Knob and tube wiring

Quick question: I have some K&T wiring in my home, but in some places it lacks the tube that goes through the joist. I do plan on replacing but can't afford it presently. Do I have a serious problem with the wire going through the joist without the tube? Or do you think it will be okay for now?

If the joist is dry wood it should be ok. Replacing the entire run to the box would probably be the only code acceptable fix. Does the insulation look OK? Just touching the insulation could damage it so I'd just leave it as is if it looks ok.

It's not correct but it has probably been that way for at least fifty years so as long as no additional loads are placed on the circuit I would agree with Ray to not touch it and just replace as soon as you can afford to.

thanks guys, I think I'll just leave it alone for now the insulation does look pretty brittle though but I don't plan on touching it until I'm ready to replace it.

That's the best policy with K&T. Don't touch it until you're ripping it out to recycle the copper.
