Freeze damage often stays hidden until temperatures rise and the ice inside a pipe begins to melt. Preparing for a freeze means protecting vulnerable plumbing before the cold arrives, knowing how to stop the water quickly, and checking for leaks as the home warms.
The City of Wylie warns that winter storms can bring extreme cold, ice, high winds, and disruptions to heat and power. An exposed supply line, outdoor faucet, or pipe in an unheated garage can quickly become a source of water damage.
How Frozen Pipe Damage Appears After a Freeze
Water expands when it freezes, placing pressure on pipes and fittings. A pipe can crack below freezing yet remain quiet because ice blocks the opening. As the ice melts, water can escape through the damaged area.
Check under sinks, around water heaters, near exterior walls, in garages, and in accessible attic spaces for dripping water, wet insulation, staining, frost, or a sudden drop in water pressure. If no one will be home as temperatures rise, make sure the person checking the house knows how to shut off the main water supply.
Protect Outdoor Plumbing Before a Freeze
Outdoor hose bibs and plumbing in unheated spaces receive little protection from indoor heat. Prepare these fixtures before freezing weather arrives.
Start with these exterior checks:
- Disconnect and drain garden hoses from outdoor faucets.
- Cover outdoor hose bibs with insulated faucet covers.
- Insulate accessible water lines in the garage, attic, crawl space, or along exterior walls.
- Seal gaps around pipes where they enter the home to reduce exposure to cold air.
Pipe insulation slows heat loss, but it doesn’t replace monitoring during a long freeze or power outage. Pay particular attention to insulation that’s missing, loose, wet, or compressed near exposed plumbing.
Keep Indoor Pipes Warm & Water Moving
Warm air needs to reach plumbing exposed to outdoor temperatures. Open kitchen and bathroom cabinet doors when sink pipes sit against exterior walls, while keeping cleaners and other hazards away from children and pets.
During freezing conditions, the Texas Department of Insurance recommends letting both hot and cold faucets drip or running water through indoor faucets before bed. Moving water is less likely to freeze in a vulnerable line. Keep the garage door closed during a cold snap, and leave the home’s heat on if you’re away.
Insulation, caulking, and weather stripping help keep cold air from entering the home. These measures are especially useful when high winds make indoor areas colder than expected.
Locate & Test Your Main Water Shutoff
The main valve is the fastest way to limit damage if a pipe splits. Every adult in the household should know where it’s and how to operate it before freezing weather begins.
Find the valve, clear away anything blocking access, and confirm that it turns without being forced. If it’s difficult to reach, seized, or unable to stop the water completely, arrange to have it addressed before an emergency. Individual fixture shutoffs are also useful, but the main supply valve takes priority when water is actively leaking.
If water stops flowing from a fixture during a freeze, shut off the main supply before the pipe thaws. This can prevent a hidden crack from releasing water into the home. Record the valve’s location in your household emergency plan.
What to Do If a Pipe Freezes or Leaks
No water flow during a freeze can indicate a frozen supply line. A frozen pipe could already be cracked, so don’t assume the problem is resolved simply because water begins flowing again when temperatures rise.
Take these steps based on what you find:
- No Water Flow
Turn off the main water supply if you suspect a frozen pipe, then arrange for the line to be assessed before it thaws. - Visible Leak Or Spraying Water
Shut off the water immediately. Move belongings away from the area if it’s safe, and avoid electrical appliances or outlets near the water. - Frozen Accessible Pipe
Never use an open flame to thaw a pipe. It creates a serious risk of fire and overheating, and a cracked pipe can begin leaking as the ice melts.
A burst pipe near electrical equipment requires extra caution. Don’t use electrical heating appliances around a wet or spraying pipe because water reaching the appliance creates an electrocution risk. If water damage occurs, document the affected areas and consult your homeowners insurance carrier about your policy terms.
Make Freeze Preparation a Household Routine
Before temperatures drop, protect exterior fixtures, insulate accessible exposed lines, keep indoor plumbing areas warm, and test the household’s main shutoff. Continue monitoring vulnerable areas after temperatures rise, when hidden damage can become an active leak.
