A real person answers, day or night
The leak you cannot see is still doing damage every day it runs
A stain that grows, a bill that climbs or a wall that smells musty is water speaking from somewhere unreachable, and Carlton's oldest streets make guessing expensive, so we trace first and open second. Call (02) 9072 0520.
Why brick cottages keep a leak quiet
- Brick and weatherboard hold water Federation and interwar cottages built in double-brick and weatherboard absorb moisture deep inside wall cavities before anything shows on the surface, so by the time paint bubbles, the leak has often run for months.
- Galvanised fails along its length Supply pipes in cottages that have dodged renovation corrode from the inside across metres of run rather than at one obvious joint, which is why we pressure test whole lines instead of chasing a single drip.
How we find your leak
Finding a hidden leak is a discipline, not a guess: every method below exists to prove where the water is going before a single tile comes off, because exploratory demolition is the most expensive detection tool ever invented. It sits within the broader plumbing work we carry out across the area.
Acoustic and thermal tracing
Sensitive listening gear hears water escaping through brick, concrete and soil, while thermal cameras map the damp trail it leaves, and together they narrow most hidden leaks to a patch smaller than a dinner plate, keeping the repair opening tight.
Pressure testing the lines
Isolating each supply run and watching which line loses pressure identifies the guilty pipe without guesswork, which matters here where corroded old galvanised sections and newer copper often share the same journey from the meter to your taps.
Underground leak location
Buried runs get traced carefully with pipe locators, and where the fault sits in a drain, a CCTV drain inspection shows the crack, offset or root intrusion directly, so any excavation needed is one square metre of garden rather than a trench.
Reactive soil and shared supplies shape the fault
- Ground movement opens joints Shale and reactive clay beneath the older streets move with every wet and dry season, and buried supply runs shift with them until joints weep in places no inspection from above would ever find.
- One unit's leak is another's ceiling In the brick walk-ups between the station and the highway, shared supply runs and stacked wet areas mean a fault in one laundry often shows first as a stain two floors down, which is why we trace the whole run rather than the visible damage alone.
What a hidden leak looks like from outside
The climbing water bill
A bill that rises while your habits stay the same usually means water escaping where you cannot see it, often under a slab or along a buried run, and a simple meter test with every tap closed settles the question.
Stains that keep returning
A ceiling mark or paint bubble that dries and then returns points to an active supply rather than old damage, and in brick cottages moisture travels metres along the wall, so the stain and the source rarely share a room.
Water sounds at night
Hissing behind a wall or ticking under the floor when the house is quiet and nothing is running is escaping water announcing itself, and it is worth a call the same week because that sound is being measured on your next bill.
Why acting early matters
Water never takes a month off: whatever it escapes into, it keeps working while you sleep, which is why tracing a leak promptly protects far more than the pipe itself.
- Damage compounds quietly Water seeping through brick and timber softens subfloors, salts brickwork and feeds mould long before anything looks urgent, and the repair bill grows with every month the leak keeps its own schedule.
- Small faults stay small A pinhole caught early is a joint renewed, while the same pinhole after two wet seasons can mean a corroded run replaced from the meter, so prompt tracing is genuinely the economical path.
- Your records stay clean Undetected leaks undermine insurance claims and complicate sales, while a traced, repaired and documented job leaves certificates and a clear record that the problem was handled properly.
How it works
Our leak detection process, step by step
- 01
Call and tell us
Ring (02) 9072 0520 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
Trace and repair the source
Your plumber isolates the affected run carefully, pinpoints the escape with acoustic and thermal gear before opening anything, then seals or renews the faulty section with fittings matched to the pipe's era and pressure tests the whole line to prove the fix holds.
- 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 Carlton
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 Carlton 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.
Where we work
Where we work nearby
Leak detection reaches every street here and out through Allawah, Beverley Park, Kogarah Bay, Kogarah and South Hurstville, where housing of the same eras and materials means the detection gear and common repair parts are already stocked on the van.
Good questions, straight answers
What Carlton locals ask about hidden leaks
How do you find a leak behind a wall without opening it up?
Acoustic listening gear, moisture meters and thermal imaging narrow the escape to a small patch first, so any opening of tiles or plaster is a planned, targeted repair point rather than exploratory demolition.
What does leak detection cost?
The call out and assessment cost you nothing, and once the leak is traced you receive one fixed written price for the complete repair before any work begins, with no hourly charges.
Is a climbing water bill always a leak?
Not always, yet it is the classic hidden leak sign, and the meter test we run with every tap closed confirms within minutes whether water is escaping somewhere you cannot see.
Are the old pipes in local cottages more likely to leak?
Yes, because unrenovated Federation cottages here still carry galvanised supply lines corroding from within, and century-old clay drainage under reactive clay soil cracks and offsets, so we check both systems when tracing.
Can you detect leaks under concrete slabs?
We can, using acoustic correlation and pressure testing to pinpoint the faulty section beneath the slab, then we talk through repair options that avoid unnecessary excavation wherever the pipework allows it.
Do you repair the leak as well as find it?
Every job is find and fix, so the plumber who traced the escape completes the repair with parts matched to the existing pipework, all covered by our Lifetime Labour Warranty.
