Rewiring & Renovation Electrical Work in Petaling Jaya

Common questions about rewiring & renovation electrical work

How much does rewiring a house cost in Petaling Jaya?

It depends heavily on house size and how much of the wiring needs replacing. A full rewire of a single-storey terrace house typically runs into several thousand ringgit once you include wiring, new consumer unit, wall chasing and patching, while a partial rewire (just the kitchen or one floor) costs less. Get itemized quotes from at least two electricians so you can compare wire gauge, breaker specs, and labor separately rather than one lump figure.

How often does a house need rewiring?

Most homes don't need a full rewire on a fixed schedule, but wiring older than 25-30 years, especially rubber or PVC-insulated cable from older builds, is worth having inspected before any major renovation. Signs it's overdue include frequently tripping breakers, warm switch plates, or an old ceramic fuse board instead of a modern consumer unit.

What should I expect during a rewiring or renovation electrical job?

Expect an initial site visit to assess the existing wiring and agree on the new layout, then a rough-in stage where cables and conduits go in before walls or ceilings are closed up, followed by fitting switches, sockets and the consumer board, and a final test. For a full house this can take anywhere from a few days to a couple of weeks depending on scope, and it usually needs to be coordinated with your contractor's timeline.

How can I judge the quality of an electrician's rewiring work?

Check that they use proper conduit and correctly rated cable rather than exposed wiring, that the consumer unit has clearly labeled circuits, and that they test and show you the results (like earth continuity and RCB trip tests) rather than just packing up when it looks done. A written scope and warranty on labor are good signs of a business that stands behind bigger jobs.
