Plumbers....urghhhhh!!

Hi,couldn't really get to write in the blog for the past few days.......
I had a problem(major)with my plumbing in the upstairs bathroom...water dropped from the ceiling of the bathroom downstairs.We got the contractor who always fixed things around the house and did odd jobs like fixing a hole in the wall,painting the whole house.He brought a plumber along and they removed the whole floor and renewed all the pipes in the upstairs bathroom.next thing we knew the lower bathroom started leaking from three more places!!
The guy said it'll take a few days and dry up and everything will be fine and dandy,well its been three days now and it's still dropping big drops!!
What more can we do ...changing all the plumbing and putting down new floor tiles??isn't that all enough.....
