Burst Pipe
Burst Pipe Water Damage: what it covers
Quick answer
A burst pipe in a Seattle house means shutting off the main, then extracting water and drying walls, floors and ceilings before mold starts. Seattle Water Damage Restoration answers phones 24/7 and schedules same day when a technician is free. A licensed plumber repairs the pipe; the crew dries and cleans everything the water reached.
A pipe that lets go inside a wall can run for hours before anyone notices. In a house with plaster over lath, the water soaks the lath, runs down inside the cavity and appears at a baseboard or ceiling two rooms from the break. By then the damage is wider than the stain.
Seattle's older housing stock is the reason this call is common. About half of the city's homes were built before 1960, and plumbers describe pre-1960 houses as often keeping their original galvanized steel supply lines. Those pipes corrode from the inside, narrowing and flaking until a section or a fitting fails, sometimes with no warning at all. Soft local water, which plumbers describe as corrosive to galvanized steel, is cited as a contributor, though we cannot put a number on it.
The job has two halves that go to two different trades. A plumber repairs or replaces the failed line, and a restoration crew extracts the water and dries the structure. Doing them in the right order, with the water off first, keeps the damage from growing while you wait for either.
Do not touch a wet outlet, cord or appliance, and do not turn power back on until the area has been checked. Call (833) 490-5225 and, if it is safe, close the main valve.

Our process
How our burst pipe water damage visit works
Shut off the water
Close the main valve, then open a low faucet to drain the line. If the valve is stuck, the technician helps you find another shutoff, such as the meter valve at the street, and tells you what to do while you wait for a plumber.
Find the path of the water
Water follows framing, pipes and gaps. Meters and a thermal camera trace it through the wall, across the floor and into the ceiling below, so no wet cavity is missed behind plaster or paneling.
Extract and remove the sodden materials
Standing water is extracted, saturated carpet pad and insulation are removed, and wall or ceiling sections are opened where a meter shows trapped water. Plaster and lath that can dry in place are left alone.
Dry the structure
Air movers and dehumidifiers run until the readings match an unaffected area. Winter damp slows this, so expect several days and a return visit for readings.
Coordinate the pipe repair
A plumber repairs the failed section and checks the rest of the line. Ask about replacing a run of corroded galvanized pipe, since the next failure is usually nearby.
Cost
How much does burst pipe water damage cost in Seattle?
A burst pipe job is priced on the wet area, the number of rooms and the drying days, with the plumber's repair billed separately. We found no Seattle pricing, so the figures below are national.

What homeowners notice
A homeowner finds a brown stain low on a hallway wall and a water meter that moves with every tap closed. A section of original galvanized supply pipe has split behind the plaster.
What we do
With the main closed, the technician traces the wet path with a meter and thermal camera, removes only the soaked plaster section and insulation, and sets dehumidifiers and air movers. A plumber repairs the line separately.
What to expect
The wall cavity reaches its dry reading after several visits, and rebuilding of the wall is quoted separately once drying is signed off.

What do you do in the first minutes after a pipe bursts?
Close the main shut-off, switch off power to wet rooms only if the panel is dry and easy to reach, and open a low faucet to relieve pressure. Photograph the damage, lift valuables, and call a plumber and a restoration crew. Do not use electrical items near the water.
Locating the main valve is the one piece of preparation worth doing on a dry day. In a Seattle house it is often where the supply enters the basement or crawl space, behind the water heater or at a hose bib on an exterior wall, and a stiff old valve may break if forced.
If the valve will not turn, stop trying to wrench it. Shut the meter valve at the street with a key if you have one, or call. Both a plumber and a restoration crew can help find the shut-off.
Why do old Seattle houses have so many hidden pipe leaks?
Pre-1960 houses often retain galvanized supply lines that corrode inside, and plaster-and-lath walls hide a slow leak for months. A cast-iron stack or clay lateral adds drain risk. The result is damage that appears far from the actual pipe.
Galvanized pipe was a standard supply material until copper took over, and many Craftsman and mid-century houses still have it, partly or entirely. These sources are plumbing-company descriptions, so treat them as a general pattern rather than a rule.
Plaster over lath is slow to show a wet wall. Paint may hold for weeks while the lath behind it stays damp, and when the stain finally appears, the damage can span several feet. That is why moisture meters, not eyes, decide how much opens.
Does homeowners insurance cover a burst pipe?
Sudden pipe failures are commonly covered, while gradual leaks and long-term corrosion are often excluded. Whether yours qualifies depends on the policy wording and the adjuster's findings. Report early, keep photographs and the moisture log, and keep the failed section if you can.
Insurers tend to distinguish between a sudden and accidental discharge, which is typically covered, and ongoing seepage, which is typically not. The plumber's description of what failed matters, so ask for a written note.
Coverage is your insurer's decision. A restoration crew can supply photographs, readings and an itemized scope, but cannot promise what a claim will pay.
Options
Types and options for burst pipe water damage
Pinhole and corrosion failures
Galvanized pipe rusts from the inside out, and a small hole can spray a fine mist into a wall for weeks. The moisture shows up as stains and mold before it ever makes a puddle. These are the most common failures in older Seattle houses.
Fitting and joint failures
Compression fittings, soldered joints and old supply connectors loosen with age and vibration. These tend to leak a measurable amount and may be easier to spot, often under a sink or at a water heater.
Burst from pressure or cold
Excess pressure or a freeze splits a pipe lengthwise. Hard freezes are the exception here rather than the rule, so exposed pipes in crawl spaces and exterior walls are rarely protected. See frozen pipe water damage.
King County
Why burst pipe water damage is different in King County
The oldest plumbing tends to sit in the oldest streets, where Craftsman bungalows, foursquares and early apartment buildings have been remodeled again and again, layering new copper onto old galvanized and cast iron. The joint between old and new metal is a favorite place for leaks.
Crawl spaces under older houses hold the supply lines in the cold, wet dark. A line that drips into a vented crawl space may go unseen for a season, soaking the insulation above and raising humidity that feeds mold. See crawl space water damage.

FAQ
Burst Pipe Water Damage FAQs
How do I know the leak is inside a wall?
A meter that moves with every fixture off is the clearest sign. Stains, soft plaster, warm spots and the sound of running water point the same way. A technician with a moisture meter and a thermal camera can trace the wet area without cutting anything.
Should I replace all my galvanized pipes?
A plumber should advise on that. A single failure often means the rest of the line is similarly worn, and a replacement is less disruptive before a second leak than after. We handle the water damage; the re-pipe decision belongs to you and a plumber.
Can the walls dry without removal?
Sometimes. Intact plaster, solid wood and plywood often dry in place. Wet insulation and saturated drywall do not, because they hold water against the framing. The technician reads the walls first and explains each opening.
What if I am not home when it happens?
The damage grows with every hour, so the main valve is the best protection. If you travel, some people close it before leaving. A leak that ran while the house was empty is more extensive, and the insurer will ask how long it ran.
How long does drying take after a burst pipe?
A single room typically needs three to five days of equipment, and multiple rooms or a ceiling and wall cavity can run longer. Winter air is damp, so drying is slower than in a dry climate. Readings, not the calendar, decide when it ends.
Who pays for the plumber and the drying?
Each is billed separately, by the plumber and by the restoration company. Insurance, if it applies, may cover both under a sudden-discharge claim. Ask for written estimates from each so you can send them to your insurer.
