A pre-trip check cannot guarantee a leak-free home, but unresolved leaks and unclear reporting arrangements are worth addressing before leaving. Follow manufacturer and qualified trade guidance rather than blanket internet advice about shutting down building systems.
Resolve known concerns first
Arrange evaluation of recurrent dampness, appliance leaks or an AC drainage concern. Do not perform electrical or invasive repairs as part of a quick checklist. Keep source-repair records and ask the relevant professional what operation is appropriate while the property is vacant.
Make reporting and access practical
Give a trusted contact a clear way to report visible problems and authorized access arrangements. If using leak sensors, verify installation and notifications according to their instructions. Do not assume that a device or an untested message alert guarantees protection.
Keep useful information available
Maintain insurer contact information, building contacts and the normal supply shutoff location where appropriate. Ask your insurer about vacancy conditions under your own policy. After a reported problem, prioritize safe assessment instead of asking someone to enter standing water for photos.
