Electric Fence Installation & Repairs

Electric Fence Installation & Repairs in Johannesburg North

Energiser faults, earth faults, nuisance tripping, strand repair and full perimeter installations — same-day fault-finding across Sandton, Fourways, Waterfall, Kyalami and Johannesburg's established northern suburbs.

A Fence That Keeps Tripping Is Worse Than No Fence

Because most systems automatically isolate a faulty zone rather than leaving it live, a persistent fault often means a section of your perimeter is quietly unprotected while you assume the fence is doing its job. We trace faults systematically — earth connections, strand tension, energiser output, and physical contact points — rather than guessing and replacing parts one at a time.

We install and repair fences on top of existing boundary walls, on free-standing posts, and around irregular property lines including golf-course and open-land boundaries. On estates, we also work with body corporate and estate security specifications where the fence needs to integrate with a shared monitoring or alarm system.

What's Included

Electric Fence Services We Provide

Energiser

Energiser Fault-Finding & Replacement

Diagnosis and replacement of energisers that have stopped pulsing, dropped output voltage, or failed after a power surge or lightning strike.

Earthing

Earth Fault Diagnosis

Tracing and correcting poor or failed earth connections — the single most common cause of nuisance tripping and weak fence performance.

Strands

Strand Repair, Re-Tensioning & Zone Isolation

Replacing broken or sagging strands, correcting tension, and isolating individual zones so one fault doesn't take the whole system offline.

New Installs

Full Perimeter Installation

Complete new electric fence installations to current standards, on walls, free-standing posts, or a combination of both.

Integration

Alarm & Monitoring Integration

Wiring the fence energiser into an existing alarm panel or estate monitoring system so a trip triggers a proper notification.

Compliance

Standards-Compliant Installation

Installations carried out to current electric fence standards, with correct warning signage and clearance heights.

Common Problems We Fix

Electric Fence Symptoms We See Most Often

  • Energiser keeps tripping — usually an earth fault, moisture ingress, or strand contact with foliage or a wall.
  • Fence has no pulse at all — often a failed energiser, blown fuse, or a complete break in the circuit.
  • Weak or inconsistent pulse — commonly a poor earth connection or a partial short somewhere along the strand run.
  • One zone always shows a fault — usually isolated damage to that specific section, not the whole system.
  • Fence tripped after a storm — lightning and power surges are a common cause of sudden energiser failure.
  • Sagging or loose strands — tension loss over time from weather and thermal expansion; needs periodic re-tensioning.
Frequently Asked Questions

Electric Fence Questions

Frequent tripping is most often an earth fault, moisture inside the energiser or a connector box, or a strand touching foliage, a wall, or another conductive surface. Most systems automatically disable the affected zone rather than leaving it live, so a persistent trip can leave part of your perimeter effectively unprotected until the fault is cleared.

Treat it as urgent rather than a minor annoyance. A zone that keeps disabling itself is a zone that isn't doing its job, and the cause — often an earth fault — can also affect the reliability of the rest of the system over time.

Yes, this is one of our most common installations — brackets mounted along the top of an existing boundary wall, wired to a new or existing energiser. We assess wall height and condition first, since the wall needs to be structurally sound enough to carry the bracket load.

Not necessarily, but it can be. Many estate and suburban homes wire their electric fence energiser into the existing alarm panel so a fence trip also triggers a notification, rather than running as a fully separate system. We can set this up or work with what's already installed.
