Service Line Coverage
Provides peace of mind for your water, gas, electric, and sewer lines.
What is service line coverage?
Service line coverage is an optional type of homeowners insurance that helps pay for repairs or replacement of underground utility lines that run from your home to the public utility connection, such as water, sewer, electrical, or gas. Standard homeowners insurance typically doesn’t cover these lines, which means if they fail or get damaged, you’re responsible for the full cost.
Whether it’s a broken water pipe, tree roots invading your sewer line, or damage to a buried power cable, service line insurance can save you thousands in unexpected repair costs.

What is service line damage?
Service line damage refers to physical harm, deterioration, or failure of underground utility lines—such as water, sewer, gas, or electrical—that connect your home to public services. Common causes include root intrusion, ground shifting, corrosion, wear and tear, and extreme weather events like freezing.
Service line damage typically occurs unexpectedly, and most homeowners insurance policies don’t cover these repairs.

What does service line coverage cover?
Service line coverage offers up to $10,000 per occurrence for damage to your exterior underground service lines, including:
- Water piping that connects from the dwelling or other structure to a public water supply or private well.
- Sewer piping that is part of a sewer lateral that connects from the dwelling or other structure to a public sewer or private septic system.
- Ground loop piping that connects to a heat pump.
- Heating systems piping, including geothermal, natural gas, propane, and steam.
- Compressed air piping systems that transport air from a compressor to various applications.

These covered lines fall outside what most standard homeowners policies protect, which may leave you surprised when you face costly out-of-pocket repairs. That’s where extra protection like water pipe insurance, sewer pipe insurance, and gas line insurance coverage becomes invaluable. If you rely on a private septic system, having septic system insurance coverage can help offset unexpected repair bills. Likewise, water main insurance and water service line insurance coverage can save you thousands when damage strikes underground.
