Hidden water leaks found and fixed across Hamilton and the Waikato — under concrete slabs, behind walls, in ceilings and in buried water mains. Find it first, dig once.
A dripping tap announces itself. A pinhole leak inside a wall, under a slab or in the buried main to your house doesn’t — it just quietly rots framing, lifts flooring, feeds mould and inflates your water bill month after month. By the time a hidden leak shows itself as a damp patch, it’s usually been running for a while.
Plumbway Ltd finds these leaks methodically. We start at the water meter, isolate the system section by section to narrow the loss down, and target the diagnosis so that when we do open something up, it’s one small hole in the right place — not exploratory demolition.
Detection-only services find your leak and then hand you a report — and you still need a plumber. Because Plumbway is a PGDB-licensed plumbing company, we close the loop: locate the leak, show you the evidence, quote the repair and, in most cases, fix it the same visit.
Suspected leak after hours, or water coming through a ceiling right now? That’s a job for our 24/7 emergency plumbing service.

The classic signs: a water bill that's risen with no change in usage, a water meter that keeps ticking over when everything in the house is off, damp patches or mould on walls and floors, the sound of running water in quiet moments, warm spots on a concrete floor (hot water line leaks), and unexplained drops in water pressure.
We work from the meter inward — isolating sections of the system to narrow down where the loss is happening, then using targeted diagnosis of the suspect area. The goal is to open up one small area, not to guess and cut multiple holes. You get an honest read on where the leak is and what fixing it involves before we start.
Yes. Buried mains between the council toby and the house are one of the most common sources of hidden water loss, especially on older Hamilton properties with galvanised supply lines. See our water main repair service for what happens once we've found it.
Not always, but it's the most common cause. A running toilet cistern can quietly pass hundreds of litres a day, and a pinhole leak in a pressurised line loses water around the clock. It's worth ruling out quickly — a leak check visit costs far less than months of inflated bills or a rotted floor.
Yes — that's the point of using a licensed plumber rather than a detection-only service. Once located, we repair it on the spot where possible: pipe repairs, toilet and tap overhauls, hot water cylinder valves, or full section replacements where the pipe has had its day.
