I just bought a new (old) house and I have a couple of questions. Our

Do I have to remove all of the dead knob and tube wiring?

The second question is:

I'm running armoured cable to the attic to replace the Knob and Tube
and the cable is running in an open cavity between two bedrooms. Do I
have to open the wall and secure this every four feet?

Thanks,

Are you sure you want to replace it? Really. K&T is a very good
wiring system. You would not put any new in, but assuming what is there has
the capacity for what you need, why replace it?



Agreed. Seems most of the impetus for replacement comes from anal
insurance companies and their threat of policy cancellation.


Wellllll... most K&T is not rated to have insulation blown around it,
so that pretty much mandates replacement in exterior wall cavities, in
my book.
