How Much Does Burst Pipe Repair Cost?

What burst pipe repair costs in 2026: accessible vs in-wall, copper vs PEX, emergency vs scheduled. Plus what's repair and what's a whole-house issue.

A burst pipe is two problems: the failed pipe (cheap) and the damage from however many gallons it dumped before you shut the main (expensive). The repair pricing in this guide assumes the water is off and the cavity is dry. If those aren't true yet, stop reading and shut your main first — every minute you delay multiplies the eventual claim. Once the immediate damage is contained, here is what the actual repair should cost in 2026.

Repair Types

By symptom and fix

$450–$1,250

Frozen-burst supply line

Symptom

Lengthwise split, usually 1–3 feet of pipe affected.

Typical fix

Cut out the affected section, replace with PEX or copper, add insulation.

$650–$1,850 section

Pinhole leak (copper corrosion)

Symptom

Green halo around a small spray, often in horizontal runs.

Typical fix

Patch is short-term; whole-section repipe is the real fix.

$1,850–$4,200

Slab leak

Symptom

Hot spot on floor, mystery water bill jump, sound of running water.

Typical fix

Reroute through attic in PEX — cheaper than jackhammering slab.

$325–$625

Burst hose bib (outside spigot)

Symptom

Water inside the wall behind the spigot after a freeze.

Typical fix

Replace with frost-free hose bib, slope downward.

$450–$950

Mechanical damage (nail or screw)

Symptom

Sudden leak after hanging artwork or running cable.

Typical fix

Patch with coupling; ensure no other damage in same run.

$425–$850

Cracked main shutoff

Symptom

Valve weeps when closed, won't stop water.

Typical fix

Replace with quarter-turn ball valve; coordinate with utility.

Repair vs Replace

When to fix it. When to replace it.

Repair if

+Single isolated failure (mechanical damage, freeze, accident)
+Pipe material is otherwise sound (copper without pinhole pattern)
+Repair restores normal pressure and shows no other weak points
+Home is under 25 years old with original PEX in good condition
+Insurance is covering the repair scope only, not a repipe

Replace if

×Multiple pinhole leaks within 12 months (corrosion is systemic)
×Polybutylene piping (failure rate is near-certain)
×Galvanized steel still in service (rusting from inside out)
×Repeated freeze failures in same locations despite insulation
×Slab leaks under copper — second one means repipe through attic

Rule of thumb

One burst pipe is bad luck. Two within a year on the same system means the pipe material itself is the problem — repair money is wasted at that point. A whole-house PEX repipe is the most underrated investment in homes with pre-2000 copper or any polybutylene.

Frequently Asked

Real homeowner questions

Is a burst pipe repair covered by homeowners insurance?+

The water damage is usually covered (subject to deductible). The pipe repair itself often isn't — most policies treat it as a maintenance issue. Frozen-pipe damage is covered IF you can demonstrate you kept heat on. Mitigation costs (drying, drywall removal) are usually covered.

Should I repair in copper or PEX?+

PEX, almost always. It's freeze-tolerant (expands instead of bursting), faster to install, and cheaper. Use copper only where code requires it (some commercial applications, exposed runs in mechanical rooms). All major DMV jurisdictions accept PEX for residential.

How long should a burst pipe repair take?+

Accessible: 1–3 hours. Behind drywall with single opening: 3–6 hours. Behind tile: half-day to full day. Slab reroute through attic: 1–2 days. Schedule the drywall/tile patcher separately — most plumbers don't do finish work.

What if my pipes burst while I'm away on vacation?+

Set your thermostat to 55°F minimum (not off), insulate exterior wall pipes, and consider a smart water shutoff with leak detection ($350–$650 installed). The cheapest insurance against a vacation burst is a $25 cabinet-door wedge keeping under-sink doors open during cold snaps.

Are 'whole-house' repipes worth the cost?+

Yes if you have pre-1985 copper with pinhole leaks, polybutylene (gray plastic with brass fittings), or galvanized steel. A PEX repipe runs $8,500–$16,500 but eliminates 95% of future repair calls and adds 4–6% to home value. Not worth it on otherwise-sound modern copper or PEX.
