What Is a Service Line Warranty?

A service line warranty, or utility line warranty, offers homeowners protection against unexpected repairs or replacements of water, sewer, electric, or gas lines. These warranties function similarly to home warranties, with policyholders paying monthly premiums to a provider. 

In exchange, the provider agrees to evaluate reported damage, dispatch technicians for assessment, and cover some or all repair or replacement costs for validated claims.

It’s common for property owners to think their local utility companies are responsible for maintaining and repairing service lines within their boundaries. In most cases, homeowners have to pay for service line repairs and replacements.

By investing in a service line warranty, homeowners can mitigate the risk of major out-of-pocket expenses related to underground infrastructure issues.


What Does a Service Line Warranty Cover?

Service line warranties cover some or all of the cost to repair or replace a damaged underground utility line. Damage might include leaks, clogs, broken lines, or age deterioration.

Covered costs usually include labor and materials. Excavation expenses are typically included, as accessing underground lines can require significant digging.

Most policies also cover basic property restoration after repairs, such as filling excavated areas and replacing sod and other basic landscaping. 

The warranty generally extends to the specialized equipment required for repairs or replacements and covers one or more of these service connection types: 

  • Electrical lines
  • Fiber optic cables
  • Gas lines
  • Sewer lines
  • Water lines

Many providers offer 24/7 emergency repair services for urgent issues, ensuring prompt attention to critical problems. 

Some policies offer additional benefits, such as coverage for damage caused by tree roots or freezing, hotel accommodations if repairs render a home temporarily uninhabitable, and protection for outdoor systems such as sprinklers or septic tanks. 

What Is Not Covered by a Service Line Warranty

Like most home warranties, a service line warranty usually spells out exclusions or damage not covered by the contract. Exclusions might include the following: 

  • Damage that existed before the contract was signed
  • Damage caused by misuse or neglect
  • Lines that are not in compliance with local building codes

Before committing to a service line warranty plan, review the terms to understand what is and isn’t covered.

How To Spot Service Line Damage

Stay alert for signs of damage across various types of service lines. In addition to broken pipes, leaks and other damage could affect multiple components, such as pipe couplings, brackets, clamps, clips, and other buried hardware.

For water lines, signs of unseen damage include unexpectedly high water bills, pooling water or damp spots in the yard, low water pressure, discolored or rusty water, and sounds of running water when no taps are open.

Sewer line problems may manifest as slow-draining fixtures, gurgling sounds from drains, sewage odors in or around the home, unusually lush lawn patches, or sinkholes and yard indentations. 

Signs of gas line issues include a gas smell inside or outside the home, dead or dying vegetation near gas lines, and hissing sounds near gas appliances or meters. 

Electrical line problems can cause flickering lights, frequent circuit breaker trips, warm or discolored wall outlets, and buzzing sounds from outlets or switches. 

If you spot any of these signs, contact the appropriate professional as soon as possible. If your service line warranty covers the affected component, contact your provider to file a claim.


How Much Does a Service Line Warranty Cost?

Based on our research for 2024, service line warranty providers usually charge $5–$24 in monthly premiums.

Other cost factors include your deductible or service call fee, your coverage limits, and the potential out-of-pocket costs for repairs or replacement jobs not covered without the warranty.

The following factors also influence service warranty costs: 

  • Coverage level: Comprehensive plans covering more than one type of utility line can cost more than coverage for a single line type.
  • Location: Homes in older neighborhoods or exposed to extreme weather might cost more to cover.
  • Property size: Larger homes with longer or difficult-to-access utility lines might cost more to cover.
  • Material: The materials used for your utility lines (high-density polyethylene pipe, PVC pipe, copper, fiber optic lines, etc.) can also affect the cost. 

Some providers offer discounts or additional perks, such as higher coverage limits, with plans that cover multiple service lines.


Benefits of a Service Line Warranty

A service line warranty’s benefits are unique to each customer’s circumstance and whether they have any coverage through other warranties or insurance policies. 

One benefit is peace of mind. A service line warranty offers protection against unexpected and potentially costly repairs, which can cause financial strain. This assurance makes property owners feel more secure about their ability to afford expensive repairs.

Convenience is another benefit. Many warranties include 24/7 emergency service and handle the coordination of contractors, unburdening the homeowner during an already stressful time.

