It may not look like much water
There's nothing like waking up first thing in the morning, walking out of your bedroom and into a pool of water in your hallway. Next thing you know your socks are wet, and you just realized today might be considered a bad day. First thing anyone does in this situation is figure out where it came from. You discover that you have a broken water line to the vanity sink in your bathroom. You turn off the valve right there under the sink and stop the water and call your plumber to come fix it. That's not the end of the issue yet.
So, the plumber is on his way and you're looking around at all this water on the bathroom floor, your carpeted hallway is soaked and of course there is still water dripping out from the vanity. This is a mess most people don't know how to handle, a few towels and the dehumidifier out of your basement might not be the answer. The common reaction to water everywhere is to get some towels and maybe a fan or two.
When it comes to large amounts of water, towels and fans are not going to be enough to dry things below the surface. Once water has saturated a carpet down to the pad, the sub floor is now affected. Same for walls, the outer layer of drywall being saturated means that most likely there is wet framing studs that are at risk of being wet as well. With the knowledge, you now know the next call should be SERVPRO.
