I live in a flat on the second floor. The building in which I live is five levels high. How do I find out if the mildew on the bathroom ceiling comes from the upper floor? I removed the mildew just a few months ago, but it suddenly reappeared. Apparently there aren't any broken pipes, but we are not sure. Any ideas?
Is the mold concentrated is a small area or cover most of the ceiling? Do you notice water condensation on any surfaces after using the shower? If the morror fogs or the tiles feel wet your shower is the most likely cause. If it were from a leak upstairs you should see ceiling discoloration in an area ajacent to the leak. If your bathroom has a vent fan or window use it. Leave the door open to allow air to circulate after showering. If you can paint the ceiling with bathroom specific paint as it contains a mildewcide. The fix is to control the moisture so that the mold can't start.
