Frozen Water Pipes: How Do You Know and What to Do


Frozen water pipes can be a homeowner’s nightmare, especially during the cold winter months. Not only do they result in the inconvenience of having no water supply, but they can also cause significant damage to your plumbing system. However, detecting frozen pipes and taking prompt action can help prevent further damage and expensive repairs.

How Do You Know If Your Pipes Are Frozen?

There are several telltale signs that indicate your water pipes may have frozen. The most obvious sign is when you turn on a faucet and no water comes out. Another indicator is if you notice frost or ice on the exterior of exposed pipes. In some cases, you may also hear a strange hissing or gurgling noise coming from the pipes. Additionally, if you notice a decrease in water pressure or strange odors coming from the faucets, it could be a sign of frozen pipes.

What to Do If You Have Frozen Pipes?

If you suspect that your pipes are frozen, it is crucial to take immediate action to prevent further damage and minimize the risk of bursting. Here are the essential steps to take:

1. Keep the Faucets Open

Start by opening all the faucets in your home, including both hot and cold water taps. By doing this, it will relieve any pressure that may have built up in the pipes due to the freezing and expanding water. This step can prevent the pipes from bursting once they eventually thaw.

2. Locate the Frozen Pipes

The next step is to identify the area where the pipes are frozen. This can be a challenging task, especially if the pipes are hidden inside walls or ceilings. However, you can feel for cold spots or listen for hissing sounds, as frozen pipes often have gaps or cracks that allow air to escape.

3. Apply Heat to Thaw the Pipes

Applying heat to the frozen pipes is the most effective way to thaw them. You can use a hairdryer, a heating pad, or even a hot towel soaked in hot water. Make sure to start from the end of the pipe closest to the faucet and work your way towards the frozen section. Never use an open flame or a heat source with direct contact, as this could increase the risk of a fire or damage to the pipes.

4. Insulate the Pipes

Once the pipes have thawed, it is vital to address the root cause of the freezing issue to prevent future occurrences. One effective measure is to insulate the pipes with foam sleeves or heat tape. This will provide an extra layer of protection against freezing temperatures. Additionally, sealing any gaps or cracks in the walls or foundation of your home can help prevent cold air from reaching the pipes.

5. Contact a Professional

If you are unable to locate or thaw the frozen pipes, or if you suspect that there may be a burst pipe, it is best to contact a professional contractor immediately. They have the expertise and specialized equipment to handle the situation safely and effectively.

Prevention is Key to Avoiding Frozen Water Pipes

While knowing how to handle frozen pipes is crucial, preventing them from occurring in the first place is key. Here are a few prevention tips:

– Keep your home adequately heated during cold weather, even when you are away.

– Insulate exposed pipes in unheated areas, such as basements, crawl spaces, and attics.

– Keep cabinet doors open in areas where pipes are located to allow warm air to circulate.

– Let faucets drip slightly during extremely cold temperatures to keep water moving.

– Disconnect and drain any outdoor hoses or sprinkler systems before winter.

– Consider installing an automatic thermostat that can monitor and adjust the temperature in your home to help prevent freezing.


Frozen water pipes can cause significant damage if not addressed promptly. By knowing the signs of frozen pipes and taking immediate action, you can minimize the risk of bursting and subsequent water damage. Additionally, implementing preventive measures can help avoid future occurrences and provide you with peace of mind during the winter months.
