As temperatures drop, the risk of your pipes freezing becomes a serious concern, especially in Northern New Jersey, where freezing weather can cause significant damage to your plumbing system. Frozen pipes are a common yet preventable problem that many homeowners face during the winter months. When water in pipes freezes, it expands, which can lead to cracks or even bursts in your plumbing. This can cause severe water damage, expensive repairs, and inconveniences that could have been avoided.
Here’s what you need to know about preventing pipes from freezing in winter and protecting your home from the harsh cold.
Why Do Pipes Freeze in Winter?
Pipes freeze when temperatures drop below freezing, typically 32°F (0°C). Water inside pipes expands as it freezes, creating pressure inside the pipe. If the pressure gets too high, it can cause the pipe to burst. Most vulnerable pipes are those in exposed pipes or in areas where cold air can reach them, like attics, garages, and crawl spaces. In extreme cold weather, even plastic pipes and water supply lines can freeze and burst.
Frozen pipes can also lead to frozen water pipes that stop water flow. This is particularly common in homes with pipes running along exterior walls or areas not heated during winter. It’s essential to take steps to protect your plumbing before winter hits to avoid costly repairs and water damage.
How Do You Prevent Pipes from Freezing in Winter?
Knowing how to protect your pipes before winter hits can help you avoid emergencies and keep your home running smoothly. Below are simple, effective steps you can take to prevent frozen pipes during the coldest months.
1. Insulate Your Pipes
One of the most effective ways to prevent pipes from freezing is to insulate them. Pipe insulation helps maintain the temperature of the water flowing through them, keeping the pipes warmer during cold weather. There are several types of insulation, including foam sleeves and heat tape, which can be wrapped around exposed pipes. These materials are especially useful in areas like crawl spaces, attics, and garages.
- Pipe Insulation: Insulation prevents cold air from reaching the pipes. It’s available in foam, fiberglass, and rubber options.
- Heat Tape: Heat tape or thermostatically controlled heat cables are designed to warm the pipes in extremely cold temperatures. They provide heat directly to the pipe to keep the water from freezing.
2. Let Your Faucets Drip
When the temperatures drop to freezing levels, you can prevent frozen pipes by letting your faucets drip slowly. This ensures that water is still moving through the pipes, reducing the chance of freezing. Allow both hot and cold water to drip slowly from faucets served by vulnerable pipes. A trickle of water keeps it from freezing. Even a small amount of movement can prevent frozen water pipes.
3. Keep Your Home Warm
Maintaining warmer air inside your home helps prevent pipes from freezing. Keep your thermostat set to a consistent temperature throughout the day and night, even when you are away. If you live in a particularly cold area, you can use space heaters or portable space heaters in areas where pipes are exposed. Ensure that garage doors are closed and that areas like bathroom cabinet doors are open to allow heat to reach the pipes. If you’re leaving your home for an extended period, take a few simple steps to keep your pipes from freezing:
- Set your thermostat to at least 55°F (13°C). This helps maintain enough warmth to protect your plumbing while you’re away.
- Keep garage doors closed. This traps heat in areas where pipes often run, such as walls or ceilings connected to the garage.
- Open cabinet doors under sinks. Letting warm air circulate through pipes in kitchens and bathrooms helps prevent freezing.
4. Seal Drafts and Air Leaks
Sealing up any drafts or air leaks is another important step in preventing pipes from freezing. Cold air can slip through cracks in walls, windows, and doors, cooling the air around exposed pipes and increasing the risk of freezing. Check the areas where pipes enter or exit the house, and seal any air leaks with weather stripping or foam insulation. Use caulk or expanding foam to seal cracks or gaps in walls, particularly those around water supply lines or pipes running along exterior walls.
5. Disconnect Garden Hoses and Drain Water
Outdoor faucets and garden hoses are especially prone to freezing, so it’s crucial to disconnect and drain them at the start of winter. If you leave a hose attached to an outdoor faucet, water can remain in the hose or the faucet, which can freeze and cause damage to your water system.
