Frozen Pipes How to Prevent, Thaw, and Repair Winter Pipe Damage

 

Why Do Pipes Freeze (and Why Does It Matter)?

Pipes freeze when temperatures drop below 20°F (-6°C), 

especially in unheated or poorly insulated areas of a home. 

The water inside the pipes turns to ice, expanding as it freezes. 

Since there’s nowhere for the built-up pressure to go, the pipe can crack or burst, releasing gallons of water into your home once it thaws.

The most at-risk pipes are usually in exterior walls, crawl spaces, attics, basements, and garages.

In older homes, pipes may be more vulnerable due to outdated insulation, while in newer homes, builders sometimes place plumbing in exposed areas without considering extreme cold temperatures.

Ignoring frozen pipes is never a good idea. 

Even if they don’t burst immediately, the pressure can create small hairline fractures, leading to slow leaks that go unnoticed until mold and water damage become a serious problem.

 

How to Prevent Frozen Pipes Before Winter Hits

Homeowners who take simple precautions before winter can often avoid costly repairs and water damage.

One of the most effective ways to prevent frozen pipes is to keep water moving during extreme cold. If temperatures drop significantly, leaving a small trickle of water running from your faucets can help prevent ice from forming inside the pipes.

Insulating exposed pipes in attics, basements, and crawl spaces is another critical step.

Pipe insulation is relatively inexpensive and can make a huge difference in protecting vulnerable areas.

Homes with plumbing in exterior walls should also ensure those walls are properly insulated.

Another mistake homeowners make is turning off the heat while traveling in winter. Even if you’re not home, keeping your thermostat set to at least 55°F (13°C) can help prevent freezing.

Disconnecting outdoor hoses and shutting off exterior water valves before temperatures drop is essential, too. Leftover water inside exterior pipes can freeze, expand, and cause pipes to burst inside the walls of your home.

If you’ve had frozen pipes before, consider installing heat tape or heating cables in areas prone to freezing. These devices provide low-level heat to pipes, keeping them above freezing temperatures.

What to Do If Your Pipes Freeze

If you turn on a faucet and nothing comes out, you likely have a frozen pipe somewhere in your plumbing system. The first step is to locate the frozen section—check under sinks, in basements, and along exterior walls for pipes that feel extremely cold to the touch.

Once you’ve found the frozen area, open the faucet connected to that pipe. This helps relieve pressure and allows melting ice to flow out as the pipe thaws.

Applying gentle heat is the safest way to thaw frozen pipes. A hairdryer, heating pad, or warm towels wrapped around the frozen section can gradually warm the ice inside.

Never use an open flame or propane torch—this can damage the pipe and create a fire hazard.

If you can’t find the frozen section, or if multiple faucets aren’t working, the frozen blockage may be inside a wall or underground. In this case, it’s best to call a professional to thaw the pipes safely and check for potential cracks or leaks.

 

Signs That a Frozen Pipe Has Burst (And What to Do About It)

Not all frozen pipes burst, but when they do, the damage can be devastating.

The most obvious sign is water leaking or spraying from a pipe once it thaws, but in some cases, homeowners don’t realize there’s a problem until they notice water stains on ceilings, damp drywall, or a musty odor from hidden mold growth.

In these cases acting fast is crucial to prevent further damage to your home.

If a pipe bursts in your home:

  • Turn off the main water supply immediately to prevent further flooding.
  • Shut off electricity in affected areas if water has reached outlets or appliances.
  • Move furniture and valuables away from standing water to minimize damage.
  • Call a water damage restoration professional to extract water, dry your home, and repair the damage.

Frozen Pipe Prevention, Thawing, and Repair Questions

Pipes become significantly at risk of freezing when outdoor temperatures drop below 20°F (-6°C), particularly in unheated or poorly insulated areas. In Denver’s climate, where overnight lows can drop rapidly after a warm afternoon, pipes located along exterior walls, in crawlspaces, attics, garages, or near poorly insulated exterior walls are most vulnerable during extended cold stretches.

Apply gentle, consistent heat starting from the faucet end and moving toward the cold section – never apply heat in the middle of a frozen section. Safe methods include an electric heating pad wrapped around the pipe, a hair dryer on low heat, or warm (not boiling) water-soaked towels. Never use an open flame, propane torch, or heat gun, as these can melt pipe material or ignite nearby materials. If the pipe has already cracked, stop and call a plumber.

The highest-risk pipes are those running through unheated crawlspaces, attics, garages, and along exterior walls – especially in rooms like laundry rooms and bathrooms adjacent to outside-facing walls. In newer Colorado homes, some plumbing is routed through exterior wall cavities with inadequate insulation. Older homes in Denver’s established neighborhoods may also have pipes in locations that didn’t account for modern heating standards.

Disconnect and drain all garden hoses, shut off and drain exterior spigots via their interior shutoff valves, insulate exposed pipes in crawlspaces and garages with foam pipe insulation or heat tape, and seal any gaps where cold air can enter around pipe penetrations. Set your thermostat to at least 55°F even when traveling, and leave cabinet doors open under kitchen and bathroom sinks to allow warm air to circulate pipes on exterior walls.

Turn off the main water supply immediately, then shut off power to any affected area at the electrical panel. Call a licensed plumber for the pipe repair and a water damage restoration company for extraction and drying. Do not wait – water from a burst pipe can release many gallons per minute, and even a short delay significantly increases structural damage, material saturation, and mold risk. Document all visible damage with photos before any cleanup begins.

Great experience. We had some relatively minor water damage to our hardwood floors. Called Anatom and Nate Johnson arrived within 45 minutes. Nate diagnosed the problem and clearly explained our options so that we could make in informed decision on how to proceed. Would use these guys again in a heartbeat.
Greg Plechaty
Super nice of them! I had a leak coming through my basement ceiling. Mike and Nate came out the same day and gave an honest and free assessment. They gave an honest opinion, which was instead of overaelling me, that the damage was limited. They used a moisture meter and thermal imaging, marked off the area of drywall to remove (fairly small), and texted mepictures of the thermal images.Both Mike and Nate were super friendly and personalble and patiently answered my questions. I was so thankful they were honest and helpful. I'd 100% recommend them and reach out to them again
William Geist
