Watch Out for These 5 Red Flags of Bad Wiring in Your NZ Home
Bad wiring can be hard to spot. Many New Zealand homeowners don't know about the dangers lurking in their walls—until it's too late. Even if you live in an old house or just moved into a fixed-up home electrical problems can pop up out of nowhere putting your family and property at risk.
At Mako Electrical, we've seen how small signs of wiring problems can turn into big safety threats. This blog aims to help you spot electrical dangers: we'll show you five key warning signs that might mean something's wrong with your home's electrical system—and what you should do about it.
1. Flickering or Dimming Lights: Not Just a Bother
Flickering or dimming lights often signal faulty wiring, yet many people ignore them. When your lights dim as you use appliances or flicker for no reason, you might have:
Loose wiring connections
An overloaded circuit
Worn-out insulation or corrosion
This issue goes beyond being a simple annoyance—it shows your wiring can't handle your home's electrical load . If you don't address it, your wiring could overheat and start an electrical fire. Frequent occurrences of this problem mean it's time to call Mako Electrical for an electrical safety check to find the root cause before things get worse.
2. Burning Smell or Discolored Power Points: Take Action Now
A constant burning odor—when you use a specific outlet or appliance—raises serious concerns. It often indicates that wire insulation has melted creating an immediate fire hazard. You might also notice:
Brown or black marks around outlets
Switches or power points that feel hot to touch
Don't ignore this smell or think it will disappear. Switch off the power at the switchboard and call a certified electrician right away. At Mako Electrical, our team responds to urgent electrical problems across Nelson and the surrounding area.
3. Circuit Breakers Trip Often: Your House Needs Attention
Your circuit breakers protect your home by cutting power when the system overloads. But frequent tripping—even when you're not using many appliances—might point to bigger issues such as:
Old wiring that can't handle today's power needs
Damaged wiring causing short circuits
Faulty appliances that draw too much power
Resetting your breaker doesn't solve the problem—it just puts it off. If your switchboard keeps tripping, you should get an expert to check it out. You might need to upgrade your switchboard or rewire parts of your house. See how Mako Electrical handles switchboard upgrades to keep your home safe and working well.
4. Buzzing or Crackling Sounds: Wiring Shouldn't Make Noise
Electricity doesn't make noise when it flows . Buzzing, crackling, or sizzling sounds from outlets light fixtures, or inside walls point to serious wire problems:
Sparks jumping between loose connections
Damage from pests, aging, or water
Poor grounding
These noises often mean wires are about to fail. Don't wait for smoke—these issues can cause bad accidents. Mako Electrical offers complete checks and problem-finding services to spot hidden dangers in your wiring.
5. Dead or Sparking Outlets: Warning Signs of Bad Circuits
When an outlet quits working or throws sparks as you plug something in, you should get it examined. Sparking might point to:
A short circuit inside the outlet
Damaged wires behind the wall
Water getting in and causing unsafe conditions
Outlets that don't work at all might mean a dead wire or a bigger issue within the circuit. You should never ignore these warning signs. For homes in the Nelson and Tasman regions, Mako Electrical's residential rewiring service can help make every socket in your home safe and functional again.
Why Faulty Wiring Is a Serious Problem in NZ Homes
In many areas of New Zealand—places with older houses—the electrical systems remain outdated. Some residences continue to use rubber or cloth-insulated wires, which break down as time passes. Even built homes face risks if unqualified workers carried out renovations or if builders cut corners during construction.
Faulty wiring creates several risks for homes:
Fires caused by electrical issues
Injuries from electric shocks
Harm to household appliances
Problems with insurance (defective wiring might invalidate coverage)
Homeowners who know how to spot the early signs of electrical dangers can prevent expensive repairs and keep their families safe.
Steps You Can Take to Ensure Safety
Don't overlook strange odors, noises, or actions from your electrical setup.
Stick to a consistent schedule to inspect your electrical system in older properties.
Bring in skilled nearby electricians such as Mako Electrical to install, fix, and rewire.
Think about upgrading to new safer setups like RCD protection and fresh switchboards.
Avoid DIY electrical work at all costs—it's against the law and risky in New Zealand.
