Freeze-related bursts
Water expands as it freezes and splits the pipe wall, but the split often leaks only after thaw. Exposed lines in crawl spaces, garages and exterior walls are the usual victims. See also frozen pipe water damage.

Burst Pipe Water Damage: what it covers
Quick answer
When a supply pipe bursts, close the main valve, switch off power to wet areas if you can do so safely, and call. Portland Water Damage Restoration answers 24/7 for Portland and Multnomah County. A crew is dispatched as fast as one is available, extracts the water and dries walls, floors and ceilings to measured readings.
A split pipe is the most violent small thing that happens in a house. A line the width of a thumb can release gallons a minute, and if it fails inside a wall or above a ceiling, much of that water is out of sight. By the time a stain appears, floors and insulation below may already be soaked. The speed of the response matters more here than in almost any other kind of water damage.
Portland's mild winters hide a risk. Freezes are infrequent, so pipes in crawl spaces, garages and exterior walls are seldom insulated to the standard of colder cities. During the January 2024 ice storm, Portland firefighters received more than 1,000 potential water-emergency calls over roughly five days, mostly burst pipes, and the calls peaked as pipes thawed. The damage often shows up when the ice melts, not when it forms.
Freezing is only one cause. Old galvanized lines corrode from the inside, copper develops pinholes, solder joints and fittings fail, and high household pressure strains older runs. Whatever the cause, the restoration work is the same: stop the water, take out what is standing, find where it went, and dry. A plumber then repairs the pipe, and the technician tells you early if one needs to come first.

Where is the main shutoff and how do I use it?
The main valve is usually where the water line enters the house: a basement wall, a crawl space, a garage or an outside meter box. Turn it fully clockwise. If it will not move, leave it and call. Then open a low faucet to drain what is left in the pipes.
In many older Portland houses the valve is a round-handled gate type that corrodes and sticks, and a modern quarter-turn ball valve may have been added by a past owner. Find yours now, tag it, and try it once when nothing is wrong.
If you cannot reach the interior shutoff, the meter box at the street has a city valve, but it usually takes a special key and the city may need to be called.
Why do pipes burst when they thaw?
A freeze splits the wall of the pipe, but ice plugs the opening until it melts. The water flows only when the temperature rises, so the flood often starts hours after the cold has passed, while you are asleep or away. The split can be a thin crack that releases a lot of water under pressure.
Reports from the January 2024 storm describe calls peaking on the thaw, not the freeze. That timing catches households out. The pipe looked fine during the cold snap, so nobody checked it, and the failure showed up on the first mild afternoon.
If you suspect a frozen line after a hard night, open the nearest faucet slightly, keep the heat on, and find the shutoff before the temperature rises.
How far can the water travel from a burst pipe?
Farther than the stain shows. Water follows framing, wiring holes and plumbing chases, so a pipe split in an upstairs wall can soak the ceiling, the wall cavity and the floor below. A technician maps the whole path with a camera and meter rather than drying only the visible patch.
Think of water as always looking for the lowest route. Inside a two-story house it will drip through a ceiling into a room, run down inside a wall to the basement, and spread along joists under hardwood. A crew that dries only the stained patch can leave the real wet area behind and a mold problem for later.
Take a photograph of every stain, however small, and note any sound of dripping. It helps the technician check the right places first.
What should you document for an insurance claim?
Photographs and short videos of the water and each damaged room, the time you noticed it, the time you closed the main, the plumber's invoice and the restoration moisture log. Keep damaged items until the insurer says otherwise. Whether the claim is paid is your insurer's decision under your policy.
Claims often stall because the record is thin. Take wide shots of each room, then close shots of stains, swollen trim and wet insulation. Note the brand and age of the failed pipe or fitting if you can see it, and ask the plumber to write down the cause.
Save receipts for anything you buy to limit the damage, such as tarps, fans or a night in a hotel, and ask your insurer about what it expects before you spend.
How do you find a leak you cannot see?
Check the water meter with every fixture off: if it moves, a line is leaking. Then look for warm or damp spots on floors, listen near walls and ceilings, and call. A thermal camera and meters trace hidden water without opening walls, which is why technicians use them before cutting.
Slab leaks, in-wall leaks and leaks above ceilings can run for days before a stain appears. A technician reads the moisture pattern and picks the smallest opening that gives access.
A plumber then pressure-tests or inspects the line to find the failure itself. The two trades work on different halves of the same problem.
Warning signs
Signs you need burst pipe water damage
Do not touch a ceiling that is bulging with water, because it can drop without warning, and keep out of any room where water is near a light fixture or outlet. Shut the main, then phone (833) 490-5225.
- The sound of water running when nothing is turned on
- A ceiling that sags, bulges or drips from a seam below a bathroom or attic run
- A warm, damp patch on a floor over a slab, which can point to a leak in a hot line
- A sudden drop in water pressure at several fixtures
- Stained or bubbling paint low on an exterior wall after a cold night
- A spike in the water bill with no change in use
- Water dripping from a basement ceiling directly under a bathroom or kitchen
- Frost on an exposed pipe in a crawl space, followed by silence or a hiss when the temperature rises
Our process
How our burst pipe water damage visit works
Close the main and make it safe
The first step, which you can do before anyone arrives, is shutting off the main. The technician then checks for water near outlets, light fixtures and the panel before entering.
Find where the water went
A thermal camera and moisture meter follow the water down through the wall, floor or ceiling, often showing it has gone much farther than the visible stain.
Extract and open the wet cavities
Standing water is removed. Ceiling drywall holding water is cut so it cannot collapse, and wall insulation and the lower section of drywall are removed where they are saturated.
Dry the structure
Air movers and dehumidifiers run, with air directed into opened cavities. In a multi-story house, drying often covers more than one floor.
Hand over for the pipe repair
A plumber replaces the failed section. The technician coordinates timing so the repair and the drying do not get in each other's way.
Options
Types and options for burst pipe water damage
Corrosion and age failures
Older galvanized and some copper lines wear from inside. They may weep for months and then rupture without warning. Houses from the early and mid twentieth century often have at least some original plumbing.
Joint, fitting and pressure failures
A compression fitting, a stop valve under a sink or a supply hose can let go at any time of year. These tend to be smaller releases, but a long unattended leak can soak a cabinet or floor.
Job stories

