The $200 drip and the $20,000 drip look identical at first.
Leak repair splits cleanly in two. Visible leaks (taps, mixers, traps, flexi hoses) are standard-hours bookings at standard rates. Hidden leaks (damp patches, musty smells, a meter that never stops) go to detection first, because finding the leak is a different skill from fixing it, and Christchurch has a firm with a dedicated detection division. The only wrong move is ignoring it.
Is this your stream?
Dripping taps, running cisterns, weeping joints, damp patches, a water bill that jumped, or a meter that moves with everything off. Book standard hours, fix it properly, keep the invoice.
What it costs in Christchurch
The typical visible repair
At Christchurch guide rates of $100–$140 an hour plus a $60–$90 callout (Flow Pro 2025), a straightforward tap, mixer, cistern or trap repair usually lands between $120 and $250 all up. Washers are cheap; access is the variable.
Detection work
Locating a hidden leak with acoustic or thermal gear is specialist time and is quoted after assessment. It feels expensive until you price the alternative: multiple exploratory holes in gib, flooring and your patience.
The meter test
Turn every tap and appliance off, then watch your water meter for ten minutes. If it moves, you have a leak, and you have just done the first hour of detection yourself. Tell the plumber the result; it shortens the billable hunt.

Common mistakes
Ignoring a small leak because it is small: a $5 washer left for a year becomes swollen cabinetry and a rotten floor. Walton's own advice is blunt about it: do not put off a small leak today, because it can be a huge problem tomorrow.
Paying emergency rates for a drip: a tap that drips or a cistern that runs is a standard-hours booking at $100–$140 an hour in Christchurch guide rates, not a $150–$300 emergency callout. Isolate it, bucket under it, book the morning.
Not reading your water meter: the cheapest leak detection in Christchurch is your own meter. Turn every tap and appliance off, watch the dial for ten minutes, and if it moves you have a leak somewhere. That one check tells the plumber where to start.
Cutting into walls before locating the leak: hidden leaks should be located before they are opened up. Clyne & Bennie runs a dedicated detection service for exactly this; an exploratory hole in the wrong place is your cost, not theirs.
Forgetting the post-quake question: in suburbs that took ground movement, a new leak in old pipework can be movement damage rather than wear. If your home had quake repairs, check what pipework was replaced before paying to chase symptoms.
Not asking for the paperwork: sanitary plumbing is restricted work, and the repair should come from a PGDB-registered plumber with the right certification. A cash-job patch on a hidden leak is how small problems become insurance disputes.
FAQ
How much does leak repair cost in Christchurch?
Visible leaks are charged at standard plumbing rates: Flow Pro's 2025 data puts Christchurch at $100–$140 per hour plus a $60–$90 callout, so a straightforward tap, mixer or trap repair typically lands around $120–$250. Hidden leaks that need detection work are quoted after assessment, and the repair itself depends on what the detection finds.
How do I know if I have a hidden leak?
The reliable signs: a water bill that jumps without explanation, a meter that keeps moving with everything off, damp or warm patches on floors or walls, mould or a musty smell in one spot, and the sound of running water when nothing is on. Any one of those justifies a detection visit before anyone cuts a hole.
Who fixes a leak under a concrete slab?
Slab leaks are located first (acoustic or thermal detection, which Clyne & Bennie's detection services division handles) and then either accessed through the slab or bypassed with new pipework overhead. The bypass is often cheaper and less disruptive than breaking the floor, so ask for both options priced.
Is a leaking hot water cylinder a leak repair job?
No. A cylinder leaking from the tank body is a replacement, not a repair, and it belongs in the hot water stream. Turn the water off at the toby and treat it as urgent, because a cylinder that is weeping today can let go properly tonight. Foleys and Walton both run 24/7 lines for exactly this.
Can I claim leak damage on insurance?
Sudden and accidental damage (a burst pipe) is usually covered; gradual damage from a leak you ignored often is not. Insurers routinely decline claims where a leak clearly ran for months. Fix small leaks promptly, keep the plumber's invoice, and photograph the damage before cleanup if you are claiming.
Visible leaks: book standard hours with ACF, Plumbquick or Laser Christchurch East and expect roughly $120–$250 at Christchurch guide rates. Hidden leaks: do the meter test, then call Clyne & Bennie's detection services before anyone cuts a hole. Water spreading or a leaking cylinder tank: toby off and call Walton or Foleys on their 24/7 lines. Fix small leaks promptly, because gradual damage is the part insurance declines.
