From upgrades and repairs to complete home rewiring, our licensed electricians complete every project on time, within budget, and to current safety standards.
Aging electrical infrastructure often requires specialized assessments, as outdated wiring can affect both safety and performance. Every home is wired differently, which is why we evaluate each electrical system individually and recommend the most appropriate rewiring solution. As an ESA-authorized electrical contractor, we perform electrical inspections, repairs, and rewiring services in accordance with Ontario Electrical Safety Code requirements. We also provide electrical wiring services for residential and commercial properties.
Aluminum Wiring Replacement & Repair
Many homes built in the 1960s and 1970s were wired with aluminum wiring as a lower-cost alternative to copper wiring. While functional, aluminum wiring can deteriorate over time, leading to loose connections, overheating, and potential fire hazards. We provide thorough electrical system inspections, repairs, and aluminum wiring replacement services to help meet current safety standards and address insurance coverage requirements. You may require an inspection, repair, or wiring upgrade if you notice:
Knob and Tube Rewiring Toronto
A knob-and-tube electrical system uses porcelain knobs and tubes to support and isolate electrical wiring. While knob-and-tube wiring is not inherently dangerous, regular inspections, maintenance, and repairs are important to help minimize electrical hazards and ensure safe operation. Our licensed electricians can inspect, repair, or replace existing knob-and-tube wiring and recommend the most appropriate solution based on your home’s electrical system and current power requirements.

Electrical Rewiring Services FAQs
Common signs that a home may need electrical rewiring include flickering or dimming lights, frequently tripping circuit breakers, regularly blown fuses, sparking outlets, discolored outlets or switches, burning smells, power fluctuations, electrical shocks, and an increasing reliance on extension cords. Older homes with outdated wiring, aluminum wiring, knob-and-tube wiring, or porcelain fuses should also be evaluated by a licensed electrician.
The cost of electrical rewiring depends on the size of the property, accessibility of existing wiring, project complexity, and the extent of upgrades required. We provide customized quotes following an assessment of your home’s electrical system and rewiring needs.
The time required to rewire a house depends on the size, age, layout, and complexity of the electrical system. Most rewiring projects take several days to complete. After assessing the property, we provide a clear project timeline and work to minimize disruption whenever possible.
Older electrical systems may present shock and fire risks, especially if they contain aluminum wiring, knob-and-tube wiring, deteriorated insulation, or loose electrical connections. A licensed electrician can inspect the system and determine whether repairs, upgrades, or complete electrical rewiring are necessary.
Electrical rewiring involves inspecting the existing electrical system, removing or bypassing outdated wiring, installing new electrical wiring and cables, upgrading outlets, switches, and electrical devices, and testing the system to ensure compliance with current Ontario Electrical Safety Code requirements. The exact process depends on the property’s size, age, and wiring condition. Learn more about whole home rewiring.

Depending on the scope of the project, temporary relocation from specific areas of the home may occasionally be necessary.
