How to Prepare Your Fireplace for Winter

Winter in Australia can sneak up on you, with cool mornings and darker evenings suddenly leaving you reaching for the switch, the valve, or the first log of the season. Before that moment comes, a considered approach to fireplace preparation makes the difference between a seamless first burn and an expensive, inconvenient problem.

Here’s how to get your fireplace ready for winter, whatever fuel type you have.

Quick Answer

• Schedule a professional inspection and flue clean before your first fire
• Check glass, seals, and gaskets for wear on all enclosed fireplace types
• For wood-burning systems, source seasoned hardwood with less than 20% moisture content
• Test detectors and ventilation
• Service gas and bioethanol systems with a licensed technician annually

Start with a Professional Inspection

The most important step for any fireplace is an annual inspection before the season begins. Certified professionals can identify hidden dangers such as creosote build-up, cracks in the flue liner, or blockages caused by nests and debris that accumulated over the warmer months.

For wood fireplaces and slow combustion wood fireplaces, this is non-negotiable. Creosote is among the primary causes of chimney fires, and it builds silently between seasons. Fire and Rescue NSW advises having your chimney serviced by a qualified tradesperson before each season.

Gas fireplaces require a licensed gas fitter to inspect burners, igniters, and flue integrity. Bioethanol units should have their burner components checked and cleaned according to the manufacturer’s schedule.

Clean the Firebox and Flue

Once inspected, a thorough clean is essential. Remove accumulated ash from the firebox, wipe down glass panels with an appropriate cleaner, and check that all seals and gaskets on in-built wood fireplaces are intact. A compromised seal reduces combustion efficiency and can allow smoke to enter the room.

For open flue systems, confirm the damper opens and closes properly. A damper left open over summer becomes a route for birds, insects, and moisture.

Source Quality Firewood Early

For wood-burning installations, firewood quality defines the entire experience. It’s recommended that you buy firewood in spring or summer, storing it in a covered stack with good air circulation, and aiming for a moisture content of 12–20%.

If wood hasn’t dried to below 25% moisture content, it burns less efficiently, producing more smoke and less heat and risk damaging your fireplace. A simple digital moisture meter takes the guesswork out entirely.

In Australia, dense native hardwoods such as Red Gum and Ironbark are considered among the highest-performing species for heat output and burn duration. Contrary to popular belief it is better to burn smaller logs as your fire will burn more cleanly and produce better heat.

Check Your Safety Devices

Test smoke and carbon monoxide detectors and replace batteries. Homes with solid- or liquid-fuel heating appliances should have a CO detector installed on every level. For gas systems, this is particularly important as carbon monoxide is odourless and invisible.

Ensure at least one metre of clear, non-combustible space around the hearth, and confirm that your fire screen or glass panel is in place and undamaged.

Winter Is a Design Moment

A well-prepared fireplace isn’t just safe, it also performs beautifully. As fireplaces in Australia continue to evolve alongside contemporary architecture, the most considered homes treat the hearth as a centrepiece: architecturally resolved, beautifully finished, and ready to deliver warmth from the first evening of May through to September.

At Oblica, we work with homeowners, architects, and designers across Melbourne and Sydney to specify and install wood, gas, and bioethanol fireplaces that perform as precisely as they look.
