I recently purchased a home built in the 1960s. While doing
renovations, I got an electrician out to inspect my wiring. He said it
was fine, and wasn't worth rewiring the entire house, but I have no
grounding, which he said meant surge protectors wouldn't work. He said
to add grounding, he would basically need to rewire the whole house,
which would cost about $12000. Is it possible to ground just certain
outlets and/or to get "grounded" in a less costly manner?

Thanks!
