Is Replacing a Sewer Line Covered by Homeowners Insurance?
Only if sudden damage, like a burst pipe, causes it. Normal wear or aging pipes are not covered.

What your policy looks at is the cause, not the fact that the sewer line failed. A pipe that cracks from age or tree roots slowly growing in is wear and tear, and no homeowners policy covers that. A pipe that bursts suddenly, say from a hard freeze, is different and the resulting damage is typically covered. Some insurers sell a separate endorsement called service line coverage, built for exactly this gap. Ask about it when you bind the policy, since adding it later costs more than including it at closing.
Worth checking before you bind
Sewer lines fail from age more often than from sudden breaks, and that's the part a standard policy skips. Comparing quotes now lets you see which ones include service line coverage without raising the price much.
What does service line coverage actually pay for
Service line coverage, when it is added, pays to repair or replace the buried pipe itself, not just the damage that leaks out of it. A standard policy might cover the water damage inside the house from a sudden backup, but it still won't touch the pipe in the yard that caused it. The endorsement closes that specific gap. It covers the sewer, water, or power lines running from the house to the street, along with the cost of digging up the yard to get to them.
Excavation cost is the part buyers tend to underestimate. Locating a broken line, cutting through a driveway or a finished yard, then repairing the surface afterward can cost more than the pipe itself. Most service line endorsements include this, but the amount they'll pay is capped. Asking what that limit is matters more than assuming it covers the whole job.
Older houses carry more of this risk. Clay and cast iron pipes, common in homes built before the 1970s, crack and shift with age in ways copper or PVC generally don't. If the inspection report or seller disclosure mentions the age or material of the sewer line, that's worth bringing to the person writing the policy, since it affects whether the endorsement is worth adding now rather than later.
The deductible on a service line endorsement is often separate from the one on the rest of the policy. It can work differently than the main deductible, so it's worth asking how it's set rather than assuming it matches the rest of the policy. That detail, along with the coverage limit and whether tree root damage is included, is worth confirming at binding rather than after something fails.
How does this fit into closing and escrow
The binder the lender wants before closing just needs to list dwelling coverage and any required endorsements, not every optional one. Service line coverage can usually be added after closing if there isn't time to sort it out before the deadline. Adding it later typically means a new underwriting step and a slightly higher cost than if it had been part of the original policy, but it won't hold up getting the keys.
Lenders care about dwelling coverage because that's what rebuilds the house if it's destroyed. They generally don't require service line coverage, since it protects pipes and wires, not the structure itself. That means it's a decision for the buyer to make, not something the lender will flag on the closing documents, so nobody is going to bring it up unless the buyer asks.
Escrow accounts pay the homeowners premium each year along with property taxes, and that payment is based on whatever is on the policy at renewal. If service line coverage gets added mid-year outside of escrow, it may need to be paid separately or folded in at the next renewal. Asking the person writing the policy how the timing works avoids a surprise bill later.
None of this needs to be settled before the closing date arrives. What matters at closing is that the dwelling coverage amount matches what the lender asked for and that the binder is in hand. The sewer line question can be answered in the weeks after, once there's less pressure and more time to look at what the inspection said about the pipe's age and material.
One thing worth asking before you sign
Ask whether service line coverage is included or priced as an add-on, and what its deductible and limit are. If the inspection mentioned the sewer line's age or material, mention that too.
