7 signs your home may need rewiring

2. Lights flicker or dim under load

Lights dipping when the oven, aircon or washing machine starts usually points to undersized circuits, loose connections, or too much sitting on one circuit. Occasional flicker in one fitting is often just the fitting. Consistent dimming across the house is a wiring issue.

3. Warm outlets, warm switches or discoloured faceplates

A power point should never be warm to touch. Heat means resistance, and resistance at a connection means the connection is failing. Brown or yellow staining around a faceplate is the same story at a later stage.

This one should not wait. Stop using the point and get it looked at.

4. Any burning smell

A faint fishy or acrid plastic smell near a point, switch or the board is overheating insulation. If you can smell it, turn that circuit off at the board and call an electrician. There is no safe version of ignoring it.

5. Circuits keep tripping and the cause keeps moving

One appliance tripping a circuit is an appliance problem. Repeated tripping that a fault find traces to a different spot each time usually means the cable insulation is failing generally, not in one place.

If you are at the start of this, work through why your safety switch keeps tripping first. It will tell you whether you are chasing an appliance or something structural.

6. Two pin points, too few points, and no earthing

Old two pin outlets, one power point per room, double adaptors on every wall, and lighting circuits with no earth are all signs the installation predates how the house is used now. Extension leads running permanently through a house are a fair signal that the wiring never caught up with the furniture.

7. A renovation has opened up what is behind the walls

Renovations are where old wiring gets exposed: junctions buried in ceilings, unprotected cable stapled to framing, circuits extended by a past owner, or cable running straight through insulation. It is also the cheapest moment to fix it, because access is already open.

If the walls and ceilings are coming off anyway, that is the time to get a scope for home rewiring rather than discovering it afterwards.

Full rewire or partial?

It is rarely all or nothing. Testing shows which circuits are still sound, and in many homes the kitchen and bathroom have already been redone in a past renovation. That often leaves the original lighting and power circuits and the switchboard as the real scope.

The board is almost always part of the conversation. New circuits need somewhere to land, and a rewire into an old fuse board leaves the least safe part of the system untouched. See how to tell if your switchboard needs an upgrade for what we look at.

When to book an inspection

An inspection is the sensible first step before committing to anything. It is also worth doing at predictable moments rather than waiting for a fault.

• Before buying, or soon after moving into an older home
• Before a renovation, so wiring is designed in rather than patched around
• When any of the warning signs above appear
• If the property is being rented out and has no recent electrical record

What the work looks like in practice

We stage a rewire so the house stays liveable, keeping power on to areas not being worked on where we can. Every new circuit is tested, labelled and certified at completion, and you get a written scope before anything starts. If a quote is one line with no detail on circuits, points or making good, ask for more.

A home electrical inspection is usually where this begins. It also picks up the cheaper safety items at the same time, like smoke alarms that are past their ten year replacement date.

Older housing stock is common across Sutherland, Caringbah and the St George suburbs, so this is work we do regularly rather than occasionally.
