Understanding Why Pipes Burst During Freezes
Pipes burst during cold weather because water expands when it freezes. When water inside your pipes turns to ice, it takes up more space. This puts pressure on your pipes from the inside.
Most pipes aren’t made to handle this extra pressure. When the pressure gets too high, the pipe cracks or bursts open. This usually happens at the weakest points in your plumbing system.
The pipes most likely to burst are those in unheated areas like basements, attics, and exterior walls. When the ice inside eventually melts, water rushes out through the broken pipe. This is why many homeowners discover pipes burst after temperatures start to rise.
Immediate Steps When Pipes Burst
Shut Off the Main Water Valve
The very first thing you should do when pipes burst is turn off your home’s main water supply. This stops more water from flowing into your home.
Your main water shut-off valve is usually located in the basement, crawl space, or near where the water line enters your home. It might be near your water meter. Make sure everyone in your family knows where this valve is before an emergency happens.
Turn the valve clockwise (right) until it’s fully closed. If you can’t find the main shut-off valve, call a plumber right away.
Turn Off Electricity to Affected Areas
Water and electricity are a dangerous mix. Go to your breaker box and turn off power to any rooms that have water in them.
If you can’t safely reach your breaker box, call an electrician or your power company for emergency help. Never step into standing water if you think electricity might be running to that area.
Your safety comes first when pipes burst. Water damage can be fixed, but electrical shocks can be deadly.
Call a Professional Plumber
Once you’ve stopped the water and made the area safe, call a plumber for emergency service. Pipes burst during freezes happen to many people at once, so plumbers get very busy.
Call as soon as possible to get on their schedule. Be clear that you have an emergency with pipes burst due to freezing.
While waiting for the plumber, take photos of all damage for your insurance company. This will help with your claim later.
Draining Your Plumbing System
After you’ve shut off the main water valve, you need to drain the water that’s still in your pipes. This helps reduce further damage when pipes burst.
Turn on all cold water faucets in your home. Start with the lowest faucets (usually in the basement) and work your way up. This lets gravity help drain the pipes.
Flush all toilets once or twice to remove water from the tanks and bowls. If you have a water heater, turn it off and let it cool before draining it according to the manufacturer’s instructions.
Don’t forget outdoor faucets if they’re not already frozen. Open them to drain any remaining water in those lines too.
Starting the Cleanup Process
Removing Standing Water
The sooner you remove water, the less damage you’ll have. Use towels, mops, and buckets to soak up standing water when pipes burst.
For larger amounts of water, a wet/dry vacuum can be very helpful. If you don’t own one, you can often rent them from hardware stores.
Work from the edges of the water toward the center. This helps prevent water from spreading to dry areas. Remove wet items like rugs, furniture, and personal belongings to dry areas.
Drying Out the Space
After removing standing water, you need to dry the space completely. Use fans to circulate air throughout the wet areas.
If you have dehumidifiers, set them up to pull moisture from the air. Open windows if the weather permits, but only if it’s not still freezing outside.
Move furniture away from walls and prop up cushions to allow air to circulate. Pull back carpeting if possible to dry the padding underneath.
Complete drying can take several days, but it’s important to prevent mold growth after pipes burst.
Documenting the Damage
Take clear photos and videos of all damage caused when your pipes burst. This includes damage to:
- Walls, floors, and ceilings
- Furniture and appliances
- Personal belongings
- The burst pipes themselves
Make a detailed list of damaged items with their approximate value. Include the date you purchased them if you know it.
Keep all receipts for emergency repairs, cleanup supplies, and replacement items. Your insurance may cover these costs.
Don’t throw away damaged items until your insurance adjuster has seen them or told you it’s okay to dispose of them.
Contacting Your Insurance Company
Call your homeowner’s insurance company as soon as possible after pipes burst. Most policies cover water damage from burst pipes, but coverage details vary.
Ask your agent what your policy covers and what your deductible is. They’ll explain the claims process and what documentation you need.
Some insurance companies have emergency response teams that can help with cleanup. Ask if this service is available to you.
Be prepared to show the adjuster all damage and your documentation when they visit. The more organized you are, the smoother your claim will go.
