Finding water where it should never be, without tearing your home apart
A hidden leak announces itself sideways: a meter creeping with everything switched off, a warm patch on a floor, a smell of damp with no stain to show for it. Ring (02) 9072 0504 and we will locate the source with proper gear, not guesswork.
Why peninsula pipes hide their leaks well
The housing stock here makes leak detection genuinely different from the standard suburban job:
- Original supply lines Cottages still awaiting their renovation turn often carry galvanised services from the suburb's earliest decades, corroding quietly underground where no stain ever shows on the plasterboard above.
- Double-brick and weatherboard construction Water in a brick cavity can travel a long way between the leak and the first visible damage, so the wet patch and the fault are rarely in the same room.
- Renovations over old plumbing Prestige rebuilds conceal pipework routes behind finished walls and stone, meaning even the owner often cannot say where a supply run actually goes.
Our leak detection services
Every locating method has its moment, so we bring the full kit rather than one trick:
Acoustic leak tracing
Acoustic listening gear picks up the hiss and trickle of pressurised water escaping inside walls or under slabs, and on old double-brick peninsula homes it means we can open one small access point rather than guessing across beautiful finished masonry.
Thermal imaging surveys
Thermal cameras read temperature differences along walls, floors and ceilings, showing warm or cool trails where water moves where it should not, which is particularly useful on renovated homes where the pipework's route is often anyone's guess from the outside.
Isolated pressure testing
Isolated pressure testing separates one plumbing zone from the rest of the house, so a slow pressure drop tells us whether the culprit sits on the hot line, the cold line or the long buried run toward the street.
Meter and isolation checks
Meter and isolation checks rule out the simple explanations first, confirming whether water is escaping inside your boundaries or beyond them, because a leaking Sydney Water connection and an internal fault look identical from the kitchen tap.

Common hidden leak problems we trace
Some presentations appear again and again around the local streets:
The meter that will not sit still
A meter turning while every fixture sits idle is the classic hidden leak signature, and because Victorian and Federation homes still carry corroding galvanised services, the escape often sits underground well before any stain appears on plasterboard.
Damp smells without a visible source
Damp smells and swollen skirtings on weatherboard cottages usually mean water travelling within wall cavities rather than a roof problem, and thermal imaging plus moisture readings find the path without stripping linings on a hunch.
Damp that shows downhill from the fault
Slope-driven escapes confuse everyone: waterfront blocks falling steeply to the bays can push escaping water metres downhill from the fault, so we trace the wettest point back up the run rather than digging where the damp shows.
Why leak detection matters here
- Water bills and water damage compound together A concealed escape runs twenty-four hours a day, and the repair cost never shrinks while the damage quietly spreads through cavities, skirtings and subfloors.
- Small leaks become burst pipes Corroded lines rarely fail politely; locating and renewing a weak run early beats an after-hours call when it lets go, which is exactly what our burst pipes team sees too often.
- A precise diagnosis protects your renovation Guesswork means exploratory demolition in expensive finished walls, while a located fault means one small, planned opening and a repair that lasts.
How it works
Our leak detection process
Four steps, in the open from the first phone call:
- 01
Call and tell us
Ring (02) 9072 0504 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
Locate, then price the repair
Your plumber confirms the leak's position with the appropriate gear, explains exactly what the repair involves, and hands you a fixed written price for locating and fixing it together, so nothing proceeds until you have seen the full plan in writing.
- 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 Longueville
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 Longueville 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 trace leaks around the peninsula
Our leak detection work covers every street from the wharf to the top of the ridge, plus Northwood, Riverview, Lane Cove, Woolwich and Greenwich, all within a short run, so a local van carrying the full locating kit reaches you quickly wherever the water is going.
Good questions, straight answers
Leak detection questions from Longueville locals
How do you find a leak hidden inside a wall?
We combine acoustic listening, thermal imaging and moisture readings to trace the escape to a single point, so the access opening is small and the repair is planned rather than exploratory.
Can you detect leaks in old galvanised pipes?
Yes, and much of the peninsula's earliest housing still runs corroded galvanised lines, so we listen along the known pipe routes and pressure test each section to find where corrosion has finally given way.
Will leak detection damage my walls or tiles?
In most cases no, because acoustic and thermal gear locates the fault externally, and if an access point is genuinely needed we cut the smallest possible opening and make good the area afterwards.
How much does leak detection cost?
You receive a single fixed written price before any work begins, the call out costs nothing, and the quote covers both the locating and the repair so there are no surprises later.
Do you repair the leak once you have found it?
Yes, your plumber carries certified fittings and common repair parts on the van, so most hidden leaks are traced and permanently repaired in the same visit rather than left for a second appointment.
How long does a leak detection visit take?
A straightforward detection usually finishes within a couple of hours, while leaks on long buried runs or steep bay-side blocks can take longer because the water travels well away from the fault. Beyond this page. Regular checks catch weak lines before they fail, so many locals fold this work into a maintenance plumbing visit. Elsewhere on the site. Where a leak involves the sewer side rather than supply, a CCTV drain inspection shows the pipe wall from inside, and the plumbing hub lists every internal service.
