A frozen pipe that has not burst yet is the best possible moment to act. The pipe is still intact, the damage is still zero, and the fix is straightforward.
The problem is that most people do not know they have one until a tap produces nothing. Here is how to recognize it, how to thaw it safely, and what to avoid.
The Puget Sound Problem
Our winters are mild, which is exactly why frozen pipes cause more damage here than in genuinely cold regions.
Homes in Bellevue and across the Eastside frequently have supply lines running through uninsulated crawl spaces, garages, and exterior walls, because deep freezes are rare enough that nobody planned for them. Then a cold snap arrives for three days and finds every one of those runs.
The working threshold is 20°F. Pipes generally begin freezing below that, though uninsulated pipe in an unheated space can freeze higher, and sustained cold matters more than a brief overnight dip. A few hours at 28°F is usually fine. Three days in the teens is not.
Signs a Pipe Is Frozen
No water, or a trickle, from one fixture while others work normally
Frost or condensation on an exposed pipe
Popping, clicking, or hissing from inside a wall
A cold patch on a wall or floor
Bulging on a visible section of pipe
If one fixture has stopped and it is below freezing outside, assume a frozen pipe rather than a supply problem.
How to Thaw It Safely
Open the affected faucet. Melting water needs somewhere to go, and an open tap relieves pressure as the ice releases
Locate the frozen section if you can. Exposed runs in crawl spaces, garages, and under sinks on exterior walls are the usual places
Apply gentle heat, working from the faucet back toward the frozen section. A hair dryer on a low setting, a heat lamp at a distance, or warm towels
Know your pipe material. Copper tolerates more heat than plastic. PEX and CPVC deform and fail under heat that copper handles, so keep the heat low and moving on plastic lines
Watch for water returning. Restored flow means the ice has cleared, and it is worth checking that section for splits afterwards
Never use an open flame. No propane torch, no blowtorch. It is a fire risk; it can damage the pipe, and it is the single most common way a manageable freeze becomes a house fire or a burst.
Be careful with electrical devices near water. If there is standing water or water near outlets, do not plug anything in. CDC guidance on flooded homes is to avoid operating electrical equipment in those conditions and to call an electrician if the panel is past standing water.
If you cannot locate or reach it, call before it thaws. A pipe that has already split will not reveal that until the ice melts and water starts moving.
If It Has Already Burst
Different situation, different response:
Shut off the main water supply immediately
Do not operate electrical switches if water is near outlets or the panel
Contain what you can and photograph everything before cleaning up

Why Pipes Freeze
Uninsulated runs in unheated space. Crawl spaces, garages, attics, and exterior walls. This is the main cause here.
Sustained cold rather than a brief dip. A single freezing night rarely does it. Three days below freezing will.
Still water. Water that is not moving freezes faster than water that is, which is why dripping a tap works.
Drafts. An unsealed gap where plumbing enters the house can drop the temperature around a pipe enough to freeze one that would otherwise be fine.
Prevention
Insulate every pipe in an unheated space. Foam sleeves are inexpensive and take minutes per run
Use UL-listed heat tape on the most exposed runs, and follow the manufacturer's instructions exactly. The listing matters, because non-listed or badly installed heat tape is a known fire cause
Hold indoor temperatures steady, and no lower than 55°F when traveling
Drip the taps served by exposed pipes during a hard freeze. A slow drip is enough, and the Red Cross recommends dripping the cold side from faucets served by exposed pipe rather than every tap in the house
Open cabinet doors under sinks on exterior walls so room heat reaches the pipes. Move cleaners out of children's reach first
Seal drafts where plumbing enters the building
Disconnect hoses and drain outdoor lines before the first freeze

Longer-Term Protection
Replace pipe that keeps failing. Older galvanized and copper supply lines are more vulnerable to freeze damage than modern materials. PEX handles a freeze better than rigid pipe because it can expand somewhat, though it is not freeze-proof and will still split under sustained cold. Insulation matters with any material. Our repiping services page covers replacement.
Book an annual inspection. A whole home plumbing inspection identifies the runs at risk before winter rather than during it.
Install leak sensors near the water heater, under sinks, and in the crawl space. Some models shut off the main automatically, which matters most when a pipe fails while you are away.
Know your main shutoff. Find it, confirm it turns, and make sure everyone in the household knows where it is.
Frequently Asked Questions
How quickly should I act if a pipe freezes?
Immediately. Open the affected faucet, apply gentle heat, and call if you cannot locate or reach it. A frozen pipe that has not burst is far cheaper to deal with than one that has.
Can a frozen pipe burst?
Yes. Water expands as it freezes and the pressure splits the pipe. The split often is not visible until the ice thaws and water starts moving.
What should I never use to thaw a pipe?
An open flame of any kind. No torch, no burner. It is a fire risk, and it can damage the pipe. Also avoid high heat on PEX or CPVC, which deform where copper would not.
At what temperature do pipes freeze?
The working threshold is 20°F, though uninsulated pipe in an unheated space can freeze higher. Sustained cold matters more than a brief overnight dip.
How much does frozen pipe repair cost?
It depends on whether the pipe has split, where it is, and how accessible it is. Thawing an intact pipe is a small job. Our plumber cost guide covers typical local pricing.
Can I prevent frozen pipes completely?
No guarantee, but insulation, sealing drafts, steady indoor temperatures, and dripping taps during a hard freeze reduce the risk substantially.
Call Before It Splits
If a fixture has stopped working and it is below freezing outside, that is the moment to act rather than wait and see.
