One short peninsula holds 1870s terraces, interwar flats built for harbour workers, and a 25-storey Seidler tower. Three completely different buildings, three completely different electrical jobs, often in the same street.
Pricing agreed before we start. We usually reply the same day.
McMahons Point held 2,315 people at the last census, on a peninsula you can walk end to end in fifteen minutes. What makes it interesting electrically is not the size, it is the mix.
Nearly a quarter of the dwellings here are terraces and semis, roughly double the New South Wales share, and most of those are the Victorian terraces that went up after the peninsula was subdivided through the 1870s. Another 63 per cent are flats: the interwar blocks built for the harbour workers of a suburb that was, for most of a century, an industrial waterfront with slipways at both bays, and the later towers, of which Blues Point Tower is the famous one. Separate houses are just 13 per cent.
Each of the three has its own failure modes. The terraces have solid walls, no cavities and, where nobody has intervened, wiring from eras that should not still be in service. The interwar flats have the common property problems of any older block, with the rising main the quiet one. The tower and the newer buildings are strata machines, where the question is usually whose asset the fault sits in.
And more than half the suburb rents, which shapes how the work actually arrives: through agents, on behalf of owners, with a tenant at home. We are set up for exactly that triangle.
The one thing this suburb barely has is the ordinary detached house on a quarter-acre. Which is why an electrician who mostly does those tends to quote strangely here.
A Victorian terrace is solid brick from footings to roof. There is no wall cavity to drop a cable through, which changes how every job in one should be planned and priced.

What it means: the roof void and the front subfloor are the highways, and they are genuinely workable. Everything between them is the hard part, because a switch or power point below ceiling height sits at the bottom of a chase cut into solid brick, made good and repainted afterwards. A terrace rewire is priced well when somebody has counted those drops beforehand, and priced badly when they are discovered one at a time with the job underway.
This is also why staging works so well in a terrace. The roof void feeds the lighting and the upper floor, the subfloor feeds the ground floor, and the two halves can be done as separate visits with the house liveable in between. The rear skillion, being later and lighter construction, is usually where the kitchen loads land, and it is the most forgiving part of the building to work in.
What the age of these houses means for the wiring itself, era by era, is on our rewiring page. The short version for an unrenovated terrace is that cloth-and-rubber insulation from the early decades has no business carrying current in 2026, and the tell is at the switchboard: ceramic fuses and no test buttons anywhere.
Between the terraces, the flats, the tower and the tenancies, almost nothing here is a standard suburban callout.
The terraces have no cavities, so every point below ceiling height is a chase cut into brick. The number of drops, not the number of fittings, is what separates one quote from another.
We count them before pricing and design to minimise them: feeding from the subfloor, using the skillion, and putting the hard runs where the making good is least visible.
Blues Point Tower holds 144 apartments, and with the Harbour Master and the newer buildings, big-strata work is a real share of this suburb: risers, meter rooms, common area lighting and the boundary between the building's assets and yours.
Who owns which fault is settled law rather than opinion, and we put our finding in writing. The rules are on our Southern Sydney page and apply here identically.
The blocks built for harbour workers in the 1920s and 30s have usually had their apartments modernised and their common property left alone, which means the rising main feeding every meter can be approaching a century old.
The symptoms show up inside flats while the cause sits in the stairwell. We wrote the full anatomy up on our Kirribilli page, and the same buildings line these streets.
About 52 per cent of households here rent, so much of our work arrives through managing agents on behalf of owners, with a tenant at home. That triangle only works if someone closes the loop.
So we schedule directly with the tenant, do the work, and report back to the agent with photos and the certificate the same day. Nobody has to chase anybody, which is the entire trick.
Sheltered water throws far less salt into the air than surf, so the peninsula sits well below any ocean suburb on the corrosivity scale. Exposed metal on the Blues Point end still earns proper fittings and fixings.
The full story of what distance from which water does to hardware is on our Northern Beaches page.
The peninsula hangs off Blues Point Road, the streets are narrow and permit-parked, and several of the terrace rows are reached on foot. Materials get carried, not wheeled.
We plan for that: scope properly, bring everything once, and batch whatever else needs doing into the same visit. It is cheaper for you and saner for us.
McMahons Point has been a conservation area under North Sydney's planning controls since 2001, the outcome of a preservation fight this suburb ran for decades. The council describes conservation controls as concentrating on the external envelope of buildings, gardens and site structures, so work inside your own walls, including rewiring and switchboard replacement, is generally maintenance rather than development.
What needs checking is anything that changes how a building presents to the street: meter box positions, visible conduit, condensers on facades or balconies, external lighting, anything on a front roof slope. We raise those before quoting. In the apartment buildings, the owners corporation has a say over anything touching common property as well, and getting that sequence right is most of the administration.
Inside, our position is simple: period faces, modern guts. Reproduction switches and roses where you want the look, and behind them a fully modern, certified installation, because cloth-insulated cable from the terrace era has no business carrying current at this age.
Everything is certified. We lodge a Certificate of Compliance for Electrical Work within 7 days of testing, which since 1 July 2026 goes through the BCNSW eCert portal. None of the planning information here is legal or planning advice; anything specific to your building should be confirmed with Council or your strata manager.
Ferryman's grant, industrial waterfront, near-demolition, conservation area. Every phase left buildings behind, and the buildings kept their wiring habits.
Billy Blue, the Jamaican-born ferryman, receives a land grant at the southern tip of the peninsula, and Blues Point carries his name still. Blues Point Road is gazetted as a thoroughfare in 1839, and it remains the spine everything else hangs off.
