This area was the result of a slab leak. Unfortunately for the customer, they just finished remodeling the entire area. SERVPRO of Huntington Beach arranged for a plumber to come out and bypass the leak. They also set up some specialty equipment that saved most of the flooring.
The customer had extra planks from recent installation so they were able to replace. By waiting any longer to make the call, there would have been much more damage to the flooring.
Even if you suspect a problem, give SERVPRO of Huntington Beach a call as the inspections are free during normal business hours.
