About a year ago we had a contractor switch out a cabinet for a pedestal style sink. I didn't notice until recently that behind the sink there was a loose ring object on the outflow pipe and the molding (did I get that right?) is loose
The top red circle has a loose ring around it, what is that called? If I push it against the wall it doesn't fit in the hole. It does not look like it was glued on initially. How should I fix it so it covers the hole?
The other red circle at the bottom. Do I need to hammer a nail into that molding to get it to stay against the wall and spackle/paint over the nail?
