Snaking wire thru wall with minimal damage.

I had a door bell installation recently. The outer wall is brick. First I drilled a hole from the outside in (measuring of course the height of this light switch first). Once that hole was exposed in the wall behind where the door bell was going to be installed, i took my drill bit and angled it up inside the same hole that I had drilled from inside. There I was able to send my snake up the wall to the drop ceiling where the wire had been run.

Once the snake was in place I was able to fish my wire down the hole. (I did have to open the hole a little bit to allow the snake with the wire taped to it to pass thru, since my hole was so small) 

Once this was accomplished all I had to do was pass the wire straight thru the hole to the outside so that I could install my door bell. 

I did not take photos of everything else, as I was short on time, and well... I do still have to eventually return to this install when the internet is working to make sure everything is set up properly. Oh yeah, and finish wiring the relay for the door buzzer.
