Chimney Nest & Blockage Removal in Melbourne — Clear the Flue.

A Blocked Chimney Is a Safety Risk

Uncapped Melbourne chimneys are an open invitation to birds and possums, and nests build up fast in spring and autumn. A blockage stops the flue venting, so smoke — and potentially carbon monoxide — backs into your home, and a dry nest is a fire hazard. FreshDuct removes the blockage, cleans the flue and checks it draws safely.

The lasting fix is a properly fitted cap or cowl with a guard, which keeps wildlife and rain out while letting smoke escape. We can also trace any lingering odour to its source.

Blockages aren’t always wildlife — fallen render, a slipped brick, leaves or old debris can choke a flue too. Whatever the cause, the symptoms are the same: poor draw, smoke in the room and a fireplace that won’t behave.

How We Clear a Blocked Chimney

Safe, humane and thorough:

Live wildlife is handled humanely; where protected animals are involved we coordinate with licensed wildlife rescue as required.

Blockages, Smoke and Carbon Monoxide

When a flue can’t vent, the gases from your fire have nowhere to go but back into the room. That means smoke, soot on the walls, and a genuine carbon monoxide risk — which is why you should never light a fire if you suspect a blockage.

A dry nest packed with twigs is also flammable, sitting right in the path of heat and embers. Clearing it removes both the venting problem and the fire hazard in one visit.

Melbourne’s mix of old uncapped chimneys and plenty of birdlife makes this one of the most common chimney call-outs we get — especially heading into autumn as fireplaces come back into use.

Which Animals, When, and How to Keep Them Out

In Melbourne, the usual culprits are birds — particularly in spring and autumn nesting seasons — along with possums looking for a warm, sheltered cavity. An open, uncapped flue is effectively an invitation, and a single season is enough to build a substantial blockage.

The signs are distinctive: scratching or fluttering sounds, twigs or droppings in the firebox, a musty smell, and a fire that suddenly won’t draw. Because a packed nest blocks venting, smoke — and carbon monoxide — can push back into the room, so it’s a job to act on rather than ignore.

Some birds are protected, and active nests with young are handled accordingly — we coordinate with licensed wildlife rescue where required rather than simply clearing them. Our aim is a safe, humane outcome and a clean, working flue.

The permanent fix is prevention: a properly fitted cap or cowl with a guard keeps wildlife and rain out while still letting smoke escape. Fitting one straight after clearance means you don’t end up back where you started next season.
