Mitcham's housing stock covers more eras than most suburbs we work in, and each era brings its own electrical problems. On the northern side of Mitcham Road, near the station and around Halliday Park and Simpson Park, the streetscape is older inter-war cottages and California bungalows — some of them still running the original wiring. Further east and south the housing shifts to post-war brick veneer from the 1950s and 60s, then to the 1970s and 80s brick-veneer profile that covers most of the quieter eastern streets. Layered across all of it, over the past decade or so, a wave of townhouse and duplex developments has replaced tired originals on the wider blocks — particularly near the rail corridor and along Mitcham Road.
Each of those building phases wires differently, and each one ages differently too.
The older homes near Mitcham station
The inter-war homes on the northern side of Mitcham station are the most demanding electrical work in the suburb. The oldest of them were wired with knob-and-tube — a system that uses no earth conductor and relies on rubberised cloth insulation that hardens and cracks with age. There is no safe way to extend or modify a knob-and-tube installation; the right answer is a full rewire. We decommission the original runs in the walls (pulling them is a demolition job; leaving them capped and dead avoids that) and replace the system with twin-and-earth TPS cable, modern junction boxes, and a fully RCD-protected switchboard. The work is more involved than a 70s veneer rewire, but the result is a house that's safe for another fifty years. After Mitcham station's recent level-crossing removal and the associated development along the rail corridor, a number of these homes have also been renovated or extended — and that's invariably when the wiring problem surfaces, because the renovation opens the walls.
The elevated rail section that replaced the old level crossing at Mitcham has also brought new commercial and mixed-use development to the Mitcham Road station precinct, and we've done electrical fit-out work on several of the newer tenancies there.
Post-war brick and the switchboard problem
The 1950s and 60s homes between Mitcham Road and Canterbury Road — the belt of post-war brick that forms most of the suburb's middle — have a different profile. Wiring from that era is generally TPS but often undersized by today's standards, and the original switchboards carry ceramic rewirable fuses with no RCD protection whatsoever. A house in this category running ducted heating, two split systems, an induction cooktop and an EV charger is asking too much of both the board and the original circuits. We replace the board, add RCBOs, and often run at least one or two new dedicated circuits at the same time — for the charger, or the cooktop, or the air conditioner that was retro-fitted to a circuit it was never designed to carry.
New townhouses and the rough-in stage
The townhouse and duplex developments replacing older Mitcham properties on the wider blocks need new electrical installations from scratch, and the best time to get us involved is at frame stage — before plaster, before joinery. We work with the builder during framing to run conduit, set GPO and light-point positions, and locate the switchboard. Getting circuit layout right at rough-in saves opening walls later and means the joinery and fittings land where they're meant to. We do this regularly across the new Mitcham townhouse stock and the coordination with carpenters and plasterers is familiar territory.
A five-minute run from the workshop
Our workshop is in Nunawading, five minutes west on Whitehorse Road. For an urgent fault — a board that trips and won't reset, no power on a circuit — we're in Mitcham quickly. Every prescribed job is finished with a Certificate of Electrical Safety lodged with Energy Safe Victoria and a workmanship guarantee on parts and labour.
About Mitcham
Mitcham sits in Whitehorse City Council, bounded roughly by Whitehorse Road to the north and the Belgrave rail line to the south. Mitcham station, where the level crossing was recently replaced by elevated rail as part of the state government's level-crossing removal program, sits near the centre of the suburb and marks the divide between the older inter-war housing stock to the north — around Halliday Park and Simpson Park — and the post-war brick veneer that dominates to the south and east toward Canterbury Road. Mitcham Road shops form the suburb's main local retail strip. Townhouse and unit development over the last decade has added a layer of newer dual-occupancy wiring to the original housing stock, so two very different electrical profiles routinely appear on the same street. Common jobs in Mitcham include rewires of pre-war homes with degraded original wiring, switchboard replacements in pre-1980 homes running ceramic fuses, smoke alarm compliance upgrades triggered by property sales, and EV charger installations for households along the rail corridor.
