Old settlement, younger houses: what's really in Loyalist Township's walls
Knob & Tube Kingston covers Loyalist Township — Amherstview, Bath and Odessa, just west of Kingston along Bath Road — and it's the one area where we start by telling homeowners their problem is probably not knob and tube. The settlement here is genuinely old; Fairfield House in Amherstview dates to 1793 and is among the oldest houses in what was Upper Canada. But most of the housing people actually live in is far younger: postwar subdivision stock from the 1960s and 70s, built two decades after knob and tube's era (roughly the 1880s to the 1940s) had already ended. So when an insurer or home inspector flags "the wiring" in Amherstview, it pays to ask: flagged for what, exactly?
The 1960s–70s subdivision: aluminum wiring's home turf
If your Amherstview house went up between roughly 1965 and 1976, the flag on your file is most likely aluminum branch wiring. Copper prices spiked in that decade, builders switched to aluminum, and the problem showed up later at the connections: aluminum expands, contracts and oxidizes where it meets outlets, switches and breakers, and loose connections overheat. Insurers treat it much the way they treat knob and tube — refusals, surcharges, or conditions — but the remedy is usually cheaper: full replacement is one option, and copper pigtailing of every connection under ESA permit is often the accepted alternative. The same era left many homes with original 60-amp or minimal 100-amp services, and insurers flag undersized panels — along with Federal Pacific and Stab-Lok equipment — on the same letters. A panel upgrade to 200 amps clears that item and buys capacity for EV chargers and heat pumps at the same time.
Bath and the older pockets: where knob and tube is still real
The genuine knob-and-tube territory in Loyalist Township is the older stock: Bath village, whose core holds some of the area's earliest homes, plus century farmhouses along the Loyalist Parkway and pre-war houses scattered through Odessa and the township's rural roads. In those buildings the classic rules apply — ungrounded conductors in aging cloth-and-rubber insulation, unsafe when buried under blown-in attic insulation, and frequently spliced into by decades of renovations. Our guide is knob and tube safe? covers the warning signs, and the removal page covers how a rewire actually proceeds: cable fished through existing cavities under ESA permit, small patched openings, 3–10 working days for most homes.
One assessment, whichever decade built your house
The practical answer is the same licensed assessment regardless of era. A partner electrician identifies what's actually in the walls — knob and tube, aluminum, mixed circuits from staged renovations — checks the panel, and produces a free written quote for exactly what your insurer's letter requires. For true knob and tube, budget $3,000–$6,000 for partial replacement, $5,000–$8,000 for a full bungalow, $8,000–$15,000 for a two-storey, and $14,000–$25,000 for a large century home with a 200-amp panel; aluminum pigtailing and standalone panel upgrades typically land well below those figures. Full ranges are on the cost page. Every path ends the same way: an ESA Certificate of Inspection to your insurer, conditions lifted, standard rates restored — often a difference of $500–$1,500 a year, as our insurance page explains.
Not sure which problem you have? That's normal — mixed-era wiring is the rule in this township, not the exception. Request the free quote and note the approximate year your house was built; the assessment sorts out the rest.
