If a pipe in your Woodburn home has frozen, shut off water to that line, open the faucet it feeds, and warm the pipe slowly. If a pipe has already burst, shut off the main valve at once, switch off power to any wet area, and call a plumber. Our 24/7 emergency line is (503) 974-3329.
Most winter nights in the mid Willamette Valley sit above freezing, so many people never prepare. The danger comes from the few nights that do not. Pipes in garages, crawl spaces, outside walls and exposed hose bibbs are the ones that freeze first, and a split pipe can pour out gallons an hour once it thaws.
How cold it actually gets here, and what that means for pipes
The National Weather Service's 1991 to 2020 normals for Salem, the nearest station with published data, show average lows of 35.1 degrees F in December, 35.8 in January and 35.9 in February. The lowest daily normal low is 34.6 degrees, in late December. Those are averages, so the real risk sits in the cold snaps around them.
The City of Woodburn's design standards list a frost depth of 12 inches. Buried lines at or below that depth are usually safe. The trouble starts where pipe is shallow, exposed or inside an unheated space. That includes a hose bibb on a north wall, a supply line in a vented crawl space, and a pipe that runs through an uninsulated garage ceiling.
- Garage walls and ceilings, especially above a closed garage door.
- Vented crawl spaces under older homes.
- Hose bibbs and irrigation lines.
- Water lines inside outside-facing kitchen or bath walls.
- Pipes under manufactured homes, behind skirting.
Where pipes freeze first, and what to do about each
| Location | Why it freezes | Fix before winter |
|---|---|---|
| Hose bibb and outdoor faucet | Water sits in the stub and takes the cold directly | Disconnect hoses, shut the indoor valve, drain the line |
| Crawl space supply | Cold air flows through foundation vents | Insulate pipes, close vents in a cold snap if the design allows |
| Garage lines | Often no heat and little insulation | Foam sleeves, seal gaps, keep the door closed |
| Outside-wall plumbing | Wall cavity is colder than the room | Open the cabinet doors on cold nights so room air reaches the pipes |
| Mobile home lines | Exposed under the floor | Heat tape rated for the pipe type and skirting repairs |
A frozen pipe: what to do before it bursts
Water that comes out as a trickle, or not at all, on a freezing morning often means ice in the line. Move fast but carefully.
- 1Open the faucetOpen the tap the pipe feeds. As ice melts, water and steam need somewhere to go, and an open faucet relieves pressure.
- 2Find the frozen sectionFeel along the pipe for a cold, frosted or bulging spot. Most freezes sit along an outside wall or near where the pipe enters the house.
- 3Warm it slowlyUse a hair dryer, a heating pad or warm towels, working from the faucet toward the frozen spot. Never use a torch, a propane heater or any open flame. A flame can set the wall on fire or ruin soldered joints.
- 4Check for leaks as it thawsLook along the pipe for drips or damp spots. A crack may only show once the ice melts.
- 5Stop and call if it will not thawIf you cannot reach the pipe, it is behind a wall, or you see a split, shut off the main valve and call a plumber.
When a burst pipe is an emergency
A pipe that has split spills water at full line pressure. Treat it as an emergency if water is running and you cannot stop it, if it is soaking a ceiling or wall, or if it is near electrical panels, outlets or a water heater.
Know your shutoff before it happens. The City of Woodburn tells homeowners to find their shutoff valve, and its water section can shut water off at the meter if you cannot. If your own line leaks, the city lists its Finance Department at 503-982-5222, option 1, for service-line leaks, though numbers can change.
Our 24/7 line is always open, and we offer same-day appointments when available. Call (503) 974-3329 from a dry spot. We will walk you through what to do until the plumber arrives.
What to do while you wait for the plumber
- Turn off the main water valve and open a low faucet to drain the lines.
- Switch off power to wet rooms at the breaker panel, but only if you can reach it without standing in water.
- Move rugs, electronics and paperwork away from the wet area.
- Photograph the damage and the broken pipe for your insurance claim.
- Put a bucket under drips and mop standing water to limit damage.
- Keep children and pets out of the room and stay out of any area where water touches outlets.
Woodburn local note: the February 2021 ice storm and your shutoff
In February 2021 a snow and ice storm hit the Willamette Valley. Snow fell on Friday, February 12, outages peaked on Saturday the 13th, and an ice storm warning covered the valley on Sunday, with about 1 inch of ice expected in the central valley and warming above freezing forecast for Monday the 15th. Pipes thaw fast when the weather warms, so burst damage often shows up on that warm day.
Oregon's Building Codes Division says emergency repair of concealed freeze-damaged piping over 5 feet needs a plumbing permit. Inside Woodburn, those permits and inspections come through Marion County. Ask your plumber to confirm what your repair needs.
The City says its water crews flush mains each year, mostly in winter, and the flushing can make water look rust colored. That is not a pipe failure. The City advises running cold taps for a few minutes.

Older homes, renters and what the housing mix means
Census survey data shows the median Woodburn home was built in 1978, with about 55 percent built before 1980. Many customer-side water lines in the city's own inventory are galvanized steel, which corrodes inside and can crack more easily when frozen.
About 36 percent of households rent, so if you rent, tell your landlord about a frozen pipe right away and ask who holds the shutoff key. About 7 percent of housing units are mobile homes, where lines under the floor take the cold hardest. If a pipe splits in an old line, ask a plumber about burst pipe repair and whether replacing a failing run makes sense.
Cost and insurance, honestly
We found no verified Woodburn cost figure for burst pipe repair, so we will not quote one. A small accessible repair costs far less than one that needs wall and floor work, and water damage often costs more than the pipe. We give a clear price before work starts.
Whether your homeowner or renter policy covers burst pipe damage varies by policy, so check yours, take photos, and call your insurer promptly. We can write up what we found, but we cannot say what your policy pays.
If you want to know where a hidden leak is, leak detection can locate it without opening walls blindly. We serve Gervais, about 4 miles away, and Mount Angel, about 7 miles away, at all hours.
Questions about this topic
Water freezes at 32 degrees F, but pipes in unheated spaces can freeze when the air stays below that for several hours. Salem's average winter lows run about 35 degrees, so the risk is in cold snaps, not typical nights.
A slow drip on faucets at the end of exposed lines keeps water moving and can relieve pressure. It does not guarantee protection, so insulation and opening cabinet doors help more.
A hair dryer or heating pad on an accessible pipe is fine, with the faucet open. Never use a torch or open flame. If the pipe is in a wall or already cracked, stop and call a plumber.
Oregon requires a permit for emergency repair of concealed freeze-damaged piping over 5 feet. Marion County handles plumbing permits in Woodburn, so ask your plumber to confirm what your repair needs.
The City flushes its mains each year, mostly in winter, which can stir iron and make water look rust colored. The City says that is safe. Run your cold taps a few minutes and call if it does not clear.
