The Bureau kept naming this the wettest suburb in Sydney, and most of it is wired overhead, through its own magnificent trees. Around here, the weather is an electrical condition.
Pricing agreed before we start. We usually reply the same day.
The name is said to mean high hill, and the hill is the whole story. Turramurra sits about 179 metres up on the Ku-ring-gai ridge, high enough that weather coming off the coast drops its rain here first. The Bureau of Meteorology named it the wettest suburb in Sydney in 2007, 2008, 2010, 2011, 2012 and 2014, and in 2010 the gauge on Kissing Point Road recorded 1,424.8 millimetres against Observatory Hill's 1,153.8. Roughly a quarter more rain than the city, most years.
The second thing is the trees. This is one of the most heavily canopied suburbs in Sydney, with remnant blue gum and turpentine forest surviving in Sheldon Forest on its edge, and street after street of gardens grown tall over a century. It is most of why people live here.
Put those together with the third thing, which is that this is a suburb of houses, 68 per cent of them separate houses on generous blocks, mostly supplied overhead, and you get the local electrical condition: long spans running from street poles through canopy to private poles and Federation-era homes, in the suburb where it rains hardest.
That is why the work here has a season. After every serious storm the phone runs hot with the same handful of faults, and the rest of the year is spent, sensibly, on the things that stop those calls: sound poles, clear spans, dry fittings and switchboards that have joined the modern era.
Most Turramurra houses are fed the same way: a span from the street, through trees, often via a private pole, to the house. Every part of that run has an owner, and most of it is you.

What it means: Ausgrid's responsibility ends at the connection point, and everything past it, the span, the private pole, the board and every garden circuit, is the property owner's to maintain. The four marked points are where this suburb's weather actually does its damage, and three of the four are invisible from the ground until they fail. A ten-minute look at all four, every few years, is the cheapest electrical work you will ever buy here.
These are the faults Turramurra's weather actually produces, what each one means, and which ones cannot wait.
The safety switch trips whenever it rains
Water is reaching a conductor somewhere, almost always outside: an aged seal on a garden light, a damp external power point, moisture in a shed run. The fault is real even though it dries up by lunchtime.
Diagnosable in one visit by testing circuit by circuit. Resetting it every morning is not a plan.
Power out, but only at your place
If the street is dark it is Ausgrid's outage. If it is just you, the damage is probably on your side: the span, the private pole or the board, and a private electrician restores it, not the network.
We make safe first, then put in plain terms which side of the connection point the problem sits on.
Lights flicker when the wind gets up
Wind-synchronised flicker means a connection is moving: a rub point where the span meets the house, or a loose termination. Moving connections arc, and arcing connections eventually become a midnight callout.
A short diagnostic visit while it is still an appointment rather than an emergency.
A branch has come down across the line
Stay well clear and treat every line as live, including a span lying on the ground or resting in a tree. Nothing about a fallen conductor is safe to test by hand.
Network lines are Ausgrid's emergency. Your own span and pole are ours, made safe first and repaired properly second.
On blocks this size the connection point is often well short of the house, which makes the private pole, the span and everything beyond them the property owner's assets. Keeping vegetation clear of your own line is part of that, and on gardens this established it is the part that gets away from people.
Ausgrid inspects private assets from time to time. If a defect notice arrives, the Electricity Supply Act allows 30 days to respond, and supply can be disconnected if nothing is done within 60. A rotted pole or a perished span found by an inspector is the same job as one found by you, minus the deadline pressure, which is a good argument for finding it yourself.
Work at the point of supply, pole replacements, service line repairs, undergrounding a span, or a supply upgrade, is Level 2 work. We hold the accreditation, so a defect notice or a storm repair is one call and one crew rather than a referral chain.
Everything is certified: we lodge a Certificate of Compliance for Electrical Work within 7 days of testing, through the BCNSW eCert portal since 1 July 2026.
The other consequence of generous blocks is that everything electrical outside the house is a long way from the switchboard. A run to a front gate, a rear studio, a pool shed or the end of a driveway is a voltage drop calculation before it is anything else, and cable sized for the length is the difference between garden lighting that is set and forget, and the circuit that sulks every winter.
Outside fittings here earn their keep or fail fast. Anything in the garden lives under drip lines and leaf litter in the wettest suburb in Sydney, so we fit gear that seals properly, at depths and in conduit that keep water out for decades, and we put outdoor circuits on their own protection so a wet garden light cannot darken the kitchen.
