I assume that you probably won't write back but .....,

What are the walls made of? Is it an old house? Are the walls made of
plaster over wooden lath? Are they made of some other type of masonry
product?

Cutting electrical
outlet holes and ceiling holes is very difficult. Using a saws all
with a big tooth demolition blade, I get maybe 20 inches before the
blade is flat. Ceramic blades are much worse. Am I doing it. Right?
I find finer tooth blades are worse.
