Drywall in my house was recently damaged by water, when the fill line to the downstairs toilet failed, filling the 1600 square foot main floor of the house with approximately ½ inch of water. The water soaked up about 18” to 2 feet into the walls. The ServiceMaster guys who responded to this emergency and the insurance appraiser both said that any drywall that had soaked up water would need to be replaced. Both suggested that removing the drywall as high as 3 to 4 feet would not be unusual.
A week later, the contractor is finally getting to the point of removing the drywall, but is only removing what he sees is still wet. He is advising me that the remaining drywall is fine. I am obviously rather concerned at this contradictory information. My fear is that the contractor is trying to shortcut the job, and in so doing could potentially cause the house to lose value or potentially cause problem when applying paint or other materials to the walls.
Is drywall that has been went safe to leave in a house?
