RONCESVALLES K&T SPECIALISTS — Insurance-Approved Rewiring, ESA Permits Handled — Call 647-366-8279
Roncesvalles' Victorian and Edwardian semis are among the most charming homes in Toronto — and among the most likely to carry original knob and tube wiring. Insurance renewal is the most common trigger for rewiring calls in this neighbourhood. We connect you with ESA-licensed electricians who specialize in the sensitive rewiring Roncy homes require.
Knob and tube wiring was standard in Toronto homes built between 1880 and 1940 — and Roncesvalles was built almost entirely in that window. The system uses ceramic knobs to hold wires against framing and ceramic tubes where wires pass through joists. It has no ground wire, runs hot, and was never designed for modern electrical loads.
The most urgent issue today is insurance: most Ontario home insurers now flag knob and tube as a condition of coverage renewal, and some will not issue new policies on homes with active K&T at all. If you're buying a Roncesvalles home or renewing your insurance, a rewiring quote is often the first call to make.
Roncy Rewiring Complexity: Roncesvalles semis are narrow, with plaster walls and original hardwood floors. A good rewiring job preserves both. Our electricians use drill-and-fish techniques that minimize wall openings — typically only small access points at switch and outlet locations, not full wall cuts.
