Prepare a useful arrival brief
Describe the condition without promising a diagnosis: what moved, when it started, which fixture use preceded it, what private control was used, and whether the result held. Mention tenants, pets, locked areas, stairs, parking, and damaged finishes. Photograph the wide view, first wet point, labels, and any safe meter display before cleanup changes them.
Do not enter sewage, open heater or electrical panels, return to a suspected gas area, force valves, dismantle a fixture, or open finished surfaces to make the story more convincing. The provider should earn permission for invasive diagnosis by explaining the evidence, access, stopping point, and how the opened area will be protected.
Keep the town boundary explicit. Water at the curb, meter equipment, a public main, street flooding, or public sewer overflow needs Walpole Sewer & Water or emergency direction. A property-side provider should not represent that it controls town valves, dispatch, billing, service restoration, or public repair.
Before normal use resumes, ask what remains isolated, which fixtures must stay off, what test was completed, and whether inspection, drying, sanitation, electrical clearance, or a second repair phase remains. Write those restrictions where every occupant can see them and preserve the handoff time.
