Knob-and-tube & aluminum wiring in older Ottawa homes

Why older Ottawa wiring gets flagged by insurers, and how an ESA-permitted rewire during a renovation fixes it for good.

If your Ottawa home was built before 1950 — think Centretown, the Glebe, Old Ottawa South, Sandy Hill — it may still hide knob-and-tube circuits. Homes built between roughly 1965 and 1976 sometimes have aluminum branch wiring. Both can be flagged on home-insurance renewals.

Why it matters

Older wiring was not designed for modern electrical loads, and insurers increasingly ask about it — sometimes declining coverage or requiring remediation. Beyond insurance, it is a safety consideration worth addressing.

The renovation advantage

The best time to rewire is during a renovation, when walls are already open. Coordinating a full or partial rewire with your project avoids paying twice for drywall and finishing. Our electrical work is performed and certified to ESA (Electrical Safety Authority) standards.

What we do

We assess the existing wiring at quote time, coordinate an ESA-permitted rewire where needed, and schedule the required inspections — so the finished space is safe, compliant, and insurer-friendly.
