Your Pipe Just Burst: Do This Right Now
Every minute with water running means more damage. Move fast.
1. Shut off the main water valve. It is usually in the basement near the front of the house, close to where the water line enters from the street. Turn it clockwise (wheel-style) or perpendicular to the pipe (lever-style) until it stops.
2. Open faucets to drain remaining water. Start at the lowest floor and work up. This releases pressure and gets remaining water out of the lines.
3. Turn off the water heater. Heating an empty tank can damage the unit. Set it to the "vacation" or "pilot" setting.
4. Call a plumber. Have your address, the location of the burst, and whether you shut the water off ready when you call.
5. Start cleanup. Use towels, a mop, and a wet/dry vacuum to get water up as fast as possible. Water sitting on wood floors and inside walls for more than 24 hours creates mold conditions. Move furniture and valuables out of the wet area.
The average water damage insurance claim from a burst pipe is $10,849 nationally. Westchester and Fairfield County costs trend higher. Speed is the biggest variable between a $1,000 cleanup and a $10,000 remediation.
Pipes Frozen but Not Burst Yet
A frozen pipe that has not burst yet gives you a window to fix it without the water damage. You will usually know a pipe is frozen because the faucet produces little or no water even though the valve is open.
What to do:
Keep the faucet open. As the pipe thaws, water and steam need somewhere to go. A closed faucet builds pressure.
Apply gentle, indirect heat to the frozen section. Good options: an electric heating pad wrapped around the pipe, a hair dryer held 6 to 8 inches away and moved constantly, or towels soaked in hot water and wrung out.
Work from the faucet end toward the frozen section, not the other way around. Starting at the faucet lets thawed water drain out. Starting at the frozen center can trap water and pressure between two ice plugs.
Never use a propane torch, open flame, or high-heat paint stripper on pipes. The risk of fire and pipe damage is high, and the heat cannot be controlled carefully enough in a confined space.
If you cannot locate the frozen section, or if the pipe is inside a wall or under a floor where you cannot reach it, call a plumber. They have tools (including pipe heating equipment and thermal cameras) for exactly this situation.
If the pipe does not thaw within 30 minutes of applying heat, or if you hear cracking sounds while working on it, stop and call a plumber. The pipe may already have a fracture that has not opened into a full burst yet.

How to Prevent Frozen Pipes This Winter
Pipe freezing is almost entirely preventable. These are the steps that matter most.
Insulate exposed pipes. Foam pipe insulation costs $1 to $3 per linear foot and takes 10 minutes per section to install. Priority areas: basement crawl spaces, garage walls, pipes running along exterior walls, and any pipe in an unheated space. Pipe heating cables run $50 to $200 per cable for areas that consistently freeze.
Keep heat at 55 degrees minimum. Even when you leave town for the weekend. A $30 heating bill is cheaper than a $2,000 burst pipe repair and the water damage that follows.
Open cabinet doors. On cold nights, open cabinet doors under sinks that sit on exterior walls. This lets heated room air circulate around the pipes.
Let faucets drip. During extreme cold (below 20 degrees Fahrenheit), let the faucet farthest from where water enters the house run at a slow trickle. Moving water is harder to freeze than standing water.
Know your main shutoff location. Before anything goes wrong. If a pipe bursts and you shut the water off in 30 seconds instead of 10 minutes, the difference in damage can be thousands of dollars.
Disconnect garden hoses before the first freeze. Water trapped in an attached hose backs up into the outdoor faucet body. The faucet cracks. You will not notice until spring when you turn the water on and it sprays inside the wall instead of outside.
Older Homes Are at Higher Risk
All four counties in this region have substantial housing stock built before 1970. Pipe material matters.
Homes built before 1920 typically have lead or galvanized steel pipes. Both are at the end of their usable life. Galvanized pipe has a lifespan of 40 to 80 years, meaning pipe installed in 1950 may have only 10 to 20 years of useful life remaining at best.
Homes from the 1920s to 1960s mostly used galvanized steel for supply lines. These pipes corrode from the inside as they age, restricting flow and developing pinhole leaks. They are also more susceptible to cracking under freeze-thaw stress than newer materials.
Homes from the 1960s to 1980s commonly used copper, which is more durable but develops pinhole leaks at fittings and elbows over time, especially in areas with aggressive water chemistry.
Homes built after 1990 mostly use PEX (cross-linked polyethylene), which is flexible, freeze-resistant, and generally the most reliable residential pipe material available. It can still freeze and burst, but it tolerates expansion better than rigid pipe.
If your home is pre-1970 and you have not had the plumbing assessed recently, a plumber's inspection costs $100 to $300 and can identify pipes that are near failure before a winter emergency makes the decision for you.
Frequently Asked Questions
- How do I know if a pipe is frozen or just has low pressure?
- Turn on the affected faucet fully. If nothing comes out or only a trickle appears, and neighboring fixtures on the same line also produce no water, the pipe is likely frozen. Low pressure from a single fixture usually points to a clog or partially closed valve, not a frozen pipe. Check whether the cold water, hot water, or both are affected, which helps narrow down which section of pipe is frozen.
- Should I call my insurance company before or after I call a plumber?
- Call the plumber first to stop the damage. Once the water is off and you have a moment, call your insurance company to open a claim. Document everything with photos before cleanup begins. Most homeowner's policies cover sudden pipe bursts but not gradual leaks or pipes that froze because the homeowner left the house unheated. Report quickly, since many policies have a 24 to 72 hour notification window.
- My pipe is frozen inside a wall. Can I do anything myself?
- Not much without causing other damage. You can try a heating pad pressed against the wall surface in the area where the pipe runs, but the heat transfer through drywall is slow and unreliable. A licensed plumber with thermal imaging equipment can locate the exact frozen section and either heat it from outside or open the wall at the right spot. Guessing where to cut drywall is an expensive mistake.
- Does homeowner's insurance cover frozen and burst pipes?
- Usually yes for the resulting water damage, but coverage depends on the cause. Insurance covers sudden accidental damage, which includes pipes that freeze during a cold snap in a normally heated home. It does not cover pipes that froze because the heat was off, because the home was unoccupied for an extended period, or because of deferred maintenance. Read your policy's water damage exclusions before you need them.
- At what temperature do pipes actually freeze?
- Water freezes at 32 degrees Fahrenheit, but pipes in interior walls rarely freeze until outdoor temperatures drop significantly below that. Most plumbing experts put the risk threshold at 20 degrees Fahrenheit for pipes in interior walls and 28 degrees for pipes in exterior walls or uninsulated spaces. Wind chill does not affect pipes directly since they are not exposed to moving air, but extremely cold sustained outdoor temperatures can push cold deeper into building cavities than people expect.
