Leak Detection Belmont

Leak Detection Services in Belmont

Belmont's solid North Shore housing stock — mostly built between the 1950s and 1970s — means a lot of original copper pipework is still in service. The North Shore is well known for copper pinhole leaks, where pitting corrosion develops inside pipes over decades, eventually creating tiny holes that leak behind walls and ceilings.

Properties along Lake Road, up around Eversleigh Road, and near Belmont Primary are particularly susceptible — the combination of aging copper, ground movement, and decades of thermal expansion takes its toll on pipe joints and fittings.

Hidden leaks in Belmont homes can waste thousands of litres and cause serious damage — rotting framing, lifting flooring, and mould behind walls. The longer they go undetected, the more expensive the repair. We locate leaks accurately before opening walls or digging — saving you money and avoiding unnecessary damage.

Types of Leaks We Find & Fix

Hidden Pipe Leaks

Leaks inside walls and ceilings from corroded copper, failed joints, or pinhole corrosion. Common in older Auckland homes.

Slab & Underground Leaks

Water pipes running under concrete slabs or through the ground can leak for months before you notice. We locate and repair or reroute.

Hot Water System Leaks

Leaking cylinders, weeping valves, and dripping relief pipes. We diagnose whether it is a repair or replacement job.

Toilet & Fixture Leaks

Silent toilet leaks waste thousands of litres. Leaking shower trays and basins cause floor rot. We find the source and fix it.

Signs You Have a Hidden Leak

—

Unexplained high water bill — the #1 sign of a hidden leak in Belmont homes.

—

Damp or discoloured walls — water is getting in from somewhere.

—

Sound of running water — when everything is turned off, you shouldn't hear water.

—

Warm spots on floor — could be a hot water pipe leaking under the slab.

—

Musty smell or mould — persistent moisture behind walls breeds mould.

—

Water meter spinning — turn everything off and check your meter. If it's still moving, you have a leak.

How We Find Leaks

Leak detection is part science, part experience. Here is how we approach it:

Visual inspection — we check the obvious places first. Cylinder, valves, visible pipework, fixtures, and fittings. Sometimes the source is right there.
Pressure testing — we isolate sections of your plumbing and test them under pressure. If a section loses pressure, the leak is in that zone. This narrows the search quickly.
Meter check — with everything turned off, we watch your water meter. If it is still ticking over, water is going somewhere it should not be.
Targeted investigation — once we have narrowed it down, we open up the smallest area possible to confirm the source and make the repair. We do not rip out walls unnecessarily.

Most leaks are found and fixed in a single visit. For complex underground or slab leaks, we may recommend rerouting the pipe above ground rather than digging up concrete — it is often faster, cheaper, and avoids the same problem recurring.
