Repiping in Woodburn, OR means replacing the water supply pipes inside your home, either the whole house or the worst runs. It is the permanent answer when old pipe keeps leaking, water comes out brown, or pressure drops. Our licensed plumbers can look at your pipes and explain which parts need replacing.
Woodburn is an older housing market. The median home was built in 1978 and about 55 percent of units predate 1980 (ACS 2020-2024, via Census Reporter). Those decades often used galvanized steel for supply lines, so many homes here are at or past the age where the pipe wears out.
Signs it is time to repipe
One leak does not mean the whole system is bad. A pattern does.
- Pinhole leaks keep appearing in different spots, especially after one repair.
- Water from the hot tap runs brown or orange, then clears.
- Pressure is weak at several fixtures even though the main valve is open.
- Visible rust, flaking or crusty green buildup on exposed pipes.
- Brittle plastic lines, such as old CPVC, that crack when touched or bumped.
- Your insurer or home inspector flagged polybutylene or galvanized pipe.
If you have a leak now, shut off the main valve first. For an active leak, see burst pipe repair.
Galvanized, copper and PEX compared
Three materials matter for a Woodburn home. Here is how they differ.
| Material | Strengths | Drawbacks | Typical use |
|---|---|---|---|
| Galvanized steel | Strong when new. | Corrodes from inside, narrows and loses pressure. Rusts at threads. | Common in homes from the 1960s and 1970s. Replace rather than extend. |
| Copper | Long life, heat tolerant and widely accepted. | Costs more, requires soldering or press fittings, and can pit in some water. | Exposed runs and many remodels. |
| PEX | Flexible, so fewer fittings and easier routing through walls and attics. Tolerates cold better than rigid pipe. | Must be protected from sunlight. Not allowed in every location. | Whole-house repipes. |
Bob Vila reports national material costs of about $0.40 to $2 per foot for PEX and $2 to $8 per foot for copper. Labor is the larger share of the job.
Whole-house repipe or partial repipe
A whole-house repipe replaces nearly every supply line and fixture stop in one project, often through the attic, crawlspace or small wall openings. It makes sense when galvanized pipe has failed in several places, or when you plan a remodel anyway. We can often replace hot lines first if the cold side is still sound.
A partial repipe replaces one failing section, such as the run to a bathroom or the lines under a slab. It costs less and keeps the disruption small, but old pipe left in place can fail next. We will tell you which pipes look worn and which look serviceable, and you decide.
For homes with slab leaks, a new route through the attic or walls can avoid cutting concrete. See leak detection if you are not sure where the water is escaping.
Water service line replacement
The service line runs from the City meter to your house, and its condition affects everything inside. The City of Woodburn's lead service line inventory from October 2024 counted 7,709 lines and found no lead. It also notes that many customer-side lines are galvanized steel, which is the sourced reason older Woodburn lines fail from rust.
Replacing the private-side line means trenching or boring from the meter to the house. HomeServe contractor data puts Oregon averages near $185 for diagnosis, $964 for repair and $3,359 for replacement. National averages are $222, $1,039 and $3,581. Your price depends on length, depth and surface.
If you are unsure whether your line is galvanized, ask us to check. The City also asks owners of homes built in 1986 or earlier to call its lead and copper survey line.
How a repipe project runs
- 1Inspection and planWe check the pipe material, the shutoff, the pressure and where each run goes. You get a written scope and a clear price before work starts.
- 2PermitAltering piping inside walls, ceilings and floors needs a plumbing permit in Oregon. Marion County issues plumbing permits and inspections in Woodburn.
- 3Shutoff and protectionWater is off during the work. We lay down protection and plan so you have at least one working bathroom when possible.
- 4New lines installedWe run PEX or copper, set new fixture stops and strap the pipe properly. Old pipe is capped or removed.
- 5Pressure test and inspectionThe system is tested before walls close. A county inspector looks at the work.
- 6Patch and restorationDrywall holes are small. Patching and paint are usually separate trades, so we tell you in advance.
Mobile and manufactured homes
About 7.3 percent of Woodburn housing units are mobile homes (ACS 2020-2024). Their supply lines often run under the floor, where PEX is a common replacement. Skirting and insulation protect those lines in winter, and a leak there can go unseen for a long time.
If you own or manage one, ask us to check the crossover and the shutoff on the same visit. Plans for added fixtures can be priced under plumbing installation while the floor is open.
What shapes the cost of a repipe
Angi publishes a national range of about $1,500 to $15,000 for a whole-house repipe, with an average near $7,500. These are national ranges, not Woodburn quotes and not our prices. What moves your number:
- Size of the house and number of bathrooms and fixtures.
- Material choice: PEX or copper.
- Access: open attic and crawlspace versus finished plaster or tile.
- Whether you replace the service line and the shutoff at the same time.
- Permit and inspection fees through Marion County, and any drywall repair.
Call (503) 974-3329 and we will look at the pipes and give a clear price before work starts. Insurance rarely pays for repiping that is wear and tear, but it may cover damage if a pipe suddenly bursts, so check your policy.
Repiping questions, answered
Look at exposed pipe near the water heater or in the crawlspace. Galvanized is dull gray, threaded at the joints and attracts a magnet. Copper is orange-brown and PEX is flexible plastic, often red, blue or white.
Often yes. Hot lines wear faster, so some homeowners replace those first. We check the cold side and tell you whether it is worth doing both at once.
It depends on the size of the house and access. Many smaller homes take a few days, and larger or hard-to-reach homes take longer. We give a timeline with the written scope.
For one isolated leak, repair. For repeated leaks on old pipe, replacing is usually the better use of money, since another failure tends to follow. Copper leaks that are small can often be sleeved or cut out and repaired.
Often yes. If a slab line leaks, we can abandon it and run new lines overhead through the attic, which avoids cutting the slab. It needs access and a plan we go over with you.
Yes. We serve Mount Angel and Silverton from our Woodburn address. Call for a visit and we will tell you which local office handles the permit.
