2 to 6 Days, Never a Night Without Water | PEX-A & Copper Type L | Permits & Inspection Handled | CSLB #1051553 | Se Habla Español

A repipe is the biggest plumbing decision most homeowners ever make, and it deserves a clear-eyed walkthrough of your actual options. Ser Plumbing repipes SE LA County homes on a clear promise: the job takes two to six days depending on the house, the water is back on every evening, and approved written estimates are honored, with any hidden condition shown to you and approved before it changes anything.

Whether it is a fifty-year-old galvanized choking your pressure, slab-era copper that keeps pinholing, or a remodel that finally justifies doing it right, Luis walks the house with you, explains PEX versus copper without a sales agenda, and quotes both when both make sense.

The problem

The Problem: Why People Call

Six situations bring homeowners to the repipe conversation, and each one changes what the walkthrough looks for.

Low water pressure everywhere, getting worse for years

The signature of galvanized steel closing itself off with internal rust. No fixture is at fault; the arteries are.

Brown or rusty water on first draw

Water that clears after running a minute has been sitting in a corroding pipe overnight. The pipe is flavoring your water.

The second (or third) leak this year

Repeat leaks across different spots are a system statement, not bad luck. At some point the repairs stop buying time and start delaying the decision.

A slab leak forced the conversation

Slab repairs and reroutes fix the leak in front of you. When the line under the concrete keeps failing, the repipe question answers itself. Pipe leak repair →

The remodel is opening the walls anyway

With walls open, repiping costs its minimum. Kitchens, bathrooms, and additions are the lowest-cost repipe opportunity a house ever offers.

Insurance or escrow raised the pipe question

Some carriers and buyers balk at original galvanized or polybutylene. A documented, permitted repipe resolves the question permanently.

Local conditions

Repiping in Paramount & SE LA County

Aging galvanized and copper supply line conditions in Southeast LA County
Two pipe generations dominate our service area

Two pipe generations dominate our service area, and each fails in its own way. Pre-1960s homes in Paramount, Compton, Bell, Lynwood, South Gate, and the older cores of Long Beach and Bellflower typically carry original galvanized steel supply lines. Galvanized does not usually announce itself with floods; it strangles quietly, corroding inward until a half-inch pipe flows like a straw. If your shower dies when the washer fills, you have felt it.

The tract-boom decades poured slabs and embedded copper

The tract-boom decades that followed poured slabs and embedded copper, and that copper is now deep into pinhole season across Lakewood, Norwalk, Downey, and Cerritos. Where galvanized chokes, aging copper perforates, one small leak at a time, each one soaking into concrete or framing before it is found.

Piecemeal repairs left dissimilar metals joined

One more local wrinkle earns attention at the estimate: decades of piecemeal repairs have left many homes with copper spliced directly onto galvanized. Without a dielectric fitting between the dissimilar metals, that joint quietly accelerates corrosion at the connection, which is why we check every transition during the walkthrough and why partial repipes get designed, not improvised.

What's covered

What’s Covered

01

Whole-house repipe (PEX-A or Copper Type L)

Every supply line in the home replaced, wall-to-fixture, with new angle stops and supply connections. PEX-A and Copper Type L are the two materials we stand behind, and we quote both when both fit the house.

02

Galvanized pipe replacement

The definitive fix for rust-choked pre-1960s systems: pressure restored, brown water gone, and the insurance and escrow questions answered for good.

03

Slab-leak repipes

When under-slab copper keeps failing, the replacement system travels through walls and ceiling, and the slab lines are left abandoned in place. The jackhammer stays on the truck. Pipe leak repair →

04

Partial repipes and remodel repipes

Designed sections that make sense on their own: a bathroom group during a remodel, a problem wing, the transition joints that keep failing. Designed, sequenced, and documented so the next phase joins cleanly.

05

Drywall and finish coordination

Repiping opens walls; that is the honest cost of new arteries. Patching is optional: add it to your quote, and we handle the walls start to finish, or leave the finish work to your own painter; your call either way.

06

Permits and inspection

Repipes are permitted and inspected in every city we serve. We pull the permit, schedule the inspection, and build to pass it.

Pricing

Pricing

Repipe pricing depends on the house, and here is the range most homes land in:

Item Typical range
Whole-house repipe, PEX-A Typically, $9,500 to $11,000 for a standard single-family home
Whole-house repipe, Copper Type L Typically, $12,500 to $18,000
Partial / remodel repipes Quoted by scope from the walkthrough
Drywall patching Optional add-on, itemized in your quote when you want it

What moves the number: Home size and fixture count, one story or two, attic and crawl access, material choice, and how much finish work you want handled versus coordinated. The walkthrough settles it, the estimate is free, and the written estimate is honored; if opened walls reveal a condition nobody could see, you see it and approve any change before work continues.

