I need a staircase to be completely removed and a new one put in. I believe I need a joiner for that. However, I also need a wall put up (is it a stud wall, that's called?) behind it to close off an area that now won't be accessible with the staircase in front of it, and knock a hole in a wall in another room, and put a door in, so we can access it another way.
Can a joiner put up a (stud?) wall, knock a hole and put in a new door? It would be great if I just needed to book one person in!