- What homeowners notice
- On the first mild afternoon after several freezing days, a homeowner hears running water and finds the kitchen floor wet and a ceiling stain spreading in the room below.
- What we do
- With the main closed, the technician extracts water, traces the path with a meter and thermal camera, removes wet insulation and the lower drywall in the wall cavity, and sets dehumidifiers and air movers on both floors.
- What to expect
- Readings reach the dry target after several visits, a plumber repairs the pipe, and rebuilding of the wall is quoted separately.
Cost
How much does burst pipe water damage cost in Portland?
The bill depends on how long the pipe ran, how many floors the water reached and what finishes sit in its path. We print no dollar figure, because none we could source describes a Portland job.
| Job | Typical range | What it includes |
|---|---|---|
| Duration of the leak | Reported by you, confirmed by readings | A leak that ran for hours reaches farther than one caught in minutes |
| Floors and rooms involved | Measured on site | Water in a ceiling cavity often soaks the room below it as well |
| Materials to remove | Quoted on site | Insulation, drywall and flooring are removed only where readings call for it |
Your price is confirmed on site, and put in writing, before work begins.

Multnomah County
Why burst pipe water damage is different in Portland metro
The January 2024 freeze is Portland's most recent reminder of how little prepared a mild climate can be. The storm lasted nearly five days, with four of those days never rising above freezing, and about 633,000 people in Multnomah County lost power, according to a regional magazine. Heat went out in houses with pipes in exterior walls, and thawing followed.
Pipe materials vary by the age of the house, and we have no sourced Portland data on which era used what. Older homes often have a mix of original lines and later repairs, and the repair is where problems tend to appear.
Many Portland-area homes have plumbing in crawl spaces and unheated basements. Insulating exposed lines and knowing where the shutoff is are the two cheapest ways to reduce the damage from a failure.

What the January 2024 Freeze Taught Portland About Burst Pipes

FAQ
Burst Pipe Water Damage FAQs
Can I stay in the house after a pipe bursts?
Often yes if the rest of the house has water and power. Water on a single floor can be managed with the rest of the home in use. If the heating or water supply is off, plan on staying elsewhere until it is restored.
Does the plumber or the restoration crew come first?
The shutoff comes first, which you can do yourself. A plumber then repairs the pipe, and the restoration crew extracts and dries. The two can overlap, and the technician helps sequence them.
How long will drying take?
Often three to five days for a single wet room, longer if water reached walls on multiple floors. Readings decide, not the calendar.
Will wet insulation have to be replaced?
Usually yes when it has soaked through, since wet insulation loses its value and stays damp. Dry insulation near but outside the wet area can often stay.
Is a burst pipe covered by insurance?
Sudden pipe failures are more often covered than seepage or flood, but only your insurer can say, and it depends on your policy. Keep photographs, the plumber's invoice and the moisture log.
