Repiping & Whole-Home Pipe Replacement in Auburn, WA
When a home's original galvanized or aging copper pipe is the real problem, patching one leak at a time stops making financial sense. We replace the whole system once, done right.
More Than One Leak Is a Pattern, Not Bad Luck
If a home has needed two or more pipe repairs in the past year, or shows steadily dropping water pressure with no single identifiable cause, the underlying supply pipe itself, not any one fitting, is usually the real problem. This is especially common in Auburn homes built before the 1990s still running original galvanized supply lines, which corrode from the inside and eventually need full replacement rather than another isolated patch.
Repeat Pipe Leaks
A second or third leak in unrelated locations within a year points to system-wide pipe failure.
Rusty or Discolored Water
Internal corrosion in galvanized pipe shedding into the water supply.
The Water Service Line: A Separate Question
The service line runs from the meter into the house, and callers ask about it often. A meter that runs with everything off, a wet strip of lawn or a sudden pressure drop all point to it. Our page on water service line repair and replacement covers signs, digging versus trenchless methods, ownership and pricing in full.
If the pipe inside your home is also old steel or failing, the whole system may deserve a look. That is where repiping comes in.
Two Honest Options
PEX is faster to install, more flexible around existing framing, and typically costs less; copper lasts longer and is the more traditional choice for homeowners planning to stay put for decades. Neither is objectively wrong, and we'll walk through the real trade-off for your home's layout and your own plans rather than pushing whichever material we happen to have on the truck. Where a slab leak is the trigger for the conversation, we'll also confirm whether a full repipe or a targeted repair actually makes more sense first.
Days, Not Weeks, in Most Homes
A single-story home typically takes 2 to 3 days for a full repipe, including patching the access points opened during the work; a larger or multi-story home can take longer depending on layout. Water is off for portions of each day but restored each evening, and we coordinate the schedule with you upfront rather than leaving a home without water overnight.
Partial vs. Whole-Home Repipe
Not every repiping job means replacing every pipe in the house. If corrosion or failures are concentrated in one section, a bathroom group or a specific supply run, a partial repipe addressing just that section can be the more honest and less disruptive answer than a full whole-home job. We assess the actual condition and failure pattern throughout the house before recommending the scope, rather than defaulting to the larger, more expensive job.
Typical Whole-Home Repipe Pricing
Small single-bath homes sit at the low end. Larger, two-story or slab homes cost more. Covers PEX or copper supply, shutoffs and a pressure test. Drywall patching is quoted separately.
The right number depends on the number of fixtures, the pipe path and how much of the wall must open. You see the price before any pipe is cut.
Choosing the Size of the Fix
Copper that leaks at a single soldered joint can often be repaired. Pinholes along the length are a sign of wear from the inside, and that points toward a repipe. CPVC supply pipe from certain eras can turn brittle and crack, so owners sometimes replace it before it fails.
Some owners ask to replace the main line now and the interior pipes later. That works when the interior pipe is sound. If it is the same age and material as the failed section, doing both together spares you a second round of disruption.
Permits and Inspection
A whole-home repipe typically requires a permit and a final inspection, since it's significant enough work that most jurisdictions want it verified before walls are closed back up. We handle scheduling that inspection as part of the project timeline, not as an extra step left for the homeowner to coordinate separately.
Replumbing Through the Attic Instead of the Floor
When the old pipe sits under a slab, new supply lines can run overhead through the attic. This avoids cutting concrete and is common in single-story homes. It does open ceilings or walls at drops to each fixture, so patching drywall belongs in the plan.
Which Auburn Homes Come Up for Repiping
Repipe conversations in Auburn tend to start with the older homes near Downtown Auburn, where the supply material is the question. Public listing data puts West Hill and Lea Hill homes in a newer range, so we confirm the pipe before assuming anything. In Lakeland Hills and other later subdivisions, the issue is usually one problem section rather than the whole house, which is why we scope the system before recommending a full repipe.
Common Questions
It requires some access to walls and ceilings, but modern techniques minimize the number of openings needed compared to older repiping methods. We walk through exactly what access is required before starting.
It depends on your budget, how long you plan to stay in the home, and your home's layout. We'll give you a straight comparison rather than a default answer.
If the cause is internal corrosion narrowing the pipe diameter, yes. If it's a pressure regulator or a different issue, repiping won't help, which is why we diagnose the actual cause before recommending a full repipe.
Not always. Galvanized pipe corrodes from the inside, so low pressure and rusty water are the usual signs it is wearing out. If leaks keep showing up, replacing the whole system usually makes more sense than repairing one run at a time.
In many single-story homes, yes. Overhead routing avoids cutting the slab. Access to the attic and the layout of walls decide how well it works, and we check both before recommending it.
Most whole-home repipes fall between $5,000 and $15,000. Smaller single-bath homes sit at the low end, and larger or two-story homes cost more. The price covers the new supply pipe, shutoffs and a pressure test, and you see it before any pipe is cut.
