Craigieburn's estate homes heat with wood heaters and gas fireplaces on steel flues, not brick chimneys. FreshDuct sweeps the flue, clears the baffle and checks the cowl, then shows you the before and after photos.
Heater turned down low overnight? That is exactly how a steel flue builds creosote.
Craigieburn was built up in the last couple of decades, so its heating runs through steel rather than brick: freestanding and inbuilt wood heaters with twin-wall flues rising through the roof, and gas fireplaces alongside them. There is no smoke shelf, no tall masonry stack and no century of soot. What there is instead is a narrow, smooth flue that carries every bit of creosote a slow-burning heater produces, and a baffle plate above the firebox that catches whatever falls back down.
The usual Craigieburn problem is a heater turned right down through the night. That keeps the room warm and the flue cool, and a cool steel flue condenses smoke into creosote in a matter of weeks. We sweep with a brush matched to the flue diameter, working from the heater up or the cowl down depending on the installation, with the firebox sealed and a vacuum capturing what comes loose. The baffle comes out, gets cleared and goes back in.
Gas fireplaces need their flue kept clear too, and we do that part; anything on the appliance side goes through the licensed gas specialists we arrange. On a wood heater we finish by checking the cowl from the roof, confirming the draw with the door shut, and photographing the flue before and after so you can see what a season of slow burning left behind. If the baffle or door seal looks worn, we tell you rather than leaving it for next winter.

Modern homes hold their heat, so heaters get turned down rather than stoked. A steel flue running cool condenses smoke into creosote quickly, and it is the sticky kind. We brush it out with a head sized to the flue and show you the photos.
Plenty of Craigieburn homes run a gas fireplace instead of, or as well as, a wood heater. We keep the flue path clear and check the terminal; work on the appliance itself goes through the licensed gas specialists we arrange.
On a modern heater the flue is only part of the path. Creosote that drops during the sweep lands on the baffle, and a blocked or rusted cowl chokes the draw from above. Both get cleared and checked as part of the sweep.

A wood heater in a newer Craigieburn living room sits on tiles or carpet that are still new. We sheet the area, seal the firebox and run the vacuum for the whole sweep, so the only sign we were there is a heater that draws better.
Steel flues hide their condition well, so we photograph inside before and after and check the cowl from the roof. If the flue is clean and the cowl sound, that is what we tell you.

Yes. The age of the house has nothing to do with it; a steel flue collects creosote from the first winter, and a heater run low overnight collects it sooner. Once a year before winter is the sensible routine, sooner if the glass blackens quickly or the draw has dropped.
We keep the flue path clear and check the terminal on the roof, which is the part of a gas fireplace we handle. Servicing of the burner and the appliance itself goes through the licensed gas specialists we arrange, and we can line the two up for you.
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.
