Homeowner finds rotted wood and rusted pipes under bedroom carpet

A homeowner who ripped up a "wonky" bedroom carpet discovered rotted wood, rusted pipes, and old concrete beneath, prompting a Reddit inquiry about whether the damage could be patched or required full removal. The find suggests a potentially serious structural issue in the downstairs room. The homeowner reported the floor had always felt uneven, and after tearing up the carpet, they found soggy moldy particle board and old dry-rotted wood over rusted pipes in concrete. Reddit commenters suggested the space may have been an enclosed paver patio, with one recommending jackhammering and redoing the foundation while addressing possible soil movement or tree roots. Others advised caution, noting the need to identify the cause before repairs, including checking if pipes are active water lines and whether the visible grid could be post-tension cables, which should not be cut without professional evaluation. The thread highlighted broader concerns about hidden home problems and the importance of proper diagnosis.
