Why Choose Our Rewiring Service

Signs Your Home Needs Rewiring

Age of Wiring

Electrical wiring has limited lifespan. Homes built before 1970 likely have outdated wiring systems requiring replacement. Pre-1950 homes often have dangerous cloth or rubber-insulated wiring that deteriorates causing fire hazards. Wiring from 1970-1990 may lack adequate circuits and safety features. We inspect older homes and identify electrical systems needing replacement or upgrades. Modern rewiring improves safety and increases electrical capacity. For comprehensive electrical system evaluation, see our electrical safety inspection services.

Visible Warning Signs

Your home may show signs indicating dangerous wiring including circuit breakers tripping frequently, flickering or dimming lights throughout home, discoloured or warm power points and switches, burning smell from electrical outlets, old fuse boxes instead of circuit breakers, visible fabric or rubber-insulated cables, and insufficient power points requiring power boards. These symptoms indicate wiring problems requiring professional attention. Never ignore electrical warning signs - they indicate potential fire hazards. For urgent electrical issues, contact our emergency electrician.

Renovation Opportunities

Renovations provide ideal opportunities for rewiring. When walls are opened for structural work, electrical rewiring becomes more accessible and cost-effective. We coordinate rewiring with renovation schedules, running new cables while walls are accessible, installing updated power point and lighting layouts, and upgrading to modern electrical systems. Combining rewiring with renovations minimises additional disruption and reduces overall project costs. For renovation electrical work, see our complete electrical installation services.

House Rewiring Process

1. Initial Assessment and Quote

We begin rewiring projects with comprehensive electrical assessment including inspection of existing wiring condition, evaluation of switchboard and circuits, identification of safety hazards and code violations, measurement of electrical loads and requirements, and preparation of detailed rewiring plan and quote. This assessment identifies work scope ensuring accurate pricing and proper planning. We explain required work and coordinate timing minimising disruption.

2. Planning and Preparation

Before starting rewiring, we plan the new electrical system including designing circuit distribution, planning power point and lighting layouts, sizing switchboard and protection devices, coordinating with renovation work if applicable, and obtaining necessary electrical approvals. Proper planning ensures efficient installation and optimal electrical system design. We provide electrical plans showing circuit distribution and fixture locations.

3. Rewiring Installation

Our electricians complete rewiring systematically by isolating and removing old wiring safely, running new cables through walls and roof cavities, installing new switchboard with modern protection, wiring all circuits with appropriate cable sizing, installing power points and switches throughout, connecting lighting circuits and fixtures, and installing RCD safety switches protecting all circuits. We use quality materials and workmanship ensuring long system life. For ceiling electrical work including downlights, we provide integrated installation.

4. Testing and Certification

Before energising rewired systems, we conduct comprehensive testing including insulation resistance testing of all circuits, earth continuity verification, polarity testing of all outlets, RCD trip time testing, and circuit load testing. We provide electrical safety certificates and compliance documentation required for insurance and property transactions. All rewiring meets Australian Standards AS/NZS 3000 requirements.

Types of House Rewiring

Specific Rewiring Scenarios

Aluminium Wiring Replacement

Some 1970s homes have aluminium wiring that poses fire risks at connection points. Aluminium expands and contracts more than copper causing loose connections that overheat. We replace dangerous aluminium wiring with modern copper cables, install appropriate connection devices if partial replacement, and ensure safe electrical system operation. Aluminium wiring requires immediate attention - it creates significant fire hazards especially at power points and light switches.

Knob and Tube Wiring

Very old homes may have knob and tube wiring from early 1900s. This antique wiring system has no earth wire, uses deteriorated insulation, cannot safely power modern loads, and is extremely dangerous. Complete removal and replacement is essential. We carefully remove knob and tube wiring and install complete modern electrical systems. Never attempt to extend or modify knob and tube wiring - it must be completely replaced.

Two-Wire Systems Without Earth

Older homes often lack earthing systems creating shock and fire hazards. Modern electrical systems require proper earthing for safety and RCD operation. We install earthing systems throughout rewired homes including earth electrodes meeting resistance requirements, earth bonding of water and gas services, earth connections to all power points and fixtures, and verification of earthing system integrity. Proper earthing is essential for electrical safety and RCD protection to function correctly.

Modern Electrical System Features

Adequate Circuits

Modern homes need multiple dedicated circuits. We install separate circuits for kitchen appliances, laundry appliances, air conditioning systems, lighting throughout home, power points in each area, and special equipment or workshops. Adequate circuits prevent overloading and circuit breaker trips. We calculate electrical loads and install appropriate numbers of circuits sized correctly for connected loads. For ceiling fans and major appliances, dedicated circuits ensure reliable operation.

RCD Safety Switches

Modern rewiring includes RCD safety switches protecting against electric shock. RCDs detect current leakage indicating faulty appliances or wiring faults, disconnect power within milliseconds preventing electrocution, and protect all circuits including lighting and power points. We install RCD protection throughout rewired homes meeting current safety requirements. RCD protection is mandatory for new electrical work and strongly recommended for all homes.

Surge Protection

Electrical surge protection safeguards sensitive equipment from voltage spikes. We install whole-house surge protection devices in modern switchboards protecting computers, entertainment systems, appliances, and electronics from lightning strikes, power surges, and electrical faults. Surge protection prevents expensive equipment damage and extends appliance life. Modern homes benefit from integrated surge protection during rewiring projects.

Rewiring and Property Value

Professional rewiring adds value to older homes by eliminating safety hazards, modernising electrical capacity, meeting building code requirements, and improving insurance eligibility. Rewiring documentation provides evidence of electrical system quality for property sales. Many buyers require electrical safety certificates before purchase - compliant rewiring facilitates smooth property transactions. For complete property electrical compliance, combine rewiring with smoke alarm installation and safety inspections.

House Rewiring Costs

Rewiring costs vary based on house size and number of rooms, extent of rewiring required, accessibility of ceiling and wall cavities, switchboard replacement requirements, additional features like extra circuits or automation, and whether combined with renovation work. We provide detailed quotes specifying all work included.
