Caroline Springs heats on wood heaters and gas fireplaces with steel flues that run two storeys inside a boxed chase. FreshDuct sweeps the full length, cameras the section you cannot see and leaves photos of both.
Two-storey flue in Caroline Springs? The cool upper run is where the creosote sits, so we sweep to the top, not just above the heater.
Almost nothing in Caroline Springs has a brick chimney. The estates were built from the late 1990s on, and the heating is inbuilt or freestanding wood heaters and gas fireplaces venting through stainless twin-wall flue. On a double-storey home that flue leaves the heater, disappears into a plasterboard chase, jogs around a bedroom or a void and comes out somewhere above the upper roof. It is a long way for smoke to travel.
Length is the issue for sweeping. Gas that leaves the firebox hot has cooled considerably by the time it reaches the top of a two-storey run, and cooled smoke drops creosote on the flue wall. Every offset adds an elbow where deposits gather, so a Caroline Springs sweep works from the heater with the baffle out, rods pushed through each bend until the brush is at the cowl, and the loosened material captured below.
Because the middle of the flue is boxed in, we camera it after the sweep rather than assume it is clean. That photo record shows the joints and the state of the steel as well as the result of the brushing. Gas fireplaces get the flue side checked and cleared by us and anything on the appliance goes to the licensed gas specialists we arrange.

By the first-floor ceiling the flue gas has lost most of its heat, and that is where creosote condenses on a Caroline Springs flue. We sweep the top of the run as thoroughly as the bottom, because the top is where the build-up actually is.
Offsets around an upper bedroom or a void put bends in the flue, and a bend catches what a straight run lets fall. Each elbow is brushed through and then checked on camera so no ledge of soot is left behind.
Many estate homes have a gas fireplace rather than wood. We clear and check the flue and terminal so it vents properly; anything involving the burner or the gas connection goes to the licensed gas specialists we arrange.

A sweep on a two-storey estate home is only half a job if it stops where the flue enters the ceiling. We keep adding rods until the brush reaches the terminal, then run the camera up the concealed run to confirm the walls are clean and the joints still together.
On a double-storey home the heater is often on the ground floor with bedrooms above the chase, so we check the plasterboard beside it for heat marks while the camera is up. You get the before and after photos, and a straight answer on whether anything else needs doing.

Yes. The flue is swept from the heater up through the chase to the cowl, with rods added until the brush reaches the top. A sweep that stops at the ceiling leaves the creosote exactly where a two-storey run collects most of it.
The flue and terminal still need to be clear for the fireplace to vent safely, and we check and clear those. Work on the burner, valve or gas connection is done by the licensed gas specialists we arrange, not by us.
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.
