Main Water Line Repair in Seattle, WA — Repair the Section, or Replace the Run
Done Right Plumbing repairs and replaces main water lines across Seattle — spot repairs on a single failed section, and full service replacements from the meter to the house. The call usually starts the same way citywide: a meter that will not stop turning, pressure that faded everywhere at once, or a soft green stripe in the parking strip in August.
Real Work in Seattle
In April 2026 we replaced a failed water service at a West Seattle home in the South Delridge blocks — a full run, meter to house. This was a crew job: Ashton, Joseph P., Ben, Steven and Theoren were all on site, and the size of the crew is why the water was back on the same afternoon. The new line went in with fresh connections at both ends and a tracer wire run alongside, so the next person who ever needs to find it can locate it from the surface instead of guessing.
What We Do on a Seattle Water Line
Spot repair on a failed section
When the failure is in one place and the rest of the run is sound, we expose it, cut it out and rebuild that section. When an otherwise healthy line fails for the first time, we treat it as a repair rather than an opening to sell you a replacement.
Full service replacement, meter to house
When the line has failed before, or the material itself is done, we replace the whole run and end the cycle — new polyethylene line, new connections at the meter and the house, tracer wire along the pipe.
Trenchless replacement under what Seattle puts on top
Seattle lots stack a lot over a water service: original concrete walks, brick paths, city street trees in the planting strip. We bore beneath and pull the new line through from two small pits, so what is above the pipe stays where it is. See trenchless water line replacement for the method.
Galvanized service retirement
A lot of pre-war Seattle houses still drink through their original galvanized service. It corrodes from the inside, narrows for decades, and then fails. We replace these on their first serious leak rather than patching metal that is finished.
The water side, specifically
This page is about the pressurized line from the meter to your house. The side sewer — the other pipe Seattle homeowners own — has its own failure modes and its own page: sewer line repair.
What Makes a Seattle Water Line Job Different
From the meter to the house, the line is yours
Seattle Public Utilities owns the water main and the meter. Everything downstream of the meter — including the stretch under your planting strip and front walk — is the homeowner’s, and that is the section that fails, because it is the section installed when the house was built.
The right-of-way has its own rules
When the run crosses the planting strip, utility locates come first and street-use rules apply to any work in the right-of-way. This is a normal part of a Seattle water service job, not a surprise — we plan the locates and the access before the first shovel.
The pipe is often older than the neighborhood’s trees
Ballard, Wallingford, Wedgwood and West Seattle are full of houses whose original galvanized or early copper services went in generations ago. On those houses the material itself is the diagnosis. One pinhole is rarely alone, so an honest quote weighs the cost of patching against the cost of retiring the whole run.
Hills change the math
West Seattle and the city’s ridge neighborhoods put real slope on some runs. Depth, fall and access decide whether a job is a hand-dug afternoon or a bore — which is why we look before we price.
Our Process
1. Prove where the water is going
Meter test with the house shut off, pressure check, and a walk of the run before anyone talks price.
2. Locate everything first
Utility locates on every excavation — water, gas, power and telecom share Seattle’s planting strips.
3. Quote repair and replacement side by side
Both numbers with the reasoning. A sound line with one wound gets a repair quote we stand behind.
4. Do the work with our own crew and gear
The South Delridge job above had five of our technicians on site — that is how a full replacement finishes with the water on by afternoon.
5. Leave it locatable and clean
Tracer wire along the new line, pits backfilled and tamped, surfaces restored.
FAQs About Water Line Repair in Seattle
Who owns the water line between the meter and my Seattle house?
You do. Seattle Public Utilities owns the main in the street and the meter itself; the service line from the meter to your house is private, including where it crosses the planting strip. That is the opposite of what many homeowners assume, and it is why the failed section is almost always on the private side.
Can you replace my water line without digging up the parking strip and front walk?
Usually, yes. We bore beneath walks, planting strips and established landscaping and pull the new line through between two small access pits. Seattle’s narrow lots and original concrete walks are exactly what the method exists for — open-trenching is the fallback for short, shallow, unobstructed runs.
My house still has its original galvanized service — replace it now or wait?
If it is already leaking, replacement is the answer, because patching sixty-plus-year-old galvanized only buys months. If it is not leaking yet, plan for it: budget, pick your season, and do it as a scheduled job instead of an emergency. Galvanized narrows from the inside for decades before it fails, so weak pressure is the early warning.
How long is the water actually off during a replacement?
Usually less than people fear, because most of the day goes into access and pulling the new line while the old one is still live; the shutoff happens for the switchover at the ends. On the South Delridge replacement above, the house had water again the same afternoon. We tell you the expected window before we start.
What does Seattle water line work cost?
The same ranges we publish everywhere: spot repairs on a buried service usually run $2,000 to $6,000, and full meter-to-house replacements $6,000 to $16,000, with length, depth and surface crossings moving the number. The honest version is a locate-first quote — we price what your run actually needs. Full breakdown: water line replacement questions.

Our shop is in Lynnwood, and Seattle is the city we drive into most. North-end neighborhoods are the shortest runs, and we work south through West Seattle, Beacon Hill and Columbia City routinely — the South Delridge replacement above is about as far southwest as the city goes, and it still got a full crew for a same-day turnaround.
