Why Sutherland Shire Homes Often Need Rewiring
Sutherland Shire has a large stock of brick-veneer and fibro homes built between the 1950s and 1980s. Many of these still carry the original rubber-sheathed or early PVC wiring, which degrades and becomes brittle over time — a particular problem in the warmer, humid conditions near the coast in Woolooware and Cronulla. When insulation cracks, conductors can arc against framing timber and start fires inside wall cavities where they go undetected for minutes.
Double-brick construction common in Caringbah and Gymea creates its own challenges: running new cable through solid masonry requires careful planning with concealed conduit or surface containment, rather than the open-wall access you get during a renovation. Getting it right the first time avoids revisiting finished walls.
The other common trigger in this area is a switchboard upgrade that reveals how much the downstream wiring has deteriorated. A new switchboard with RCD protection is only as safe as the circuits it feeds. If the cable feeding a circuit is undersized or degraded, the protective device cannot do its job correctly. PTY Unlimited assesses the full picture — switchboard and wiring together — rather than treating them in isolation.
Full rewires also future-proof a home for modern electrical loads. Homes built before 1990 were designed around far fewer circuits. Adding air conditioning, EV charging or a home office to an already-stretched system without upgrading the wiring creates persistent nuisance tripping and, at worst, sustained overload on conductors never rated for continuous high current.
How a Full Home Rewire Actually Works
A rewire is not a single-day job and the process matters as much as the outcome. PTY Unlimited follows a structured sequence that keeps disruption predictable and ensures every new circuit is tested before walls are closed up.
- Pre-work audit: every circuit traced, load measured, and degraded sections identified before a cable is pulled
- New cable is twin-and-earth 2.5mm² for power circuits and 1.5mm² for lighting, both to current AS/NZS 3000 requirements
- Where walls remain intact, cable is fished through ceiling spaces and down internal wall cavities using flexible rods —
- All new circuits are terminated at a new or upgraded switchboard with dedicated RCD protection per circuit group
- Each circuit is load-tested and polarity-checked before reconnection
- A Certificate of Compliance for Electrical Work (CCEW) is issued on completion — required for insurance and future sale