To disconnect Garden Hoses, remove any hoses from outdoor faucets, and store them inside for the winter. Make sure to drain water from any garden hoses or outdoor faucets before freezing temperatures arrive.
What to Do if Pipes Freeze: Thawing Frozen Pipes Safely
If you discover that your pipes have already frozen, it’s important to take immediate action to avoid a burst pipe and minimize potential water damage.
1. Locate the Frozen Section
Start by identifying the frozen section of the pipe. Look for areas that are colder than the rest of the plumbing, such as pipes near exterior walls or crawl spaces. You may notice frost or condensation on the pipe, indicating that it’s frozen.
2. Thaw the Frozen Pipes Safely
Use a hair dryer to gently heat the frozen section of the pipe. Keep the dryer moving back and forth to avoid concentrating heat in one spot. You can also wrap the pipe with an electric heating pad wrapped around the frozen pipe to thaw it, but make sure to avoid using any open flame or flammable materials. Lastly, apply hot water to the pipe using towels soaked in hot water to gently heat it. Melt ice inside the pipe and allow the water to flow freely once the pipe has thawed.
3. Turn On the Faucet
Once you’ve thawed the pipe, turn on the faucet connected to it to let the water flow. This helps to prevent the pipe from refreezing.
Prevent Freezing Pipes When You’re Away
If you plan to be away for an extended period, take extra steps to protect your pipes from freezing. Set your thermostat to at least 55°F (13°C) to maintain warmth, then shut off the main water supply and drain any remaining water from the system. Turning off the main shutoff valve prevents water from entering the pipes while you’re away, reducing the risk of leaks or burst pipes. Taking these precautions ahead of time can help you avoid costly damage and unnecessary stress.
Conclusion
Preventing pipes from freezing is essential to protecting your home and avoiding expensive repairs. By taking proactive measures such as insulating pipes, keeping your home warm, and sealing drafts, you can safeguard your plumbing from the damage that freezing temperatures can cause.

FAQs
Should I let hot water or cold water drip to prevent pipes from freezing?
To prevent pipes from freezing, you should let cold water drip from the faucet. This helps keep the water moving through the pipes, which reduces the chances of freezing. Hot water doesn’t have the same effect since it’s more likely to remain in the pipes as it cools, making it less effective at preventing freezing. The key is to keep the water moving, so cold water is the better choice.
Does it matter if the house is cold, won’t cold water dripping just freeze?
Yes, the temperature of your home does matter. While cold water dripping can help prevent freezing, if your home is too cold (below freezing), the water in the pipes can still freeze. However, even in cold weather, allowing water to drip slightly from the faucet keeps the water in motion, which reduces the pressure buildup that leads to freezing. For maximum protection, you should keep the thermostat set to at least 55°F (13°C) and insulate exposed pipes to help prevent freezing.
How much should the water drip, little droplets or a small stream?
You don’t need a strong stream of water, but a small stream or a few droplets are enough to keep the water moving. A steady drip (just enough to see a continuous drop of water) can make a significant difference in keeping your pipes safe from freezing. Avoid letting it run full force, as that can waste water unnecessarily. A slow, consistent drip is the most effective solution.
Is it okay to just run cold water in multiple sinks to keep pipes from freezing?
Running cold water in multiple sinks can help, but it’s not as effective as dripping from one faucet that’s connected to vulnerable pipes. If your home has multiple open pipes, it’s a good idea to let the cold water drip from several faucets, especially those on exterior walls or in unheated areas, like basements or garages. Focus on the sinks that are most likely to freeze.
Should I open cabinet doors under sinks or other areas to help warm the pipes?
Yes, you should open cabinet doors under sinks or any cabinets where plumbing runs along exterior walls. Opening the cabinet doors allows warmer air from your home to circulate through the pipes, helping to prevent them from freezing. This is especially helpful in kitchens and bathrooms where water supply lines are typically near exterior walls. Make sure that the air around the pipes is warm enough, and if needed, use space heaters in those rooms to help maintain a safe temperature for your pipes.
