some water stain on the ceiling. Should I open the ceiling or not?
Recently 1 week when we have stopped to use the shower room and were re-sealing the shower room, we found there is some water stain on the ceiling of first floor and just under the shower room.. (we painted the ceiling 1 year ago). The water stain is dry since we have stopped using the shower room for 1 week. But in the middle of the stain there is a 1 inch size place which is soft when pushing it by finger.
Don’t know where is the leak. I guess maybe leakage come from the failure of sealing in the shower room or the crack in the grout between the tile. We plan to fix the sealing and the crack by ourselves to see whether the leakage can be stopped.
How do you think about the reason of the leakage source?
The other problem is should we open the ceiling to remove the possible mold?(we don’t know whether there is mold. However the leakage happened for at least several months). Someone told us if the leakage stop, there is no need to open the ceiling becasue the mold will die without water. But someone told us it is necessary to open the ceiling to remove the mold.