Temporary Repairs for Burst Pipes
While waiting for a plumber, you might need to make temporary repairs to pipes burst during the freeze. This can help prevent more water damage if you need to turn the water back on briefly.
For small cracks, pipe repair clamps from hardware stores can work as a short-term fix. These clamps have a rubber sleeve that goes around the pipe and metal bands that tighten to seal the leak.
For larger breaks, you might use pipe repair tape or epoxy putty. These products can temporarily seal holes until professional repairs are made.
Remember that these are only temporary fixes. You’ll still need a plumber to properly repair or replace the damaged pipes.
Preventing Future Pipe Bursts
Insulating Vulnerable Pipes
To prevent pipes from bursting in the future, insulate pipes in unheated areas. This includes pipes in:
- Basements and crawl spaces
- Attics
- Garages
- Exterior walls
Foam pipe insulation sleeves are inexpensive and easy to install. Just cut them to length and slip them over your pipes.
For extra protection in very cold areas, consider using heat tape or heating cables. These products provide warmth directly to pipes during freezing weather.
Maintaining Proper Home Temperature
Keep your home heated to at least 55°F (13°C), even when you’re away. This helps prevent pipes burst incidents during cold snaps.
Don’t turn your thermostat down too low at night or when you’re not home. The money you save on heating costs will be much less than the cost of repairing water damage.
If you’ll be away during winter, ask a friend or neighbor to check your home regularly. They can alert you to problems before pipes burst and cause major damage.
Allowing Faucets to Drip
When temperatures drop below freezing, let faucets drip slightly. Moving water is less likely to freeze than standing water.
Focus on faucets connected to pipes on exterior walls or in unheated spaces. Both hot and cold water should drip.
Even a small trickle can prevent pressure buildup in pipes. This simple step can save you from dealing with pipes burst during extreme cold.
When to Call Professionals vs. DIY
Some water damage cleanup can be handled yourself, but know when to call professionals. DIY is usually fine for:
- Small amounts of water (less than an inch deep)
- Water that hasn’t been standing long
- Areas without valuable or delicate items
Call professional water damage restoration services when:
- Water is deep or covers a large area
- Water has been standing for more than 24 hours
- Water might contain sewage or chemicals
- Valuable items or electronics are damaged
- You see signs of mold growth
Professional services have specialized equipment to thoroughly dry your home and prevent mold. They can also help with insurance claims when pipes burst causes significant damage.
Frequently Asked Questions About Burst Pipes
How quickly can pipes burst in freezing temperatures?
Pipes can burst within 4-5 hours of exposure to freezing temperatures. The exact time depends on pipe material, insulation, and how cold it gets. Pipes in unheated spaces like attics or exterior walls freeze faster than those in heated areas.
Will homeowners insurance cover burst pipes?
Most homeowners insurance policies cover water damage from pipes burst during freezes. However, they might not cover damage if your home was left unheated or if the damage resulted from poor maintenance. Check your specific policy and talk to your agent about your coverage.
Can I prevent pipes from freezing without heat?
If your heating system fails, you can temporarily protect pipes by:
- Opening cabinet doors to allow warm air to reach pipes under sinks
- Using space heaters (safely) in vulnerable areas
- Letting all faucets drip
- Adding extra insulation around pipes
These measures help but aren’t as effective as proper heating.
How do I know if my pipes are starting to freeze?
Warning signs of freezing pipes include:
- Reduced water flow from faucets
- Strange smells from drains or faucets
- Frost visible on exposed pipes
- Unusual sounds when using water (banging or clanking)
If you notice these signs, take action immediately to thaw pipes before they burst.
Protect Your Pipes Before They Burst
Dealing with pipes burst during a freeze is stressful, but quick action can minimize damage. Remember to shut off your water immediately, turn off electricity to wet areas, and call a professional plumber.
Document everything for insurance purposes and start cleanup as soon as possible. The faster you remove water, the less damage you’ll have to repair.
Prevention is always better than dealing with an emergency. Take time before winter to insulate vulnerable pipes and know where your main water shut-off valve is located.
