Galvanized and Polybutylene Pipes Don't Age Gracefully

Whole-home re-piping is one of the highest-stakes jobs we perform, and Certified Plumbing & Drain has handled it on residential and commercial properties across the greater Sacramento area for 13 years. If your home still has galvanized steel, polybutylene pipes, or aging copper showing signs of active corrosion, replacement isn't a question of if. It's a question of how much damage you'll tolerate before you call. We've seen the full range: pinhole leaks behind drywall, collapsed galvanized lines with nothing but rust sediment where the bore used to be, and polybutylene fittings that failed without any visible warning. The structural integrity of your plumbing system determines the structural integrity of the home around it. Call (916) 706-7460 and we'll assess the system honestly, not upsell you past what the job actually requires.

Re-piping scope varies considerably by home age, pipe material, accessibility, and how far the deterioration has progressed. A targeted partial re-pipe on a single corroded line is a very different job from a full-system replacement on a 1,960s-era house with original galvanized throughout. We work with copper and PEX as replacement materials, each with distinct performance characteristics, copper for its longevity and rigidity, PEX for its flexibility in tight access runs and its resistance to scale buildup. Access points, wall finishes, the number of fixtures served, and whether the sewer line services connected to the system are also in need of attention all affect the final scope. Every job is different, contact Certified Plumbing & Drain for an accurate estimate.

What Failing Pipes Actually Look Like Failing

The warning signs are specific. Most homeowners see them for months before they act.

01

Discolored Water at the Tap

Orange or brown water running from faucets is iron oxide, rust, breaking loose from the interior of corroded galvanized pipe. It's not a filtration problem. It's the pipe wall telling you it's nearly spent.

02

Reduced Flow Pressure

Galvanized pipe corrodes from the inside out. As mineral deposits accumulate on the interior wall, the effective bore narrows. When multiple fixtures run simultaneously and pressure drops noticeably, the pipe isn't undersized. It's clogged with scale.

03

Recurring Pinhole Leaks

One pinhole leak repaired and done is a repair. Two pinholes in the same line within a year is a system telling you the pipe wall is compromised along its full length. Patching individual spots on corroded galvanized is a temporary measure.

04

Polybutylene Fittings Still In Place

Polybutylene pipe was installed widely from the late 1970s through the mid-1990s. The material degrades on contact with oxidants in municipal water. If the plastic fittings in your system are grey or blue-grey polybutylene, the material is past its reliable service life regardless of whether it's leaked yet.

05

Visible Corrosion at Exposed Lines

Green or white mineral crust at copper joints, flaking at galvanized fittings, and soft spots in visible pipe runs are all indicators of corrosion that extends beyond what you can see. The problem is always larger inside the wall than outside.

06

Unexplained Spikes in Water Bills

If your consumption hasn't changed but your water bill has, you likely have an active leak somewhere in the supply line. Our leak detection process can locate the source before we determine whether repair or full re-pipe is the right scope.

How We Work

The Re-Piping Process, Step by Step

A whole-home re-pipe is a significant undertaking. Here's how Certified Plumbing & Drain approaches it so there are no surprises.

  1. 01

    System Assessment

    We inspect the existing pipe material, trace the supply runs, identify access points, and determine whether a partial or full replacement is warranted. We'll tell you exactly what we find, including if a repair will actually solve it.

  2. 02

    Material Selection and Installation

    We specify copper or PEX based on your system's configuration, access constraints, and long-term performance requirements. New lines are run, connected to existing fixtures, and pressure-tested before any wall surfaces are closed.

  3. 03

    Final Inspection and Restoration

    Water is restored, pressure is verified at every fixture, and we confirm there are no active leaks at any connection point. We document the completed work and walk you through the new system before we leave the property.

