Whose (Service) Line is It Anyway?
Important information for homeowners about the lines that supply gas, electricity, water and more to houses

Whether you’re a new homeowner or you’ve owned one for years, it’s important to prepare for and protect yourself from the hidden costs of homeownership. Upfront costs like budgeting for a down payment and your monthly mortgage are just the first step. Post-purchase, you’ll need to account for additional expenses like property taxes, homeowners association fees (when applicable), homeowners insurance, and monthly utility expenses to name a few. Homeowners should also plan ahead for the costs of home maintenance – landscaping, HVAC maintenance, among other unexpected plumbing and electrical repairs – and these expenses can pile up quickly.
Take, for example, a service line repair. If you’re unfamiliar with the term, a service line is part of a network of exterior, underground utility lines or pipes responsible for providing water and sewer, electricity and gas functions to a home from a city’s main supply for these utilities. These lines are, for the most part, out of sight and out of mind until something goes wrong. The reality is, however, that if one of these lines break on a homeowner’s property, it’s their responsibility – not the city’s – to pay to repair or replace the faulty line.
The potentially expensive repair costs for a service line can be inconvenient for homeowners and aren’t generally covered under a standard homeowners insurance policy; for example, the average claim payment for a sewer or water line claim is $5,000. Pipe repair or replacement might also require invasive excavation to get to compromised underground lines, which might require digging up your yard, garden or driveway, resulting in even higher costs.
