Electric fence repairs in Johannesburg South

Before you book, a quick look often tells you what kind of fault you have. Do all of it without touching the fence:

1. Read the keypad or energiser. Is it on, and what is it showing? An alarm on one zone points to that stretch of fence; every zone at once points to the energiser, its power or its battery.
2. Switch the fence off at the keypad before going near it.
3. Walk the boundary and look, from a safe distance: branches, creepers or grass touching the lines, a line that has snapped or sags, a cracked insulator, rubbish caught on the wires.
4. Check the gates. An open gate, or a gate contact that has come loose, keeps an alarm going.
5. Think about the battery. If the fence drops out in power cuts, the backup battery is likely worn; Nemtek suggests checking batteries twice a year.

If you find something you can clear safely with the fence off, such as a branch, do so and switch the fence back on. If not, book us. Never touch a line that may be live, and never open the energiser. The full set of checks is in the fault finder below.

• Broken and sagging lines, joined with proper fittings and re-tensioned.
• Failed insulators and brackets, replaced along the run.
• Earth faults, with spikes reset or replaced.
• Gate contacts and sirens that have stopped working, or never stop.
• Energisers and keypads that are dead, alarming without cause or damaged by a storm, repaired on the bench or replaced.
• Worn backup batteries.

One fault isn't a fault at all: a fence that suddenly reads weak may simply have been left on low power. Nemtek's Druid, for one, has a low-power mode for times when children are playing near the fence, and it's easy to forget to switch it back.

All our spare parts are genuine, and every repair carries our six-month guarantee on our repairs.

An older fence may be just a few lines on a wall with a single-zone energiser, while the needs of the house have moved on. Common upgrades:

• More lines, to make the fence taller and harder to get over.
• More zones, so an alarm tells you which side to check. Nemtek's Druid 25 and 28 are two-zone energisers, and two can be networked for four zones.
• A keypad inside the house, so the fence can be armed, disarmed and read without going outside.
• A siren and strobe where the neighbours, or an armed response company, will notice them.

A two-zone Nemtek Druid 28 LCD is typically about R5 190–R5 210 (Takealot, NeonSales) in shops, before fitting. We look at the fence before suggesting what's worth changing, and keep what's still sound.

If a property with an electric fence changes hands after 1 October 2012, an Electric Fence System Certificate is required, even if the fence is older than that. It has to come from a registered electric fence installer, and a fence that doesn't comply has to be repaired before it's issued. Ask your conveyancer early what they need, so the certificate is ready when they ask.

Certified electric fence installer. An inspection and certificate for a fence that already complies typically costs R850–R1 500 (Kandua, Completo) in the market (prices checked October 2026). More is on electric fence certificates.

On the job card, choose Johannesburg and put your southern suburb in the address. Tell us what the keypad shows and what your five-minute check found; a photo of the energiser helps. Same-day repairs are part of the week in the south when bookings allow, and the 24/7 emergency repairs across Gauteng cover a fence that won't stop alarming at night. No call-out fee when we do the work. If no work is done, a R650 call-out fee applies.
