Broken pipe

One day I received a call that my apartment is flooding. I was asked to come home as soon as possible. Once I arrived I found out that a pipe under my kitchen sink had broken and water leaking on the floor for some hours. The leak was discovered because water was dropping to the street from my balcony. I was naturally concerned about the damage caused by the water and also about possible mold issue in the future. I was thinking that some company specialized on drying flats would be needed. To my surprise all Spanish were saying that the mold will not be an issue and just opening the windows and doors will dry the wetness. Apartments in Spain do not have isolation materials which might get wet like in Finland. In Finland it might be necessary to tear down some walls after such leak but apparently it is not needed in Spain.
