Leak Detection Kohimarama

Leak Detection Services in Kohimarama

Kohimarama's coastal location means salt air is constantly attacking your plumbing from the outside while water pressure and thermal cycling stress it from within. The result: accelerated corrosion on copper pipes, weeping joints, and pinhole leaks that develop faster than in inland suburbs.

Properties on Kohimarama Road, near Selwyn College, and along Tamaki Drive see this regularly. Character homes with original copper pipes are most at risk, but even newer homes can develop leaks where salt air gets to exposed fittings in roof spaces and under floors.

In a premium suburb like Kohimarama, water damage from a hidden leak can be devastating — not just structurally but to high-end finishes, timber floors, and plasterwork. Early detection is everything. We find leaks fast and fix them before the damage escalates.

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 Kohimarama 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.
