Winter can be tough on homes, and frozen pipes are one of the biggest cold weather headaches. A frozen pipe is more than an inconvenience. It is one of the leading causes of winter water damage, and if that pipe bursts, you can end up with soaked drywall, ruined flooring, and expensive repairs.
Here is a practical guide to why pipes freeze, how to reduce your risk, what to do if your pipes freeze, and how to respond if a pipe bursts and causes damage in your home.
Why Do Pipes Freeze?
Pipes freeze when the water inside them is exposed to prolonged cold temperatures and drops below 32°F. The risk is highest when:
- Temperatures stay below freezing for several hours or days
- Pipes are in unheated or poorly insulated areas such as crawlspaces, attics, soffits, basements, exterior walls, or garages
- There are air leaks that allow cold air directly onto pipes
As water turns to ice, it expands. That expansion puts tremendous pressure on the pipe. The pipe often bursts in the weakest section where the pressure builds. Once temperatures rise and the ice melts, that break becomes a major leak, and water can flow into walls, ceilings, and floors before you even realize there is a problem.
How To Help Protect Your Pipes From Freezing
You cannot control the weather, but you can make your home less vulnerable. A few preventative steps before and during cold snaps go a long way.
Insulate vulnerable pipes
Look for water lines running through unheated or drafty areas. Foam pipe sleeves or wrap insulation are inexpensive and easy to install. Pay attention to:
- Pipes along exterior walls
- Pipes in unheated basements, crawlspaces, and attics
- Pipes near garage doors or foundation vents
Even a basic layer of insulation can help buffer pipes from extreme drops in temperature.
Seal drafts and cold air leaks
Cold air that blows directly across pipes can freeze them quickly. Check for gaps around windows, doors, sill plates, hose bibs, and where pipes enter or exit the home. Seal with caulk or expanding foam where appropriate. This protects both your pipes and your energy bill.
Keep some heat moving
During very cold weather:
- Keep your thermostat at a consistent temperature, day and night
- Open cabinet doors under kitchen and bathroom sinks on exterior walls so warm air can reach those pipes
- In extreme cold, allow a small trickle of water to run from faucets supplied by vulnerable pipes. Moving water is harder to freeze than standing water.
Protect outdoor plumbing
Disconnect garden hoses and drain exterior hose bibs before winter. If you have shutoff valves for outdoor spigots, close those valves from inside and open the outdoor faucet to let any remaining water drain. Consider installing frost free sillcocks for long term protection.
How To Tell If Your Pipes May Be Frozen
Sometimes frozen pipes are silent. Other times there are clear warning signs:
- A faucet only drips or does not produce any water when turned on
- Toilets refill very slowly or not at all
- A section of exposed pipe looks frosty or has condensation in very cold weather
- You hear strange clanking or banging when water is turned on
If you suspect a pipe is frozen, act quickly. The sooner you address it, the better your chances of avoiding a burst.
What To Do If A Pipe Is Frozen
If you think a pipe has frozen but has not yet burst:
- Turn on the faucet connected to the frozen line. Even a small trickle helps relieve pressure and allows water to start moving when the ice begins to melt.
- Gently warm the frozen section of pipe. You can use a hair dryer, a portable space heater placed at a safe distance, or warm towels. Always keep heaters away from flammable materials and never leave them unattended.
- Start warming the pipe from the faucet end and work back toward the frozen area. This helps melting water escape and reduces pressure buildup.
Avoid open flames, torches, or anything that could start a fire. They can crack pipes, ignite nearby materials, and cause far more damage than the original freeze.
While you are working, keep an eye and ear out for leaks. If a pipe has already cracked, you may see or hear water once the ice melts.
What To Do If A Pipe Bursts
A burst pipe is an emergency. Water can spread quickly into walls, ceilings, insulation, flooring, and personal belongings. Acting quickly can reduce the damage.
Here are the key steps:
- Shut off the water supply. If you know which line is affected, turn off the valve to that line. If not, turn off the main shutoff valve to the home.
- Cut power if water is near electrical outlets, appliances, or your breaker panel. Safety comes first.
- Call a plumber immediately to repair the pipe.
- Start removing standing water if it is safe to do so. Use mops, towels, and wet dry vacs to pick up as much as possible.
- Begin drying the area. Open windows if temperatures permit, run fans and dehumidifiers, and move wet items to a dry space. Quick drying helps reduce the risk of mold and long term structural damage.
Even with fast action, water from a burst pipe often seeps into places you cannot easily see, such as wall cavities, under flooring, or inside cabinets. That is where winter damage claims can become complicated.
