Correct the cause
Identify who will stop the plumbing leak, close the roof opening, correct drainage, or address the moisture source. Confirm whether that work is included or requires a separate specialist.
Water damage
Leak-path, safety, drying, and repair questions for stained or sagging ceilings.
Independent guide. Service availability depends on the property location and the type of damage.

Stay clear of sagging drywall and wet fixtures. The visible stain may be smaller than the wet area above it, so the source, insulation, framing, and rooms around the leak should be checked.
Compare the scope
Identify who will stop the plumbing leak, close the roof opening, correct drainage, or address the moisture source. Confirm whether that work is included or requires a separate specialist.
Ask what will be extracted, removed, cleaned, contained, dried, or monitored; which equipment is planned; and how changing conditions will be documented.
Before finishes return, request completion evidence appropriate to the job—such as moisture readings, photographs, cleaning records, or a written explanation of materials removed and retained.
