rewiring house with plaster walls

Does anyone know an easy way to rewire a house with plaster walls without cutting into the plaster. I should be ok with second floor cause i think there is access in the attic for me to fish, but the first floor has plaster walls and ceilings and i didn't want to gut it out and redrywall if i didn't have to. thanks for the feedback

Does the house have a basement? I've had pretty good success getting new cable into walls for outlets from the basement. Invest in at least a 54" flexible drill bit, and definitely get the guide tool for it as well. You can guide the bit through an existing cutout where an outlet box was, and drill down through the bottom plate to fish wires. The bit even has a hole in the tip to clip a pulling grip to, so you can drill down, attach new cable to the bit, and pull it through. You'll also want to get a couple fish tapes.

Wiring through the ceilings is a bit trickier, but not too bad as long as you're running parallel to the joists, rather than perpendicular.

If you don't have a basement, things get a bit harder...

have you considered the baseboard trim? if its big enough, and you can remove it without too much damage, you can run your new wiring right above the floor plate, behind the baseboard trim. You will still have to fish wire up to outlets, fixtures, and switches, but still less damage to the walls in the long run.
