Strategies to Prevent Your Pipes from Freezing During Extreme Cold
Each winter, homeowners face a silent threat lurking within their walls: frozen pipes. When temperatures plummet, the water inside pipes can freeze, expanding and potentially causing pipes to burst. Frozen can lead to extensive water damage and costly repairs. Fortunately, there are a number of strategies you can employ to protect your plumbing system during extreme cold periods. Let's explore these methods to keep your pipes flowing freely all winter long.
Understanding the Risk
Pipes begin to freeze when temperatures drop to 20°F (-6.7°C) or below for at least six consecutive hours. Pipes most at risk are those in unheated interior areas like basements, attics, and garages, as well as pipes running along exterior walls. Knowing which pipes are vulnerable is the first step in preventing freezing.
Insulation: Your First Line of Defense
Pipe Insulation
One of the most effective ways to prevent pipes from freezing is to insulate them properly. Pipe insulation is particularly crucial for pipes in colder areas of your home. You can use foam rubber or fiberglass sleeves to help maintain the water temperature inside the pipes. While insulation doesn't add heat, it helps retain the existing warmth in the pipes.
Types of Insulation:
• Foam pipe sleeves
• Fiberglass wraps
• "Pipe sleeve" insulation
Even newspapers can provide some degree of insulation for exposed pipes if you choose to take a DIY approach. However, for the best protection, consider professional-grade insulation materials.
Home Insulation
Beyond pipe-specific insulation, improving your home's overall insulation can help protect your plumbing. Add insulation to attics, basements, and crawl spaces to maintain higher temperatures in these areas. Home insulation protects your pipes and can lead to energy savings.
Temperature Control
Maintain Consistent Indoor Temperatures
During severe cold snaps, it's tempting to lower the thermostat to save on heating costs. However, this can be a costly mistake when it comes to your pipes. Keep your thermostat set to the same temperature both day and night, at least 68°F (20°C) at the same temperature day and night. This consistency helps prevent pipes in interior walls from getting too cold.
When You're Away
Don't entirely turn off the heat if you're planning to be away during cold weather. Set the temperature no lower than 55°F (13°C) to prevent freezing. This small expense can save you from returning to a flooded home due to burst pipes.
Keep Water Moving
Let Faucets Drip
When temperatures are extremely low, letting cold water drip from faucets served by exposed pipes can prevent freezing. Even a trickle of water through the pipe can help prevent it from freezing. Focus on faucets on exterior walls and in unheated areas.
Identify and Monitor Vulnerable Faucets
Take time to identify all faucets on the outer walls of your home. During extreme colds, turn these faucets on to a warm drip and monitor them regularly. If the drip slows, it could be a sign that freezing is beginning to occur.
Improve Circulation
Open Cabinet Doors
Pipes often run through cabinets along exterior walls. Open these cabinet doors during cold spells to allow warmer air to circulate around the plumbing. Leaving cabinet doors open is especially important for kitchens and bathrooms on exterior walls.
Open Interior Doors
Keep interior doors open throughout your house to allow heat to circulate more evenly. This includes doors to unheated rooms or areas where pipes are located, such as basements or attics.
Seal Drafts and Leaks
Cold air can enter your home through the tiniest openings, potentially freezing nearby pipes. Inspect your home for drafts, particularly around electrical wiring, dryer vents, and pipes. Use caulk or insulation to seal these gaps and keep the cold air out.

Outdoor Pipe Protection
Disconnect and Drain Outdoor Hoses
Before winter sets in, disconnect garden hoses and drain water from pipes leading to outside faucets. Disconnecting and draining hoses prevents water from freezing in these pipes and causing damage.
Install Outdoor Faucet Covers
Inexpensive foam covers for outdoor faucets can provide an extra layer of protection against freezing temperatures. These are readily available at most hardware stores and are easy to install.
Close Inside Valves
Close the inside valves to supply the outdoor hose bibs. Then, open the outside hose bibs to allow water to drain. Finally, keep the outside valve open so any remaining water can expand without breaking the pipe.
Garage Considerations
If you have water supply lines in the garage, keep the garage doors closed as much as possible during cold weather. Garages often have large amounts of concrete, which makes them particularly cold and increases the risk of pipe freezing.
Advanced Prevention Techniques
Heat Tape or Heat Cables
For persistently problematic areas, consider installing heat tape or heat cables. These products can be applied directly to pipes and provide heat to prevent freezing. Only use UL-listed products and follow the manufacturer's instructions carefully.
Pipe Relocation
In some cases, the best long-term solution might be to relocate exposed pipes to provide better protection from freezing. While this is a more extensive project, it can permanently protect problematic pipes.
Monitoring and Maintenance
Regular Inspections
Inspect your pipes regularly, especially before and during the winter months. Look for signs of frost on exposed pipes, which indicate imminent freezing.
Be Alert to Warning Signs
Pay attention to warning signs that your pipes might be freezing:
• Strange smells coming from drains or faucets
• No water or only a trickle when you turn on a faucet
• Frost on visible pipes
If you notice any of these signs, thaw the pipes immediately or call a professional plumber.
Emergency Measures
Despite your best efforts, you might still encounter a frozen pipe. If this happens:
• Open the faucet served by the frozen pipe to allow water to flow as the pipe thaws.
• Apply heat to the frozen section using an electric heating pad, hair dryer, or towels soaked in hot water.
• Never use an open flame device to thaw pipes.
• Call a licensed plumber immediately if you can't locate or access the frozen area or if your efforts don't work.
Preventing pipes from freezing during extreme cold periods requires preparation, vigilance, and quick action. Remember, the cost and effort of prevention are far less than the expense and inconvenience of dealing with burst pipes and water damage. With proper care and attention, you can keep your pipes flowing freely even in the coldest weather, ensuring a warm, dry, and comfortable home throughout the winter months.
