The voltage surge when the power comes back after load shedding burns out the energiser's internal circuit board — the single most common electric fence fault we see across Rosebank. If the indicator light is red or off after the power returned, it is almost certainly a surge-damaged board. We carry Nemtek, Stafix and JVA stock for same-day energiser (energizer) replacement. Call 061 402 6299 and we will confirm it over the phone.

SANS 10222-3 specifies a minimum of 5 live strands for a compliant installation. Most Johannesburg residential installations use 6–8 strands for better coverage. The strands must be properly spaced, tensioned and earthed, and warning signs must be displayed at regular intervals. All our installations comply with SANS 10222-3 and include a COC certificate.call 061 402 6299 for emergency repair.

Constant alarming almost always means a wire is shorting to earth — vegetation touching the line, a sagging strand, a fallen bracket or a cracked insulator. We fault-find the affected zone and clear or repair it, usually R650–R1,400. It's rarely the energiser itself when the symptom is over-alarming rather than no power.

No. Electric fence installation in South Africa must be carried out by a registered installer under the OHS Act Electrical Machinery Regulations. DIY installation is illegal and will result in an invalid COC — which is required by law and for insurance purposes. If someone is injured by an illegally installed fence, the property owner faces criminal liability.

A standard residential electric fence installation in Johannesburg takes 1–3 days depending on perimeter length and complexity. We usually start within 48–72 hours of the free site assessment. The COC certificate is issued on the day of completion.

A fence that reads voltage but doesn't deliver a proper shock is nearly always an earthing problem — the most common cause of weak output. A good earth needs at least three galvanised stakes driven into moist ground. We test earth resistance and correct it; sometimes the energiser is also undersized for the line length and needs upsizing.

Yes. All parts and workmanship carry a 6-month guarantee. New installations also carry the COC certificate which confirms compliance with SANS 10222-3 on the day of completion. If any fault develops within 6 months of our work, we return and fix it at no charge

Yes — we work on Nemtek (Wizord, Merlin, Stealth, Druid, Agri), Stafix, JVA, Gallagher and others, plus solar energisers and DSC/Risco fence-alarm integration. Where a board is beyond economical repair, we replace it with a like-for-like unit so your existing brackets, wire and keypad stay in place.

Most "dead" fences need a single part — an energiser, a battery, a wire or an earth fix — not a new installation. We test first and quote you on the actual fault. If a full re-string or new energiser genuinely is the right call, we show you why on the tester. We don't upsell a R25,000 installation to fix a R900 fault.

It depends on the fault. A battery replacement is typically R650–R1,200, an energiser board repair R600–R1,500, and a full energiser replacement R1,800–R6,500 depending on the model. Call-out and diagnosis is from R450 and is waived when you proceed with the repair. We give you an honest price range over the phone before driving out.

You need an Electric Fence System Certificate of Compliance for any new installation, and whenever a property with an electric fence is sold (for systems installed or transferred after 1 October 2012). It is separate from the normal electrical COC. Minor repairs do not need a new one, but replacing the energiser does. We arrange certification through a registered installer.

Quarterly is ideal given the Highveld's seasonal swings — surge and vegetation pressure in summer, dry-earth and battery stress in winter. At minimum, an annual service keeps voltage, earthing and the alarm output in check and keeps your COC position clean. Our maintenance contract from R2,400 a year covers four visits and a written report.

A beeping energiser has latched a fault — usually a wire shorting to earth, a low backup battery, or a tamper/cut detection. On keypad units you silence it by entering your PIN, but that only mutes the symptom; the fault stays until it's fixed. We read the fault on the LCD where fitted, isolate the zone that's dragging the voltage down, and clear the actual cause so it stops for good rather than beeping again the next night.

Yes — we service the gated clusters and apartment complexes around the Rosebank node, including multi-zone JVA and Nemtek systems, and coordinate with the managing agent or building management. For common-property fencing the COC is usually the body corporate's responsibility, and we confirm where it sits before any work.

Yes. A solar energiser runs off its own panel and battery and never sees the mains spike that destroys grid-powered units when the power returns — so if you've lost two or three energisers to surges, converting to solar is the permanent fix. We supply and install solar systems and can fit a surge protector as a lower-cost interim step. We'll quote both options on a free assessment so you can weigh the once-off cost against repeat repairs.

The circuit completes through the ground, so a fence can read kilovolts and still give no real shock if the earth system is weak. Rosebank's dry winter soil makes this worse. We measure earth-return voltage and add or re-drive earth stakes into moist ground to restore the bite.

Yes. We repair and replace all the major brands — Nemtek (Wizord, Merlin, Stealth, Druid), JVA (Z-series), Stafix, Gallagher and others — and integrate with DSC and Risco alarm panels. We carry the common Nemtek, Stafix and JVA units for same-day Rosebank replacement.

Green means normal and red or no light means a fault. After a power cut, a red light almost always points to a surge-damaged board — the most common reason for electric fence repairs Rosebank homeowners call us. We test open-circuit output to confirm: a healthy unit pulses around 7–9 kV.

Yes. We are based in Broadacres and run a 24/7 emergency line, so for electric fence repairs Rosebank we reach most suburbs quickly and carry common energisers and spares on the vehicle. If your fence is down after a break-in attempt, call 061 402 6299 straight away.

Fault finding is the core of what we do. Many Rosebank call-outs are simply locating a short, a break or an earth fault on an otherwise healthy fence. We trace it with a directional fault-finder, show you the exact point of failure, and repair only what is broken — no unnecessary parts.
