Start with the problem you want solved
Describe the visible evidence: dripping, a damp surface, water-meter concern or staining that appears after a fixture is used.
Kearns: planning the visit
For a recurring drain issue, record which fixtures back up first and whether the problem follows laundry, shower or kitchen use. That sequence helps distinguish a local obstruction from a broader drainage concern. Ask what the diagnostic visit includes before approving a cleaning method or a larger excavation.
