Repipe · Corona, CA
When the third pinhole in a year shows up, you are not fixing leaks anymore; you are subsidizing a pipe that has decided it is finished. A repipe ends that cycle in a few days, with a written schedule and a house you can still live in.

The tipping point
A repipe replaces the pressurized water supply piping inside your house, the hot and cold distribution running through walls, ceilings, and attic to every fixture. It does not touch your drains, and it usually does not touch the service line from the meter, though the two jobs are often planned together.
Almost nobody sets out to repipe a house. What happens instead is a slow accumulation: a pinhole behind the laundry, then a weeping joint above the hall ceiling, then a drip that shows up as a stain in the guest bedroom. Each one is a modest repair. Together, over eighteen months, they cost more than the permanent fix and come with the added tax of not knowing where the next one will surface, possibly over hardwood, possibly while you are on vacation.
The signals that a system has crossed from repairable to finished are fairly consistent. Multiple leaks in different parts of the house within a couple of years, rather than one recurring problem area. Rust-colored or metallic-tasting water on first draw in the morning. Hot side pressure noticeably weaker than cold, because hot water accelerates the corrosion that narrows the pipe. Visible green or white crust on exposed copper at the water heater or under sinks. Volume that collapses when a second fixture opens. And the plainest one of all: a plumber has already told you the pipe is at end of life, and you have been hoping to get another year out of it.
Our job on the estimate visit is to tell you honestly which side of that line your house is on. Sometimes the answer is that you have one bad branch and a repipe would be overkill. We will say that.
Material
PEX is cross-linked polyethylene, run as flexible tubing from a manifold or in home-run branches to each fixture. Its advantages are practical: far fewer joints, so far fewer failure points; it can be routed through existing cavities with dramatically less drywall opened; it will not corrode from Corona’s hard water or pit from aggressive soil chemistry; it tolerates a freeze better than rigid pipe; and it is quieter, because it does not transmit water hammer through the framing the way copper does.
Copper is the material most Corona homes were built with, and a properly installed copper repipe with modern fittings is an excellent, extremely long-lived system. It is rigid and mechanically tough, it is unaffected by UV where a run has to be exposed, and some homeowners simply prefer metal in the walls. It costs more in both material and labor, and it requires more wall opened because it cannot be snaked around corners.
What we will not do is tell you one is universally correct. What we will do is price both against your actual house, single story versus two story, accessible attic versus none, slab versus raised foundation, because those factors change the gap between the two numbers more than the material list price does.
One thing worth knowing: if your existing copper failed early from pinholes, that same water is still going to be in the new pipe. That is a good moment to talk about a softener or filtration, not as an add-on sale but because it protects what you are about to spend.
What we are replacing
Corona built in distinct waves, and each wave has its own characteristic failure. Knowing which one you are in tells us most of what we need before we arrive.
01
Pre-1960 construction near downtown and the Circle City historic district. Rusts inward until the bore is a fraction of original, then fails at threads. Brown first-draw water and a shower that dies when someone flushes are the classic tells.
02
Gray plastic with crimp or acetal fittings, roughly late seventies through mid nineties. The fittings and the pipe both degrade with chlorinated water. There is no partial fix worth paying for; the system gets replaced.
03
The most common repipe we do here. Thin-wall copper in eighties and nineties tracts developing pinhole leaks from the inside, often accelerated by hard water, high velocity in undersized runs, and stray current.
04
Decades of partial repairs leaving copper spliced to galvanized to CPVC with whatever fitting was on the truck. Every dissimilar-metal junction is a galvanic cell quietly eating itself.
05
A house plumbed for one bathroom now running three plus a laundry and irrigation. The pipe is not leaking, it is simply too small, and no amount of pressure adjustment fixes volume.
06
Homes where a slab leak has already been rerouted once. When the under-slab lines are the same age and material as the one that failed, an overhead repipe retires the whole risk at once.
Sequence
The honest version, including the parts nobody enjoys.
Every fixture counted, every accessible run traced, attic and crawl access checked, and the wall openings marked. You get a written scope that names the rooms and the number of access cuts before you commit.
Permitting handled with the City of Corona. On day one, floors are covered, furniture is moved clear of work walls, and containment goes up where drywall will be opened.
The new lines are run and joined while the existing system stays live as long as possible. This is why a repipe is not a week without water.
A single planned shutoff moves the house onto the new pipe. The system is pressure tested, the water heater and all fixtures are reconnected, and lines are flushed and disinfected.
The inspector sees open walls before anything is closed. That is the entire point of pulling the permit, and it is the record that protects you at resale.
Access holes are patched, taped, and textured to match. Paint is typically the homeowner’s or a painter’s, and we will tell you plainly which finish work is in our scope and which is not.

