Worth knowing

Old wiring doesn't announce itself.

Many of the Lower North Shore's loveliest homes are older than their switchboards. The warning signs are quiet — until they aren't.

Three quiet warnings

each worth a phone call
Flickering lights
Often a tired connection — small to fix now, costly to ignore.
Warm switches or sockets
Heat where it shouldn't be is never a feature.
No safety switch
Older boards often lack one — a modest upgrade that protects everything behind it.

Not sure what's behind your switchboard? One call settles it.

Our story

65 years wiring the Lower North Shore.

Our vans have been a familiar sight around these streets for over 60 years — delivering quality electrical services wherever and whenever they're needed. From our retail and service centre on Cabramatta Road we handle everything from a flickering light to a full rewire.

And we still do things the old-fashioned way: bring in your table lamps and small appliances, and we'll re-wire and repair them on the bench.
