First thing to do is not panic. Walls and ceilings can be dried in place as long as they are not falling down or caving in. A restoration specialist can dry walls and ceiling in place on any clean water flood. Do not allow a company to cut drywall or tear out ceiling unless the integrity of the drywall is in question.
