Leak Detection Services in Grey Lynn

Grey Lynn is villa territory — 1900s–1920s weatherboard homes with original plumbing that has been patched, extended, and bodged by generations of owners and tradesmen. Behind the lath and plaster walls, under the timber floors, and beneath the concrete paths, old copper and galvanised pipes are corroding, joints are failing, and leaks are developing where you cannot see them.

The older homes on Surrey Crescent, Williamson Avenue, and the streets around Grey Lynn Park are prime candidates for hidden leaks. Decades of movement, tree root pressure, and corrosion take their toll. Even renovated villas can have leaks where new plumbing connects to old.

We approach leak detection in Grey Lynn knowing what these houses are built like. We know where pipes run in villas, where the weak points are, and how to find leaks without ripping out more wall than necessary. Find it, fix it, and keep your villa intact.

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 Grey Lynn homes.

Damp patches on walls or ceilings — moisture appearing where it should not be. Common in villas with lath and plaster.

Sound of running water — when everything is turned off, you should not hear water flowing.

Musty smell or mould — persistent dampness behind villa walls breeds mould you can smell before you see it.

Drop in water pressure — a leak in the supply line reduces pressure to the rest of the house.

Wet patches in the garden — a soggy area in the lawn or path that never dries, even in summer.

How We Find Leaks

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

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.
