Repiping replaces a home's interior supply lines entirely, rather than patching leak after leak on pipe that has reached the end of its service life. It is a bigger project than a single repair, but it stops the pattern of recurring failures.
Why Whole-Home Repiping Comes Up In Altadena
Pre-1960 Altadena homes often still run original galvanized supply lines that are now 65 to 100 or more years old, well past their designed service life. Repeated pinhole leaks and pressure loss are common once a galvanized system reaches this age.
Mid-century homes with copper supply lines can also reach a point where multiple leaks in different rooms within a short span signal the whole system is failing, not just one unlucky section.
A home already going through a full remodel or an Eaton Fire rebuild is also a natural point to repipe, since the walls are already open and adding the labor cost of accessing pipe later, after finish work is done, is far more disruptive.
Signs It Is Time To Repipe
Multiple Recent Leaks
More than one leak in different parts of the house within a year or two is a strong repipe signal.
Persistent Rust-Colored Water
Consistent discoloration across multiple fixtures usually means the pipe itself is corroding internally.
Steadily Dropping Pressure
Corrosion narrowing the inside of galvanized pipe reduces flow gradually across the whole house.
Pipe Material Past Its Service Life
Original galvanized supply lines in a pre-1960 home are a common candidate regardless of current symptoms.

Planning A Repipe
We map the home's existing supply line layout first, identifying which walls, ceilings, or crawlspace access points the new lines will need to route through with the least disruption.
Every repipe uses materials meeting California's lead-free NSF/ANSI 372 standard under the AB 1953 framework, whether the home is repiped in copper or PEX.
Material choice between copper and PEX depends on the home's layout, budget, and any seismic considerations, since PEX's flexibility performs well in California's earthquake-prone building code environment.
Material Options
Copper
Long track record and rigid durability, at a higher material cost than PEX.
PEX
Flexible, faster to install in tight spaces, and performs well under seismic movement, now widely code-approved in California.
Partial Vs. Whole-Home
A partial repipe addresses only the worst-affected sections; a whole-home repipe replaces everything at once to avoid repeating the process later.
What Affects The Cost Of Repiping & Whole-Home Pipe Replacement
Scope Of The Problem
A straightforward, isolated repair costs less than a job involving multiple fixtures or a harder-to-diagnose root cause.
Parts & Materials
Fixture quality, pipe material, and whether a part needs to be special-ordered all factor into the final price.
Access & Location
A repair behind a finished wall, under a slab, or in a hard-to-reach crawlspace takes longer than one with open access.
Timing
Standard daytime scheduling costs less than an after-hours or weekend emergency dispatch.
Homeowner's insurance often covers sudden, accidental damage like a burst pipe, but typically does not cover gradual wear, an aging part failing on its own, or deferred maintenance. Check your specific policy for what it actually covers before assuming either way.
These factors explain why prices vary. For your exact number, call (626) 898-6169 and describe what you're seeing, we'll give you a flat price before any work begins.
Common Questions
How long does a whole-home repipe take?
Most residential repipes take two to five days depending on the home's size and how accessible the existing walls and crawlspace are.
Is PEX as durable as copper?
PEX has a strong track record and performs well in seismic conditions, though copper remains a proven, long-lasting option. The right choice depends on the home's specific layout and budget.
Do I need to move out during a repipe?
Most homeowners stay in the home during a repipe, though water will be shut off in sections at a time as work progresses through the house.
Will repiping require cutting into my walls?
Some drywall access is typically needed to route new lines, which we patch as part of the job, though the amount varies based on the home's layout and existing access points.
Before We Arrive
- Note the location and approximate date of any past leaks or repairs, since a pattern across multiple rooms is useful evidence for planning the repipe.
- If you know your home's approximate construction year, have that on hand. It helps confirm whether the existing pipe is galvanized, copper, or another material.
- Think through which areas of the home you would want prioritized first if the work needs to happen in phases.
