yeah no doubt a water leak, they ran a ledger flashing on the deck ledger and butted it up to the edges of the patio door. Water was coming into the basement under the patio door and running down the walls. House was kind of peculiar, foreclosure deal 75% of the sheetrock was removed, unclear as to why, behind the built rite sheathing looked fine, remaining insulation was not discolored and the drywall that backed up to the gutterd areas showed no signs of moisture damage?? I have no idea why they gutted so much. Guy buying thought maybe water damage but that seems like a lot of damaged area with no other evidence of moisture...
