What to Do When a Pipe Bursts: Six Steps to Take Right Away
A burst pipe can flood a home in minutes, so when a pipe bursts, stop the water first and then handle everything else.
- Shut off the main water supply. This stops new water from entering the pipes.
- Turn off electricity to affected areas only if it is safe. Never step into standing water near electrical outlets, fixtures, or appliances.
- Open faucets to relieve remaining pressure. This drains water still sitting in the lines.
- Contain leaking water and protect belongings. Use towels, buckets, and bins, and move valuables to dry ground.
- Call a professional emergency plumber. A burst pipe is not a DIY job. For fast help in Denver, see our Emergency Plumbing Services Denver page.
- Document the damage for insurance. Take photos and video before you clean up.
Freezing temperatures, aging pipes, corrosion, and high water pressure are the most common causes of a pipe bursting. In Colorado, a cold snap can split an exposed line.
A leak inside a wall may not be visible at all. Watch for damp drywall, peeling paint, musty smells, or a sudden jump in your water bill. Our Leak Detection & Repair Denver service can help identify hidden leaks.
Here is a quick reference for the six steps, with the timing or detail the article gives for each.

How to Shut Off the Main Water Supply
Your main shut-off valve is usually in the basement, crawl space, or near where the water line enters your home. Turn the handle clockwise until it stops. If the valve is stuck, do not force it with a tool. Call a plumber instead.
Know where this valve is before an emergency happens. Call us if you are unsure where to find it.
Signs of a Burst Pipe in a Wall
A burst pipe inside a wall often shows up as water damage before anyone sees a puddle. Our professional leak detection and repair service can pinpoint hidden plumbing problems. Check for soft spots in flooring, warm patches on walls, or a drop in water pressure. If your water bill rises with no obvious leak, hidden plumbing may be the cause.

Frequently Asked Questions
What will happen if pipes burst?
A burst pipe releases water under pressure, which can soak drywall, flooring, insulation, and furniture within minutes to hours. Standing water can also damage electrical outlets and wiring, and moisture left behind can lead to mold growth. Shutting off the main water supply quickly and calling an emergency plumber limits how far the damage spreads. Document the damage as you go so you have records for your insurance claim.
Who is responsible for a burst water pipe?
Responsibility usually depends on where the pipe is located. Lines inside your home are generally the homeowner’s responsibility, while the section between the street and your home may be the utility’s or your own, depending on local rules. Check your property documents or contact your water provider to confirm where the line is divided. Your homeowners insurance policy will also determine what damage is covered, so review it or call your agent after you have stopped the water.
When should I call an emergency plumber for a burst pipe?
Call an emergency plumber as soon as you have shut off the water and it is safe to do so. You should call right away if water is still flowing, if you cannot find or close the shut-off valve, if water is near electrical outlets or appliances, or if you see signs of a leak inside a wall or ceiling.
