Where the water heater sits matters
A tank in a garage or an unfinished lower level mostly wets concrete. A tank in a closet on a finished floor soaks the subfloor, the walls around it and the carpet next door. A tank in the attic is the worst case: water runs through the ceiling and into the rooms below. A drain pan with a working drain limits all of this.
Hot water and finishes
Hot water from a tank failure softens vinyl flooring adhesive, swells laminate and particleboard cabinets fast and carries more moisture into the air. The crew extracts first, then removes base trim and checks the walls and subfloor with meters before setting the drying.
After the tank is replaced
A plumber replaces the heater; the drying team dries the closet, the floor and anything below. Drying runs until readings reach the goal. For efficiency and replacement options, see Energy Saver, and the CPSC lists water heater recalls.
