A $150 drip today is a $15,000 wall next winter.
Leak repair splits in two. Visible leaks are a straightforward standard-hours booking at published hourly rates. Hidden leaks, the ones behind walls, under slabs and under driveways, are a detection job first: acoustic and thermal gear finds the leak so the hole gets cut once. The expensive version of this stream is always the leak nobody looked for.
Is this your stream?
A dripping tap, a leaking trap under the sink, a damp patch on a wall, or a toilet that keeps running. Book it in standard hours; none of these need an after-hours surcharge.
A Watercare bill that jumped, a meter moving with everything off, or warm spots on a slab floor point to a hidden leak. That needs a detection specialist with acoustic or thermal gear before anyone cuts anything open.
What it costs in Auckland
The published repair rate
Matthews Plumbing & Gasfitting publishes $120+GST per hour plus a $60+GST admin, vehicle and sundries charge, one-hour minimum then 15-minute blocks. Most visible leak repairs land inside the first hour or two.
The no-callout alternative
Response Plumbing advertises a $0 callout fee with an upfront written quote before work starts, which shifts the risk of a small job onto a fixed number rather than an open hourly meter.
Detection work
Acoustic and thermal detection is quoted per job, separate from the repair. It feels like an extra cost until you price the alternative: cutting three holes in a gib wall or breaking out a driveway on a guess.

Common mistakes
Ignoring the water bill clue: an unexplained jump in your Watercare bill is often the first sign of a hidden leak. Check the meter with everything off; if the dial still moves, water is going somewhere and a detection visit is cheaper than the ongoing bill.
Paying emergency rates for a contained drip: a leak you can isolate at a fixture is a standard-hours booking. Matthews' published $120+GST/hr plus $60 beats any after-hours surcharge for the same repair.
Digging or cutting before detecting: guessing the leak path under a concrete driveway or inside a wall is expensive. Your Local Plumber runs acoustic gear and Call A Plumber runs thermal imaging precisely so the hole gets cut once, in the right place.
Patching the symptom in an old pipe: Auckland's older suburbs still have ageing galvanised supply pipes. A pinhole repair on 60-year-old pipe is often money spent delaying a repipe; ask about the state of the run, not just the leak.
Forgetting the body corporate: in an apartment or townhouse, a leak inside a wall may be in common property, and the repair cost may not be yours alone. Tell the body corporate before you book destructive investigation.
Not documenting for insurance: photograph the damage, keep the detection report and the invoice. Insurers routinely ask for evidence of both the leak and the repair.
FAQ
How much does leak repair cost in Auckland?
Visible leaks bill at standard plumbing rates: Matthews publishes $120+GST per hour plus a $60+GST admin and vehicle charge, and Auckland trade cost guides put first-hour charges at $120–$190+GST. Hidden leak detection with acoustic or thermal gear is quoted per job; the detection fee is usually separate from the repair that follows.
How do I know if I have a hidden leak?
A water bill that jumps without explanation, a meter that moves with every tap off, damp or warm patches on floors and walls, mould in odd places, or the sound of water when nothing is running. Any of those justifies a detection visit before the damage compounds.
What does leak detection actually involve?
Acoustic detection listens for the sound of escaping water through pipes and surfaces; thermal imaging cameras spot temperature differences from leaking hot or cold water. Both locate the leak without opening the wall or slab first, which keeps the repair surgical instead of exploratory.
Is a leak ever an emergency?
Yes, when water is actively spreading and you cannot isolate it: turn the water off at the toby and book an emergency callout. A contained drip under a sink or a slow stain on a ceiling is a standard-hours job and will cost noticeably less.
Who pays in an apartment or townhouse?
It depends on where the leak sits. Pipes serving only your unit are usually yours; common property pipes and building envelope issues sit with the body corporate. Report it to the body corporate manager before commissioning destructive investigation, because cost-sharing follows the unit plan, not who spotted the stain.
Visible leak: book standard hours at Matthews' published $120+GST/hr plus $60, or take Response's $0 callout with an upfront written quote. Hidden leak: meter test first (free), then a detection specialist; Your Local Plumber runs acoustic gear, Call A Plumber runs thermal imaging, EPS carries the job through to the repair. In a body corporate unit, report before you cut.
