Aluminum Wiring Replacement & Repair

Many buildings built in the 1960s and 1970s have aluminum wiring, which can deteriorate over time and create fire hazards. We offer thorough inspections, repairs, and replacement of aluminum wiring to meet current standards and make sure your place is properly covered by insurance. We can upgrade your wiring if you have:

  • Flickering lights
  • Overheated or damaged switch plates
  • Blown fuses
  • Burning smell near switches
  • Smoking or sparking outlets

Key issues:

  • Limited Power: Only 15 amps, which can cause overloads
  • Deteriorated Insulation: Increases fire risk
  • No Grounding: Creates serious hazards
  • Insurance Issues: Many insurers won’t cover it or charge higher premiums

Electrical Rewiring FAQs

How do I know if my home needs electrical rewiring?

Signs like flickering lights, frequent breaker trips, blown fuses, discolored outlets, or old aluminum/knob-and-tube wiring may indicate the need for rewiring. Our licensed Toronto electricians conduct inspections and upgrades for efficiency.

How much does home rewiring cost?

Rewiring costs depend on property size, wiring type, accessibility, and project complexity. We provide customized quotes after assessment.

How long does it take to rewire a house in Toronto?

The timeline depends on the size and complexity of the project. After assessment, we provide a clear timeline and minimize disruption.

Is it safe to live in a home with old wiring?

Older electrical systems may present shock and fire risks. Aluminum and knob-and-tube wiring often require professional evaluation.

What does a rewiring project involve?

Rewiring involves replacing outdated wiring, upgrading to current standards, and routing new cables.

Do I need to leave my house while it’s being rewired?

You typically don’t need to leave, though there may be brief disruptions. Temporary vacating may be required in specific areas.
