It s not enough that you treat it as a frustration and annoyance.
Water leaked through floor.
Usually a short term one time wetting like this does not cause damage to the framing just water stains it but usually the water evaporates well enough just through the wood and drywall to the household air to prevent noticeable mold or mildew growth as long as the surrounding environment is kept reasonably low humidity and airflow is keep high.
You re most likely to see wet flooring near major appliances that use water washing machine dishwasher or in the bathroom near the sink toilet or shower.
Water leaks can happen under various types of flooring.
Spread a plastic drop cloth over the floor beneath the dripping or water damaged area.
Moisture and water seeping through a concrete slab floor.

They may be mold blackened and you may even see water dripping.
Go into the crawlspace under the floor and look for signs of moisture on the joists.
With a drill and 1 2 inch twist bit drill a hole in the center of the damaged area.
Next make sure the water is coming up from the basement floor and not falling onto it from the pipes above.
If there is active dripping drill at exactly the spot where the water is dripping.
Finish cleanup by mopping hard floors but leave water damaged carpets and padding to the restoration crew.
Place a bucket below the damaged area of the ceiling or where dripping is occurring.
If given enough time a slow leak can result in very serious structural damage that will make the restoration process longer and more expensive.
Hidden water leaks behind walls can be especially dangerous because the water will get absorbed into flooring drywall and ceilings as well as wooden support beams and sheetrock.
You have to treat it as an emergency.
