What actually happens inside a pipe when it freezes?
Trapped water pressure, not the ice itself, is what usually splits a frozen pipe.
Most people who get a call to research why do pipes burst in cold weather imagine that the ice cracked the pipe right where it formed. The truth is, when the ice plug forms, the water between that plug and your closed faucet has nowhere to go. That means there's increased pressure on that section of pipe until it reaches its bursting point. That point is often a few feet from the ice, sometimes inside a wall.
That's also why the damage shows up late. Then the afternoon warms up, the ice melts, and water pours out. Eastside cold snaps tend to break fast, with a few nights in the teens and then rain. As a result, the call usually comes on the thaw day, not the coldest night.
Watch for these signs that a line has frozen:
A faucet that gives a trickle or nothing while others run fine
Frost on an exposed pipe in the crawlspace or garage
A toilet that won't refill after a flush
Which pipes in a Redmond home freeze first?
The pipes that freeze first are the ones closest to outside air. That means hose bibs, crawlspace runs, and lines in exterior walls, roughly in that order.
Where the pipe runs | Why it freezes | What we usually find |
Hose bibs on north- or east-facing walls | Little sun, and an attached hose traps water | A split just inside the wall |
Crawlspace supply lines | Foundation vents pull in outside air | Cracked fittings near a vent |
Kitchen sinks on an exterior wall | Closed cabinets block the house's heat | Cracked supply lines under the sink |
Garage walls | Unheated, with the door often open | Breaks on laundry or water heater lines |
Terrain plays a part too. Homes on Novelty Hill, Union Hill, and around Bear Creek sit higher and more exposed than houses along the Sammamish River. In our experience, they're often the first calls when a freeze settles in. Still, low ground isn't safe ground. On clear, still nights, cold air drains into the Sammamish Valley toward Woodinville.
The City of Redmond's winter weather guidance tells residents to wrap indoor and outdoor pipes once temperatures fall below freezing. A few other habits help too:
Disconnect hoses and cover hose bibs before the first frost
Cover crawlspace vents during a hard freeze, then uncover them once it warms
Open sink cabinets on exterior walls on cold nights
Keep the heat at 55°F or higher when you travel
How does frozen pipe repair work before the line splits?
Frozen pipe repair begins by locating the ice plug and then slowly thawing it from the faucet end towards the direction of the frozen area, allowing melted water to escape.
If the frozen section is exposed and safe to reach, you can start yourself:
Open the faucet the line feeds, both hot and cold.
Warm the pipe with a hair dryer, starting near the faucet.
Work toward the cold section until full pressure comes back.
Never use a torch or open flame, and avoid using a hair dryer near standing water.
However, if the frozen section is behind drywall, call us.
A plumber can use an infrared thermometer to locate the frozen pipe without having to cut openings in the wall.
Once water flows again, watch that line for an hour or two. A pipe can look fine, then start dripping as the last ice melts out of a hairline crack.
What does burst pipe repair look like for each pipe type?
Burst pipe repair depends mostly on what the pipe is made of. Copper and PEX usually need a short section replaced, while older plastic and steel often need more.
Pipe material | How it fails in a freeze | Typical repair |
Copper | Splits lengthwise | Cut out the split and add a new section |
PEX | Pipe often survives, but fittings crack | Replace the failed fitting and check the rest |
CPVC | Turns brittle and cracks | Replace the section and inspect nearby joints |
Polybutylene (gray plastic) | Fittings and pipe both give out | Stop the leak, then plan a replacement |
Galvanized steel | Rusted threads fail under stress | Patch the break, then talk about a repipe |
Plenty of Eastside homes have a mix of these, because past owners fixed one leak at a time. So when a house keeps breaking in the same places, patching becomes the expensive option. If you're facing a third repair in two winters, a whole-house repipe is worth pricing.
What should an after hours plumber handle on the first visit?
An after hours plumber's first job is to stop the water, make the house safe, and get your supply back on. The permanent fix can sometimes wait for daylight.
On a night call, that usually means:
Isolating the broken section so the rest of the house has water
Repairing or capping the break, depending on access
Checking for a second split, since a freeze rarely stops at one spot
Pointing out wet areas that need drying before mold starts
Plenty of people searching how fast can an emergency plumber arrive want a single number. Honestly, it depends on what everyone else's pipes are doing that night. During a regional freeze, active flooding gets seen before a frozen line that isn't leaking yet. Our 24/7 emergency plumbing service lists the urgent calls we take.
Whoever comes out, it's fair to ask about their certification. Washington's Department of Labor & Industries says only L&I-certified plumbers can legally do plumbing work on someone else's property.

Frequently asked questions
1. What should you do in the first ten minutes of a burst pipe?
Close the main water valve, then cut power to any room where water has reached outlets or cords. Next, open the lowest faucet in the house so the lines drain and the leak slows sooner. Turn off the water heater's breaker, or set a gas unit to pilot. Then take photos, call us, and move rugs and electronics out of the water's path.
2. Where is the main water shutoff in most Redmond homes?
The main shutoff is where the water enters the house, in older ramblers or split-levels that is in the crawlspace along the front foundation wall, in newer homes it may be a garage wall or utility closet. If it's truly elusive there is a valve on the meter box near the street, but that is city property so it should be a last resort.
3. Why do crawlspace pipes burst during a cold snap?
Cold snaps cause crawlspace pipes to burst because they are vented to the outdoors, after two or three nights below freezing the air in the space will mimic outside temperatures. Pipes along foundation vents and the rim joist are especially at risk, while insulation slides down along studs and is frayed by rodents, exposing bare spots on the pipe.
4. What does the plumber need to know when you call?
Call us, and tell us, if water is still running, or coming from somewhere unusual, or if it has reached an electrical device. Tell us your address, and any security code, or the location of your main water valve. The type of pipe, is helpful, like copper or gray plastic, it determines, what kind of repair parts, we bring.
5. Can a slow leak wait, or is it an emergency?
We can usually wait, on a slow leak, from a small break, or a bucket, under a drippy p-trap, but it is an emergency, if the drip, accelerates, or the damp spot, is spreading. Sagging ceilings, qualify as an emergency, if drywall, is saturated, it can collapse, without warning. You can often stave, off an emergency, by closing the nearest, valve to the leak, which might not be far from a fixture.
6. How much does burst pipe repair cost in Redmond?
Charges are based on how much work is needed to reach the broken pipe, not the size of the break itself. A small crack that we can see in a crawlspace or garage is much less expensive than the same type of break behind a finished wall. We will always give you an estimate for repairs, it will never be surprises when we bill you.
7. Does homeowners insurance cover a burst pipe?
Homeowners insurance typically covers the cost of water damage due to a burst pipe, but rarely the repair of the pipe itself. Freezing damage can also be denied if the home was unheated, so you should contact the insurance company and have the plumber describe the situation, and keep the broken piece of pipe if the plumber has to remove it.
8. Will a frozen pipe always burst once it thaws?
Many frozen pipes thaw without incident, especially PEX, which tends to 'stretch' as it freezes, but copper and rigid plastic are less forgiving. A pipe that has frozen more than once in the same winter is more likely, if it has been weakened by freezing. Thaw it out slowly, with a faucet left open, and watch for drips for the next couple of hours.
