Electricity powers everything in your home — from your lights and appliances to your heating and cooling. But when something goes wrong, it can be more than an inconvenience — it can be dangerous. At Mastin Electrical, we want to help you stay safe and informed. Here are some of the most common residential electrical problems and emergencies to watch out for, and when it's time to call a licensed electrician.

1. Tripping Circuit Breakers

If your circuit breakers are constantly tripping, it could indicate:

  • An overloaded circuit
  • A short circuit
  • A ground fault

While resetting a breaker is easy, repeated tripping is a warning sign. Don’t ignore it — it’s best to have your switchboard inspected before a small issue becomes a big hazard.

2. Flickering or Dimming Lights

This could be caused by:

  • Loose wiring
  • Voltage fluctuations
  • Overloaded circuits
  • Faulty fittings

Flickering lights might seem minor, but they can be a sign of underlying electrical issues. Especially if multiple lights are affected, it’s worth getting it checked.

3. Power Outages (Localised)

If the rest of your street has power and your home doesn't, it’s often:

  • A blown fuse or faulty breaker
  • Wiring damage
  • Faulty appliances or connections

We can help isolate the issue quickly and get you back online.

4. Burning Smells or Scorch Marks

This is an emergency. Burning plastic or electrical smells usually point to:

  • Overheating wires
  • Melting insulation
  • Failing power points or switches

Turn off power to the affected area immediately and call an electrician. These are often precursors to electrical fires.

5. Buzzing Noises

Electricity should be silent. If you hear buzzing from outlets, switches, or your switchboard, it may be due to:

  • Loose wiring
  • Faulty components
  • Unsafe electrical loads

This needs to be addressed ASAP to prevent shock or fire hazards.

6. Dead Power Points or Switches

If a power point suddenly stops working, it could be:

  • A tripped safety switch
  • Faulty wiring
  • A damaged device shorting the circuit

Don't attempt DIY repairs — safety first. We can test and safely repair or replace damaged points.

7. Electric Shocks

Even a minor tingle from a tap, switch, or appliance is serious. Shocks may be due to:

  • Faulty earthing
  • Damaged wiring
  • Water ingress

This is a clear danger and should be looked at by a qualified electrician immediately.

8. Old or Outdated Wiring

Homes over 30 years old may still have:

  • Ceramic fuses
  • No safety switches (RCDs/RCBOs)
  • Cloth or rubber-insulated wiring

If your home hasn’t had an electrical inspection in decades, it’s time for a professional check-up.
