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.
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.

Diagnosis and replacement of energisers that have stopped pulsing, dropped output voltage, or failed after a power surge or lightning strike.
Tracing and correcting poor or failed earth connections — the single most common cause of nuisance tripping and weak fence performance.
Replacing broken or sagging strands, correcting tension, and isolating individual zones so one fault doesn't take the whole system offline.
Complete new electric fence installations to current standards, on walls, free-standing posts, or a combination of both.
Wiring the fence energiser into an existing alarm panel or estate monitoring system so a trip triggers a proper notification.
Installations carried out to current electric fence standards, with correct warning signage and clearance heights.
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.
Electric fence call-outs are available across these estates and suburbs — select yours for local detail, or call directly.
