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.
