Frozen Pipes: What to Do Right Now and How to Prevent Them

A frozen pipe is one of the few plumbing emergencies where quick, calm action makes all the difference. When water freezes it expands, and that pressure can split a pipe and flood a home the moment it thaws. If you turn on a faucet during a cold snap and only a trickle comes out, you may have a frozen pipe. Here is exactly what to do, what to avoid, and how to keep it from happening again.

How to Tell a Pipe Is Frozen

The signs are usually clear once you know them.

• No water or only a trickle from a faucet during freezing weather.
• Frost or bulging visible on an exposed pipe.
• Cold spots along a pipe run in an unheated area like a basement, crawl space, garage, or exterior wall.
• Gurgling or clanking sounds when you run water.

The pipes most at risk are those in unheated spaces and along outside walls, plus outdoor hose bibs and sprinkler lines.

What to Do Right Now

Move quickly but carefully.

1. Open the faucet served by the frozen pipe, both hot and cold sides. Running water, even a trickle, helps melt the ice and relieves pressure as it thaws.
2. Locate your main shutoff valve now, before anything bursts, so you can stop a flood instantly if the pipe has already cracked.
3. Apply gentle heat to the frozen section. Use a hair dryer, a heating pad, warm towels, or a space heater kept a safe distance away. Start near the faucet and work back toward the cold spot.
4. Keep applying heat until full water pressure returns. Thawing can take time, so be patient.

Never use an open flame, a blowtorch, or a propane heater to thaw a pipe. Direct flame can burst the pipe, damage the wall, and start a fire, and it is a leading cause of house fires during cold snaps. Do not leave any heating device unattended.

When to Call a Licensed Plumber Immediately

Some situations are beyond DIY and demand a professional right away. Call a licensed plumber when:

• You cannot locate the frozen section or cannot safely reach it, for example inside a finished wall or ceiling.
• A pipe has already burst or is leaking. Shut off the main water supply immediately, then call for emergency service.
• The pipe will not thaw despite your efforts, or you are dealing with multiple frozen lines.
• Water has reached electrical outlets, the panel, or wiring. Water and electricity together are a serious shock hazard, so keep clear and shut off power to the affected area at the breaker if you can do so safely.

Preventing Frozen Pipes Next Time

A few habits go a long way. Insulate pipes in unheated areas with foam sleeves, seal drafts and gaps where cold air reaches pipes, and disconnect garden hoses before winter. During a hard freeze, let a faucet drip slightly, open cabinet doors under sinks to let warm air reach the pipes, and keep the home heated even when you are away. These small steps prevent the vast majority of freeze-ups.

How a Home Warranty Fits In

Prevention and thawing are on the homeowner, but plumbing components can and do fail from normal wear and tear, and a home warranty is designed to help with those covered breakdowns. Rather than face an unpredictable repair bill, you file a claim, pay a predictable flat service fee, and a licensed plumber is dispatched for the covered repair. Pairing good winter prevention with coverage gives you both fewer emergencies and a plan when one strikes.
