Ownership stops at the property line, not the meter
The water line from the street to your house, the sewer lateral running out to the main, and the buried electrical service are generally the homeowner’s responsibility. A failure means excavation across a driveway or a yard, and the repair commonly runs into thousands before anything is restored above ground.
A standard homeowners form excludes it
Wear, deterioration and the failure of underground pipes are outside the usual cover. The policy may pay for resulting damage inside the house while paying nothing to find, dig up or replace the line itself, which is the larger part of the bill.
Service line cover is cheap and specific
Many carriers offer a service line endorsement for a small annual amount with its own modest deductible, covering excavation, repair and restoring the landscaping afterwards. It is one of the better value endorsements available and it has to be asked for.
