Many homes have an electric fence on the wall that nobody has tested in years, so electric fence installation in Nairobi is only worth paying for if the fence stays live along its full length. The energiser light may still blink, but sections can be dead from vegetation, broken insulators or poor earthing, and intruders look for exactly that.

Nerpax Systems installs and repairs electric fences across Nairobi County, from wall-top fences on homes in Lavington, Langata and South B to free-standing perimeter fences around larger plots in Karen and Runda, schools, warehouses and estates. We survey the boundary, then supply and install a suitably rated energiser, high-tensile wire, insulators, brackets or posts, a proper earth system and warning signs.

Long perimeters are split into monitored zones, and fences can be linked to an alarm, siren or guard house so tampering is noticed immediately. Battery backup keeps the fence live through power cuts. We test voltage section by section before handover. We are based in Kiambu; nearby pages cover Kikuyu and Ruiru. In Nairobi, book a site visit.

Serving Nairobi

Nairobi packs almost every kind of property into one county: office towers in the CBD and Upper Hill, apartment blocks in Kilimani and along Thika Road, leafy compounds in Karen and Runda, and busy industrial yards off Mombasa Road and in Industrial Area. Each brings its own worries. Landlords need intercoms, access control and CCTV covering shared entrances, businesses want cameras they can check from a phone, and homeowners want gates, fences and alarms that work when the area loses power. Frequent KPLC interruptions also make UPS units, inverters and generator changeovers a common request. Nerpax Systems serves the whole county with supply, installation and delivery.

Electric Fence Installation in Nairobi: FAQs

Can you repair an old electric fence on my Nairobi home?

Yes. We test the energiser, earthing and each section of wire to find where voltage is lost, then replace broken insulators, tighten or replace wire and improve the earth system. If the energiser is faulty or too weak for the fence length, we recommend a suitable replacement.

Can an electric fence be linked to my alarm system?

Yes. Most modern energisers have an alarm output that triggers when the fence is cut, shorted or switched off. This can sound a siren, alert your alarm panel or notify the guard house, so a problem with the fence is never silent.

Is a wall-top or free-standing fence better for my Nairobi property?

Wall-top fences suit properties with solid boundary walls and are neat and compact. Free-standing fences suit open boundaries, larger plots and properties without walls. We assess your boundary during the survey and recommend the type that gives reliable coverage.
