A burst pipe can dump gallons of water into your home every minute it runs, and it rarely happens at a convenient time. The good news is that what you do in the first few minutes matters more than how fast the plumber gets there — a handful of simple, correct steps can be the difference between a quick cleanup and a major repair bill.
Quick answer: If you have a burst pipe, shut off your home's main water valve immediately, then call a licensed plumber. Everything else — draining the lines, containing the water, protecting your floors — comes after those two steps.
Step 1: Shut Off the Main Water Valve
The single biggest factor in how much damage a burst pipe causes is how fast the water stops flowing. Every minute you wait is more water into your floors, walls, and belongings.
Your main shut-off valve is usually in one of these spots:
Inside: a basement, a utility closet, or under the kitchen sink
Outside: near the foundation, or in a curb box near the street
It's typically a round wheel handle (turn clockwise to close) or a straight lever (turn a quarter-turn until it's perpendicular to the pipe). If it won't budge, don't force it hard enough to snap it — that turns one emergency into two. Move to the next closest option, like a fixture-specific shut-off valve if the burst is isolated to one line.
Step 2: Cut Power to Wet Areas if Needed
If the burst pipe is near outlets, a breaker panel, or any electrical equipment, and it's safe to reach your breaker panel without stepping through standing water, shut off power to that area. If you'd have to walk through water to reach the panel, don't — wait for the plumber or an electrician instead.
Step 3: Drain the Remaining Water From the Pipes
Water already in the lines will keep draining out even after the main valve is closed. Open the lowest cold-water tap in the house to help that water drain out through the faucet instead of the break. If the burst is on the hot-water side, shut off your water heater and open a hot tap too — this protects the water heater and avoids scalding when the plumber starts work.
Step 4: Contain the Water and Limit Damage
Once the flow is stopped, it's about damage control:
Use towels, buckets, or a wet/dry vacuum to remove standing water
Set up fans or a dehumidifier to start drying the area
Move rugs, furniture, and anything else valuable out of the affected space
Standing water left for more than 24–48 hours is when mold risk really climbs, so this step matters even if you're waiting on a plumber. If the burst happened on an upper floor, check the ceiling and walls directly below it too — water travels along framing and can show up as a stain or drip in a completely different room than where the pipe actually broke.
Step 5: Document the Damage for Your Insurance Claim
Before you start cleaning up, take photos and video of the damage — the pooled water, affected walls and flooring, and anything damaged. Wide shots showing the full extent plus close-ups of specific damage both help. Most homeowner's policies cover sudden, accidental water damage like a burst pipe (though coverage details vary by policy), and having documentation from before cleanup started makes a claim much smoother.
Call your insurer as soon as you reasonably can — many policies also cover emergency mitigation costs (like a water-extraction service), so ask before you assume you're paying out of pocket. Keep any receipts for emergency repairs or temporary fixes, and write down a rough timeline of what happened while it's fresh — when you noticed the leak, what you shut off and when, and what steps you took. Adjusters often ask for exactly this kind of detail.
Step 6: Call a Licensed Plumber — Without the Cold-Call Scramble
This is usually the hardest part of a burst pipe emergency that nobody talks about: your house is flooding, and you're stuck cold-calling plumbing companies one by one, hoping someone actually picks up and can come out today.
Project Genie's Genie 911 emergency category was built for exactly this. Instead of calling around, you post your emergency plumbing job once, and licensed plumbers who are actually available bid for it — you get matched with one pro, not a dozen callbacks. You can see how we vet service professionals before you hire, so you know what to expect.
What NOT to Do During a Burst Pipe Emergency
Don't ignore a small leak hoping it stays small — pipe damage tends to get worse, not better, on its own.
Don't use electrical appliances near standing water.
Don't cut into walls yourself to "get a look" — let the plumber assess it; an amateur cut can turn a repair into a bigger one.
Don't turn the water back on to test whether it's fixed unless a professional has told you to.
Don't wait to call for help hoping it'll be cheaper tomorrow — water damage compounds by the hour.
Common Causes of Burst Pipes
Knowing why pipes burst helps you catch the next one early:
Freezing temperatures — water expands as it freezes and can split a pipe from the inside
Aging or corroded pipes — older galvanized or poorly-maintained lines weaken over time
High water pressure — consistently high pressure stresses joints and weak points
Tree root intrusion — roots can crack underground lines as they grow
Most of these build up slowly, which is exactly why a burst pipe often feels sudden even though the underlying cause had been developing for months or years.
How to Prevent This From Happening Again
A few habits go a long way:
Insulate any exposed pipes in unheated spaces (garages, crawl spaces, exterior walls)
Know where your main shut-off valve is before an emergency, not during one — point it out to everyone in the household
Have your plumbing inspected periodically, especially in an older home
If your water pressure feels unusually strong, ask a plumber to check it — a pressure-reducing valve is a small fix compared to a burst pipe

Frequently Asked Questions
How do I find my main water shut-off valve?
Check first near where the water line enters the house — a basement, crawl space, utility closet, or under the kitchen sink are the most common indoor spots. Outdoors, look near the foundation or in a curb box near the street. It's worth locating it now, before you ever need it in an emergency.
Is a burst pipe covered by homeowners insurance?
Most standard homeowner's policies cover sudden, accidental water damage from a burst pipe, though the details vary by insurer and policy. Damage from long-term neglect (like an ignored slow leak) is less likely to be covered, which is part of why acting fast matters. Check your specific policy or ask your insurer directly.
How fast can I get a plumber for a burst pipe?
That depends on your area and who's available right now — which is exactly the problem with cold-calling one company at a time during an emergency. Posting your job through Project Genie's Genie 911 emergency category lets available licensed plumbers come to you, instead of you chasing them down one by one.
Act Fast, Then Get Matched
A burst pipe is stressful, but the steps are simple: shut off the water, cut power if needed, drain the lines, contain the damage, document it for your insurer, then get a licensed plumber on the way. Post your emergency plumbing job free and skip the cold-call scramble.
