Sorry I know this isn't what this board is for but I have some serious questions about wiring in a house I am looking to buy. It has knob and tube wiring built in 54 so new to have that but not out of the ordinary here in NE Ohio(Cleveland). Looking to talk to someone about replacement costs and whether or not it really needs replaced. Have a guy coming to look in a few days but thought I'd see if anyone here had any input or experience with this.
