack we work out which flue serves which fireplace before we start.
Because these stacks are tall, the camera matters as much as the brush. Once the flue is clean we run a camera up it to confirm the walls are bare and to look at the state of the brick where it has been running cool for decades. If the deposit came off as glaze, or the mortar looks soft, we tell you plainly and photograph it. Often the practical advice is simply to burn drier wood and sweep a little more often.
A full-length sweep and clean of each flue in a tall interwar Balwyn stack, with the flue cameraed afterwards and the result photographed.
Balwyn fireplaces were sized for briquettes, and wood runs them cooler. The deposit is tarry and glazes quickly, so we go in with a rotary head rather than a soft brush and check on camera that the walls are actually clean.
A grand Balwyn chimney often carries two or three flues, and a rod pushed up the wrong one clears nothing. We trace each flue to its fireplace first, sweep them one at a time and note any that are no longer in use.
Interwar Balwyn stacks stand well above the roof, and the top few metres are where glaze collects and where nobody has looked in years. We add rods until the head reaches the pot and camera the full height rather than assuming.

A Balwyn flue that glazes every winter is usually reporting on the wood, not the chimney. Damp or unseasoned logs, damped down overnight, run a briquette-sized flue too cool. After the sweep we tell you what the deposit says about how the fire is being run, and what to change.
Where the glaze keeps coming back despite dry wood, an insulated liner that brings the flue up to temperature is the longer-term answer, and we say so with the camera stills rather than guess. Either way the photos of the flue before and after are yours.

Usually, yes. These flues were sized for briquettes and run cooler on wood, so deposit builds faster and glazes sooner. An annual sweep before winter is the minimum; if the fire runs most nights or is damped down overnight, a second sweep mid-season is sensible.
We sweep every flue that serves a working fireplace, and we work out which pot belongs to which room before starting. Flues that are no longer used are checked on camera and noted, so you know whether they need capping rather than sweeping.
Fire authorities recommend an annual sweep before winter. If you burn most nights, burn unseasoned or soft wood, or run a heater on low for long periods, sooner.
Not with FreshDuct. We lay drop sheets, seal the fireplace opening and use contained, high-power vacuuming so the soot is captured rather than left in your living room.
A standard sweep clears regular soot and light creosote. A deep clean tackles heavy, baked-on or glazed creosote that a normal brush will not shift.
