Why do I need to rewire my home?
An electrical system will often display signs when there are potential problems. If you notice any of these warning signs, have an electrician inspect your electrical system:
- Frequent blown fuses or tripped breakers.
- An over-amped or over-fused electrical panel.
- Dimming or flickering lights, indicating the circuit is overloaded or has a loose connection.
- Hot or discolored switch plates, cords, or plugs.
- Light bulbs that frequently burn out in a socket, signaling a fixture that can't handle the bulb wattage.
- Buzzing or sizzling sounds.
- A burning smell.
- Arcs or sparks from an outlet when you plug or unplug a cord.
- Loose outlets.
- Cracked, cut, or broken insulation.
- Electrical shock when you plug in or touch a cord.
Other reasons to check the wiring:
Even if you don't notice any warning signs of faulty wiring, it's a good idea to have your home's electrical system inspected periodically. Electrical codes vary depending on where you live, but there are common situations that warrant an inspection from a qualified professional.
If your home is more than 40 years old.
If you're relying on extension cords for power.
If you've made major home improvements or added major new appliances that could strain your existing system.
If your home has ungrounded, two-prong outlets.
If your home has aluminum instead of copper wiring
Even when you don't see any of these warning signs, you can't go wrong with an expert electrical system inspection.
Whether you’ve just bought a property with old or dodgy electrical wiring or you’re in the process of renovating, you’ll probably need your home rewired. But rewiring a house is a task that can often get overlooked. Because electrical wiring is generally out of sight, it’s not usually considered a priority when moving into a house or renovating, unless an electrical problem is obvious.
It’s crucial that the wiring in your home is up-to-date and complies with Australian Standards to prevent the possibility of electrical hazards, fires or shock. It’s especially important to have the wiring looked at in older-style homes that may have had DIY electrical work done over the years, as it’s likely that this wiring is outdated, incorrectly installed and potentially dangerous.
How much does it cost to rewire a house?
Several factors will influence the cost to rewire your home. Copper wiring is not cheap, so the amount of wiring you need will naturally affect the overall cost. By some estimates, the average cost of the wiring alone is around $600. But your major cost will be labour. The labour cost to rewire your home will depend on two factors:
Your electrician’s hourly rate.
The ease or difficulty of access to your wiring.
When electricians quote for rewiring they’ll usually base their costings on their set rates per light fitting, switch, and outlet, plus the cost of replacing your switchboard and other miscellaneous work. The rates they charge for each outlet can vary (usually between $65 and $120). Rather than asking for their hourly rates or cost per switch, outlet and light fitting, when you get quotes for rewiring ask for detailed quotes for the whole job. It’s very important that you receive detailed, itemised quotes, because that will be the only way you can compare and know that you are getting truly competitive quotes.
Don’t be surprised if your quotes vary dramatically. Quotes for a typical three bedroom house can vary enormously. A low quote might sit around $4,000 and a high quote could be as much as double that amount.
