The ember checklist: what the RFS wants cleared from your gutters by October
Embers, not the fire front, destroy most homes — CSIRO puts it at roughly 85-90% of houses lost in bushfires. A gutter full of dry leaves is a firebed bolted to your roofline. The NSW RFS lists clearing gutters as core property preparation, and the statutory danger period runs October to March. Gutter cleaning starts at $180; most single-storey homes land between $220 and $430.
Embers do the damage, not the fire front
Picture how a house is lost in a bushfire and you probably picture a wall of flame. The research says otherwise. CSIRO's bushfire work puts it at roughly 85 to 90 per cent — the large majority of homes destroyed in bushfires ignite from ember attack, not the fire front itself. Embers travel well ahead of a fire on the wind, land on and around the house, and smoulder until they find something dry enough to take.
Gutters are the landing strip. They sit at the roofline, catch everything the wind carries, and by the end of winter most Sydney gutters hold a season of dry gum leaves and twigs — kindling, elevated and pressed against your fascia and roof edge. An ember that lands in clean metal usually goes out. The same ember in dry litter has fuel, airflow and a direct line toward the roof cavity. That is the whole argument for the clean.
What the RFS wants done before October
The NSW Rural Fire Service's property-preparation advice is blunt about it: clear the leaves and debris from your gutters. It sits on the same list as trimming overhanging branches and keeping the lawn down — the basic housekeeping that decides whether arriving embers find fuel. And the deadline is effectively fixed, because the statutory bushfire danger period in NSW runs October through March. Preparation done in November is preparation done during the season, not before it.
September is the month to move. The weather is still mild, most of winter's litter has finished dropping, and roof access is safer before the heat arrives. One honest caveat: gum trees do not read the calendar. If your block sits under heavy eucalypts, a September clean may need a top-up by January. A gutter clean is maintenance, not set-and-forget — anyone who tells you otherwise is selling something.
St Ives, Castlecrag, and every street that ends in trees
This is not an abstract exercise on the North Shore. St Ives backs onto Ku-ring-gai bushland. Castlecrag is wrapped in Middle Harbour reserve. Add Wahroonga, Northbridge, Killara — any street where the bitumen stops and the bush starts. These homes take continuous leaf drop straight into the gutters, and on a bad day they are among the first addresses wind-blown embers reach. The RFS checklist was written with exactly these properties in mind.
They are also the hardest homes to do yourself. Bush-edge blocks tend to be steep, two-storey and overhung by trees, which puts the gutter line a long way up a ladder on uneven ground. Ladder falls are the standard way this job goes wrong for homeowners. We carry the access gear, work to a safety system, and take the debris away with us rather than flushing it into the downpipes — where it would simply become the next blockage.
What a clean gutter can and cannot do
Be clear-eyed about what this buys you. A gutter clean removes one fuel bed — the one bolted to your roofline — and that is all it does. It will not fireproof the house, and it is one line on the RFS preparation list, not the whole list. Ember guards, sealed gaps under the eaves, a written bushfire plan: that homework is yours, not ours. We will only ever claim credit for the part we actually do.
The same clean pays a second dividend, though. Bushfire season and Sydney's summer downpours arrive together, and a gutter that cannot hold an ember also cannot hold a blockage. The first big storm goes down the downpipe instead of over the back of the fascia and into the eaves. One visit, two of summer's problems handled. If you want the full argument on the water side, we have written that one up separately.
A firm price now beats a ladder in December
Gutter cleaning starts at $180. Most single-storey homes land between $220 and $430 depending on gutter length, and two storeys adds about 50 per cent for the access. If the roof or the solar panels need doing at the same time, bundling services on one visit saves 5 to 15 per cent — the ladders are already up, so you pay for the work, not a second call-out.
You do not need to wait for a callback to know your number. The instant quote asks about the house — storeys, gutter length, tree cover — and returns a firm, bookable price in about 60 seconds. It holds unless the place is materially different from what you told us. Answer the questions, pick a September date, and when the danger period opens in October your gutters will already be the one item the RFS cannot fault.
