The Annex · Knob & Tube Rewiring

Knob & Tube Rewiring The Annex.

The Annex contains some of Toronto's most significant Victorian and Edwardian architecture — and some of its most complex rewiring challenges. Original plaster ceilings, decorative moldings, and century-old joists demand an electrician who understands how to rewire without destroying what makes these homes exceptional.

Rewiring The Annex's Heritage Homes

The Annex's large Victorian and Edwardian homes were built between 1880 and 1920. Almost all contain original knob and tube wiring — some supplemented by partial aluminum wiring added in the 1960s when demand outpaced the original system. This layered electrical history requires careful assessment before any work begins.

What makes Annex rewiring particularly demanding is the architectural detail that must be preserved. Original plaster medallions, built-in bookshelves, decorative molding, and oak floors are features buyers paid for. Our electricians use minimally invasive techniques — small access holes at outlet locations, careful fishing through walls — that preserve the original fabric of the home.

Annex Rewiring Note: Many Annex homes have had partial rewires over the decades, leaving a mix of K&T, aluminum, and modern Romex in the same walls. This requires an electrician who can assess the full system, not just replace what's visible. Always ask for a full-system assessment before authorizing work.
