This has been our specialty since 1996 and we generally always have at least one of these projects
in progress. One of our strengths is that we will take ownership of the patching required to repair
the holes made by the rewire itself. As a result, our holes tend to be more patching friendly and
our projects are completed faster. We will always treat your residence as a home not as a jobsite.

FAQ
Q. What is Knob and Tube type wiring?
A. This is the first generation of wiring in Canada. Shortly after the end of WWII, it was abandoned
for Two conductor/Cloth covered type wiring. Click here to see photo’s. As you can see, this type
of wiring uses ceramic knobs to support individual wires running along the wooden beams, and
ceramic tubes to pass through wooden beams. The connections are done by splicing, soldering and
taping. This is usually well done, however not very accessible for any future repairs/alterations.
Q. Why is it unsafe?
A. There is no ground wire. This presents a shock hazard, and could lead to an electrical fire. It has
no temperature rating. This is why the wires above ceiling mounted fixtures are so commonly
compromised. It is a free air wiring system and was never meant to be covered by insulation.
