If your home was built in the 1970s or 80s, your pipes may already be on borrowed time. Here's how to know — and what to expect when it's time to act.

Summary:
You’ve probably fixed the same type of leak more than once. Maybe the water pressure in your shower has been slowly fading for a year. Maybe you’ve noticed the water runs a little orange before it clears — and you’ve been telling yourself it’s not that bad.
It might not be. But if your home was built in the 1970s or 1980s and you’re in El Dorado County, Placer County, or Sacramento County, there’s a real chance your plumbing is at or past the end of its designed life. This guide will help you figure out where you actually stand — what the warning signs mean, what a repipe involves, and how to make the call without guessing.
The most common trigger isn’t a dramatic pipe burst — it’s a slow accumulation of smaller problems. Pressure that keeps dropping. A repair that fixed one spot, only for another to spring a leak six months later. Water that runs rust-colored for a minute before it clears up in the morning.
Each of those symptoms on its own might point to an isolated issue. All of them together — especially in a home built before 1985 — usually point to something systemic. The pipes aren’t failing in one spot. They’re failing everywhere, just at different speeds.
The median home in El Dorado County was built around 1982. Galvanized steel pipes — the standard material used in most homes built before 1980 — have a rated lifespan of 40 to 50 years. That math isn’t subtle. If your home is in Placerville, Cameron Park, Shingle Springs, or El Dorado Hills and it was built in that era, you’re likely running on plumbing that has already reached or exceeded the end of its designed service life.
What makes this region particularly unforgiving on pipes is a combination of factors you won’t find in most national guides. Hard water is a real issue throughout El Dorado County and much of the Sacramento foothill corridor. Water traveling through the mineral-rich geology at higher elevations picks up calcium and magnesium deposits that slowly build up inside pipe walls, restricting flow and accelerating corrosion. A copper pipe that might last 70 years in a soft water environment may develop serious problems in 30 to 40 years here.
Then there’s elevation. Placerville sits at roughly 1,900 feet. Pollock Pines is closer to 3,600 feet. At those elevations, winter temperatures regularly drop below freezing, and the freeze-thaw cycle puts mechanical stress on pipes that are already weakened from the inside. It’s not just one thing wearing your pipes down — it’s several things working together, year after year.
In Sacramento proper, the dynamic is a little different but no less significant. The city treats its municipal water with chloramines rather than standard chlorine, and chloramines are more corrosive to copper over time. Older neighborhoods in Land Park, Carmichael, Fair Oaks, and Arden-Arcade — many with homes built in the 1950s through 1970s — are dealing with pipe systems that were never designed to handle decades of chemically treated water.
If your home is in any of these areas and you’ve been patching leaks for a few years, the question probably isn’t whether you’ll need a repipe. It’s whether you want to handle it on your terms or wait for a more urgent situation to force the decision.
This is the question most contractors won’t answer honestly, because the honest answer sometimes means a smaller job. So here it is: if you’ve had one leak in an otherwise healthy system, a targeted repair is almost always the right call. Repiping an entire house when only one section has failed doesn’t make financial sense.
But the math changes when leaks start appearing in different parts of the house, when pressure problems persist after a repair, or when pipe inspection reveals significant corrosion throughout the system. At that point, you’re not fixing a problem — you’re delaying it. Each repair call addresses a symptom while the underlying deterioration continues at its own pace.
Think about it this way: if you’re spending money on pipe repairs every year or two, and each repair only buys a few more months before something else shows up, you’re paying ongoing costs for a system that’s still failing. A whole-house repipe replaces that cycle with a single, permanent solution — new pipes, a clean inspection, and a warranty that actually means something.
There are also situations where the decision gets made for you. Home inspectors flag aging galvanized systems regularly during the sale process. If you’re buying a home in the foothills of El Dorado or Placer County and the inspection report mentions galvanized pipes, that’s not a minor note — it’s a significant finding that affects both the home’s value and your future repair costs. Some buyers negotiate a repipe as a condition of sale. Others factor it into their offer price and handle it after closing.
