Can Plumbers Unfreeze Pipes? By Sound Plumbing and Drain

How Long Does It Take to Unfreeze Pipes?

The time it takes to unfreeze a pipe depends on its location, the severity of freezing, and the weather. In most cases, it takes 30 minutes to a few hours for a pipe to thaw using safe heating methods.

• Exposed pipes (such as those under sinks) thaw faster because they are easier to access.
• Pipes inside walls or underground take longer since they retain cold temperatures longer and require indirect heating.
• Severely frozen pipes with solid ice blockages may take several hours or more to unfreeze.
• Extreme cold weather can slow down the process, especially if the temperature remains below freezing.

If a pipe remains frozen after an hour of thawing attempts, it’s best to call a plumber. They have the tools to speed up the process and check for damage that might not be visible.

Should You Try to Unfreeze Pipes Yourself?

In some cases, you can attempt to thaw a frozen pipe, but it must be done carefully to avoid damage.

DIY Thawing Might Work If:

• The pipe is easily accessible, such as under a sink or along an exterior wall.
• There are no visible cracks, leaks, or bulges.
• You use safe heat sources, such as a hair dryer, heating pad, or warm towels.

Call a Plumber If:

• The pipe is behind a wall, under flooring, or underground.
• Water is leaking or dripping from the pipe.
• The pipe remains frozen after trying safe thawing methods.
• You hear strange noises, such as whistling or banging, which could mean high pressure inside the pipe.

If thawing a pipe yourself, never use open flames, boiling water, or direct heat sources like propane torches. These can cause the pipe to burst or even start a fire.

Cost to Unfreeze Pipes

The cost of unfreezing a pipe depends on whether it’s a simple blockage or if repairs are needed.

• If the pipe is frozen but intact, a plumber may charge $100–$300 to thaw it.
• Emergency service calls, especially at night or on weekends, can increase costs.
• A burst pipe repair averages $500 but can go higher if water damage occurs.
• If the main water line is damaged, replacement can cost $1,000 or more.

Calling a plumber early can prevent costly repairs by stopping a small problem from turning into a bigger one.

What to Do If a Pipe Bursts

If a frozen pipe bursts, quick action can prevent flooding and major damage.

1. Shut off the main water supply – Locate your home’s shut-off valve and turn it off to stop water from flowing.
2. Turn off electricity if needed – If water is near electrical outlets or appliances, turn off power at the breaker.
3. Drain the faucets – Open all faucets to remove remaining water from the pipes.
4. Contain the leak – Use towels or buckets to catch leaking water and minimize damage.
5. Call a plumber immediately – Professional repair is needed to replace the burst section and check for additional damage.
6. Document the damage – Take photos for insurance purposes, especially if walls, floors, or personal items are affected.

Once the plumber repairs the pipe, take steps to prevent future freezing, such as insulating pipes and keeping the home heated above 55°F during winter.

How to Prevent Pipes From Freezing

Preventing frozen pipes is easier and cheaper than dealing with a burst pipe. Here are the best ways to keep your plumbing safe in cold weather:

1. Insulate Pipes

• Wrap exposed pipes in foam insulation sleeves, especially in basements, attics, and crawl spaces.
• Use heat tape on high-risk pipes for extra protection.

2. Keep Faucets Dripping

• Letting a faucet trickle during freezing temperatures keeps water moving, reducing the chance of ice forming inside pipes.

3. Maintain Indoor Heat

• Keep your thermostat set to at least 55°F, even if you’re away.
• Open under-sink cabinets to let warm air circulate around pipes.

4. Seal Gaps and Cracks

• Use caulk or spray foam to seal holes in walls, floors, and near pipes where cold air can enter.
• Check for drafts near windows, doors, and vents.

5. Disconnect Outdoor Hoses

• Drain garden hoses and shut off outdoor water supply lines before winter.
• Use faucet covers to protect outdoor spigots.

6. Winterize Vacant Homes

• If leaving your home for an extended time, shut off the water supply and drain pipes.
• Have a trusted neighbor check on your home during extreme cold spells.

