Queensland's cyclone season officially runs from 1 November to 30 April, according to the Queensland Government's Get Ready Queensland program, though cyclones and severe storms can and do happen outside that window too (Get Ready Queensland). For most homeowners across the Sunshine Coast, Noosa and Moreton Bay, that first week of November is a useful line in the sand for getting the outside of the house properly ready, and gutters are one of the most commonly overlooked parts of that prep.
Why blocked gutters matter more than they look like they do
A gutter half-full of leaves and debris doesn't look like an emergency, but it changes how the house handles a heavy downpour. Instead of carrying water away from the roofline, a blocked gutter forces water to back up and overflow at whatever point is weakest, usually straight down the fascia board, behind the gutter line, or pooling right at the point where water is meant to be carried away from the foundations. None of that is obvious on a dry day, which is exactly why it tends to get noticed for the first time during the first big storm of the season, rather than before it.
What to actually check
Leaf litter and debris build-up. This is the most common issue in this part of South East Queensland, particularly on properties with overhanging gums, jacarandas or other established trees that drop leaves and seed pods year-round rather than in one clear autumn window.
Blocked or disconnected downpipes. A gutter can be clear and still fail if the downpipe itself is blocked further down or has come loose from the gutter outlet.
Sagging sections. Gutters that are pulling away from the fascia, sitting unevenly, or visibly sagging between brackets are carrying more weight than they're designed for, usually from trapped water and debris, and are at higher risk of failing outright in a heavy storm rather than just overflowing.
Staining on the fascia or external walls below the gutter line. This is usually a sign that water has already been overflowing in that spot, even if the gutter looks mostly clear on a casual glance from the ground.
DIY versus calling a professional
A single-storey home with easy, safe ladder access and gutters that just need debris cleared out is a reasonable DIY job for anyone comfortable working at that height. It stops being a straightforward DIY job once you're dealing with a second storey, a steep or awkward roofline, gutters that are already sagging or pulling away from the fascia (which is a repair job, not just a clean), or a property where safe ladder placement genuinely isn't possible from the ground. Working at height is also where most gutter-related injuries actually happen, not from the gutters themselves.
What it typically costs
General cost guide data for Australian gutter cleaning puts single-storey homes at roughly $100 to $400 per clean, two-storey homes at roughly $180 to $600, with an overdue clean carrying heavy debris build-up, or a clean that also needs downpipes flushed, sitting above that range (cost guide data via whatsthedamage.com.au). Those are general market figures, not a quote for your specific property, since the actual price depends on roof size, pitch, access and how overdue the clean is.
The bigger picture
Gutters are one part of a wider pre-storm-season checklist that Get Ready Queensland also recommends, including securing loose items around the yard that can become debris in strong winds, and checking your home's broader readiness if you're within range of coastal or cyclone-prone areas (Get Ready Queensland). Gutters are an easy one to tick off early, well before the first storm warning of the season actually goes out.
