Fence alarm, broken wire repairs.
We diagnose and repair electric fence faults across Pretoria: broken and rusted wires, shorts to earth, recurring alarms, low voltage, batteries and energiser problems.

We fix electric fence faults
The timing of an alarm and the way the fence behaves can help narrow down the fault. A technician can test the system and confirm the cause.
Short to earth
A live wire may be touching vegetation, another wire, a metal support or another grounded object. The alarm may sound as soon as the fence is switched on.
Broken live wire
A cut wire, loose joint or damaged connection can interrupt the monitored circuit and trigger an alarm on systems configured to detect it.
Low battery
Some energisers report a low battery. A fence that stops working during a power outage may also need its backup battery or charging system checked.
Energiser fault
Power surges or other component failures can affect the energiser. Testing determines whether a repair or replacement makes sense.
Alarm when it rains
Moisture can expose cracked insulation, poor joints or contact between wires and supports.
Low fence voltage
Corrosion, poor connections, vegetation and other faults can reduce performance along the fence line.
Trouble-shooting guide.
| What you notice | Possible cause | Typical assessment |
|---|---|---|
| Alarm sounds immediately | Short to earth or broken monitored wire | Inspect wires, connections, supports and vegetation |
| Alarm sounds in wet weather | Damaged insulator or unwanted contact | Trace moisture-related contact points |
| Fence stops during a power outage | Battery or charging fault | Test the backup power system |
| Fence performance is low | Corrosion, poor connection or other line fault | Test sections of the fence and energiser |
These are possible causes, not a remote diagnosis. Avoid touching fence wires or opening energiser equipment while the system is operating.
Cost of repairs.
Repair price starts at R750 excluding parts. The original page describes this as covering fault finding and basic broken-wire repairs. Light vegetation clearing may be included; thicker clearing, replacement components, extensive rewiring and upgrades are assessed separately.
We locate the problem, explain what needs attention and quote for any additional work. Ask for the parts and labour to be shown clearly on your quotation.
Request an assessment ↗When small repairs are no longer enough.
Older or poor-quality wires can corrode and develop high-resistance connections. Repeated breaks, rusted clamps and persistent low performance may make a larger rewiring job more sensible than another isolated repair.
We assess the existing supports and fittings as well as the wire. A rewiring quote should identify what can be retained, what needs replacement and the planned wire material.
| Wire material | Listed size | Original page’s estimated lifespan |
|---|---|---|
| Stranded galvanised | 1.2 mm | 8–10 years |
| Solid galvanised | 2.2 mm | 10–15 years |
| Stranded aluminium | 1.6 mm | 10–15 years |
| Solid aluminium | 1.6 mm | 15–20 years |
| Stranded stainless steel | 1.2 mm | 15–20 years |
Actual life varies with location, material quality, installation and upkeep.
A clear path from fault to fix.
Describe it
Tell us the alarm behaviour, location and any visible damage.
Find the cause
We inspect and test the fence, connections, battery and energiser as relevant.
Agree on the work
We explain the repair and any replacement parts before additional work begins.
Test again
We check operation after the repair and explain what was fixed.
Reduce repeat faults.
Regular visual checks help you spot vegetation growing into the fence, loose wires, rusted fittings and damage before a fault becomes more disruptive.
Keep the fence route clear and arrange servicing if wires lose tension or an alarm returns. Battery condition matters if you rely on the system during power interruptions.

Before you book a repair.
Why does the alarm sound as soon as I switch on?
A short to earth, broken monitored wire or loose connection is possible. Testing confirms which part of the system is at fault.
Why does it alarm when it rains?
Moisture may reveal damaged insulation or an unwanted connection between a live wire and another surface.
Should I repair or rewire the fence?
A single isolated fault may need a small repair. Widespread corrosion or repeat failures can make rewiring the better long-term option.
Are replacement parts included in R750?
No. The published starting price excludes parts. The final quote depends on the diagnosis and required components.
