A pipe burst and the house is flooding. What do you do first?
Shut off the main water valve. Then keep away from wet outlets, take photos, and get the water out.
- Close the main water shutoff valve. It's usually where the water line enters the house, often near the front hose bib or in the garage. Turn it until it stops.
- Drain the lines. Open a faucet at the lowest point of the house. That lets the water left in the pipes run out.
- Keep away from wet outlets and cords. Turn off the breaker for the wet area only if you can reach the panel without standing in water.
- Take photos and video of the break and the wet rooms before anything is moved.
- Keep the broken part. Don't throw away the split pipe, supply line or valve.
- Call a plumber and a restoration company. One fixes the pipe. The other removes the water and dries the house.

Why do pipes burst in Lancaster?
Mostly from freezing nights and aging pipes. Lancaster is in the high desert, and its winters are colder than many people expect.
Freeze season in the Antelope Valley
Lancaster gets about 61 nights at or below freezing between November and February. That figure comes from NOAA's 1991–2020 climate normals for the Fox Field weather station. December is the coldest month, with about 20 freezing nights.
In January 2025, Fox Field recorded lows of 15°F (NOAA daily records). Those were the coldest nights there since December 2020.
Water expands when it freezes. That puts pressure on the pipe until it splits. The leak often shows up when the pipe thaws, later in the morning.
Pipes in unheated spots freeze first:
- hose bibs and outdoor pipes
- pipes in attics and garages
- pipes along outside walls
- supply lines under mobile homes
Older homes and older pipes
Age matters too. In ZIP code 93534, around central Lancaster, about a quarter of homes were built before 1960 (U.S. Census Bureau, ACS 2020–2024). Older pipes and fittings may be closer to failing.
In a sample of Google reviews we read for Antelope Valley restoration companies, burst or broken pipes were the most-named cause. Reviewers mentioned supply lines, angle stops, hose bibs and shower pipes.
Mobile and manufactured homes
About 3,600 mobile homes sit in ZIP code 93535, east Lancaster and Lake Los Angeles (ACS 2020–2024). Quartz Hill has about 550 (ACS 2020–2024).
In a mobile or manufactured home, supply lines often run under the floor. There they are exposed to cold air and can freeze on cold nights. A burst under the home can soak the floor from below before you see water inside.
Supply lines, copper pipe and pinhole leaks
Not every break is a frozen pipe. A supply line failure is a break in the short hose that feeds a toilet, sink or appliance. These often fail at the fitting or the small shutoff valve (the angle stop).
A pinhole leak is a tiny hole in a pipe, often a copper pipe. It may spray or drip for a while before anyone notices. Damage from a slow leak like this can look different from a sudden burst, and insurers may treat it differently.
What if you can't see where the water is coming from?
Check your water meter. If every tap is off and the meter still moves, water is leaking somewhere.
Other signs of a hidden break:
- the sound of running water when nothing is on
- a wet spot on a ceiling or wall that keeps growing
- a water bill that jumps for no reason
- a warm spot on a slab floor
A leak in a line under the concrete floor is called a slab leak. A plumber finds and repairs it. See slab leak water damage.
Plumber or restoration company: who fixes what?
You usually need both. The plumber repairs the pipe. The restoration company removes the water, dries the house and handles the damage.
The pipe repair comes first, so the water stays off. Drying can start the same day if the water is shut off at the main.
Plumbing repairs may need a permit. The City of Lancaster's permits page says replacing a concealed pipe needs one. In unincorporated areas like Quartz Hill and Lake Los Angeles, permits come from LA County Building & Safety. Your plumber should know which applies.
How do you fix a burst pipe: temporary vs permanent?
A temporary fix only holds until a plumber arrives. A permanent fix replaces the damaged section of pipe.
Temporary fixes:
- Keep the main valve off. That is the safest temporary fix.
- A pipe repair clamp or repair tape can slow a small leak on an exposed pipe.
- Don't turn the water back on for long with only tape on the pipe.
Permanent fix:
- A plumber cuts out the damaged section and replaces it.
- After a freeze, ask the plumber to check nearby pipes. One cold night can crack more than one spot.
- If several sections fail, the plumber may suggest replacing more pipe.

Does insurance cover burst pipe water damage?
Usually yes, when the pipe bursts suddenly. Damage from a slow leak that went on for months usually is not covered. The final answer depends on your policy.
Homeowners policies generally cover water damage that is sudden and accidental, like a pipe that bursts without warning (Amica). The repair of the pipe itself may be treated differently from the damage the water caused. Read your policy or ask your agent.
You have the right to a copy of your policy. The California Department of Insurance says your insurer must send it free within 30 days of your request.
Why is your insurer asking for utility bills after freeze damage?
Your insurer may be checking whether heat was kept on. Many policies limit freeze coverage unless heat was maintained in the building, or the water was shut off and the pipes drained.
That wording comes from the common ISO homeowners forms (HO 00 03 and HO 00 05), as described by Rough Notes in 2018. Your own policy wording may differ. Gas or electric bills can show the heat was running during the cold snap. Give the insurer accurate records and an honest account of what happened.
Keep the failed part
Keep the split pipe, burst supply line or failed valve. Put it in a bag and label it with the date. Your insurer may want to see it. See water damage insurance claims in California for more on documenting a claim.
What happens after the water is out?
The house has to dry, and then damaged materials are repaired. The EPA advises drying water-damaged materials within 24 to 48 hours to prevent mold growth.
The steps usually go in this order:
- Water removal: see emergency water removal.
- Drying: fans and dehumidifiers run until moisture readings show materials are dry.
- Repair: drywall, flooring and cabinets that couldn't be saved are replaced. See water damage repair.
- Mold check: if anything stayed wet too long, see mold remediation.
For prices, see the water damage restoration cost guide.
How do you stop it happening next winter?
Keep the heat on during cold nights, and protect exposed pipes before November. Know where your main valve is before you need it.
