Leak Detection Ellerslie

Leak Detection Services in Ellerslie

Ellerslie's mix of 1920s-1950s character homes and modern townhouse developments means leak issues span every era. The older villas and bungalows along Ladies Mile and near Ellerslie Racecourse often have original copper and galvanised pipes that have been corroding for decades.

Newer townhouses off Main Highway can develop leaks from poor workmanship during fast-tracked construction — joints that weren't properly soldered, or pipes stressed by building settlement.

Hidden leaks in Ellerslie homes cause the same damage regardless of the property age — rotting timber, mould, and wasted water. We pressure test and systematically narrow down the source, then fix it in the same visit where possible.

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 Ellerslie 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.
