  3. Buying an Older Home in the GTA? What an Electrical Inspection Finds
Guide · Updated October 2026

Buying an older home: the electrical

A general home inspection flags electrical concerns. An electrician's inspection tells you what they are, how urgent they are and roughly what they'll cost to fix.

What we look at

  • Service size, meter base and main panel condition
  • Breaker sizes against wire gauges
  • Knob and tube or aluminum branch wiring
  • Grounding and bonding
  • GFCI/AFCI protection
  • Signs of DIY or unpermitted work
  • Thermal scan of the panel under load

Common findings in older GTA homes

Undersized services, overcrowded panels, double-tapped breakers, ungrounded receptacles, remaining knob and tube in attics or walls, and basement wiring added without a permit.

Using the report

A prioritized list with ballpark costs helps you negotiate, plan renovations and talk to your insurer before closing. Book the inspection during your conditional period.

See electrical safety inspections.

Quick questions

How long does an inspection take?

Usually 1.5 to 3 hours for a typical house, plus the written report.

Can the seller's inspection replace mine?

It can help, but an independent inspection for you as the buyer is worth having.

Will you quote the repairs?

Yes — the report includes ballpark costs, and we can quote the work separately.
