Put simply, a "flood cut" is a horizontal cut in a wall with the sole purpose of removing the water-damaged drywall.
When a wall or wall cavity has been damaged by water, such as standing water in a flooded basement, to such an extent that we are unable to simply drill holes in the drywall to dry the cavity, SERVPRO of Glenview technicians perform a flood cut.
A flood cut can be made at 12" or 24" or even 48" above the floor - whatever it takes to remove all the water-damaged drywall. The cut is always made parallel to the floor.
