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
Standing water, wet insulation, wood moisture, drainage, and crawl-space drying.
Independent guide. Service availability depends on the property location and the type of damage.

Crawl-space water can affect insulation, ducts, framing, subfloor, odor, and indoor humidity. Drying matters, but the plumbing, grading, gutter, or groundwater source must also be addressed.
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.
Written scope
Crawl-space work should distinguish the water source from its effects on soil, vapor barrier, insulation, ducts, framing, subfloor, and indoor humidity. Drying without source correction leaves the same path open.