Why here
Manufacturers quote pipe life under laboratory conditions. Corona is not laboratory conditions, and three local factors compress those numbers meaningfully.
Hardness. The city’s blend of Temescal basin groundwater and imported State Water Project supply commonly runs in the fifteen to twenty grain range. Scale builds on every heated surface and on the inside of every hot line, narrowing the bore. A narrower pipe means higher water velocity for the same demand, and high velocity is what erodes the protective oxide layer inside copper, which is the first step toward a pinhole.
Pressure. Corona spans a large elevation range, and homes sitting low in a pressure zone can see static pressure well above the range residential fittings are designed for. High static pressure stresses every joint continuously and makes thermal expansion events sharper. A repipe on a house with no working pressure regulator is a new system installed under the same conditions that killed the old one, which is why we check static pressure at the estimate, not at the end.
Thermal cycling. Attic runs in Corona see extreme summer temperatures. Hot lines in an unconditioned attic expand and contract through a much wider range than the same pipe in a coastal climate, and that movement works joints loose over decades. Proper support, sleeving where pipe passes through framing, and expansion allowance are not optional details here.
Layer those on top of the age clusters, galvanized downtown and in Circle City, polybutylene in the late-eighties tracts, thin-wall copper across the nineties expansion through El Cerrito, Corona Hills, and Chase Ranch, and the pattern of whole neighborhoods repiping within a few years of each other makes complete sense.
Straight answers
| Factor | Why it changes the number |
|---|---|
| Fixture count | The real unit of measure is not square footage, it is fixtures. Three bathrooms, a kitchen, a laundry, a wet bar, and four hose bibs is a bigger job than a large house with two baths. |
| Stories | A second story means running lines through finished ceilings and interior walls. Single-story homes with attic access are the most efficient repipes we do. |
| Access | A walkable attic or a raised foundation crawlspace cuts labor substantially. No attic access, a tile roof over shallow trusses, or dense insulation adds hours and access cuts. |
| Material choice | PEX or copper. The delta varies with the house, which is why we quote both against your actual layout rather than a per-foot rule of thumb. |
| Wall finish | Standard drywall patches and textures cleanly. Plaster, wallpaper, tile surrounds, or specialty texture raise restoration cost and are called out separately in the estimate. |
| Slab versus raised | On slab-on-grade homes, lines that ran under the concrete get rerouted overhead. That is more pipe and more ceiling work than a raised foundation repipe, and it also permanently ends slab leak risk. |
| What gets added | Shutoffs at every fixture, a new pressure regulator, an expansion tank, a recirculation loop, or a softener loop. Each is optional, each is priced separately, and none appears without your say. |
| Permit and inspection | Included in scope and stated in the estimate. Skipping it is not something we will do. |
We do not quote a repipe over the phone. A walkthrough is the only way to count fixtures, check access, and give you a number that survives contact with the house.

Repipe FAQs
Yes, in almost every case. The new system is installed alongside the old one while the existing pipe stays live, so the water is only off for the planned cutover and short test windows.
You will have dust, plastic sheeting, and crew in the house during working hours, and one or more rooms will be inaccessible for a day. Water is on every evening. Families with infants, medical needs, or a strong aversion to construction sometimes choose to stay elsewhere for the cutover day, and that is a reasonable call, not a necessary one.
More than you would like and fewer than you fear. PEX needs an access point at each fixture group, at direction changes, and where lines drop out of the attic, typically small, rectangular, patchable openings rather than open trenches.
Copper needs more, because rigid pipe cannot be routed around obstructions. This is the single biggest practical difference between the two materials, and it is why we mark the openings during the walkthrough so the number is on paper before you decide.
Patching, taping, and texture matching are in our standard scope, and the estimate says so explicitly. What is normally not included is paint, because matching an aged wall color credibly is a painter’s job and pretending otherwise leaves you with a patchy room.
If you want paint handled as part of the project, say so at the estimate and it can be scoped in. What we will not do is leave you with bare patches and no conversation about it.
Modern potable PEX is rated for drinking water and, after the system is flushed, most homeowners notice nothing. A very small number of people detect a faint plastic note in the first week or two, which fades as the pipe is used.
Worth noting: if your current complaint is metallic or rusty-tasting water from corroding galvanized, a repipe in either material will be a dramatic improvement. And if the taste concern is about Corona’s water itself rather than the pipe, that is a filtration question.
Frequently, yes, and sometimes spectacularly. If the cause was corroded galvanized or scaled hot lines, new correctly sized pipe restores volume you may not have had in twenty years.
If the cause is a failed pressure regulator, a partially closed main valve, or a restricted service line outside the house, a repipe alone will not fix it. That is exactly why we measure static and flowing pressure at the estimate, so we do not sell you a repipe for a problem it will not solve.
Yes, and yes. A whole-home repipe is permitted work in the City of Corona, and the inspection happens while the walls are still open.
It matters most later. An unpermitted repipe is an undisclosed material alteration to the house, and it surfaces during a resale inspection at the worst possible moment. The permit is a small line item that protects a large asset.
On a slab-on-grade home, a repipe reroutes those lines overhead through the attic and walls rather than replacing anything under the concrete. Nothing is left pressurized beneath the floor.
That has a real secondary benefit: it permanently retires your slab leak exposure. For homeowners in Corona who have already had one slab leak, that alone is often the deciding argument for repiping rather than repairing again.
A properly installed PEX or copper system in a house with controlled pressure and reasonable water chemistry should be a multi-decade solution, realistically the last repipe most owners will do.
The qualifiers matter, though. Uncontrolled high static pressure and very hard water are what shortened the life of the pipe you are replacing. Fixing the regulator and considering a softener are how you make the new system reach its potential rather than repeating the old one’s history.
Yes, and sometimes that is genuinely the right answer. If the failures are all in one addition, one branch, or one section of a mixed-metal system, a partial repipe of that section is a legitimate and much cheaper fix.
We will tell you when that is the case. What we will not do is sell a partial repipe on a system where the trace shows the same material and age throughout, because you will be calling about the next section within a year.
Estimates are usually available within a day or two, and dispatch answers around the clock if you are currently dealing with an active leak. Scheduled repipe starts depend on permit turnaround and crew availability, typically within one to two weeks.
If you have water coming through a ceiling right now, that is an emergency call, not a repipe call. We stabilize the leak first, then talk about the permanent plan once nothing is actively getting wet.
