Got home this evening and noticed a crack in dining room ceiling. Started doing some work at the dining table....and realised that I was being slowly dripped on. Got up to examine where the drip was coming from, and found that there's a wet patch about the size of a piece of A4 on the ceiling - gone totally soft, so a finger pokes straight through. Eeek! The bathroom is directly above which is the obvious culprit. So I am guessing I need to get a plumber round ASAP?? BUT - our bathroom floor is tiled, and the sides of the bath are also tiled. Will a plumber need to take up the floor to even see what's happening? And is that the sort of thing a plumber will be able to do? Obviously am keen to solvethe problem first and then deal with the cosmetic stuff after -- but this is one of those moments where I feel very out of my depth with practical domestic things!! Any advice gratefully received...
