Why Cronulla Homes Often Need Rewiring
A significant portion of Cronulla's housing stock was built during the post-war period through to the 1970s, when rubber-sheathed and early PVC wiring was standard. Decades of exposure to the coastal environment — salt air, humidity, and temperature cycling — accelerates insulation breakdown on that era of cable in ways that rarely happen inland. If your switchboard still has ceramic fuses or early circuit breakers rather than modern RCDs, that's a reliable sign the wiring itself is the same age.
Beachside and canal-front homes along Gunnamatta Bay and Dolans Bay Road are particularly susceptible. Salt-laden air corrodes terminations inside outlets and light fittings, and older two-wire systems (active and neutral only, no earth) can't safely support today's appliance loads or meet current safety standards. DIY additions made over the decades — extra power points, granny flat circuits run off the main board — often compound the hazard.
A rewire isn't simply swapping cable. The process starts with a full inspection: every accessible circuit is tested with a multifunction tester to measure insulation resistance and continuity. That data drives the scope — some homes need a full rewire, others need targeted replacement of degraded circuits and a switchboard upgrade. Walls are accessed via existing outlets and ceiling roses wherever possible to reduce patching. Once cabling is complete, every circuit is individually tested before the board is energised, and a Certificate of Compliance is issued.

Step-by-Step: How a Cronulla Home Rewire Works
Every rewiring job follows the same disciplined sequence. There are no shortcuts — the sequence exists because each stage depends on the one before it being correct.
- Stage 1 — Inspection & testing: insulation resistance tests on every circuit identify which cables are degraded and whic
- Stage 2 — Scope agreement: a written quote details exactly which circuits are being replaced, the cable routes planned,
- Stage 3 — Isolation & make-safe: the property is safely de-energised; temporary supply arranged where required for owner
- Stage 4 — Cable installation: new TPS cable is drawn through ceiling spaces, wall cavities, and conduit runs to each out
- Stage 5 — Switchboard upgrade: old fuse wires and ceramic carriers are replaced with modern circuit breakers and dual RC
- Stage 6 — Testing & certification: every circuit undergoes polarity, earth continuity, and insulation resistance testing
