Most Winnipeg homeowners find out they have knob and tube the hard way: a home insurance renewal that comes back with a condition attached, or a sale that stalls on the inspection report. It is common in the older inner-ring neighbourhoods like Wolseley, River Heights, and St. James, where a lot of the housing stock predates 1950. The wiring worked fine for decades. The problem is what happens to it now.
Knob and tube has no ground wire, so it cannot safely run the three-pronged outlets that modern appliances and electronics need. The original cloth and rubber insulation gets brittle with age, and it becomes a real fire risk when someone buries it under blown-in attic insulation, which traps heat against wiring that was designed to shed it into open air. We remove it properly and replace it with grounded copper wiring that meets the current Manitoba electrical code.
We start by mapping how much of the original wiring is still live. A lot of Winnipeg homes have a mix by now, where part of the house was updated at some point and part still runs on the original circuits, so the first job is knowing exactly what you are dealing with. From there we decommission the old wires and run new grounded cable to your outlets, switches, and fixtures.
The honest part of this conversation is access. Running new cable means fishing it through finished walls and ceilings, and that usually means cutting some drywall to get at it. We plan the routes to keep that to a minimum and we tell you up front where we expect to open things up, rather than surprising you partway through. When the wiring is done, the work is permitted and inspected so you have the paperwork your insurer and a future buyer will ask for.
Not every house needs the same scope. Some homes only have knob and tube left in a couple of circuits and the rest has already been updated, in which case we remove what is left and tie it into the existing modern wiring. Others still run mostly on the original system and need a full home rewiring. Older homes that have knob and tube very often have an undersized panel as well, so a knob and tube job and an electrical panel upgrade are frequently done together. We will tell you which situation you are in after we have looked.
We have been doing this work across Winnipeg since 2019, and removal of old wiring in occupied homes is a big part of what we do. The goal on every one of these jobs is a clean, fully grounded system and a straight answer about scope and cost before we start.
The clearest sign is in the basement or attic, where you can see the original system out in the open. Look for single insulated wires running through white ceramic tubes where they pass through joists, held along the framing by ceramic knobs. If you see that, or if a home inspection or insurance company has flagged it, get it looked at before it becomes an insurance problem.
Many Manitoba insurers will not write or renew a policy on a home with active knob and tube, and others charge a much higher premium for it. Removing it is one of the most reliable ways to keep a home insurable. We provide the permit and inspection documentation that insurers and buyers ask for.
It depends on how much of the original wiring is still live and how accessible it is. A partial removal can be a short job, while a full rewire on a larger or fully original home runs several days. We give you a timeline once we have seen the house, not before.
Some drywall or plaster has to come off to route new cable through finished spaces, but far less than people expect. We plan cable runs to use existing openings and minimize cutting, and we show you the access points before we start so there are no surprises.
Yes. If an inspection or insurer flagged specific circuits, we can remove those and tie the new wiring into your existing modern system rather than rewiring the whole house. We will confirm that the rest of the wiring is sound while we are there.
