FAQs
Why might a home in Cowan need a full electrical rewire?
Many houses in Cowan were built before current safety codes existed or before today’s high-demand appliances were common. Aging wiring, cloth-insulated cables, porcelain fuses, or an undersized switchboard can create fire and shock hazards. A whole-home rewire replaces outdated circuits with modern, correctly-sized copper cabling, RCD/RCBO protection, and a new switchboard that comply with AS/NZS 3000 (the Australian Wiring Rules). This ensures your property is safe, energy-efficient, and able to support new technology such as EV chargers, solar inverters, and smart-home systems.
What is involved in a whole-home rewire and how long will it take?
Our team begins with a thorough inspection and creates a circuit map of your existing installation. We disconnect the old wiring in stages, run new TPS cabling through wall cavities or roof spaces, install new sockets, switches, and light points, and fit a modern switchboard with safety switches. A typical three-bedroom Cowan home takes 4–7 working days, depending on size, access, and whether walls/ceilings are single-storey or double-storey. We coordinate with you to minimise power disruptions, often supplying temporary power so essential appliances keep running.
Will a rewire damage my walls or require extensive patching?
We use non-destructive cable routing wherever possible, fishing cables through roof voids, under floors, and within existing chases. Inevitably, some small holes (usually behind new outlets or in cornices) are required to pull cables. Our electricians patch these openings neatly, and we can arrange professional plastering and painting if you prefer a seamless finish. For homes undergoing other renovations, we schedule the rewire to coincide with open-wall stages to keep remedial work to a minimum.
How much does a whole-home rewire in Cowan cost?
Costs vary with property size, accessibility, number of circuits, and any upgrades (data, security, EV chargers). As a guide, a two-bedroom unit may start around $6,500–$8,000, while a larger four-bedroom house with three-phase supply could range from $12,000–$18,000. We provide a fixed-price, itemised quote after an on-site assessment, so there are no surprise extras. Our pricing includes materials, labour, safety switchboard, testing, NSW Fair Trading inspection fees, and a certificate of compliance (CCEW).
Do I need permits or inspections for a rewire?
Yes. NSW legislation requires licensed electricians to lodge a Notification of Electrical Work (NOW) and issue a Certificate of Compliance for Electrical Work (CCEW) upon completion. An independent Level 2 service provider or NSW Fair Trading inspector may audit the job. We handle all documentation and schedule inspections on your behalf, ensuring your installation is fully compliant and ready for connection by your energy retailer.
Can I stay in my home during the rewire, and how do you ensure safety?
Most residents remain in place during a rewire. We plan the project in stages, so only sections of the house are without power at any one time. Temporary lighting and power boards keep essential areas running. Live circuits are clearly labelled and isolated behind locked panels when not in use. Daily site clean-ups remove debris and exposed conductors. At the end of each day we restore power to kitchens, bathrooms, and any medical equipment. Your safety and comfort are our top priorities throughout the process.
