Bathroom drain leak Cincinnati, OH

A failing drain stack transition in the 2nd floor bathroom sent water migrating through the floor assembly into the kitchen ceiling directly below — saturating joists, cracking and delaminating plaster across the ceiling plane, and wicking into wall cavities. Moisture readings reached 306 on the pinless meter. H2O Restoration was on site to document, open, and begin drying across both affected floors.

PROJECT OVERVIEW

A leaking ABS-to-PVC drain stack coupling in the 2nd floor bathroom had been sending water through the floor assembly long enough to fully saturate the kitchen ceiling below — spreading laterally across joist bays, cracking and delaminating plaster well beyond the drain footprint, and staining the exposed framing with the dark discoloration of an extended or recurring leak. When H2O Restoration arrived, pinless moisture readings of 306 and 194 confirmed saturation across two separate zones of the kitchen ceiling, both far above dry standard, and the opened hallway wall on the 2nd floor revealed the Fernco coupling with visible debris accumulation at its base — putting the origin beyond doubt and giving the insurance file exactly what it needed.

Water had migrated from the 2nd floor drain stack through the full floor assembly, saturating ceiling framing across an area significantly larger than the drain footprint. Crack mapping on the kitchen ceiling confirmed lateral travel within the joist bays before any visible surface damage appeared — meaning the scope extended well beyond what was initially visible.
