Tree-heavy suburbs — Wahroonga, Killara, Pymble, Hunters Hill, Lane Cove — see the highest rate of overhead consumer mains damage in metro Sydney. East-coast lows and storm-driven branches account for hundreds of point-of-attachment and service-mains callouts every storm season.

On the leafy North Shore, big gardens often run long outdoor lighting and automation runs that fail at switches, sensors or low-voltage transformers rather than the globe. With the strong data and automation demand around Chatswood, we sort whether it's the light, the controller or the cabling underneath.

⚠ Stop — Call Immediately if You Notice Any of These:
  • A burning smell from any outdoor fitting
  • Visible water dripping from a fitting
  • Soot, char, or melting on any fitting
  • Sparks visible from a fitting
  • A fitting that is hot to touch
  • Tingles from any outdoor metalwork — fence, rail, gate, BBQ
  • An RCD that trips when outdoor lights switch on
  • A buzzing or crackling sound from any fitting

About Why Are My Outdoor Lights Not Working?

Outdoor lights fail most often because of a failed photocell or PIR sensor, water ingress into a fitting, a tripped RCD, or a perished cable. Water inside a fitting or a damaged cable is a genuine shock and fire hazard — if your lights are intermittent or your RCD keeps tripping, call 0433 462 902 immediately or book a same-day diagnostic.

Sydney’s coastal suburbs — Bondi, Coogee, Manly, Cronulla, Avalon — see salt-driven corrosion destroy fittings and cable sheaths years faster than inland properties. Outdoor circuits also run the longest cable runs in most homes, with the most intermittent switching and weatherproof seals to maintain, which is why they appear disproportionately in our Sydney callouts. Sydney Electrical Service is dispatched 24/7 across every metropolitan suburb.

What to Do Right Now in Hornsby

  1. Try the manual switch (if any) to confirm power is reaching the circuit.
  2. Check the switchboard for tripped breakers or RCDs on outdoor circuits.
  3. Reset any tripped device once. If it won't hold, leave it OFF and call us.
  4. For sensor-controlled lights, cover the photocell to simulate darkness and see if lights activate.
  5. For PIR motion lights, walk through the detection zone in low light to test.
  6. Inspect each fitting visually (during daylight) for water, damage, soot, or insect ingress.
  7. Try replacing the bulb in accessible fittings. LED retrofit bulbs need to match the fitting's voltage and driver.
  8. Photograph any damaged fittings for our diagnostic dispatch.
  9. For total circuit failure with no obvious bulb cause, book a Level 2 electrician.

Electrical work in Hornsby

Hornsby's housing is a real mixed bag, and the wiring tells the story. You've got pockets of Federation-era and older character homes alongside the streets of 1960s-to-1990s brick-veneer houses that dominate the area, sitting on big leafy blocks backing onto bushland. The older stock is where we see tired switchboards with ceramic rebewireable fuses, aged rubber or early PVC cabling, and no RCD safety switches, all of which are worth bringing up to current standards. On the bushland fringe, where so much of Hornsby sits, neat cabling, sound switchboards and properly rated circuits matter even more, especially for anyone running pumps, sheds or detached studios down the back.

Closer to the station and through Waitara, the newer R3/R4 strata blocks bring their own work: common-property switchboards, sub-metering and three-phase supply for lifts and shared services. Bigger renovated and knock-down-rebuild homes often need a three-phase upgrade and a board rebuild to handle ducted air-con, induction cooktops and EV chargers. As a Level 2 ASP working on the Ausgrid network, we handle the connection side too: consumer mains, point-of-attachment and metering work that a standard electrician can't legally touch.

Common Questions

The most likely cause is a failed photocell or PIR sensor — both have finite service lives, particularly in coastal Sydney where salt air shortens them. Replacement is straightforward but requires a licensed electrician.
The bulb is fine but the sensor has failed in the "always on" or "always off" position, depending on the model. Some sensors also have user-adjustable sensitivity and timeout that may have drifted. We can test, recalibrate, or replace as needed.
Sometimes — if the fault was transient water ingress that has dried out. More often, water has reached terminations and corrosion has begun. Inspecting fittings during daylight and replacing damaged seals is the right approach.
Many low-voltage garden lights run on 12 V or 24 V for safety in the wet. The transformer steps mains 230 V down to the lower voltage. Transformers do fail — typically with a buzzing or hot housing and lights that flicker or cut out.

From sub-$200 outlet repairs to $50,000 multi-storey switchboard-and-consumer-mains rebuilds, we bring the same Level 2 ASP capability to every North Shore job. Federation residence owners get the same standard of work as Chatswood high-rise strata committees.
