Essential Tips to Prevent Your Pipes from Freezing This Winter

Winter brings cold temperatures that can cause serious problems for your home’s plumbing. Frozen pipes can burst, leading to costly water leaks and damage. Taking steps to protect your pipes now helps you avoid emergency repairs and keeps your home safe and comfortable throughout the season. This guide shares practical tips you can use to prevent frozen pipes and winterize your home effectively.

Open cabinet doors exposing exterior plumbing to warm air

Keep Cabinet Doors Open to Warm the Pipes

If you have plumbing pipes located in cabinets against exterior walls, such as under sinks, open those cabinet doors during cold weather. This allows warm air from your home to circulate around the pipes instead of trapping cold air inside the enclosed space.

For example, if your kitchen sink is on an outside wall, leaving the cabinet doors open during freezing nights can make a big difference. This simple step helps maintain a temperature around the pipes above freezing, reducing the risk of frozen pipes.

Let Water Drip to Prevent Freezing Pipes

Running water is less likely to freeze than standing water. When temperatures drop, turn on faucets connected to exterior plumbing or pipes in vulnerable areas to a slow drip. This keeps water moving and relieves pressure that can build up if pipes freeze.

You don’t need a strong flow—just a small, steady drip is enough. For instance, letting a faucet drip every hour or so during extreme cold spells can prevent frozen pipes in outdoor hose bibs or irrigation systems.

Open Heat Registers in Basements and Lower Levels

Basements and lower floors often have heat registers or vents that supply warm air. Make sure these registers are open and unobstructed during winter. Closing them can reduce airflow and allow cold air to settle around pipes, increasing the risk of freezing.

Check that furniture or storage items are not blocking heat registers. Keeping warm air flowing in these areas helps maintain a steady temperature around plumbing pipes, especially those near exterior walls or in crawl spaces.

Keep Garage Doors Closed to Block Cold Air

Garages are often attached to homes and may contain plumbing lines or water heaters. Leaving garage doors open lets cold air rush in, chilling pipes and increasing the chance of freezing.

Keep garage doors closed during cold weather to create a barrier against outdoor temperatures. If you have plumbing in the garage, consider adding insulation or heat tape to protect those pipes further.

Maintain Thermostat Temperature Above 55°F

Set your thermostat to stay above 55 degrees Fahrenheit, even when you are away or asleep. Lower temperatures inside your home can cause pipes in unheated areas to freeze.

Keeping your home warm enough prevents cold spots where pipes are vulnerable. This is especially important for homes with plumbing in attics, basements, or exterior walls. Avoid turning down the heat too much overnight or when you leave for extended periods.

Additional Tips to Winterize Your Home Plumbing

• Insulate Pipes: Use foam pipe insulation sleeves or heat tape on exposed pipes, especially those in unheated areas like crawl spaces or attics. This adds a layer of protection against freezing temperatures.

  
  

• Seal Gaps and Cracks: Check for drafts around windows, doors, and where pipes enter your home. Use caulk or weatherstripping to seal these openings and keep cold air out.

  
  

• Disconnect Outdoor Hoses: Remove garden hoses and drain outdoor faucets. Leaving hoses attached can trap water in pipes and increase freezing risk.

  
  

• Install Frost-Proof Faucets: Consider upgrading to frost-proof outdoor faucets that prevent water from sitting in exposed pipes.

  
  

• Know Your Main Water Shutoff: In case a pipe does freeze and burst, knowing how to quickly shut off your water supply can minimize damage.

  
  

What to Do If You Suspect Frozen Pipes

If you notice reduced water flow or no water coming from a faucet, frozen pipes may be the cause. Act quickly to prevent a burst:

• Open the faucet to allow water to flow as the pipe thaws.

• Apply gentle heat to the frozen section using a hair dryer, heating pad, or warm towels.

• Avoid open flames or high heat sources that can damage pipes.

• If you cannot thaw the pipe or detect a water leak, call a professional plumber immediately.

  
  

Taking these precautions helps you avoid costly repairs and water damage from frozen pipes.

Protect Your Home This Winter

By following these practical steps, you can protect your home from the dangers of freezing pipes. Opening cabinet doors, letting faucets drip, keeping heat registers open, and maintaining a warm thermostat are simple actions that make a big difference. Adding insulation and sealing drafts further winterizes your home plumbing.

Preventing frozen pipes requires attention before and during cold weather. Start early and stay consistent to keep your plumbing safe all winter long. If you prepare now, you’ll avoid the stress and expense of water leaks and damage later.
