Electrician Kommetjie

Thermo Group — Trusted Electricians in Kommetjie

Kommetjie is one of the Southern Peninsula’s most exposed coastal villages, and its electrical installations take a harder beating than most. Thermo Group provides qualified, insured electricians for Kommetjie homes, holiday cottages and small businesses – from fault-finding and DB board upgrades to rewiring and Certificates of Compliance.

Between the salt in the air, the south-easter in summer and the north-westers in winter, wiring, isolators and outdoor fittings here age faster than they do inland, and we plan our work around that.

What We Watch For In Kommetjie

🌊
Salt Air & Corrosion
Constant sea air eats into DB board contacts, outdoor sockets, pool and garden lighting circuits, and we check for corrosion and moisture ingress on every Kommetjie callout.
💨
Wind & Weather Damage
Strong south-easters loosen overhead feeds and outdoor fittings, and driving winter rain finds its way into poorly sealed junction boxes, isolators and external lights.
🏖️
Holiday Homes & Rentals
Many properties here are lived in only part of the year, so faults can sit unnoticed for weeks. We inspect, test and certify before tenants and guests move in.
🏡
Older Cottages
Original wiring in older cottages was never designed for modern geysers, underfloor heating or inverters, and we upgrade circuits and DB boards to cope safely.

Why Kommetjie Wiring Ages Faster

Kommetjie sits on the Atlantic side of the peninsula with very little between the houses and the open ocean. Salt-laden air settles on everything, and over a few years it corrodes the copper terminations inside distribution boards, the screws in outdoor sockets and the metal casings of isolators. Corrosion raises resistance, and resistance creates heat, which is one of the quieter causes of electrical faults in coastal homes. When we inspect a Kommetjie installation we look closely at outdoor and semi-exposed points first, because that is where problems usually start.

Moisture is the other half of the story. Wind-driven rain can push water past seals that would hold perfectly well further inland, and a damp junction box or a weeping garage socket will trip an earth leakage unit long before it becomes dangerous. If your earth leakage keeps tripping in wet weather, it is often telling you exactly that, and we trace the circuit instead of simply resetting it.

Holiday Homes, Long-Term Rentals and Owner-Occupied Houses

Kommetjie has a high share of holiday homes and let properties alongside permanent residents. Landlords and agents need a valid Electrical Certificate of Compliance before a sale or a new tenancy, and holiday-home owners want to know the installation is safe to leave switched on for weeks at a time. We carry out full inspections, repair what fails and issue the certificate in one visit wherever possible, so there is no second round of callouts.

For permanent residents, the most common requests are DB board upgrades with proper earth leakage and surge protection, additional circuits for kitchens and home offices, and getting the house ready for a solar or battery backup installation. Because we also install and maintain solar systems, we can size the DB board and wiring correctly for an inverter from the start rather than leaving that for someone else to find later.

Lighting, Security and Outdoor Circuits

Gardens, braai areas, garages and perimeter security are a big part of life in Kommetjie, and all of them depend on outdoor electrical points that deal with weather. We install and repair outdoor lighting, gate motor and electric fence supplies, pool pump circuits and garden sockets using weather-rated components and correct earthing. Where a circuit has to run through a damp area, we choose the cable and enclosure to match instead of reusing indoor fittings.

Beyond Installation — We Maintain What We Wire

Our relationship with Kommetjie clients does not end at sign-off. We follow up on DB boards, backup power and outdoor circuits after a few months of coastal weather, so corrosion and moisture problems are caught before they become emergencies.

Certificate of Compliance You Can Rely On

Electrical work is only complete once it’s properly certified. Our electricians issue a valid Electrical Certificate of Compliance (COC) after rewiring, DB upgrades or fault repairs — essential for insurance, sale of property, or municipal sign-off. See our Residential Electrical Services page for our full range of home electrical work.
