Electric retrofit and sheetrock

[James H.]

I am looking at a house that has knob and tube wiring. To replace the wiring it is much cheaper if I demo the sheetrock myself. When you demo sheetrock, do you try to save baseboard, window and door trim, or do you just replace.

If it has knob and tube, in my area you will have lath and plaster for wall materials.
