Updating knob and tube

I know we paid 0 for the guy to hook everything up to the new boxes, and a few hundred for an afternoon that one guy spent in our attic.

Knob and tube electrical wiring involved stringing individual insulated electrical wires across porcelain insulators ("knobs") which were nailed to the surface of wooden framing members.When electrical wires needed to actually pass thru wooden framing members, the electrical wires were strung through porcelain insulators called "tubes" which protected the wires.The first insulation was asphalt-saturated cotton cloth called "loom".It appears that every one thinks that you have to rewire a home because it is 2 wire only, fact is you do not unless it is a real fire hazard, broken or bad wiring etc.The code even still to this allows you to repair knob and tube wiring.

I know that old houses are a can of worms, and this house certainly would be as it needs a lot of repairs.

The funny part of all this was when he mentioned to my parents this plan of proposal and my mom said, 'Can't you just do it over a nice dinner? She'd expect nothing less from me.'" —Heather, 37Follow Lane and Hannah on Twitter.
