What to Do When a Pipe Bursts: Emergency Step-by-Step Guide
A burst pipe can release 50+ gallons of water per minute. Within an hour, you can have thousands of gallons of water saturating floors, walls, and subfloor. The damage can reach $15,000–$70,000 if not stopped quickly. These 7 steps, taken immediately, dramatically limit the damage.

Key Takeaways
- Step 1: Shut off the main water supply — this is the single most important action
- Every minute a burst pipe runs increases cleanup cost by $100–$500+
- Take photos and video before any cleanup — essential for insurance
- Even after stopping the flow, call an emergency plumber immediately
- You have 24–48 hours before mold begins growing in wet walls
Immediate Actions: The First 10 Minutes
- Shut off the main water supply valve. This stops all water flow to your home. Location: typically where the main water line enters the home (basement, crawl space, utility room) or in a box near the street meter. Turn clockwise to close.
- Turn off the water heater. With water supply off, the heater must be turned to "pilot" or shut off at the breaker to prevent damage.
- Assess electrical safety. If water is near electrical outlets, switches, or the main panel, shut off the circuit breaker for the affected areas before entering the space.
- Open faucets to drain remaining water. With the main shutoff closed, opening faucets helps drain remaining water from the supply lines — reducing how much continues to flow.
- Begin removing water immediately. Use towels, buckets, and a wet/dry vacuum. Every gallon removed now reduces drying time and mold risk later.
- Document everything before cleanup. Take extensive photos and video of all damaged areas, including ceilings, walls, floors, and affected belongings. This is critical for your insurance claim.
- Call an emergency plumber. The burst pipe must be repaired before water can be restored. Call 1-888-24-PLUMB for 24/7 dispatch.
Common Causes of Burst Pipes
| Cause | Most Common In | Prevention |
|---|---|---|
| Freezing (most common) | Cold climates, unheated areas | Insulate pipes, maintain indoor heat |
| Age and corrosion | Homes with galvanized steel pipes 40+ years old | Proactive repiping |
| Water pressure too high | All homes — high municipal pressure | Install pressure-reducing valve |
| Physical damage | During renovation, from shifting foundation | Careful renovation practices |
| Tree root intrusion | Older pipes near mature trees | Sewer camera inspection |

The Pipe Repair Process
After the emergency plumber assesses the damage, repairs typically involve:
- Locating the break — may require cutting drywall if the pipe is inside a wall
- Cutting out the damaged section and installing a coupling repair or new pipe segment
- Pressure testing the repaired section before restoring water
- Drywall patching — typically a separate contractor after pipes are confirmed repaired and dry
Emergency pipe repair costs $400–$1,500 for the plumbing work. Water damage remediation (drying, dehumidification, mold prevention) is typically $2,500–$15,000+ depending on extent.
The 24-Hour Mold Clock
Mold begins growing in wet building materials within 24–48 hours. After a burst pipe:
- Remove standing water immediately
- Increase air circulation (fans, windows if weather permits)
- Use dehumidifiers in affected areas
- Consider hiring a water remediation company — they have commercial drying equipment that reduces mold risk dramatically
- Wet drywall that cannot be dried in 48 hours should be removed and replaced
Frequently Asked Questions
In most homes, the main shutoff valve is located where the water supply line enters the house — typically in the basement near the front wall, in a utility closet, or in a crawl space. In warm climates, it may be outside near the water meter. Know this location before an emergency.
The pipe repair itself costs $400–$1,500 depending on pipe location (inside a wall is more expensive) and material. Water damage remediation adds $2,500–$15,000+. If caught within minutes and water removed promptly, restoration costs can be significantly lower.
If you cannot locate the main shutoff, call your water utility — they can shut off service at the street meter. You can also shut off water at individual fixture shutoff valves while you locate the main. Every home should have the shutoff location noted somewhere easily accessible to all family members.
Yes — most policies require prompt notification of a loss. Call your insurer the same day, even before you fully understand the extent of damage. An adjuster will assess and advise on the claim process. Keep all receipts from any emergency services.
