A real person answers, day or night
The leak you cannot see is the one doing the damage
A pipe can weep inside a wall cavity or under a slab for months before anything shows, quietly rotting timber, feeding mould and inflating the water account the whole time. The full range of work behind a diagnosis like this sits at our plumbing services, and this page covers the detection half of it.
Water hides well on this ridge
The ground under the suburb makes guessing expensive, and that is exactly why proper detection matters here before anyone starts demolishing anything.
- Sandstone and shale, not forgiving soil The suburb sits on an elevated Hawkesbury sandstone ridge with shale through the mix, so a buried leak does not simply surface nearby. Water tracks along rock ledges and emerges metres from the source, which is why we locate before we excavate.
- Solid walls that trap moisture Double-brick and rendered construction holds damp inside the wall long before a stain appears, so by the time a patch shows on paintwork, the leak behind it has usually been running for months.
- New infrastructure, old services The Victoria Cross metro station opened in 2024 and reshaped the streets around it, but plenty of supply lines beneath the surrounding blocks predate every tower, and older pipes under new paving are a classic hidden-fault scenario.
How we find your leak
Every detection job starts with the same discipline: gather evidence, narrow the search, confirm the fault, and only then open anything up. We bring the full kit to every callout, because a guess costs more than the right instrument. Here is where each method earns its keep:
Thermal imaging scans
Thermal imaging scans walls and floors for the heat signature escaping water leaves behind, finding hot water line failures under tiles and inside cavities without breaking a surface, which suits the finished apartments and heritage rooms common throughout the suburb.
Acoustic leak tracing
Acoustic listening gear amplifies the hiss of pressurised water escaping a buried or concealed pipe, pinpointing the exact position along runs under concrete slabs, behind double brick and beneath the hard paved surfaces that dominate this ridgeline.
Pressure isolation testing
Pressure isolation testing sections off your supply one line at a time, watching which circuit drops and which holds, so a fault buried under a slab or shared inside a block gets narrowed down before any excavation or wall opening.
Moisture mapping and reports
Moisture mapping documents the full spread of damp through walls, skirtings and ceilings, separating an active leak from old staining, and the written report we produce supports the insurance claims and strata notices most owners and renters here eventually need.
The towers and the terraces tell different stories
Detection work here splits along the housing stock, and we carry the gear for both ends of it.
- Strata towers and stacked units In the high-rise and walk-up stock, a leak in one unit often announces itself in the ceiling below, so we work within building manager access rules, isolate the right riser or branch and document everything the owners corporation needs to see.
- Spring renovation season When the heritage terraces come up for their yearly renovations, walls open and floors lift, and freshly disturbed pipework is where hidden faults surface. We are regularly called mid-renovation to trace a leak a builder has found but cannot source.
- Commercial tenancies on the spine Along the office and retail core, a concealed leak in a tenancy fit-out can threaten stock, ceilings and the tenancy below, so we prioritise fast location and a written report the landlord and insurer can both act on.
Signs you have a leak hiding somewhere
These are the faults that bring us out most often, and each one has a tell worth knowing.
A water account that keeps climbing
A bill that climbs with no change in habits usually means water is escaping somewhere unseen, and at the last census most dwellings here were rented, so tenants and landlords both need proof of where the loss sits.
Damp patches that keep returning
A stain that grows on a ceiling or skirting after dry weather points to a concealed leak rather than condensation, and in the double-brick and rendered walls common around here moisture travels a long way from the source before showing.
Water where it should never be
Water surfacing on paving, a permanently damp garden bed in dry spells or a warm strip across a floor suggests a failed underground line, and the sandstone and shale ground makes guessing expensive, so precise location first protects the budget.
Why finding it early pays: the case for acting now
Acting on a suspected leak early is the difference between a repair and a renovation, and the case for it rests on three plain consequences:
- Damage compounds while you wait A weeping pipe inside a wall or under a slab never heals, and every week it runs it swells chipboard, stains plaster, feeds mould and undermines footings, turning a small repair into a rebuild.
- The account keeps climbing A leaking line can waste thousands of litres a month, and in a mostly rented suburb that cost lands on whoever holds the account, tenant or landlord, until someone locates and stops it.
- You fix the right pipe the first time Without proper detection, repairs become exploratory surgery, opening walls on hunches. Locating the fault precisely means one controlled opening, one repair, and no second visit to fix the guess you got wrong.
How it works
Our leak detection process, step by step
- 01
Call and tell us
Ring (02) 9072 0528 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 confirm
We run the full detection suite, thermal cameras, listening gear and line-by-line pressure decay testing, until the exact fault is confirmed by instrument or camera, then mark it, photograph the evidence and price the repair before anything is opened.
- 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 North Sydney
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 North Sydney 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.
From detection through to the repair itself, most jobs flow straight into burst pipes or a planned fix through maintenance plumbing, and where the escaping water turns out to be a drainage fault, our CCTV drain inspections take over from there.
Where we work
Areas we service
We cover the whole suburb and the streets immediately around it, including McMahons Point, Crows Nest, Cammeray, Neutral Bay and Waverton, bringing the same detection gear and fixed-price discipline to every job, whether it is a heritage terrace, a walk-up flat or a commercial tenancy.

Good questions, straight answers
Leak detection questions North Sydney locals ask
How do you find a leak without opening walls?
We combine thermal imaging, acoustic listening and pressure isolation testing to pinpoint the fault first, so only the small section of wall, floor or paving that truly needs opening gets touched.
What are the warning signs of a hidden leak?
Watch for a rising water account, damp or mouldy patches that return after dry weather, peeling paint, a warm floor strip, the sound of running water with every tap closed, or a meter moving while nothing is on.
Can you detect leaks in apartment buildings?
Yes, strata towers and walk-up blocks make up most of the housing here, so we coordinate building manager access, isolate the correct riser and produce the written reports owners corporations and insurers usually ask for.
How much does leak detection cost?
The call out and assessment cost nothing, and once we have located the leak you receive a single fixed written price covering the detection work and the repair, before any tool comes off the van.
Will my insurance cover a hidden leak?
Most policies cover sudden hidden water damage and the cost of accessing the pipe, and we supply a written location report with photographs that supports your claim from the first phone call to the insurer.
Do you repair the leak as well as find it?
We do, because finding it is only half the job, so once the fault is confirmed we quote the complete fix in writing, complete the repair and back the workmanship with our Lifetime Labour Warranty.