Material Selection

Copper vs. PEX: Which Pipe Is Right for Your Home

Homeowners sometimes ask us to simply replace what was there with the same material. That's not always the correct answer, and we won't do it reflexively. Galvanized steel hasn't been the right choice for residential supply lines for decades, we replace it with copper or cross-linked polyethylene (PEX), not more steel. Copper has a multi-decade service life when installed properly and resists bacterial growth in the water column. It's the right choice for most above-slab installations and for homes where the owner wants a material with a long track record. PEX is flexible, which matters in retrofit applications where running rigid pipe through existing framing would require excessive cutting. It also handles freeze-thaw stress better than copper and doesn't accumulate scale on its interior wall the way galvanized does. For homes in Folsom or properties in Citrus Heights with older framing configurations that limit access, PEX often produces a cleaner installation. We'll specify the right material for your home's actual conditions. Not the one that's easier to charge more for. That's a commitment backed by 13 years in the trade and a 5-star average across 20 Google reviews.

What Drives the Cost of a Re-Pipe

  1. 01

    Home Size and Fixture Count

    More square footage and more fixtures mean more linear feet of pipe, more connection points, and more labor hours. A 1,200-square-foot home with two baths is a different job than a 2,800-square-foot property with three and a half.

  2. 02

    Existing Pipe Material and Condition

    Galvanized that has corroded into adjacent framing takes longer to remove cleanly than copper that's been maintained. Polybutylene systems with multiple failed fittings require more careful handling to prevent damage to surrounding drywall during removal.

  3. 03

    Wall and Ceiling Access

    Finished walls require controlled openings and restoration. Unfinished utility spaces, crawl spaces, and attic access routes reduce labor time considerably. We assess access routes during the initial walkthrough so you're not surprised by wall repair costs after the fact.

Re-Piping: Frequently Asked Questions

How do I know if my home has polybutylene pipes?
Polybutylene pipe is typically grey, blue-grey, or black and was installed in residential construction between approximately 1978 and 1995. Check under sinks, at the water heater connection, or at the main shutoff. If the pipe is flexible plastic in those colors, have it assessed. The fittings are often grey plastic or aluminum. The material was subject to a class-action settlement in the 1990s for a reason, the compound reacts with chlorine and other oxidants in municipal water and degrades from the inside.
Can you re-pipe without tearing out all my walls?
In most cases, no, not entirely. We make controlled access openings to run new supply lines and close them cleanly, but whole-home re-piping requires physical access to the pipe runs. The scope of wall work depends on your home's framing, existing access points, and whether we're using PEX (which threads more easily through existing framing) or rigid copper. We walk through access strategy before any work begins so you understand what the restoration scope will look like.
How long does a whole-home re-pipe take?
Most residential re-piping projects on a single-family home complete in one to three days, depending on the home's size, the pipe material being replaced, and access conditions. Your water service will be interrupted during active work periods but restored each evening if the project spans multiple days. We'll give you a realistic timeline during the assessment, not a number designed to get you to sign.
Is galvanized pipe dangerous to leave in place?
It depends on condition. Early-stage galvanized corrosion produces discolored water and reduced pressure but isn't an immediate structural emergency. Advanced corrosion is a different matter: the pipe wall thins, pressure integrity degrades, and a pinhole leak can develop into a full failure without notice. Corroded galvanized pipe also harbors lead-containing scale in homes where lead solder was used at joints. If you're seeing discoloration or pressure loss, don't wait for the failure.
What's the difference between a partial re-pipe and a full re-pipe?
A partial re-pipe addresses a specific deteriorated section or run, a single corroded branch line, for instance, or the supply to an isolated wing of the home. A full re-pipe replaces the entire supply system from the main shutoff through to every fixture. We recommend the scope that's actually warranted by the condition of the system. If a targeted repair will genuinely solve the problem, we'll say so. If the pipe material is uniformly degraded throughout the home, patching one section is a short-term answer to a whole-house problem.
How much does it cost to replace galvanized pipes in a house?
Cost is determined by the home's size, fixture count, pipe condition, access complexity, and the replacement material specified. Every job is different, contact Certified Plumbing & Drain at (916) 706-7460 for an accurate estimate based on your specific system.