One more thing worth knowing: some Sacramento-area homes built in the late 1980s through early 2000s contain Kitec piping — an aluminum-core pipe material that’s known to fail prematurely. If you’re not sure what type of pipes you have, a licensed plumber can tell you quickly. That information alone is worth a call.

The biggest reason people put off calling about a repipe is fear of what it looks like. Walls torn apart. Days without water. Living in a construction zone. The reality is considerably less dramatic — but you deserve a straight answer, not a vague reassurance.
A standard whole-house repipe for a single-family home typically takes three to five days. Water is restored each evening, so your family can continue using the home throughout the project. Work is staged in zones, which means at least one bathroom stays functional at all times.
On the first day, our crew protects your floors and furniture, maps out the access points, and begins running new main supply lines — typically through attic or crawlspace access rather than through finished walls wherever possible. By the end of day one, water is back on.
Day two focuses on connecting the new lines to individual fixtures: sinks, showers, the water heater, laundry connections. This is the more detail-oriented work, and it’s where the quality of the crew becomes obvious. A good repipe crew works cleanly, communicates clearly, and leaves the work area organized at the end of each day.
By day three — or later in larger or more complex homes — the system gets pressure-tested before any walls are closed. This step is non-negotiable. If there’s a problem, you want to find it before the drywall goes back up, not six months later. After pressure testing passes, access points are patched, and the final inspection is scheduled.
Speaking of inspections: in California, a plumbing permit is legally required for whole-house repiping. That permit must be pulled by a licensed plumber — specifically one holding a C-36 Plumbing Contractor License from the California Contractors State License Board — and a city inspector must sign off before walls are permanently closed. If a contractor offers to skip the permit to save money, that’s not a savings. It’s a liability that follows the home and can create serious complications if you ever sell or file an insurance claim.
Cost is the question everyone has and almost no one gets a straight answer on. The reason quotes vary so widely isn’t contractor games — it’s that several real factors have a significant impact on the scope of work.
Home size is the most obvious driver. More square footage means more pipe runs, more labor hours, and more access points. Foundation type matters too: homes built on a slab foundation require more labor to access pipe runs than homes with a crawlspace or attic access, and that difference can add meaningfully to the total.
Pipe material is another variable. Both PEX and copper are California code-compliant, and both are good options depending on the home’s water chemistry and the homeowner’s priorities. PEX is flexible, chemically inert, and unaffected by the hard water mineral corrosion that shortens copper pipe lifespan in this region. Copper is more rigid, has a longer track record, and some buyers prefer it for resale perception. The right choice depends on your specific situation — not on which one has a higher margin.
One thing to watch carefully in any quote you receive: drywall repair. Wall patching after a repipe can add significant cost, and it’s frequently excluded from base quotes by contractors who then charge for it separately after the work is done. Before you sign anything, confirm in writing whether wall patching and cleanup are included.
Permits and inspections should also be itemized in any legitimate quote. They’re not optional, and any contractor who presents a price that doesn’t account for them is either planning to skip them or planning to add them later.
We’ve been doing this work in El Dorado, Placer, and Sacramento Counties for over 24 years. We know the foothill housing stock, we know the local water conditions, and we give you a written quote that covers the full scope — materials, labor, permits, and wall patching — before we start anything. The price we quote is the price you pay.
If your home is in the 1970s or 1980s build range — in Placerville, El Dorado Hills, Cameron Park, Folsom, Roseville, Sacramento, or anywhere along the US-50 or I-80 corridor — there’s a reasonable chance your pipes are closer to the end than the beginning. That doesn’t mean you need to act today. But it does mean the conversation is worth having sooner rather than later.
The right contractor will look at your actual situation and tell you honestly whether a targeted repair makes sense or whether a full repipe is the better call. That’s what we do at Murray Plumbing. No pressure, no upsell, no runaround — just a straight answer and a written quote you can actually plan around.