The houses themselves are the third pleasure of working here. Federation and California bungalow stock, some of it with wiring generations younger than the walls, some of it overdue. Where original fabric matters we plan cable routes around it, and our rewiring page covers what each era of wiring means. The short test anyone can do: open the switchboard, and if you see ceramic fuses and no test buttons, the house is running on borrowed protection.
Not a generic service list. This is what actually comes in from this postcode.
Defect notices, rotted poles, storm-damaged spans and undergrounding through the trees. Level 2 work at the point of supply, done by us rather than referred out.
Consumer mains & Level 2Ceramic fuses still turn up in Federation hallways here. Modern RCBOs mean a wet garden circuit trips one breaker instead of gambling the house, and every circuit gets real protection.
Switchboard upgradesLong runs sized for the distance, fittings sealed for the rainfall, buried properly and put on their own protection. Designed to disappear into the garden and stay working.
Outdoor lightingRoutes planned around original fabric, staged so you stay living there, and the eras of what might be in the walls explained before anyone lifts a floorboard.
Electrical rewiringOverhead supply through trees in a storm-prone suburb is the textbook case for a switchboard device, fitted while the board is open and checked after big events.
Surge protectionZones, bonding and safety switch protection for pools and spas, plus pump circuits run the full length of the garden and fittings chosen for a leafy, wet yard.
Pool electricianFrom the village and the station out to the reserves, and every long driveway between.
Because somewhere on the property, water is reaching a conductor, and the safety switch is doing exactly what it exists to do. The usual suspects in Turramurra are outdoor fittings whose seals have aged, garden lights with water sitting in them, damp in an external power point, or moisture tracking into a junction on a shed or gate run. The fault is real even though it dries out and disappears by lunchtime. We test circuit by circuit, find the one leaking to earth, and fix that rather than telling you to live with resetting it.
That pattern usually means the fault is on your side of the connection point rather than the network's. If the whole street is dark it is Ausgrid's outage. If it is just you, the likely candidates are your service line, your private pole, or the switchboard, and a private electrician rather than the network restores it. We make safe first, then tell you plainly which side of the line the damage sits on and what the fix is, because chasing the wrong organisation costs people days.
You are, if it stands on your side of the connection point, and a great many Turramurra blocks have one. That covers the pole itself, the span to the house, the fittings on top, and keeping vegetation clear of all of it. Ausgrid inspects from time to time, and if they find a defect the Electricity Supply Act gives you 30 days to respond; left uncorrected past 60 days, supply can be disconnected. Pole and line work at the point of supply needs Level 2 accreditation, which we hold, so a defect notice is one call rather than a hunt.
Often yes, by taking the run underground from the connection point, and on heavily treed blocks it is the permanent fix rather than the cosmetic one. It removes the branch risk, the rub points and most of the storm exposure in one job. It is trenching work with Level 2 consenting at the network end, so it is not the cheapest option, but it is the last time you think about that span. We quote it with the trench route walked and agreed first, because on an established garden the route matters as much as the cable.
Treat it as a warning rather than a quirk. Wind-synchronised flicker usually means a connection is moving: a worn point where the span rubs at the house, a loose termination at the board, or a tired joint in the service run. Moving connections arc, arcing makes heat, and heat is how these become a callout at midnight instead of an appointment. It is a short diagnostic visit to find, and usually a small repair once found.
They need honest wiring, which on Turramurra blocks means allowing for distance. A long run to a front gate or a back garden drops voltage, so cable is sized for the length rather than the load alone, buried at proper depth, and fed through fittings that keep water out for more than one winter. Done that way, garden lighting is set and forget. Done with whatever was on the roll, it becomes the circuit that trips every storm. Our outdoor lighting page covers the design side; the wiring side is where we are fussiest.
The house will outlive us all; the question is only what vintage of wiring is hiding in it. Many Ku-ring-gai houses have been rewired somewhere along the way, but where original or early wiring survives, insulation from that era is at the end of its life and lighting circuits often carry no earth. The tell is at the switchboard: ceramic fuses and no test buttons. Our rewiring page walks the eras in detail. In a heritage house we plan routes to protect original fabric, and stage the work so you stay living there.
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.
The upper North Shore is regular ground for us, ridge to river on both sides.
See the full list of locations we service. After a storm, call first and we will tell you honestly whether it is our job or Ausgrid's.
