Protecting Your Home from Frozen Pipes: A Homeowner's Winter Guide

Contact us now at: 360-761-9515

When temperatures drop, your plumbing system becomes vulnerable to one of winter's most costly hazards: frozen pipes. A frozen pipe can burst without warning, causing extensive water damage, costly repairs, and significant disruption to your home or business.

At Mast Plumbing & Mechanical, we help homeowners prepare for winter and avoid plumbing emergencies. Here's what you need to know about frozen pipes, how to prevent them, and what to do if your pipes freeze.

Why Do Pipes Freeze?

Pipes freeze when temperatures fall below 32°F (0°C) and the water inside them begins to turn to ice. As water freezes, it expands, creating pressure inside the pipe. This pressure can cause the pipe to crack or burst, leading to flooding when temperatures rise and water flow returns.

Pipes most at risk include:

• Outdoor hose bibs and faucets
• Pipes in crawl spaces and attics
• Garage plumbing
• Pipes running along exterior walls
• Uninsulated water lines
• Vacant or unheated properties

How to Prevent Frozen Pipes

Taking preventative measures before freezing weather arrives can save you thousands in repairs.

1. Disconnect Outdoor Hoses

Leaving hoses connected to exterior faucets can trap water inside the pipe and increase the likelihood of freezing. Disconnect and store hoses before temperatures drop.

2. Protect Outdoor Faucets

Install insulated faucet covers on exterior hose bibs to help reduce exposure to freezing temperatures.

3. Insulate Vulnerable Pipes

Pipe insulation is one of the most effective ways to protect plumbing located in:

• Crawl spaces
• Garages
• Attics
• Basements
• Exterior walls

Even inexpensive foam insulation can provide significant protection.

4. Keep Interior Temperatures Consistent

Avoid turning your thermostat too low during cold weather. If you're away from home, maintain indoor temperatures at a minimum of 55°F.

5. Open Cabinet Doors

Allow warm air to circulate around plumbing by opening cabinet doors beneath sinks, especially those located on exterior walls.

6. Let Faucets Drip

During extremely cold weather, allowing a faucet to drip slightly can help keep water moving through pipes and reduce freezing risk.

Signs a Pipe May Be Frozen

Recognizing the warning signs early can prevent major damage.

Watch for:

• Little or no water coming from a faucet
• Frost visible on exposed pipes
• Unusual odors coming from drains
• Loud banging or whistling sounds in pipes
• Sudden changes in water pressure

If you suspect a frozen pipe, act quickly.

What to Do If Your Pipes Freeze

Step 1: Turn Off Water to the Affected Area

If possible, shut off the water supply to reduce the risk of flooding if a pipe has already cracked.

Step 2: Locate the Frozen Section

Look for areas with visible frost or pipes exposed to cold air.

Step 3: Apply Heat Safely

Use:

• Hair dryers
• Heating pads
• Warm towels
• Portable space heaters (used safely and at a distance)

Never use:

• Open flames
• Propane torches
• Charcoal heaters
• Any device that produces direct fire

Step 4: Open Faucets

Keeping faucets open allows melted water to flow through the pipe and helps relieve pressure.

Step 5: Call a Professional

If you cannot locate the frozen section or suspect a pipe has burst, contact a licensed plumber immediately.

What Happens If a Pipe Bursts?

A burst pipe can release hundreds of gallons of water into your home in a short time.

If a pipe bursts:

1. Shut off your main water supply immediately.
2. Turn off electricity to affected areas if it is safe to do so.
3. Contact a licensed plumbing professional.
4. Begin water cleanup as quickly as possible to minimize property damage.

The faster you respond, the less damage your home is likely to sustain.
