With bush and grassland close to most Gisborne homes, the top of the flue is a fire-safety fitting. FreshDuct fits spark arrestors, caps and cowls to ranges heaters and older chimneys, and clears them so they keep working.
Arrestor mesh clogged with creosote? A blocked arrestor chokes the fire and stops doing its job.
Gisborne is wood-heat country with bush and grassland at its edges, and that combination sets the priority at the top of a flue. Rain, birds and leaves matter as they do anywhere, but the first job of a cap on a ranges heater is to keep burning material inside the flue. A spark arrestor is a mesh cap that does exactly that, and on acreage and lifestyle blocks backing onto grass or trees we treat it as standard rather than optional.
The catch is that a heater which runs all day through a ranges winter coats that mesh in creosote, and a clogged arrestor throttles the fire, blackens the glass and sends smoke into the room. So an arrestor in Gisborne needs clearing every time the flue is swept, and sometimes between sweeps. We fit arrestors with mesh sized to stop embers without choking on the first month of deposit, and we show you how to tell when it needs a clean.
On the older brick chimneys in town the question is usually whether there is a cap at all. Many have stood open for decades, taking rain onto the smoke shelf and hosting nests. A cap with a bird guard and an arrestor mesh sorts both, sized to the pot and fixed so a ranges wind cannot lift it. Where an exposed house on a hill gets smoke back down the flue on windy nights, we test for downdraught and fit a cowl to suit.
Spark arrestors, bird-guarded caps and anti-downdraught cowls for Gisborne wood heaters and older brick chimneys, fitted from the roof and cleared at every sweep.
A flue on a heater that runs all day throws more sparks than one lit for an evening, and Gisborne has grass and bush to catch them. An arrestor mesh on every wood flue is where we start on a ranges property.
Heavy burning coats an arrestor in creosote until it chokes the fire. We fit mesh sized for a hard-run heater, clear it at every sweep and tell you what a clogged one looks like from the ground so you know when to call.
Older Gisborne chimneys have often stood open since they were built, and the ranges are full of trees to drop leaves down them. Leaf litter and nests end up on the smoke shelf; a capped, bird-guarded pot keeps them out and the flue dry.
Real photos from Melbourne jobs — not stock, not staged.
We size the arrestor or cap to the flue, fix it from the roof so wind cannot shift it, and check the heater draws properly with it on. Then we photograph it, so you can see the mesh is clear and the cap is square.
Because a ranges arrestor clogs, clearing it is built into every sweep we do in Gisborne. A cap that is fitted and then forgotten is not much protection by the end of winter.

We would fit one. An arrestor is a mesh cap that keeps embers inside the flue, and on a heater that runs all day next to dry grass it is the obvious precaution. It needs clearing at each sweep, because ranges heaters coat the mesh in creosote.
Probably, because it has clogged. Heavy burning coats the mesh in creosote until the flue cannot draw, and the symptoms are exactly those. Clearing it fixes it; if it clogs again quickly, the mesh may be too fine for a hard-run heater and we fit one that suits.
An open flue lets rain, leaves and birds straight in. A cap keeps the flue dry, keeps nests out and, on a wood heater, a spark arrestor stops embers leaving the flue.
Usually a downdraught — wind pushing back down the flue. An anti-downdraught cowl is the normal fix; we confirm the draw with a test before and after.
Yes. If we are on the roof for a sweep and the flue needs a cap, we can quote it on the spot and fit it the same visit where we have the right size.
