Power problems? We find the fault, not just a patch

Tripping breakers, flickering lights, power that cuts out for no reason, it’s frustrating and it usually happens at the worst possible time. The real problem? Most faults get band aid fixes that don’t address what’s actually causing the issue. A few months later, you’re back to square one.

We don’t guess. We use proper testing gear, follow a structured fault finding process and track down the root cause before we touch anything. If it’s a single dead circuit in your home or intermittent faults across a commercial site, we isolate the problem and fix it properly. No repeat visits. No temporary patches. Just solid electrical work that keeps your power on.

Electrical fault finding is the process of systematically testing and inspecting your electrical installation to locate the source of a problem, if that’s a short circuit, an overload, an earth fault, damaged wiring or a faulty appliance. It takes patience, the right equipment and a sparkie who actually knows what they’re looking for.

Signs You've Got an Electrical Fault

Not every fault announces itself with a bang. Some are subtle, intermittent or easy to ignore until they get worse. Here’s what to watch for:
  • Circuit breakers or safety switches that trip repeatedly, even after you've unplugged everything
  • Flickering or dimming lights, especially when an appliance kicks in
  • Buzzing, crackling or humming from power points or switches
  • A switchboard or power point that feels warm to the touch
  • A burning smell near outlets or the switchboard, this one's urgent
  • Power loss in just one area of the property while the rest is fine
  • Power loss in just one area of the property while the rest is fine
  • Appliances that trip the circuit the moment they're plugged in
  • Signs of rodents, water damage or dodgy DIY wiring visible around your board or in the roof
If any of this sounds familiar, don’t wait. Small faults have a habit of turning into big ones.
We start by listening, when did it start, what’s changed, what exactly is happening. Then we test, using proper gear like insulation resistance testers and circuit tracers to measure what’s actually going on, not guess. We isolate circuits one at a time so we’re not shutting down your whole property and we physically inspect wiring, connections and switchboards for burnt terminals, water damage or loose connections. Once we find the root cause, if it’s a short, an earth fault, an overload or a faulty appliance, we fix it properly. No band aids, no repeat visits.

Electrical Faults We See Most Often

Short circuits

When a live wire touches a neutral or earth wire. Usually caused by damaged insulation, water ingress or a failed appliance. Trips breakers instantly and needs immediate attention.

Earth faults

Current leaking to earth, often picked up by your RCD. Common culprits include moisture in outdoor circuits, damaged cables and faulty heating elements in kettles, ovens or hot water systems.

Overloaded circuits

Too many high draw appliances on one circuit. Common in older homes and offices where the original wiring wasn’t designed for modern loads. The fix might be as simple as redistributing circuits or as involved as running new dedicated lines.

Loose or deteriorating connections

Terminals that have worked loose over time, creating resistance and heat. These are the faults that cause burning smells, warm switchboards and eventually, fires.

Faulty appliances or equipment

Sometimes it’s not your wiring at all. A failing fridge compressor, a kettle on its way out or an old air conditioner can trip circuits and send you chasing ghosts. We’ll test the appliance and tell you straight.

Rodent or pest damage

Rats and possums chewing through cables in roof spaces. More common than you’d think, especially in older Sydney homes and commercial premises near bushland.

DIY or unlicensed work from the past

Botched wiring from a previous owner’s “handy mate” that was never compliant and is now failing. We see this all the time and we fix it properly.

FAQS

No, we isolate circuits safely as we go, so only the affected areas are off while we work. We’ll always let you know what to expect before we start.
Yes. Intermittent faults are trickier but not impossible. We use testing gear that can catch faults under load and we’ll often replicate the conditions that trigger the problem to narrow it down.
Most electrical fault finding work is charged at an hourly rate, typically between 80 and 150 per hour. Straightforward faults might be resolved in an hour, while more complex or intermittent issues may take longer. We provide upfront pricing so you know what to expect before we begin.
If the fix requires parts or additional labour beyond the initial fault finding, we’ll give you a clear quote on the spot and schedule the follow up work at a time that suits you. No surprises, no hidden charges.
Yes. If you’ve got a burning smell, sparking or a complete loss of power, call us immediately. We prioritise urgent fault finding across Sydney.
