How to Prevent Frozen Pipes in Winter

Frozen pipes are a serious concern during cold weather. When water freezes inside pipes, it expands and can cause the pipe to crack or burst.

A burst pipe can release large amounts of water and cause extensive property damage.

Fortunately, there are several steps homeowners can take to reduce the risk of frozen pipes.

Insulate Exposed Pipes

Pipes located in unheated areas such as basements, garages, crawl spaces, and attics are especially vulnerable.

Insulating these pipes with foam pipe insulation helps retain heat and prevent freezing.

Keep Indoor Temperatures Consistent

Even if you leave your home for an extended period, avoid turning the heat off completely.

Maintaining indoor temperatures above 55°F (13°C) helps protect plumbing systems from freezing.

Let Faucets Drip During Extreme Cold

Allowing faucets to drip slightly during extremely cold temperatures helps keep water moving through the pipes.

Moving water is less likely to freeze than stagnant water.

Open Cabinet Doors

Pipes under kitchen and bathroom sinks may be located near exterior walls.

Opening cabinet doors allows warm air to circulate around the pipes and helps prevent freezing.

Seal Drafts Around Pipes

Cold air entering through cracks or openings can increase the risk of frozen pipes.

Check areas where pipes enter walls or foundations and seal gaps with insulation or caulk.

Disconnect Outdoor Hoses

Outdoor faucets are particularly vulnerable to freezing.

Before winter:

  • Disconnect garden hoses
  • Shut off exterior water valves if available
  • Drain outdoor faucets

This helps prevent water from freezing inside exterior plumbing.

What to Do if Pipes Freeze

If you suspect a pipe has frozen:

  1. Turn on the faucet connected to the pipe.
  2. Apply gentle heat using a hair dryer or heating pad.
  3. Never use open flames or torches.

If the pipe has already burst, shut off the main water supply and contact a plumber immediately.

Final Thoughts

Preventing frozen pipes is much easier than dealing with the damage caused by a burst pipe. With proper insulation, consistent heating, and simple winter precautions, homeowners can significantly reduce the risk of frozen plumbing during cold weather.
