Does anybody have any idea what could have caused this or how it could be remedied? We have had driving rain with heavy duty wind for a few days now but I just don't know how the water could be getting in I can't see or feel any gaps in the seal and the window sill is dry.
Things are further complicated by being 15 storeys up in a flat so checking externally isn't possible. The walls are solid concrete.
Any advice on how to dry it out would also be welcome. (pic below to show what it looks like)
Thanks!
