Lightning Strike Damage? What Survived Isn't Always Safe — Get It Tested
A lightning strike — direct or nearby — drives thousands of volts through wiring built for 230. Some damage announces itself immediately; plenty hides in cooked insulation and half-killed appliances that fail weeks later. High Demand Electrical provides full post-strike inspection and repairs across Sydney, 24/7.

After a Strike: What You Might Be Seeing
Lightning damage ranges from obvious to invisible. Any of these after a storm means the strike found your electrical system — call 0402 559 777 for a post-strike inspection.
- Power out, breakers tripped, or the main switch won't reset since the storm.
- Multiple appliances dead at once — the classic surge signature.
- Burning smells, scorch marks at outlets, or a damaged meter box or antenna.
- Everything seems fine — but the strike was close. Hidden insulation damage is exactly how post-strike fires start.

Our Post-Strike Inspection and Repair
Lightning work is systematic — the surge travelled everywhere the wiring goes, so the inspection has to as well.
Make safe and isolate damage
Burnt circuits and damaged boards isolated so the rest of the property can run while we work.
Whole-installation testing
Insulation resistance on every circuit — the test that finds surge-cooked cable before it fails behind a wall.
Switchboard and protection check
Breakers and RCDs that carried the surge are tested to standard — they can be silently damaged and fail to protect next time.
Repair and replace
Damaged wiring, boards, meter equipment and connections repaired — including the Level 2 network-side work.
Surge protection installed
Board-level surge diverters fitted so the next strike hits a device designed for it — not your appliances.
How Lightning Damages Electrical Systems
Understanding the damage patterns is why our post-strike inspections find what quick look-overs miss.
Direct Strike Damage
Strikes to the building or service line explode conductors, burn boards and scorch meter equipment — dramatic and dangerous.
Induced Surges From Nearby Strikes
A strike hundreds of metres away induces damaging voltage in your wiring — the most common and most underestimated case.
Surges Down the Service Line
Strikes on the network arrive through your connection — meter, board and appliances take the hit in order.
Cooked Cable Insulation
Surge heating degrades insulation without visible damage — failures surface weeks later as trips, shorts and fires.
Silently Damaged Protection Devices
Breakers and RCDs that carried a surge may no longer trip to spec — we test rather than trust.
Appliance and Electronics Losses
From dead TVs to half-damaged fridges that limp on — we document losses for your insurance claim.

Lightning Claims, Properly Documented
Lightning and surge damage are standard insurance events — and thorough documentation is what separates paid claims from disputed ones.
- Written cause assessment linking damage to the strike event
- Photographed damage record across the installation
- Insulation test results proving hidden wiring damage
- Itemised repair and replacement quote for the assessor
- Appliance damage inventory for contents claims
- Compliance certification on completed repairs

FAQs
Lightning struck nearby and now several appliances are dead. What happened?
A nearby strike induced a voltage surge in your wiring — it doesn't need to hit your house to destroy electronics. Beyond the dead appliances, the same surge may have damaged wiring insulation and protection devices invisibly, so a full inspection is worth it. Call 0402 559 777.
Everything works after the strike. Should I still get an inspection?
If the strike was close or came through your service, yes. Surge-damaged insulation and half-damaged protection devices are invisible until they fail — and post-strike electrical fires typically start days or weeks later. An insulation test settles it definitively.
Will surge protection stop this happening again?
Board-level surge diverters absorb the large surges that arrive through your supply and drastically reduce appliance and wiring damage from future strikes. No device makes a direct hit consequence-free, but protected homes fare dramatically better. We install them as part of post-strike repairs — quoted upfront.
