Strip out laminate & underlay.
Dispose offsite.
Sanitise/deoderise.
Dryout slab (dehum/airmover)
Replace laminate when dry.
Don't lay new laminate until slab has dried sufficiently or laminate could take moisture and split.
If you don't have a damp meter, for floor, tape down piece of rubble sack 12 inches square all four side, leave for 24 hours, and check if moisture is present on plastic, if so humidity is too high, repeat until all clear.
Check other rooms to see if any other flooring is affected, and walls as water quicly moves up plasterwork, behind wallpaper.
