Ok everyone who has tackled this mess-what is the best way to replace knob and tube wiring without gutting the house??? Can I expect that there is some under the over 100 year old floor boards?? What should I expect to pay to have an electrician do it?? I've had bids from $2000 to $10,000. The highest bid came from a union electrician who probably didn't want to do it! lol. The lowest bid came from a retired union electrician.

I have uncovered newer wire connected to the knob and tube inside most junction boxes. HELP!!
