Whole-Home Repiping in Oregon
There is a point where patching a supply system stops being maintenance and starts being a hobby. Usually the third leak in eighteen months is when the arithmetic becomes obvious.
PEX or copper, permitted and inspected, drywall repair included in the quote.
When repiping is the right decision
Individual leak repairs are cheap and repiping is not, so the case for the big job has to be real. It usually rests on one of four things.
Repeat failures. Two or three leaks in different places within a couple of years is the system telling you it has reached the end, not a run of bad luck. The next failures are already forming; you simply have not found them. This is the most common reason people call us.
Material. Galvanized steel and polybutylene both fail systemically. Galvanized corrodes internally from the day it is installed, and by sixty or seventy years there is nothing left to save. Polybutylene, common in construction from the late 1970s to the mid 1990s, becomes brittle and fails without warning, particularly at fittings. In both cases the whole system shares the same age and the same fate.
Water quality and flow. Rusty or discoloured water at first draw, water that runs brown after the supply has been off, and pressure that drops noticeably when a second fixture opens are all symptoms of internal corrosion narrowing the bore. In an old galvanized system the pipe can be down to a fraction of its original diameter.
Timing. If the house is being remodelled, or the walls are open for other work, repiping during that window costs a great deal less than doing it later, because the expensive part of a repipe is access, not pipe.
What is in your walls now
Galvanized steel, pre-1960s Oregon housing, which is most of inner Portland, Salem, Albany, Corvallis and the older valley towns. Threaded steel pipe with a zinc coating that stops protecting it after a couple of decades. Restricted flow, discoloured water, pinhole leaks. Not repairable in any meaningful sense once it starts.
Polybutylene, late 1970s to mid 1990s, often grey or blue plastic with crimped or plastic fittings. Chlorinated water degrades it from the inside. Sudden failures, frequently at fittings inside walls. Where we identify it, we recommend replacement whether or not it has leaked yet.
Copper, the long-lived standard, but not immortal. Copper that has run at high static pressure, or in aggressive water, develops pinholes; once one appears, more usually follow along the same runs. Erosion at bends from turbulent flow is a common local pattern in high-pressure areas.
CPVC and early PEX, generally fine, though certain fitting generations have known issues. Worth identifying rather than assuming.
Third leak in two years? Worth pricing the whole job.

Both are correct answers and we install both. The choice is about the building, the budget and your preferences, not about one being right.
PEX is flexible cross-linked polyethylene. Because it bends, it can be run through existing framing with far fewer openings in the wall, which is the single biggest cost driver in an occupied-house repipe. It does not corrode, it tolerates freezing better than rigid pipe, it can expand somewhat before splitting, which matters east of the Cascades, and it is quieter, with no water hammer transmitted through rigid runs. It is also faster to install, which shows up in the labour line.
Run as a home-run manifold system, each fixture gets its own line from a central manifold, so an individual fixture can be isolated without shutting the house down, and pressure stays stable when two fixtures open at once. It is the configuration we would recommend in most repipes.
PEX limitations: it must not be exposed to sunlight, some types are unsuitable for particular applications such as direct connection at a water heater without a transition, and rodents can damage it in an unprotected crawl space, solvable with sleeving where that risk exists.
Copper is rigid, long-proven, unaffected by UV, and it is what many owners simply prefer to have in the walls. It costs more in both material and labour, and it needs more wall access because it cannot be snaked through framing. In a house where the walls are already open, that penalty largely disappears and copper becomes very competitive.
Our default recommendation for an occupied Oregon home is PEX home-run; for an open-wall remodel where the owner wants copper, copper. We will price both if you want the comparison.
How a repipe actually runs
It starts with a walkthrough, not a phone estimate. We need to see the fixture count, the existing routing, the crawl space or basement, the attic where relevant, the panel and manifold options, and how the walls are constructed, plaster and lath behaves very differently from drywall and changes the access plan entirely.
You get a written, itemised quote: material, fixture count, access points, drywall restoration standard, permit, and the schedule.
