What Are the Signs a Leak Is Hiding?

A hidden leak gives itself away slowly, through clues that are easy to blame on something else:

A quarterly water account climbing while the household carries on as normal
The meter dial creeping forward with the whole house shut off
A soft, damp or musty-smelling patch in one room
A cylinder that seems to run dry faster, a hint that a hot pipe is losing water
Paint lifting or plaster going soft on a wall where no pipe shows

Any one of those is worth a check. Found while it is still a damp patch, a leak is a small repair; left for a season, it can rot a floor frame.

How We Trace a Hidden Leak

Nothing gets pulled apart until the gear has done its job.

01
Start at the meter
All outlets are closed, and if the dial still moves, water is escaping; the speed of the dial gives a clue to how big the fault is.
02
Trace the pipe route
A pipe locator maps where the supply lines actually run under the slab, the garden and the walls.
03
Listen for the escape
An acoustic leak detector is moved along that route to catch the sound of water leaving the pipe, and the loudest spot is marked.
04
Open the smallest area
Only the marked spot is opened for the repair, so you lose a tile or a patch of lawn rather than a whole wall.

Where the water is escaping from a waste pipe instead, see CCTV drain inspection for how the camera finds it.

What Moves the Price of a Leak Search?

We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.

Leak work is priced on these:

Slab, wall or garden: where the escape sits decides how much has to be opened
A single search visit or a longer hunt across several lines
One joint remade, or a length of pipe replaced
Galvanised steel that is rusting through may need a longer run renewed, not just a patch

Low Ground, Old Pipes and Salt Air

Wet ground on the low blocks

Rathmines sits at about 7 metres above sea level, and the blocks nearest the foreshore hold groundwater. Buried galvanised fittings in that damp soil rust from the outside, and the reactive clay moves as it wets and dries, stressing joints.

Old houses, mixed pipe

Postwar cottages clad in weatherboard or fibro sit alongside brick veneer and newer homes, so one house can join galvanised, copper and plastic pipe. Each change of material is a joint that can weep.

Brackish air outside

Salty lake air along the waterfront corrodes garden taps and exposed fittings early, so a tap that looks fine can still be the slow loss the meter shows.

What a Customer Said

[The team] came to our home to inspect a water leak yesterday. … They were able to identify and service the leak and were happy to talk us through the process.

When We're Not the Right Call

Water that only drips through during rain is a roof or gutter fault for a roofer. A shower that leaks through its base because the waterproofing membrane has failed needs a builder or waterproofer. Any whiff of gas goes to gas leak detection, with everyone out of the house first.

Leak Questions From Rathmines Homes

How can I tell if the leak is under the slab or inside a wall?

A floor that feels warm underfoot suggests a hot pipe losing water under the slab, while a soggy skirting board or lifting paint suggests a wall pipe. The pipe locator and acoustic detector confirm which, down to one length of pipe, before anything is opened.

Do you find leaks on the western shore as well as in Rathmines itself?

Yes. Leak tracing covers Kilaben Bay, Coal Point, Fishing Point, Balmoral and Buttaba, with the same detector and locator used in each, and the repair priced before it starts.

Will finding the leak mean tearing up my floors or garden?

No. Tracing narrows the escape to one short length first, so only that spot is opened. If it lies under a garden bed or a concrete path, the quote spells out exactly what has to come up before it starts.

Is a slowly rising water bill always a leak?

Not always. A dripping tap or a toilet that keeps refilling can lift the account on its own, and both are quick to rule out. If the meter still moves with every outlet shut, water is escaping out of sight, and tracing is the next step.
