Owners of large Karen properties know the frustration: the energiser shows a fault every morning, the guards say monkeys or branches tripped it, and over time everyone stops paying attention to the alarm. A fence that is ignored is barely a fence at all.

Electric fence installation in Karen needs to account for long boundaries, heavy vegetation and wildlife. Nerpax walks the full perimeter, notes overhanging trees and hedges, and designs a fence with the right height, spacing and clearances. On long boundaries, we split the fence into zones so a fault can be found quickly instead of searched for along hundreds of metres.

We install with good earthing, which matters in dry ground, and connect an energiser sized for the length. Alarms can sound at the house and send alerts to your phone. Existing fences can be tested, repaired and zoned.

Serving Karen

Karen is known for large leafy plots, long driveways and spacious homes, with Karen Road, Langata Road and Ngong Road framing the area. Big compounds mean long boundaries, so electric fencing, perimeter CCTV and intruder alarms with outdoor sensors are common needs. Many homes have boreholes, staff quarters and outbuildings, which makes solar pumping, solar power systems and a reliable generator changeover practical. Automated gates save trips down the driveway in the rain. Nerpax Systems serves Karen homes, schools and businesses with supply, installation and delivery.

Electric Fence Installation in Karen: FAQs

Why does our Karen electric fence keep giving false alarms?

The usual causes are vegetation touching the wires, poor earthing in dry soil, broken insulators, or animals touching the fence. We test each section, fix contact points and earthing, and can divide the fence into zones so you can see exactly where a problem is.

How tall should an electric fence be on a Karen boundary?

It depends on whether it sits on a wall or stands alone, and on the surrounding vegetation and terrain. Freestanding fences are usually taller than wall-top ones. We recommend a height and wire spacing for each section of your boundary after the site survey.
