If your home was built before 1950 — the older sections of Aurora, the heritage stretches of Newmarket, the farmhouses out around East Gwillimbury — there's a real chance you still have knob-and-tube somewhere in the walls or attic. It was the standard for decades, but it can't be insulated over, it wasn't designed for modern loads, and most insurance companies won't write a new policy on a home that still has it active. Tim's worked through dozens of these projects, including one 1920s farmhouse near Holland Landing where three other electricians said the only way through was gutting walls. He worked it room by room over three days and the plaster stayed up.
What it costs
Transparent pricing in writing.
A full-house K&T removal typically runs $8,000 to $15,000 depending on size and accessibility. Partial removal — attic only, or a few specific circuits — usually runs $3,000 to $6,000. Tim quotes after the inspection and the price holds unless scope changes.
Before & after
What we replace. What we leave.
What we typically find
- Insurance company won't write or renew on the home
- Can't insulate exterior walls because the K&T is still active
- Buying or selling — buyer's inspection flagged it
- Circuits overloaded, breakers tripping constantly
- Planning a renovation that needs new electrical anyway

How We Handle It
Room by room, no gutting.
Tim inspects the entire home first — attic, basement, accessible wall sections — and maps which circuits are still on knob-and-tube. Then we put together a phased plan. Most jobs run circuit by circuit, fishing new NMD-90 through existing wall cavities, opening drywall only where access genuinely requires it. ESA permits get pulled, inspections scheduled. When we leave, your walls can be insulated, your insurance company has the paperwork they need, and the wiring inside your walls is good for the next 50 years.
Knob-and-tube removal is not a weekend project. It involves live circuits, opening walls in occupied homes, and getting the new wiring fished cleanly through existing structure without making a renovation out of it. In Ontario, this work requires an ESA permit and a licensed electrician. Tim's done this in plaster homes, post-and-beam homes, and balloon-framed farmhouses. The plaster stays up.

FAQ
Common questions
How much does knob-and-tube removal cost?
Full-house removal typically runs $8,000 to $15,000 depending on home size and how accessible the existing runs are. Partial removal — say, just the active circuits in the attic — can be $3,000 to $6,000. Tim quotes after walking the house, and the price holds.
Will you have to open my walls?
In most cases, some wall access is needed — but Tim fishes new wire through existing cavities wherever possible to minimize patching. He'll tell you upfront which walls need to be opened. The plaster stays up in places it can stay up.
Can I insulate over knob-and-tube?
No. Ontario Building Code prohibits insulation in contact with active K&T wiring because of overheating risk. Once we've replaced it, your insulator can fill the cavities.
Will my insurance company drop me if I have K&T?
Many Ontario insurers won't write new policies on homes with active K&T, and some won't renew existing ones. Removing it resolves the issue. We provide the ESA inspection documentation for your insurer.
