How much does it cost to fix a leaking pipe or faucet in Phoenix, AZ?
Most everyday leaks — a dripping faucet, a leaking trap under a sink, a weeping supply line — are fixed in one visit for $150–$450 in Phoenix, AZ, parts included. The price climbs when the leak hides inside a wall or ceiling: add access and drywall patching, and the same repair can run $600–$1,200. A slow drip and a hidden in-wall leak are very different jobs, which is why locating it comes first.
Likely causes
- Worn faucet cartridge or washers — The classic drip — the seal that stops the flow wears out.
- Leaking trap or drain joint under a sink — The P-trap and slip joints loosen or corrode; usually a quick, cheap fix.
- Failed supply line or valve — Braided lines and shutoff valves age out — a small weep today is a burst risk tomorrow.
- Corroded pipe joint — Pinhole leaks at aging copper or galvanized joints; the pipe section gets replaced.
What you can check yourself
- Shut the fixture's water valve and see if the drip stops — that isolates faucet vs. supply.
- A trap leak you can reach: hand-tighten the slip nuts a quarter turn; if it still weeps, the washer's done.
- Photograph the leak and check your water meter — it tells you if there's a second, hidden leak.
Typical cost
Typical in Phoenix, AZ: $150–$450 for a faucet, trap, or supply-line leak fixed in one visit; in-wall or ceiling leaks $600–$1,200 with access and patching.
When to call a pro
Water staining a ceiling, a leak soaking a cabinet base, any leak you can't shut off, or a meter that moves with everything closed — that's hidden-leak territory; get detection before it becomes water damage.
