In Doreen the wood heater is often the heating system, running from autumn to spring in estate homes and on the acreage blocks alike. FreshDuct sweeps flues that work that hard, twice a season where they need it.
Heater on all day, every day? Book the second sweep for midwinter, not next autumn.
Doreen's estate homes around Laurimar run inbuilt and freestanding wood heaters on twin-wall steel flues, and the semi-rural blocks beyond them run bigger heaters and open fires with wider flues to match. What they share is the duty cycle. On the northern fringe a heater is not lit for atmosphere on a cold Saturday; it is loaded in the morning, kept in through the day and banked at night, for months on end.
That pattern changes what ends up in the flue. Long, low burns and wood that came off the block a little too early lay down a sticky tar rather than loose soot, and it builds on the baffle, the top of the firebox and the cool upper section of the flue where the gases slow down. A normal brush skates over it. Left for a second season it hardens into a glaze that only a rotary head with the right attachments will lift.
So a Doreen sweep is a heater service as much as a flue clean. The baffle comes out and is cleaned, the firebox and glass are done, the flue is swept its full length with a rotary head, and the cowl is checked for the litter and mesh clogging that open blocks produce. For a heater that runs daily we recommend this before the season and again partway through, with photos each time.
A full sweep for a Doreen wood heater or acreage open fire, sized to a flue that is expected to work every day of winter.
Block-cut wood that is not quite dry burns cool, and cool smoke leaves tar on the inside of a steel flue instead of dry soot. Tar needs a rotary head and patience to shift, which is why a Doreen sweep is never a two-minute brush from below.
A heater that goes from breakfast to bedtime for months builds deposit at a rate an autumn sweep cannot keep ahead of. We suggest a pre-season sweep and a midwinter one for the hard-run heaters, and say so honestly if yours does not need it.
On blocks backing onto paddocks and bush the cowl catches leaves, and the spark arrestor mesh fills with tar from all that daily burning. A choked terminal is the usual reason a Doreen heater stops drawing, so the top gets cleaned with the flue.

A Laurimar estate heater on a factory twin-wall flue and an open fire on an acreage block with a masonry chimney need different rods, different heads and a different conversation about the wood. We carry both and have the conversation either way.
Either way the finish is the same: a flue swept to clean metal or brick, a cowl clear of litter, and before and after photos so you can see what a season of daily burning left behind.

For a heater doing that kind of work, once before the season and once partway through. The deposit from months of long burns is tar, and tar builds into glaze if it is left a full year. If your burning is lighter, we say so and book you once.
Black glass is the fire telling you the smoke is cool and wet, usually because the wood has not dried long enough. It means the flue is tarring too. We sweep the flue, clean the baffle and glass, and look at the woodpile with you before we leave.
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.
