Hey y'all!
Lots of good advice here, so I'm hoping you can help me with my floor. Outside the bedroom door the planks didn't line up great and it didn't bother me until I was done. So this is a board in the middle of the floor locked in by two bedrooms and a stair landing. As you can see in the video, it's a little loose around the edge and I think the floor underneath must be uneven. I was wondering if I could inject something underneath it? I'm really lost here and don't know what to do. But, I'm afraid if I don't do something it will not only bother my wife, but it will catch on something and tear the floor up. Any suggestions are appreciated.
