Record the pattern
Note whether the condition follows rain, plumbing use, or another event. Provide earlier repair records and observations from adjoining rooms or units. The timing can help the assessor decide what to investigate without turning an owner observation into a diagnosis.
Understand the investigation tools
Moisture readings can help assess building materials. Infrared images show surface-temperature differences and may guide where further checks are needed; they do not see through a wall or independently confirm water.
Ask what happens before opening
- What source and affected area are suspected, and what evidence supports that view?
- Are concealed utilities or possible contaminants relevant to the access plan?
- Who will document the findings and confirm the source repair before the wall is rebuilt?
