Were you extreamly lucky or just THAT GOOD?
Honestly, I'm that good. As long as I have a wall opening in a bay that is lined up with the ceiling bay, I can use a long flex-bit with aiming handle to penetrate the top plate. Then thread a fishtape through that hole, with the end gently curved in the right direction.
I have a flexible flashlight that hangs inside the wall and points up, and a mirror on another flex handle, making it easier to get the fishtape through the hole. I put some white tape on the fishtape to make it easier to see where the tip is.
Let's say I have a livingroom off the foyer, with a second doorway to the dining room. There is a switch by the first doorway, but it's on the 'wrong' wall. I add one, often placed next to the second doorway, and convert the original switch into a 3-way pair.
Now, if the house has vinyl siding, everything is easier. I have been known (don't tell anyone; it may not be compliant) to run UF behind siding, out through the band joist, up the wall, and back in, penetrating the ceiling bay from the outside.
Of course, I seal the holes with caulk or expanding foam. The toughest fan box I did happened to have a bay window with copper roofing in line with the ceiling bay, so I had to get
really creative. I suggested adding a recessed light in the top of the bay-window ceiling. They liked it, so...
I drilled into the bay window's "attic" space from the fan box's 4" hole, and working through the recessed light's 4" hole, managed to run the 14-3 from the room's ceiling box, through the hollow area over the window, into the wall beside the window, down into an old-work box, where I fed the new switches from a receptacle below.
No access holes (other than the recessed light), no patching, and it looks like it was built that way. On the rare occasion I do have to make holes, I take care of it myself. I've done plenty of drywall work, from repairs to entire rooms, so it's a handy skill. In fact, three years ago, we built an entire addition. We're licensed for home and commercial improvement, too.
