Electric fence repairs in the Midvaal and Joburg South
Beeping, alarming in the rain, or dead after a storm? We find the fault and fix it.

Your fence is telling you something’s wrong
- The energiser beeps and won’t stop.
- The alarm goes off every time it rains.
- The fence clicks, but there’s no bite.
- It died after a storm or a long power cut.
Each one leaves a gap in your boundary tonight. Most are quick to fix once the fault is found.
We find the exact fault and fix the cause, not just the symptom
- We test every zone and walk the line to the spot.
- We fix broken strands, bad joints, cracked insulators and weak earthing.
- We repair or replace the energiser, with lightning protection.
- We replace a backup battery that no longer holds a charge.
Then we test every zone again and show you the readings.

What usually goes wrong, and what we do about it
| What you notice | What it usually is | What we do |
|---|---|---|
| Energiser beeping, alarm keeps going off | Low voltage on a zone: something touching the wires, a broken strand, an earth fault | Test each zone, find the spot, fix the cause |
| Alarm goes off when it rains | Plants on the strands, cracked insulators, a weak earth that shows when wet | Trim back, replace insulators, improve the earth |
| Clicks but no bite, low voltage | A short to earth, a broken joint, or a tired energiser | Track the short, redo joints, test the output |
| Energiser dead after a storm | Lightning or a surge | Repair or replace, fit diverters and surge protection |
| Fence dies in a power cut | The battery no longer holds a charge | Test and replace the battery |
| Keypad or remote won’t arm it | Flat remote, receiver or keypad fault | Recode or replace the remote, repair the keypad |
| Alarms when the power comes back | A fault shows once it’s on mains, or the battery is too low to start | Check the supply, battery and settings |
| Trips the earth leakage in the house | A fault in the energiser or its supply | Test both, then repair or replace |
A dead energiser: we’ll tell you honestly whether to repair or replace it
The energiser powers the fence and raises the alarm. A ten-year-old unit that’s been hit by lightning is usually not worth fixing.
A replacement comes with a SANS 60335-2-76 test certificate, sized to your fence, with a screen that shows which zone has the fault.
Certificates: a simple repair (a broken wire, new insulators) doesn’t need a new one. A new energiser counts as a change, so the fence needs a new electric fence certificate.
Highveld storms and power cuts are hard on fences, so we check both
- Lightning: a strike near a long fence line can send a surge into the energiser.
- Batteries: every power cut runs the battery down and charges it again. After a few years it can’t hold a charge, and the fence goes quiet a few hours into an outage. We test it on every call-out.
- 2G and 3G: those networks are being switched off (the national target is the end of 2027). Fence gateways on them will go quiet.
Not sure what’s wrong?
When patching costs more than fixing it properly, we’ll say so
If your fence alarms every week, the wires are rusting through, or the brackets are coming off the wall, patching it costs more over a year than fixing it properly. Sometimes the answer is a new energiser and new strands on the old brackets. Sometimes it’s a new fence, built to SANS 10222-3 and certified. You get both options in writing, with prices.
A maintenance plan stops most of these faults before they start.
Four checks you can do while you wait
Switch the energiser off at the keypad or remote first. Never touch the wires while the fence is on.
- Power: check the plug, the plug point and the breaker. If the mains light is off, it’s on battery and will go flat.
- The line: look for a branch, creeper or fallen wire touching the strands.
- Gates: a gate left open, or contacts that have moved, will set it off.
- The screen: most energisers show which zone has the fault. Photograph it and send it to us.
Questions
Questions people ask us
Why is my electric fence beeping?
The energiser is telling you it has found a fault. Usually the voltage on one zone has dropped because something is touching the wires, a strand has broken, or the earth is poor. Switch the fence off, look along it for branches or a fallen wire, and send us a photo of the energiser screen.
Why does my electric fence alarm keep going off when it rains?
Rain shows up weak spots. Plants touching the strands, cracked insulators and a poor earth all leak more current when they’re wet, so the voltage drops and the fence alarms. Trimming back helps. If it keeps happening, the insulators or the earthing need fixing.
Do I need a new COC after my fence is repaired?
Not for a simple repair, like a broken wire or new insulators. Replacing the energiser, or adding to or changing the fence, needs a new electric fence certificate. We can test the fence and issue it on the same visit.