Michael McMahon, an Irish brush and comb manufacturer who arrived in 1848, builds his home on the point and gives the suburb its name. As a local politician he campaigns for fresh water and reliable ferries, and by 1890 he is mayor of the borough.
The peninsula is subdivided and the Victorian terraces and workers' cottages fill the streets. This is the housing stock the conservation area now protects, and the oldest building fabric we work inside: solid brick, no cavities, and original ceilings worth planning around.
Boatbuilding and slipways line both bays, with Neptune Engineering at Berrys Bay growing into one of the largest operations on the harbour and four generations of one family working its slips. The tram arrives in 1909, and the interwar flats go up for the workforce. Buses replace the tram in 1933.
The postwar planning scheme zones the peninsula industrial, and Harry Seidler proposes replacing it wholesale with dozens of apartment towers. Residents and the council fight it, and in the end exactly one piece is built: Blues Point Tower, finished in 1962, 25 storeys and 144 apartments on the point. It divides opinion to this day, and it has been on the local heritage register since 1993.
Neptune Engineering leaves Berrys Bay and the industrial era ends. The waterfront becomes parkland and the terraces, once workers' housing beside the slips, are restored one by one.
The preservation the residents fought for in the 1950s is formalised: McMahons Point becomes a conservation area under North Sydney's planning controls. The buildings you see are, broadly, the buildings there will be, which is exactly why the wiring inside them matters so much.
Not a generic service list. This is genuinely what the phone rings about in this postcode.
Roof void and subfloor as the highways, drops counted before the price, plasterwork planned around rather than through. Done in stages so the house stays liveable.
Electrical rewiringCeramic fuses in a terrace hallway or a 1930s meter room mean nothing in the building is protecting people. Modern RCBOs fix that in a day and give new circuits somewhere to live.
Switchboard upgradesRising mains in the interwar blocks, common area lighting, meter rooms, and written findings a committee or strata manager can act on without a second opinion.
Strata electricianHigh ceilings, roses and cornices that predate downlights by a century. Getting good light into a Victorian room without carving up the reason you bought it.
Lighting installationMasonry that defeats Wi-Fi and walls you cannot fish a cable down. Access points fed through the same planned routes as the power, by registered cablers.
Data cablingTerraces still on their original supply, and buildings that have outgrown theirs. The network side is Level 2 work, and we hold the accreditation ourselves.
Consumer mains & Level 2Everything hangs off Blues Point Road, and nothing is more than a few minutes from the wharf.
Because the price is not really in the fittings, it is in the vertical drops. A terrace has solid brick walls with no cavity, so every switch and power point below ceiling level sits at the bottom of a chase cut into brick, made good and repainted afterwards. Two quotes for the same house can differ simply because one design needs eight drops and the other needs fourteen, or because one electrician counted them before pricing and the other is planning to find out on the job. We count them first, and we will show you where every one lands.
Yes, with planning rather than heroics. The horizontal runs go through the roof void and the front subfloor, which leaves the original ceilings and cornices alone. The drops are cut where they do least harm, chased once, and made good properly. Where a wall carries something genuinely irreplaceable there are usually alternatives, like feeding from below or using the rear skillion, which is later construction and far more forgiving. What we do not do is surface-run conduit through a Victorian front room and call it done.
Inside your own walls, generally not. McMahons Point has been a conservation area under North Sydney's planning controls since 2001, and the council describes those controls as focused on the external envelope of buildings, gardens and site structures. Rewiring, new circuits and a switchboard swap are maintenance. What needs checking is anything visible from outside: a meter box on a street-facing wall, external conduit, a condenser on a balcony or facade, or anything on a front roof slope. We flag those before quoting, and in an apartment building the owners corporation has a say as well.
The same rule as any New South Wales strata scheme: what serves more than one lot is common property and belongs to the owners corporation, and what serves only your lot and sits inside it is yours. In a 144-apartment tower that line matters, because the risers, the meter rooms and the main switchboard are the building's, while the board and circuits inside your apartment are yours. We find the fault, then put in writing which side of the line it landed on. The full explanation is on our Southern Sydney page and applies here identically.
All three, in the order the law arranges them. The work is authorised by the owner or their managing agent, and we are used to that triangle: the tenant reports it, the agent approves it, we schedule directly with whoever is home and report back with photos and the certificate. About 52 per cent of McMahons Point households rent, so this is most of what a weekday here looks like, and the thing that matters is closing the loop fast enough that nobody has to chase anyone.
A mild one rather than a beach one. Airborne salt comes overwhelmingly from breaking surf, and sheltered harbour water produces far less of it, so McMahons Point sits well below an ocean suburb on the Australian corrosivity scale. Exposed harbour-facing metalwork still deserves decent fittings and fixings, especially on the Blues Point end, but it does not need the full marine specification. The detail is on our Northern Beaches page.
Yes, and it is a distinction worth making. The look of a period interior comes from the fittings, the roses and the switches, and there are excellent reproduction ranges with modern guts. The wiring behind them should be nothing of the sort. Cloth-insulated cable from the terrace era is a genuine hazard at this age, and the right result is a completely modern, certified installation wearing period clothes. We do the wiring properly and will happily fit whatever face you have fallen for.
Attending your job is a chargeable callout. We confirm what it costs when you book, and the price for the work itself is agreed before we start, so there are no surprises on the invoice.
Based in Castlecrag, so the lower North Shore is home ground and the peninsula is a short run.
