| Inside a wall or ceiling | $350–$850 | Cut open + patch drywall |

| Slab leak (under concrete) | $1,500–$4,000+ | Locate, jackhammer or reroute |
What affects the price
Access to the pipe
The repair itself is often minor — it is reaching the pipe that costs. Exposed pipes are cheap; leaks behind drywall, under floors or beneath a slab need demolition and making-good.
Pipe material and fix type
A pinhole in copper may be soldered or coupled quickly. Corroded galvanized steel usually means replacing a section, and repeated pinholes suggest a bigger repipe conversation.
Emergency vs scheduled
A burst pipe at midnight pays after-hours rates of 1.5–2× standard. If you can isolate the leak at a shut-off valve, waiting for a normal appointment saves real money.

Does homeowners insurance cover a leaking pipe?
Policies usually cover sudden water damage to the home, but not the pipe repair itself or damage from slow, long-term leaks. Document the leak and call your insurer early.
Is a small pipe leak an emergency?
If you can close a shut-off valve and contain it, it can usually wait for a standard appointment. Water you cannot stop, or water near electrical, is an emergency — shut off the main and call.
