Leak Detection Glenfield

Leak Detection Services in Glenfield

Glenfield's housing stock — mostly built between the 1960s and 1980s — means a lot of original copper pipes are still in service and approaching the end of their lifespan. The North Shore is particularly prone to copper pinhole leaks, and Glenfield is no exception.

Homes on Bentley Avenue, up around Donaghys Hill, and along Glenfield Road regularly present with unexplained damp patches, high water bills, or the sound of running water when everything is off. These are the classic signs of a hidden leak.

Older earthenware drains in Glenfield also develop leaks at joints where tree roots have infiltrated — not just causing blockages but allowing wastewater to escape into the ground. We find all types of leaks and fix them properly.

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 Glenfield 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.