On the day, we protect floors and furnishings, open the access points we identified, and run the new system alongside the old one wherever possible, which is what keeps the water on. Then the changeover: each fixture group is switched to the new lines, the old pipe is abandoned in place or removed where it is accessible, and the system is pressure tested.
The inspection happens before anything is closed up. Then drywall patching, texture matching, and paint to the standard in the quote.
A typical three-bathroom Oregon house is three to five days for the plumbing and a few more for the finishing. Larger or plaster-walled houses take longer.
We walk the house and quote in writing, no per-fixture guessing.
Book a WalkthroughLiving in the house while it happens
Almost every repipe we do is in an occupied house, and the water is off for hours rather than days, typically one working day during the changeover, and often only part of it, because we phase the switchover by fixture group.
What to expect: crews in the house during working hours, cutting and drilling noise, dust in the areas being opened even with sheeting up, and furniture moved away from the affected walls. Bathrooms come back into service progressively rather than all at once.
What we do about it: agree the phasing before we start so you know which bathroom is working on which day, sheet and protect everything in the work areas, clean up daily rather than at the end of the job, and give you a working fixture overnight in every case.
Households with a newborn, someone working from home on calls, or accessibility needs should say so at the walkthrough. The phasing can usually be arranged around it if we know in advance.
Drywall, access and restoration
The pipe is a small part of a repipe. Access is most of it, and how a contractor handles the walls is where quotes diverge most.
We plan access points deliberately: at fixture groups, at direction changes, and at the manifold, using crawl spaces and attics wherever they can carry the runs so the wall openings stay few and small. PEX flexibility is what makes that possible.
Our quotes include drywall restoration, patched, taped, textured to match and painted to the edge of the affected area. What we cannot promise is an invisible match on an aged painted wall, and we would rather say that now than argue about it later; a full wall repaint is the only way to guarantee no visible edge, and some owners choose it.
Plaster and lath is its own conversation. It is more fragile, patches are more visible, and the labour is higher. On older Portland and Salem housing we cover this specifically at the walkthrough.
When comparing quotes, check whether restoration is included at all. A repipe quote that ends at the pipe is not comparable to one that ends at paint.
What drives the cost
Fixture count and the number of bathrooms first, that sets the amount of pipe and the number of terminations. Then the number of storeys, since running between floors is harder than running across one. Then wall construction: drywall over stud is straightforward, plaster and lath is not. Then material choice, PEX or copper. Then how much of the routing can go through accessible crawl space and attic rather than through finished walls.
Slab construction adds cost, because runs that would have gone under the floor have to be rerouted overhead. Houses with no crawl space and no attic access are the most expensive per fixture for exactly that reason.
Permits and inspection are included, as is restoration. The quote is fixed after the walkthrough, and the only thing that changes it is something genuinely concealed, asbestos-containing material, an unexpected structural condition, which we would stop and discuss rather than absorb or invoice quietly.
Galvanized or polybutylene? Replacement is the recommendation.

Whole-home repiping, answered
Three to five days of plumbing for a typical three-bathroom house, plus a few days for drywall and paint. Plaster-walled or multi-storey houses take longer. Water is off for hours, not days, usually part of one day during the changeover.
Almost never. We phase the changeover so there is a working bathroom overnight throughout, and agree the sequence with you before starting.
PEX for most occupied-house repipes: fewer wall openings, better freeze tolerance, quieter, and less expensive. Copper where the walls are already open or where you simply prefer it. Both are code-compliant and long-lived; we will price both.
In our quotes, yes, patched, textured and painted to the edge of the work area. We cannot promise an invisible match against aged paint, and we say so up front. Always check whether a competing quote includes restoration at all.
Only if they need it. Supply and drainage fail for different reasons and on different timescales. If the house has cast iron drains showing scale or perforation, doing both while the walls are open saves a great deal, we will assess the drains during the walkthrough and tell you honestly.
It removes a known deduction. Galvanized or polybutylene supply is something buyers and inspectors flag, and a documented, permitted repipe with a warranty answers it. Keep the paperwork, unpermitted work has the opposite effect.
Most homes stay occupied throughout. Ask how we phase it.
