Burst pipe repair
A burst pipe can release hundreds of gallons an hour. What you do before anyone arrives matters more than how fast they get there.

Do these three things now, in this order
- Shut off the main water valve. Usually where the supply line enters the house — basement, crawlspace, garage, or an outside box near the street. Turn clockwise until it stops. If you can't find it, this guide walks through every common location.
- Open the lowest faucets in the house. This drains the remaining pressurized water downward and away from the break instead of out through it.
- Cut power to affected areas at the breaker — but only if you can reach the panel without standing in water. If you can't, leave it and call your utility.
Video the water at its worst. Get the standing water, the ceiling, the soaked belongings, the source if you can see it. Insurance adjusters assess from evidence, and once you've mopped up, that evidence is gone permanently. This is the single most valuable five minutes of the whole event.
Why pipes burst
| Cause | What it looks like | Who it affects |
|---|---|---|
| Freezing | Split along the length of the pipe, often in an exterior wall, attic, crawlspace, or unheated garage | Cold climates, and warm climates during rare freeze events — where it does the most damage because homes aren't built for it |
| Corrosion | Pinhole leaks, often several over months | Galvanized steel (pre-1960s) and older copper in areas with aggressive water chemistry |
| Water pressure | Sudden failure at a joint or fitting | Homes without a pressure regulator, or with a failed one. Above 80 psi is too high |
| Physical damage | A clean break at one point | Anyone who's driven a nail or screw into a wall, or had trenching done in the yard |
| Age and joint failure | Weeping or dripping at a soldered or threaded joint | Any system past ~50 years |
What the repair involves and costs
Access drives the price far more than the pipe does. The same six-inch section of copper can be a $250 job or a $2,500 job.
| Situation | Typical cost | Why |
|---|---|---|
| Exposed pipe (basement, crawlspace, garage) | $200–$600 | Cut, clean, and fit a repair coupling or new section. Often under an hour |
| Inside a finished wall or ceiling | $600–$1,800 | Drywall has to come out, the repair made, then pressure-tested. Drywall and paint are usually a separate trade and a separate bill |
| Under a concrete slab | $1,500–$5,000+ | Locating, breaking concrete, repairing, backfilling, re-pouring. See slab leaks |
| Main water line to the street | $1,500–$6,000 | Excavation or trenchless replacement, plus permits and often a utility coordination fee |
| Multiple simultaneous failures | Repipe territory | Several bursts in a short window usually means the system, not the pipe. Get a second opinion before committing |
The plumbing repair is often the smaller number. Drying, dehumidification, and replacing drywall, insulation, and flooring commonly runs $2,000–$8,000 for a moderate event. Sudden pipe bursts are typically covered by homeowners insurance — call your insurer the same day, not next week.
Frequently asked questions
What do I do first when a pipe bursts?
Shut off the main water valve. Everything else is secondary — every minute the water runs adds to the damage. Then open low faucets to drain the system, cut power to wet areas if it's safe to reach the panel, and photograph everything before cleaning up.
Can I repair a burst pipe myself?
Temporary patches — a repair clamp or pipe tape — can slow a leak enough to buy time, and they're worth having in the house. They are not repairs. A patched pipe under pressure can fail again suddenly and the second failure is often worse. Have it properly repaired.
Does homeowners insurance cover a burst pipe?
Most policies cover sudden and accidental water damage, which a burst pipe usually is. They typically exclude damage from gradual leaks, poor maintenance, or freezing in a home left unheated. Document immediately and notify your insurer the same day. Check your own policy — we're a referral service, not insurance advisers.
How long does a burst pipe repair take?
An accessible pipe: often under two hours. Inside a wall: half a day or more once you include opening up, repairing, and testing. Under a slab or in the main line: one to several days. Emergency visits frequently stabilize tonight and schedule the permanent repair for standard hours at standard rates.
What if I can't find my main shutoff valve?
Check the perimeter of the basement or crawlspace on the street-facing side, near the water heater, in the garage, or in an outdoor box at the property line. If you still can't find it, your water utility can shut supply at the street — their emergency line is on your water bill. Finding and testing your shutoff before you need it is one of the highest-value ten minutes a homeowner can spend.
