Northern Beaches homes face a combination of severe coastal corrosion, horizontal-rain storm exposure, and weatherboard-cottage heritage that drives the typical electrical fault patterns we attend across Manly, Dee Why, Avalon, Palm Beach, Mona Vale, and surrounding suburbs.

⚠ 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 Mona Vale

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

Electrical work in Mona Vale

Salt-affected switchboard contacts present as nuisance tripping that worsens through summer — warm/humid conditions accelerate the chemistry of the corrosion. Many Northern Beaches "intermittent breaker tripping" callouts trace to salt-corroded contact surfaces.

Common Questions

Why don't my outdoor sensor lights come on at night anymore?

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 lights work but the sensor doesn't activate. What's wrong?

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.

My outdoor lights stopped after the storm. Will they come back?

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.

Why do my garden lights need a transformer?

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.

Why Mona Vale Residents Choose Us

Salt-air corrosion isn't a hypothetical for the Northern Beaches — it's the underlying cause of about half of our local fault diagnoses. We replace tired outdoor outlets, switchboard contacts, and overhead service-mains terminations significantly sooner than equivalent inland installations.
