House rewiring
Period homes with cloth or rubber-insulated wiring brought up to AS/NZS 3000, in stages if needed.
Malvern is about four kilometres from our Hawthorn East workshop, usually a ten to fifteen minute run.
Malvern is a suburb of substantial Edwardian and interwar brick homes on generous blocks, and it renovates harder than almost anywhere else we work. That combination, old fabric under constant modification, is what defines the electrical work here.
The cable above the ceilings in a Malvern Edwardian is often the original, and rubber insulation of that age is brittle. It survives untouched and fails when disturbed, so the fault typically appears in the week after downlights go in, insulation is laid or a data cable is run. People connect it to the wrong cause because of the delay. If ceiling work is planned, have the existing cable assessed first.
These houses accumulate load: ducted heating and cooling, an induction cooktop, a wall oven, a second bathroom, underfloor heating, a charger in the garage. Each addition is reasonable on its own and each lands on the same board. Eventually there is no spare way and the consumer mains are carrying more than they were sized for. Checking both before the next stage, rather than after, is what keeps the cost proportionate.
The retail spine brings steady fitout and maintenance work, including exit and emergency lighting that has to be tested and logged on a schedule rather than when someone remembers.
Deep blocks mean garages, studios and pool plant at a distance from the board, on submains that were adequate for their original purpose. Length plus added load produces voltage drop, and the symptom is usually blamed on the appliance at the far end rather than the cable feeding it.
Toward the creek the ground is damper and subfloors hold moisture, which is where persistent safety switch tripping tends to originate. Old cable at subfloor junctions takes up moisture and the residual current device does exactly what it is designed to do. Testing the circuits properly beats fitting a second device.
Four kilometres from Hawthorn East, ten to fifteen minutes outside peak. Morning faults are normally attended the same day. For genuine emergencies we aim to be on site within two hours, and the line is answered 24 hours a day.

Ceramic fuses replaced with circuit breakers and safety switches, with capacity left for what you add next.
Downlights, pendants and outdoor lighting, replaced or run from scratch.
A written check of the board, the wiring and the safety switches, for a purchase, a rental or peace of mind.
Ceiling fans, bathroom exhausts and ducted extraction, wired and vented properly rather than into the roof space.
In an Edwardian Malvern house, yes, enough to check first. Cable of that age is brittle and installing downlights disturbs it, so a fault often shows up a week or two later. Assessing the affected part of the roof before cutting holes is far cheaper than chasing it afterwards.
Almost certainly moisture in old cable at subfloor junctions, which is common on the damper ground near Gardiners Creek. The device is working correctly. Replacing it does nothing because the fault is under the floor, and finding it requires testing circuit by circuit.
It depends on the board and the consumer mains behind it, which we check together. Most Malvern renovations add load in stages until there is nothing left, so knowing where you are before the next stage is the useful moment rather than after.
No, it is voltage drop on a long submain. The cable was sized for its original purpose and the load has grown since. The fix is a correctly sized submain, and it also stops the pump running hot and failing early.
Yes, installation and the six-monthly testing to AS 2293.2, with the log an auditor or insurer will ask for. The testing is the part sites most often miss, because the system sits unused until the day it matters.
Fastest way to get an answer is the phone. It is answered 24 hours a day, seven days.
