Cheers for the comments and help, I think maybe I had picked something a bit too hard trying to connect those skirt boards.
Thanks Chris, it nearly worked, but think I maybe need to know more about the settings etc before I manage to join them (The scale keeps going out when snapping)
Anyway It may not be noticeable so will come back to that if I get the time.

Here's an update, looking both way's from top hallway.
