A repipe replaces the supply lines throughout a house. It sounds enormous and it is genuinely disruptive, but it is a well-understood job with a predictable shape, usually a few days, mostly small holes in drywall, and the water off for less of it than people expect. Here is what the week actually looks like.
| Situation | Repipe? |
|---|---|
| Galvanised steel supply lines | Yes, the material has a finite life and it is ending |
| Third leak in two years | Yes, the pipe is telling you |
| Pinhole leaks appearing in several places | Yes, water chemistry and age |
| Pressure faded across the whole house over years | Usually: the bore has narrowed |
| Brown water at every tap that will not clear | Usually: the pipe is shedding rust |
| One leak, sound copper, clear cause | No, repair it |
| Two reroutes already done | Ask for both numbers before a third |
| Question | Typically |
|---|---|
| How many days? | Two to five for most single-family houses |
| Do I have to move out? | Usually not, most people stay |
| How long is the water off? | Hours at a time, not days, and scheduled |
| Will I have a working bathroom? | Usually, for most of it |
| How many holes? | More than you expect, smaller than you fear |
| Is it noisy? | Yes, during cutting. Not all day, every day |
| When does the mess stop? | When patching finishes, before finish trades start |
The out-of-service question is the one worth raising when it is scoped rather than mid-job. If somebody in the house genuinely cannot manage without water at particular times, say so up front, sequencing around it is easy at the planning stage and awkward afterwards.

| Opened | Not opened |
|---|---|
| Small access holes along each route | The slab |
| Walls at each fixture tie-in | Finished flooring |
| An attic hatch or ceiling access where used | Rooms the routes do not pass through |
| Cabinet backs, occasionally | Anything outside the agreed plan |
A single-storey house with an accessible attic is the easiest version of this job, because most of the run happens overhead and the openings are concentrated at the fixtures. A two-storey house with no attic access above the ground floor is the hardest, and it is worth knowing which you have before comparing quotes.
A repipe is the one time in a house’s life when the walls are open along every supply route. Several small jobs that would each need their own demolition become nearly free at that moment, and they are worth asking about at the quoting stage rather than remembering afterwards.
| Job | Why now |
|---|---|
| Replace a failing pressure regulator | The supply entry is already being worked on |
| Fit or replace an expansion tank | Same access, and a regulated system needs one |
| Replace old fixture shut-off valves | They seize with age, and they are behind the same panels |
| Replace braided supply connectors | Wear items, cheap, and a common cause of indoor water damage |
| Add a shut-off where there is not one | Some older houses have fixtures with no isolation at all |
| Replace an old gate valve on the main | A ball valve turns in seconds at midnight; a seized gate valve does not |
| Insulate hot lines in the attic | The route is open and it will never be this easy again |
None of it is upselling if it is offered as a list with prices and you decline the ones you do not want. What would be upselling is presenting them as necessary. They are not. They are simply cheaper now than they will ever be again, and the main valve row in particular is worth taking.
A contractor who suggests skipping the permit is offering to save you a small amount now in exchange for an unpermitted alteration on your property record. More at plumbing permits in Santa Ana.
We are licensed and insured plumbers, and this site is about leaks — finding the ones you cannot see and repairing them properly. Roughly half of what looks like a plumbing leak turns out not to be one, so the boundary is worth stating plainly.
Roof leaks are a roofer. Water under an air handler is an HVAC technician clearing a condensate drain. Water under an appliance is appliance repair. Drying, restoration and mold are separate trades again, and gas line repair is SoCalGas or a licensed gas fitter. We detect gas leaks, we do not repair gas lines.
The full list, with the trade to call for each, is on what we don’t do.
| What happens | When |
|---|---|
| Pressure test passed | Before anything closes |
| Inspection | Before walls are closed |
| Patching | Ours. We patch what we opened |
| Texture, paint, tile | Finish trades, after us |
| Water pressure | Often noticeably better: a clean bore with no scale |
| Warranty | Two years on workmanship, transferable with the property |
| Paperwork | Permit, inspection, photographs — keep all of it |
The pressure improvement surprises people in older houses. Replacing decades of scale and narrowing with a clean bore changes how the fixtures behave, and it is the part most people mention afterwards. Full terms on guarantees and warranties.
A whole-house repipe typically runs $6,000 to $15,000 depending on size, number of fixtures, storeys and access. The commercial detail, the quoting process and the scheduling are on whole house repipe in Santa Ana.
We will price the repipe alongside the repair so you can compare them properly.
(714) 386-7923Call or text, day or nightSchedule a VisitTwo to five days for most single-family houses, depending on size, storeys and access. A single-storey house with a reachable attic is the fastest version; a two-storey house with no attic access above the ground floor is the slowest.
Usually not — most people stay. The water goes off in blocks of hours rather than days, and you generally keep a working bathroom for most of it. If somebody in the house genuinely cannot manage without water at certain times, say so when it is scoped.
More than you expect and smaller than you fear. Access holes along each route and at every fixture tie-in, sized for the work rather than for convenience. You see the plan and where the openings go before anything is cut.
We patch what we opened. Texture matching, paint and tile are finish trades and are named as exclusions on the quote — stated up front rather than discovered at the end. Booking those in advance is worth doing.
PEX through walls and attic, copper where a run is exposed or matching the existing material is cleaner. PEX bends around corners without fittings, so there are far fewer joints inside walls, and it does not scale in hard water.
Yes, a repipe is code-regulated work. We pull it where it applies and it shows on the quote as its own line. An inspection follows before walls are closed, and the permitted, inspected paperwork is worth keeping for when you sell.
Often noticeably, in an older house. You are replacing decades of scale and internal narrowing with a clean bore, and that is the change most people comment on afterwards.
When you are paying to find out where the next failure will be rather than fixing one. Galvanised steel anywhere in the house, a third leak in two years, or pinholes appearing in several places all point that way.
Typically $6,000 to $15,000 depending on size, fixture count, storeys and access. Two reroutes already done starts to approach it, which is why it is worth asking for both numbers before agreeing to a third.