Additionally, warranty companies typically maintain networks of licensed, experienced contractors. This ensures expert service when issues arise, leading to higher quality repairs and more lasting solutions to service line problems.

Another benefit is potential cost savings. A single major repair could easily exceed the cost of several years’ worth of warranty premiums. This financial protection can be particularly valuable for older homes or properties with aging service lines, where the risk of failure may be higher.

The value of these benefits varies, depending on the age and condition of your property’s infrastructure and your ability to pay for repairs without warranty assistance.


How Does a Service Line Warranty Work?

A service line warranty works like most home warranties or insurance policies. Customers pay a premium, and in exchange, the provider covers certain damages up to a specified dollar limit.

Here’s a step-by-step breakdown of how a service line warranty works:

  1. Buy the warranty: The process begins with purchasing a service line warranty. Typically, homeowners pay a monthly or annual premium to secure coverage. This coverage remains in effect for a specific period, often renewable annually.
  2. File a claim: When an issue arises with a covered service line, the homeowner initiates the claims process by submitting a claim to the warranty provider. This step alerts the company to the problem and begins the assessment phase.
  3. Wait for the claims assessment: Upon receiving a claim, the warranty provider dispatches a licensed contractor to evaluate the situation. This professional assesses the problem and determines whether it falls under the warranty’s coverage terms.
  4. Schedule a repair or replacement: If the claim is validated, the contractor proceeds with the necessary repairs or replacements. This work is completed according to the terms of the warranty agreement.
  5. Ensure the provider pays the contractor: The final step is for the provider to pay the technician. The warranty company compensates the contractor directly for the covered repairs up to the agreed-upon coverage limit specified in the policy. 

It’s important to note that the specific process may vary depending on the warranty provider and individual policy terms. Prospective buyers should always carefully review the fine print and ensure they fully understand the claims process before purchasing a service line warranty.

Filing a Claim

Here are the steps for filing a claim with your service line warranty provider:

  1. Recognize potential covered issues: Look for signs like discolored water, odd taste in drinking water, pooling water, or soft spots in your yard.
  2. Document the problem: Take photos and write detailed notes about the issue.
  3. Contact your provider: Call, text, or email as soon as possible. Have your policy number ready. Provide details about the problem.
  4. Await a technician’s evaluation: The provider will arrange for a licensed technician to come to your home and assess the issue.
  5. Receive coverage determination: The technician will evaluate the damage and determine if the issue is covered. If covered, approval for repairs or replacement begins.
  6. Repairs or replacement completed: The approved contractor carries out the work.
  7. Payment processed: Your provider pays the contractor directly up to the coverage limit.
  8. Follow-up and confirm satisfaction: Your provider typically checks to ensure the technician has done a good job.

Before damage occurs, keep thorough records of your service line, including maintenance. After the work is complete, keep all documentation related to the claim. Be sure to hold on to receipts for any out-of-pocket expenses.


When you’re in the market for a service line warranty, it’s worth comparing providers. Start by looking at the basics: premiums, covered damages, included utility lines, coverage limits, and exclusions. 

Most well-known home warranty providers, such as Liberty Home Guard and American Home Shield, offer limited coverage for buried service lines.

Several providers focus specifically on covering utility lines. The table below compares premiums and coverage caps for two service line warranty providers: American Water Resources and HomeServe.

ProviderMonthly PremiumCoverage CapsService Call Fee
American Water Resources$5.57–$12.72$4,000–$15,000None
HomeServe$7.57–$20.57$7,000–unlimitedNone

Next, familiarize yourself with the claims process and whether the company offers 24/7 support. 

Also, ask about contractors. Does the company use licensed local professionals? Can you choose your own if you prefer?

Don’t forget to read the fine print. Look for details on waiting periods before claim filing and cancellation policies. 

Reputation also matters. Review consumer ratings and comments on sites like the Better Business Bureau and Trustpilot. Keep in mind that a couple of negative reviews aren’t necessarily a deal-breaker, but a pattern of complaints about specific issues, like frequently rejected claims, is something to watch out for.

Remember, the goal is to find a warranty that gives you peace of mind without breaking the bank. Take your time, ask questions, and choose the one that feels right for your situation.