Financing is available for qualifying projects through our booking platform, and standard labor discounts apply.

Why Ser Plumbing

Why Ser Plumbing for Repipes

01

Never a night without water

The job is sequenced so supply is restored every evening. Two to six days of work, zero nights of buckets.

02

Both materials, quoted straight

We install PEX-A and Copper Type L and will quote both when both fit. The choice comes with the tradeoffs explained, and the decision left where it belongs, with you.

03

The owner walks every job

The person who quoted your repipe is the person running it, from walkthrough to final inspection. Questions get answers on the spot, in English or Spanish.

04

Transitions done right

Dielectric fittings at every dissimilar-metal joint, proper supports, protected penetrations. The details that decide whether a repipe lasts fifty years or seeds its own failures.

05

What changes the day it’s done

Steady pressure at every fixture at once. Clear water on first draw. Hot water that holds its temperature. No more listening for drips in the walls, and no more disclosure anxiety when insurance renewal or escrow asks about the plumbing. A repipe is one of the few purchases in home ownership where the before and after are felt the same evening.

06

Designed as a system, not just new pipe

PEX opens a design choice copper never offered: trunk-and-branch layouts that mirror traditional plumbing, or a manifold system with home-run lines giving each fixture its own path and its own shutoff at a central panel. Manifolds put fewer joints inside walls and let you service one fixture without killing water to the house; trunk-and-branch uses less pipe on some floor plans. Which one fits is a house-by-house call we make with you at the walkthrough, and it is the kind of decision that separates a repipe designed for the next fifty years from pipe merely swapped for pipe.

07

Permitted, inspected, documented

A repipe without a permit is a resale problem wearing a discount. Ours close with city sign-off and a paper trail you can hand a buyer or insurer.

08

A repipe, day by day

Day one starts with protection and mapping: floors and furniture covered, access points marked where repair will be simplest, and the first new lines run while the old system keeps serving the house. The middle days move room by room, new lines pressurized and proven as they go, and every evening ends the same way: water on, household functioning. The final pipe day connects fixtures, sets new angle stops, and closes with the full-system pressure test. Then come the city inspection and the drywall scope you chose. Most homes experience the whole thing as a few busy days with a working home every night, which is exactly how it should feel.

Expertise

PEX-A Versus Copper, Without the Agenda

Both materials deserve their reputations. Copper Type L is the traditionalist for a reason: decades of proven service, complete immunity to UV, rodents ignore it, and buyers recognize it in a listing. Its honest weaknesses are cost and the fact that the same water chemistry that pinholed your old copper will eventually work on the new, though Type L’s heavier wall buys decades. PEX-A counters with flexibility that means fewer joints (and joints are where systems fail), immunity to the corrosion that killed your old pipes, quieter operation, better freeze tolerance it will never need here, and a meaningfully lower price. Its honest weaknesses: it cannot run exposed to sunlight, and rodents can chew it, which is why exposed runs and attic routing get planned around both.

Our default guidance runs simple: PEX-A wins most whole-house repipes on value, and copper earns its premium where longevity-minded owners plan to hold the home for decades, where exposed runs demand it, or where resale optics in a particular market justify it. What we will not do is pretend either choice is wrong. The failure mode worth avoiding is not picking the second-best material; it is a rushed install of either one, which is why the transitions, supports, and pressure testing get more of our attention than the brand of pipe.

FAQ

Repiping FAQs

Thirteen straight answers to the questions we hear on the phone every week.

Ask us directly
Ser Plumbing plumber working through a Southeast LA County repipe No agenda We quote both materials when both fit the house
How long does a whole-house repipe take?
Two to six days of pipe work, depending on size and complexity, with water restored every evening, followed by one to six days of drywall repair if you chose to include it. You live at home throughout.
Will repiping fix my low water pressure?

If the cause is corroded galvanized or undersized aging lines, dramatically, and that is the most common reason SE LA County homes repipe. If pressure is low for another reason, the walkthrough finds that instead, and you will not be sold pipe you do not need.

How do I know it’s time to repipe instead of repairing again?

The threshold signs: pressure fading across the whole house, rusty first-draw water, and more than one leak in recent memory. Any two together usually mean the system is done negotiating.

PEX or copper: which should I choose?

The full comparison is above. Short version: PEX-A wins most homes on value, and fewer joints; Copper Type L earns its premium for long-hold owners and exposed runs. We quote both when both fit.

Do you repipe occupied homes?

Almost every repipe we do is an occupied home. Water is back on each evening, work areas are protected and cleaned daily, and the disruption is measured in days, not weeks.

Who fixes the walls afterward?

Your choice, priced your way: patching included in the quote, or itemized so your own drywall or paint contractor takes the handoff. Access cuts are planned for the simplest possible repair either way.
