Burnt Smells in Your Leichhardt Home
A burning or hot-plastic smell with nothing obvious causing it is never something to shrug off. It's usually the earliest warning an electrical fire gives before anything is visible.
Trust the smell over your eyes here. Heat and melting insulation happen before flames or visible damage most of the time.
If the smell is strong, or you can see smoke, get everyone clear and call (02) 9538 7356 right away.
What a Burnt Smells Actually Means
Overheating insulation and overheating plastic fittings smell distinctly different from ordinary household smells, and most people recognise it instantly even without knowing the cause.
That smell means something is running hotter than it's supposed to. Usually a loose connection, an overloaded circuit, or a failing component generating resistance heat.
Resistance heat builds quietly at first, at a loose terminal or a worn switch, long before it's hot enough to melt anything nearby.
Once insulation or plastic housing starts to soften, that's when the smell becomes noticeable, and it means the fault has already progressed past the earliest stage.
A smell that comes and goes with a specific appliance is different again, and usually points to that appliance rather than your home's wiring.
Should You Worry? An Honest Answer
Yes, treat any unexplained burning smell as worth acting on quickly. This isn't a symptom that benefits from a wait-and-see approach.
A smell paired with visible smoke, sparking, or a switch too hot to touch is a genuine emergency. Kill power at the mains if that's safe to do, then ring straight through to us.
A fainter smell with no other symptoms still warrants an urgent call, not a routine booking, since the underlying cause is still generating heat somewhere.
Location matters too. A smell near the switchboard itself carries more weight than one near a single appliance, simply because a board fault has more wiring behind it to affect.
The one exception worth knowing: a new appliance or a heater running for the first time can sometimes give off a mild burning smell as protective coatings cure. That typically fades within an hour and isn't a wiring issue.
Six Causes, From Common to Rare
Work down the list roughly in this order:
- A loose connection in a power point or switch. Resistance heat builds at the loose joint until insulation nearby softens.
- An overloaded circuit. Too much current for too long heats the cable itself, not just the connection point.
- A failing appliance. A worn motor or heating element can smell burnt well before it stops working entirely.
- Ageing wiring insulation. Older cable insulation can degrade and smell faintly when a circuit runs hot.
- A damaged extension cord or power board. Frayed internal wiring under a rug or furniture is an easy one to miss.
- A pest issue inside a wall cavity. Rare, but rodents chewing insulation can expose bare wire that then overheats.
Three Safe Steps To Take Now
- Track down the source if you safely can. Note the room and the point, switch or appliance involved.
- Kill power to the suspect item at the wall or the switch, then watch whether the smell fades over a few minutes.
- Head to the mains if it doesn't clear or you can't pin it down, and book us in straight away.
How We Fix It, Step by Step
We treat a burning smell as a fault-finding job from the first call, not a routine repair. Thermal imaging locates heat that isn't yet visible, which speeds up finding the actual source.
Whatever's generating the heat, a connection, a switch, a section of cable, gets isolated and replaced or repaired properly rather than patched.
We'll also check nearby points and circuits while we're there, since heat damage doesn't always confine itself neatly to the original fault.
Once the repair's finished, notifiable jobs get lodged as a Certificate of Compliance, your proof it now meets AS/NZS 3000.
You're given a written price before any repair work begins, once the fault's been confirmed.
Preventing the Next Burnt Smells
Cutting the risk of this happening again usually comes down to a few practical steps:
- A full switchboard and wiring inspection, especially where the home hasn't had one in years. More at switchboard upgrades.
- Replacing worn power points and switches before a loose connection gets the chance to overheat.
- Not overloading power boards or double-adapters, a common and easily avoided cause.
- Getting older appliances serviced or replaced once they start running warmer than usual.
- Booking a repair check on wiring more than a few decades old, exactly the kind of job our electrical repairs crew handles weekly.

Common questions
Burnt Smells FAQs
The questions people ask us most when something smells wrong.
Is a burnt smell an emergency?
Yes, act on it as one. A smell like scorched plastic near anything electrical means heat is building somewhere it shouldn't be, which is exactly how an electrical fire starts before flames appear.
Should I mention the smell to my insurer, or just get it fixed?
Get it fixed properly and keep the paperwork. That written record is exactly what you'd want on hand if the smell ever turned out to be connected to a later claim.
Will my safety switch protect me?
A safety switch guards against electric shock. It does nothing for fire risk from an overheating connection, since the two faults behave completely differently, which is why a burning smell always needs its own look.
What tools do you use to track down a smell with no obvious source?
A thermal camera, mainly, since it shows up heat that's invisible to the naked eye. We scan the suspect area first, then narrow in with a physical check of whatever's reading hot.
How do I tell whether it's the appliance or the house wiring?
Pull the plug on whatever's closest to the smell and wait a minute. Gone, and the appliance was to blame. Still there with nothing plugged in, and the fault is in the point or the cable behind it.
Is it worth killing the mains overnight just in case?
If you genuinely can't work out where the smell's coming from, yes, that's a sensible precaution until we've had a proper look.
