Keeping your home’s electrical system in top condition isn’t just about safety—it’s also key to energy efficiency and avoiding costly repairs. At Mastin Electrical, we often get asked what kind of electrical maintenance homeowners can do themselves, and how often it should be done. Here’s a quick guide to help you stay on top of it.

What Electrical Maintenance Can You Do Yourself?

There are a few basic DIY checks and tasks you can carry out safely. These include:

Test Your Safety Switches (RCDs)

Every 3 months, press the "Test" button on your safety switches. The power should cut off immediately—if it doesn’t, call an electrician.

Replace Smoke Alarm Batteries

Replace your smoke alarm batteries every year, unless they’re hardwired or 10-year lithium models. Also, vacuum the alarms gently to remove dust that can block sensors.

Check for Power Point & Switch Wear

Loose, warm, or discoloured power points and switches can be a sign of internal damage or overheating. If you spot any, have them replaced.

Light Globe Replacements

It’s safe to replace light globes yourself—just make sure the switch is off, and use globes that match the correct wattage.

What Needs Regular Professional Maintenance?

While DIY can help, there are certain areas best left to the pros:

Switchboard Inspections

Your switchboard should be checked every 3–5 years to ensure everything is up to current standards—especially if your home is older or you’re adding more appliances.

Wiring Health Check

Old or deteriorated wiring is one of the top causes of house fires. A full electrical inspection every 5–10 years is highly recommended, or sooner if you notice flickering lights or burning smells.

TV Antenna & Data Point Servicing

If you're experiencing poor reception or slow internet speeds, a technician can test and optimise your antenna or data cabling to improve performance.

Outdoor & Weatherproof Power Points

Outdoor sockets and lighting are exposed to the elements, so it’s smart to have them checked annually, especially before storm season.

How Often Should You Book a Professional Electrical Check?

Here’s a simple breakdown:

TaskFrequency
Safety Switch TestingEvery 3 months (DIY)
Smoke Alarm BatteryYearly (DIY/pro)
Switchboard InspectionEvery 3–5 years
Full Home Electrical InspectionEvery 5–10 years
Outdoor Power Points & LightingYearly
After Renovations or New InstallationsImmediately

Warning Signs You Should Never Ignore

  • Flickering or dimming lights
  • Sparking power points
  • Burning smells from switches or outlets
  • Circuit breakers tripping frequently
  • Electric shocks (even minor)

If you notice any of these, call Mastin Electrical immediately.

Keep It Safe. Keep It Simple.

Preventative electrical maintenance keeps your home running safely and efficiently. While a few checks can be done on your own, it’s important to know when to bring in a licensed electrician.
