This is clearly shoddy installation work, which leaves me with a gazillion questions. Like someone else said, what else did this contractor install? I would think that ANYTHING they installed would have to be checked now, particularly the wall-mounted TVs and the Murphy Beds. And how in the world did this pass inspections? What else did inspections miss? Hopefully this was just a one-off and it doesn't snowball. But man, I would be SUPER worried if I was in charge right now.
