A real person answers, day or night
The leak that shows up on your water bill, not your floor
A meter that keeps ticking with every tap shut off, a warm patch underfoot, a wall that never dries out, these are the quiet signs of a leak that stays hidden until someone looks for it.
Ground that moves is why the leaks here stay hidden
These streets follow an undulating shale ridge, and the reactive clay beneath swells and shrinks with each wet and dry spell.

How we track down a hidden leak
Finding a leak you cannot see is a process of narrowing down, so we combine listening gear, moisture readings and pressure checks until the exact spot is beyond doubt:
Acoustic leak detection
Pressurised pipes hiss where they leak, so we run acoustic listening gear across the floor and walls to hear the escaping water through tile, slab and brick, then flag the one spot the sound is loudest before anyone lifts anything.
Moisture and thermal
Damp leaves a trail even when it is invisible, so we take moisture-meter and thermal readings across suspect surfaces to map where water has spread, which narrows a vague damp patch down to the run of pipe actually at fault.
Meter and pressure test
Numbers confirm what the ear suspects, so we isolate sections and watch the water meter and a pressure gauge to prove whether a line is losing water and roughly where, before committing to opening any wall or slab at all.
Pinpoint and access
Once the source is found, we open only that small section, whether that means lifting a few tiles or cutting one neat access hole, so the repair and the making-good stay neatly contained rather than turning into a demolition job.
Not every hidden leak is inside the house
Plenty of the leaks we chase are outdoors, on the buried line running from the water meter at the front to the house.

Signs of a leak worth checking
A creeping water bill
A quarterly bill that jumps for no clear reason is one of the earliest hints of a hidden leak, and comparing a few recent statements against your actual usage usually confirms whether water is escaping somewhere out of plain sight.
Damp that won't dry
A patch of wall or floor that stays damp through dry weather points to water arriving from a leak rather than the weather, and finding its source stops the slow damage before it reaches the framing or the floor above.
Why finding a leak early pays off
A hidden leak is a slow, expensive problem dressed up as a small one, so tracing it early is the difference between a neat repair and a big bill:
- Damage compounds quietly Water tracking through a wall or slab rots timber and lifts flooring long before it shows, so the sooner it is found the less there is to repair.
- Bills bleed money A leak on a live supply line runs every hour of every day, so a small unseen weep can add up to a serious loss across a single quarter.
- A weep becomes a burst A weeping joint left alone only gets worse, and heading it off early avoids the flood of a full burst pipe down the track.
How it works
Our leak detection process, step by step
- 01
Call and tell us
Ring (02) 9072 0592 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Tracing it down
With the gear on-site, we work methodically from the meter inward, listening, reading moisture and isolating sections until the leak is pinned to one spot, then show you where it is and what the fix needs before any surface opens.
- 04
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why choose Your Plumber Mortdale
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Mortdale works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
This kind of careful tracing runs right through our plumbing side.
Where we work
Suburbs we reach beyond the home streets
The same leak detection travels to Penshurst, Oatley, Hurstville, Peakhurst and Allawah, older parts of the Georges River suburbs where concealed leaks inside walls and under slabs turn up for exactly the same reasons they do closer to home.
Good questions, straight answers
Leak detection questions Mortdale locals ask
Can you find a leak without digging up the whole yard?
Yes, acoustic listening, moisture readings and meter tests narrow a hidden leak to one spot, so we dig or open only where the water is actually escaping and nowhere else.
What are the first signs of a concealed leak?
A water bill that climbs for no reason, a meter that ticks with every tap off, a warm floor patch or a wall that stays damp all point to a hidden leak.
Why do the older homes here get hidden leaks?
The undulating shale ridge and reactive clay under these streets shift with the seasons, slowly prising old rigid joints open until a fitting deep in a wall or slab begins to weep.
Is the leak assessment free?
Yes, attending and reading the signs costs nothing because the call out is $0, and the fixed written cost of the trace is only set once you choose to proceed.
Will finding the leak damage my floors or walls?
No, the whole point of detection is to avoid that, because pinpointing the exact spot means one neat access point rather than opening wall after wall on a hunch.
Is the leak repair covered by a warranty?
Yes, every repair we make after tracing a leak is backed by our Lifetime Labour Warranty, so if the spot we fixed ever weeps again we return and put it right at no charge.
