Cost guide
How much does sewer line replacement cost in Edmonds?
Sewer Line Replacement cost in Edmonds, WA: what sets the price, and who owns the sewer under the street (unpublished — we confirm it). Free estimates.
The short answer
The price of replacing a side sewer comes down to how long and deep the line is, which method fits it (trenchless or open trench), what sits on top of it, and whether your city makes the section under the street yours. A camera inspection and a free estimate turn those variables into a written number for your property.
Your number
Your price comes from your line — not a chart
We'd rather give you a real number than a range that doesn't fit your property. The estimate is free: we look at what your job actually needs and put every viable option in writing with its price.
- Pipe bursting — New pipe pulled through the old path from two access pits
- Open-trench replacement — Excavate, replace and restore along the line
- Replacement under the street — Right-of-way work where your city makes it yours
What's different in Edmonds
Who pays for the pipe under the street
Edmonds doesn't publish who owns the section under the street, so we confirm it for your address before quoting any work there — it can change the scope a lot.
In Edmonds the private drain pipe on your property is yours to keep in repair, and the city owns and maintains the sewer mains. The city's published guidance doesn't say who owns the stretch under the street, so we confirm it for your address rather than guess.
Parts of Edmonds are served by Olympic View Water & Sewer District instead of the city — the name on your sewer bill tells you which.

What sets the price
The cost of sewer line replacement comes down to these.
Length and depth of the line
A longer or deeper side sewer means more pipe, more excavation at the access points and more labor. Depth also decides how much shoring and safety work a trench needs.
Method: trenchless or open trench
Pipe bursting replaces the line through its existing path from access pits; open trench digs the whole run. Which one fits depends on the pipe's condition, alignment and what is around it — not on preference.
What's on top of it
Lawn costs far less to restore than a driveway, mature landscaping, a retaining wall or stairs. Trenchless methods often avoid most of that restoration.
Under-the-street work
In Seattle you own the side sewer all the way to the public main, so a break under the street — and restoring the street — is part of your project. Some neighboring cities maintain that section themselves.
Permits and inspections
Side sewer work needs a permit from your city or sewer district, and right-of-way work can need more than one. Fees vary by scope and change over time.
Shared or unusual lines
Some older Seattle blocks share one side sewer between houses, and older lines can run under foundations or neighbors' yards. Locating the line first avoids surprises.

Sewer Line Replacement cost: questions people ask
Why can't you give me a price over the phone?
Because the variables that set the price — length, depth, pipe condition, what's on top of the line and whether the street section is yours — are only known after the line has been located and seen on camera. A phone number would be a guess; the estimate is free.
Does trenchless replacement always cost less than digging?
Not always. It often costs less once restoration is counted, because a driveway or landscaping stays put, but it only fits some lines. We show you both when both are viable.
Does homeowners insurance pay for a new sewer line?
Usually not for the pipe itself. Standard policies treat it as maintenance; a separate service line endorsement can cover it. Check your own policy.
