Document source clues without opening walls
Note fixture use, drainage use, weather and whether the water appears when no fixture is running.
Contaminated water changes the response
Sewage or other contaminated water deserves experienced professional cleanup and repair rather than ordinary DIY drying.

Restoration is a separate scope
Plumbing repair may not include drying, cabinet, flooring, drywall or finish restoration.
