I'm getting started on a fixer-upper.
It's a two story house with some very old wiring. The upstairs is going to get gutted and new sheetrock so I'm OK with wiring that. The downstairs has previously been somewhate remodeled with sheet rock over the old lathe and plaster. However, the old wiring was left in place with a few exceptions in a bathroom and a little in the kitchen. I've helped the previous owner (my father-in-law) replace a few light switches and found the insulation to be very brittle and fall right off the wiring. I want to do all new wiring since the place needs an upgraded panel anyway. I can probably get new wires up between the walls for the outlets but I'm wondering how I'm going to pull new wire for the lights.
I know a guy that spliced the new wire to the old wire and pulled it through. I can't imagine how you'd get the splice around the corners.
How do the pros do it? Remove small sections of sheet rock?
