Garden Lighting Gone Dark? We'll Light Your Evening Again

A garden lighting system that's worked for years and then half-dies one evening is following a well-worn script. Everything outdoors — buried cable, weather-exposed fittings, connectors in damp soil — ages faster than anything in the house, and the failure patterns are specific to that environment. Here's what typically goes wrong, how we find it, and how we fix it so it stays fixed.

How Garden Lighting Systems Work — and Why They Fail

Most garden lighting runs one of two ways. Low-voltage systems use a transformer (usually indoors or in a weatherproof box) stepping the supply down to 12V, with a cable loop feeding each fitting. Mains-voltage systems run armoured cable or conduit-protected wiring to each light. Both fail at their weakest points, and outdoors the weak points are everywhere the system meets the weather.

Water is the enemy number one. Connectors that weren't rated for burial sit in damp soil and corrode. Fittings whose gaskets have perished let rain into the terminals. Underground junction boxes that were never properly sealed fill with groundwater each wet season. Then there's the mechanical world: a spade through a cable while planting, a lawn edger nicking a buried run, roots slowly crushing a conduit. And transformers fail with age, sometimes partially — some fittings work, others don't, with no obvious pattern.

Telling the Fault's Shape Before We Start

The pattern of the failure is the best clue you can give us. Everything out at once points to the transformer, the supply to it, or its indoor switch or breaker. Half the system out — say, everything past the pond — points to a break or corroded joint in the cable run at that point. One fitting dead while its neighbours shine is usually that fitting: a lamp, a waterlogged housing, a corroded terminal. Fittings that flicker or dim when it rains are telling you outright that water is getting into a connection.

If any digging, planting or landscaping happened recently, tell us — a nicked cable is an entirely different search from a corroded connector.

How We Trace It

Garden fault-finding is methodical outdoors work. The engineer isolates the system, then tests from the supply inward: transformer output, cable continuity run by run, voltage at each fitting in sequence. Low-voltage systems give a clean signal here — voltage decays or vanishes past the fault, and the measurement walks us straight to the break. Where cable runs are buried and unmarked, we can locate a break with proper test equipment rather than digging up the whole border on speculation, which keeps your planting where you put it.

Every opened connection gets examined for water and corrosion, because fixing a break while leaving the damp joint that caused it just schedules the next failure.

The Repair — Built for Outside

Repairs outdoors have one rule above all: whatever we remake must be sealed for permanent burial or permanent weather. Corroded connectors are replaced with proper IP-rated underground jointing, not tape and hope. Waterlogged fittings are dried, re-gasketed or replaced with units correctly rated for their exposure. Damaged cable runs are repaired with armoured or appropriately protected cable, routed and marked so next year's planting doesn't find them the hard way. A failed transformer is replaced with one correctly rated for the load it feeds — undersized transformers run hot and die young.

Where the system has grown by accretion over the years — fittings added piecemeal, joints accumulating — we'll point that out and can tidy the wiring into a sane, maintainable layout if you want it.

Aftercare That Actually Helps

A garden system asks for occasional attention: lens gaskets age, connectors in wet corners deserve a look after a few winters. We'll leave you with a straightforward note of what was fixed, where the joints now sit, and what to watch for. And if you're planning more garden lighting later, tell us — designing the runs properly from the start beats bolting fittings onto a system that was never planned.

When to Call Us

Book when fittings die, flicker or dim — especially after rain; when a transformer hums loudly or smells warm; when a breaker feeding the garden lighting trips repeatedly; or whenever digging has been done near the lighting runs. A repeatedly tripping garden circuit is a prompt call, because damp in buried joints only ever worsens.
