When it comes to keeping your home warm and cosy in Wanaka, Hawea, Cromwell, and the surrounding areas, nothing beats a logburner or fireplace. But without proper care, your chimney and fire can lose efficiency and even put your home at risk. Every year, preventable issues like smoke problems, creosote build-up, or worn components cause trouble for homeowners. The good news? With the right maintenance and habits, you can keep your fire running safely and efficiently.
Here are four key fire and chimney safety tips to help keep your fire running well and protect your home:
1. Soot and Creosote Build-Up
When wood burns, it produces substances called soot and creosote.
Soot is a fine, powdery black residue from incomplete combustion. While less flammable than creosote, large deposits can restrict airflow in your chimney.
Creosote is a tar-like substance that forms when smoke cools and condenses on the flue walls and inside the cowl (chimney cap). It can start flaky but become sticky, shiny, and rock-hard in layers — and it’s highly flammable, making it the main cause of chimney fires.
If you hear clunky bits of creosote trickling down your flue, don’t be tempted to bang on the flue — the creosote will land on the baffle plate and quickly block the flue completely.
✅ Prevention Tip: Have your chimney swept regularly (at least once a year, or more if you use your fire often or your fire is old). Always burn dry, seasoned wood to minimise creosote build-up.
2. Blockages in the Flue
Birds, nests, and even small creatures can find their way into chimneys and block airflow. This can cause smoke to spill back into the room, create a carbon monoxide hazard, or worse still, lead to a chimney fire.
I once had to clear out a baby possum that had died after getting stuck in a client’s flue. It was so sad, horrible to remove, and the blockage had caused smoke to fill their lounge.
It’s not unusual to come across dead birds or old nests blocking chimneys, fires, and flues. Every now and then though, I’m lucky enough to rescue a live bird too.!
✅ Prevention Tip: If you live in a rural area, have a holiday home that’s vacant for long periods, or are having issues with birds nesting, we can install protective meshing around your cowl to keep your fire and flue clear. Always have your chimney looked over if you notice smoke backflow or reduced airflow.
3. Poor Ventilation in New Builds
Modern homes are often very airtight, which is great for energy efficiency but can restrict the fresh air your log fire needs to draw in to burn properly. Without enough airflow, smoke can spill back into your room, your fire may be difficult to light, or it might not burn efficiently.
Additionally, extractor fans and Heat Transfer Systems can compete with the airflow your fire relies on, making these issues worse. If you notice smoke when lighting your fire, make sure these systems are switched off until the fire is well established. Proper airflow ensures a safer, cleaner, and more efficient burn.
✅ Prevention Tip: Crack a window slightly when lighting your fire to improve airflow. If problems persist, call us to discuss alternate solutions.
4. Regular Maintenance
The biggest issue is neglecting your fire and chimney altogether. Small problems — like smoke backflow, soot build-up, or worn components — can quickly escalate into serious safety hazards, including blocked flues, carbon monoxide risks, or even chimney fires.
Many parts of your log fire or fireplace, such as seals, gaskets, insulation bricks, baffles, and airtubes, are perishable and will naturally wear out over time. If these aren’t regularly checked and replaced, the efficiency of your fire decreases, and your home could be at risk.
Regular maintenance not only keeps your fire safe but also ensures it burns efficiently, saves on fuel, and extends the life of your appliance.
✅ Prevention Tip: Make chimney sweeping part of your yearly routine. Just like your car needs servicing, so does your fireplace. We can add you to our annual chimney sweep list and send reminders — be sure to ask at your next service.
Stay safe and cozy
A warm fire should bring comfort — not worry. By taking a little extra care and getting your chimney professionally checked, you’ll enjoy peace of mind every time you light it.
