Rewiring Old Homes in New Zealand: A Comprehensive Guide

Choosing to live in an old house comes with plenty of benefits. For starters, most old properties are known for their durable built, quaint charm, rich history, and intricate design. They also give you plenty of room for renovation projects because they’re more affordable than move-in ready homes. Then, there’s also the matter of their location. Most of the time, these properties are situated in pleasant and quiet neighborhoods, making them ideal for growing families. 

But of course, it’s no secret that old homes do need a little bit of work before they become suited for living. One of the most crucial things you must check is the condition of the wires. Find out if you need to call in a professional to rewire your home.   

What are the signs you should rewire an old house?

Outdated and deteriorating wiring can cause all kinds of mishaps, including electrocution and fire. Fortunately, there are a few tell-tale signs that you can look out for to prevent potential risks. Some examples include:

  • Tripping of the circuit breakers or fuses
  • Intermittent or regular flickering of appliances and lights
  • Odd buzzing or humming sounds coming from the power outlets
  • Burning or acrid smell near the outlets

The signs above usually apply for any type of house. Sometimes, such issues arise after 5 to 10 years without rewiring done. For much older houses, such as as those more than 20 years old and has never been rewired before, it’s highly recommended to book an appointment with a residential electrician. 

Even if you don’t notice any of the signs enumerated above, it’s best to have your property checked as soon as possible. This way, you can figure out what you need to update and how much work you need to do. It will also allow you to bring your home electrical system to the latest industry standards. 

Besides addressing possible causes of accidents, rewiring your old home can also improve the structure’s functionality. For example, it will allow you to add new power outlets to give way for more appliances. With enough power outlets in a room, you can do away with extension wires. It will also allow you to install power outlets equipped with an on and off switch to help you protect your appliances from power surges.  

Rewiring your property also increases power capacity, so it meets the current demands of your household. Additionally, replacing or upgrading residential electrical wiring helps with the following:    

  • Rewiring allows you to add dedicated circuits that can stabilise the system.
  • New wiring systems usually include ground fault circuit interrupters. These are essential in preventing electrocution and other damages in bathrooms, kitchens, and outdoor areas around the house.
