Corelz125- it was such a long and painful process!  Dealing with the kitchen and laundry, and moving appliances was an added "fun" 🙄.  Much better to do an open room.  

Pottz - yes, I'm guessing some of my stress points would have been covered or caulked by someone  working on the clock.  Also, I read of floor joints failing - I'm guessing they were never "fully" connected.  There can be no bounce in the plank.  And yes, I actually took a flashlight at floor level to ensure some stubborn sections were truly together.