Taking these steps can prevent expensive plumbing emergencies when temperatures drop.

Useful Additional Reading: Understanding the Risk of Frozen Pipes in Vancouver, WA, and Portland, OR

In the Vancouver, WA, area, temperatures can drop below freezing on approximately 46.7 days annually, posing a significant risk for frozen pipes. Best Places

Similarly, in Portland, OR, the cool season spans about 3.2 months, from November 15 to February 22, with average daily high temperatures below 52°F. WeatherSpark

During these colder periods, the likelihood of water pipes freezing and potentially bursting increases. The Portland Water Bureau notes that water mains are more susceptible to breaks during colder weather, which can lead to significant water damage and service disruptions.

To mitigate these risks, it’s essential to take preventive measures such as insulating exposed pipes, sealing gaps that allow cold air in, and maintaining a consistent indoor temperature. If you suspect your pipes are at risk or have already frozen, it’s crucial to act promptly.

Does Home Insurance Cover Frozen Pipes?

Whether insurance covers frozen pipes depends on the situation and your policy.

Usually Covered:

• If a pipe bursts due to sudden freezing and causes water damage inside your home.
• Damage to floors, walls, or belongings from the leak may also be covered.

Not Covered:

• If the insurer determines that negligence led to the damage, such as failing to heat the home.
• If the pipe burst due to wear and tear or poor maintenance.
• Outdoor plumbing, sprinkler systems, and swimming pool pipes are usually excluded from coverage.

What to Do:

• Review your homeowner’s insurance policy to understand what’s covered.
• Keep the heat on during winter, even if you’re away, to avoid claims being denied.
• If a pipe bursts, take photos of the damage and contact your insurance provider immediately.

While insurance can help with costs, prevention is the best way to avoid costly repairs and claims.

Common Myths About Frozen Pipes

There’s a lot of bad advice about dealing with frozen pipes. Here are some common myths and the facts you need to know.

Myth: Pipes only freeze in extremely cold climates.
Fact: Pipes can freeze anywhere, even in warmer states if temperatures drop unexpectedly. Homes in mild climates may be at greater risk because plumbing isn’t always insulated properly.

Myth: Pouring hot water down the drain will thaw a frozen pipe.
Fact: Pouring boiling water on or down a frozen pipe can cause it to crack or burst due to rapid expansion.

Myth: If the pipe isn’t leaking, it’s fine.
Fact: A frozen pipe can still be at risk of bursting when it thaws. Expanding ice weakens the pipe, so monitor it closely after thawing.

Myth: Open flames are the best way to thaw pipes.
Fact: Using a torch or open flame is extremely dangerous and can cause a fire. Safe heat sources like hair dryers, space heaters, and warm towels are much better options.

Myth: Letting faucets drip wastes too much water.
Fact: A small, steady trickle of water prevents freezing and costs far less than repairing a burst pipe and water damage.

Knowing the facts can help you avoid mistakes and keep your plumbing safe during winter.

Hiring a Plumber for Frozen Pipes

If your pipes are frozen and you’re not sure what to do, hiring a plumber is the safest option. A professional can unfreeze pipes quickly, check for damage, and prevent future issues. Not all plumbers are the same, so it’s important to choose someone with experience in frozen pipe repair.

What to Look for in a Plumber

✔ Licensed and Insured – A reputable plumber should be licensed and carry insurance to protect your home in case of accidental damage.
✔ Emergency Availability – Frozen pipes can lead to sudden bursts, so a 24/7 plumber is essential for fast response.
✔ Local Experience – Plumbers familiar with Vancouver, WA, and Portland, OR, understand the region’s cold-weather risks and how to prevent pipe freezing in the future.
✔ Specialized Tools – The right equipment makes a difference. Professional plumbers use pipe thawing machines, heat wraps, and leak detection tools to safely unfreeze pipes.
✔ Transparent Pricing – Ask for an upfront estimate to avoid hidden fees. Many plumbers charge a flat rate for thawing services.
