How to Prevent Frozen Pipes and Costly Bursts This Winter

1/31/2025 (Permalink)

As temperatures drop, one of the biggest risks homeowners and business owners face is frozen pipes. When water inside pipes freezes, it expands, creating pressure that can cause pipes to burst—leading to expensive water damage and repairs. Understanding why pipes freeze, how to prevent them, and what to do if you suspect a frozen pipe can save you from costly headaches.

Why Do Pipes Freeze?

Pipes are most likely to freeze when exposed to frigid temperatures (typically below 20°F), especially in:

• Unheated areas like basements, attics, garages, and crawl spaces
• Exterior walls with insufficient insulation
• Cabinets under sinks if located along an exterior wall

Once frozen, pipes can burst when the built-up pressure causes a rupture, resulting in significant water damage once the ice thaws.

How to Prevent Pipes from Freezing

Taking preventive measures before freezing temperatures hit is the best way to avoid costly damage. Follow these steps to keep your pipes safe:

1. Insulate Exposed Pipes

Wrap pipes in unheated areas with pipe insulation or foam sleeves. For added protection, use heat tape or thermostatically controlled heat cables.

2. Keep the Heat On

Even if you’re away, keep the heat in your home or business at a minimum of 55°F. The warmth helps prevent pipes from freezing.

3. Let Faucets Drip

Allowing a slow, steady drip from faucets connected to vulnerable pipes keeps water moving, reducing the risk of freezing.

4. Open Cabinet Doors

For sinks located on exterior walls, open cabinet doors to allow warm air to circulate around the pipes.

5. Seal Drafts and Cracks

Use caulk or insulation to seal gaps around windows, doors, and pipe openings to keep cold air out.

6. Disconnect Outdoor Hoses

Drain and store garden hoses, and shut off outdoor water supply valves. Use insulated faucet covers on exterior spigots.

What to Do If Your Pipes Freeze

If you suspect a frozen pipe, act quickly:

• Turn on the faucet to relieve pressure and determine if water is flowing at all.
• Apply heat using a hair dryer, heating pad, or space heater (never an open flame).
• Keep the heat going and open cabinet doors for airflow.
• Call a professional if you can’t locate or thaw the frozen pipe.

What to Do If a Pipe Bursts

A burst pipe can release hundreds of gallons of water per hour, causing serious damage. If a pipe bursts:

1. Shut off the main water supply immediately to stop the flow.
2. Turn off electricity if water is near electrical outlets or appliances.
3. Call a professional plumber for repairs.
4. Contact a water damage restoration company like SERVPRO to mitigate further damage and dry out the affected areas.

Protect Your Home or Business This Winter

A little preparation can go a long way in preventing frozen and burst pipes. Taking proactive steps now can save you from costly repairs, water damage, and business interruptions.
