A real person answers, day or night
The leak you can hear but never see
A meter spinning with every tap closed, or a damp smell with no visible source, means water is moving somewhere it should not. Ring (02) 9072 0520 and talk it through with a licensed plumber, and start the search on the right side of Asquith.
Pipework from three building booms
- Galvanised steel, the first generation Original supply lines corrode from the inside out, narrowing decade by decade until the weak point weeps behind a cavity wall.
- Post-war copper, the second Mid-century runs develop pinhole leaks at tired joints, hidden inside brick-veneer walls that were never meant to be opened.
- Everything since, the third Newer townhouse pipework fails differently, usually at flexi hoses and appliance connections rather than the pipe itself.
Even the suburb's best-known structure, the heritage-listed former Wrigley's factory with its landmark globe water tower, tells the same story: water infrastructure has always been part of this streetscape. Detection gear that finds a fault without demolition is not a luxury on these blocks, it is the only sensible way to work.
What detection involves
Leaks rarely announce themselves at the point where the damage shows, so the work is finding the true source. The full plumbing team here covers detection alongside every repair that follows, and the methods below are the ones that matter most on local housing stock.
Acoustic and pressure testing
Sensitive acoustic listening gear and isolated pressure testing track the exact point where a supply line loses water, ideal in brick-veneer and fibro cottages because walls and tiles stay untouched while we pinpoint and mark the fault before repairing it.
Thermal and moisture tracing
Thermal imaging and moisture meters map damp trails behind plaster and under floors, a careful approach for weatherboard homes where hidden leaks quietly rot timber framing before any stain ever reaches the paintwork, saving owners from far costlier structural repairs.
Buried line location
Ground microphones and line tracing locate leaks beneath driveways, garden beds and the sloping sandstone blocks around the ridge, meaning excavation digs one small hole at the exact marked position rather than opening a long trench across your whole garden.
Repair and reporting
Once a leak is confirmed we quote the fix in writing, repair with materials matched to the pipe's age, and hand over a detailed written report that insurers and strata managers actually accept, closing the whole job neatly without guesswork.
What the ridge does to buried pipes
Sitting roughly 183 metres up on the Pacific Highway ridge gives this patch of the Upper North Shore some of its nicest outlooks and some of its most stressed buried pipework.
- Ground movement Shale-and-rock terrain works joints loose over decades, and the roots from the heavy canopy follow the moisture those loosened joints release.
- Seasonal swing Cooler ridge-top winters push expansion and contraction through older lines all season, and gravity carries escaped water downhill into places you would never think to look.
Signs a leak is hiding
Most calls start with a symptom rather than a confirmed fault, and these three cover the majority of what arrives on the books.
Unexplained water bill spikes
A bill that climbs without any change in habits usually means water escaping somewhere invisible, and our testing finds the source before the next quarterly bill makes the damage even more expensive to prove and repair.
Damp patches and mould
Paint that bubbles, a wall that stays damp or mould regrowing after every clean all point to moisture sitting inside a cavity, which acoustic and thermal tracking locates precisely so repairs target the pipe rather than repainting blindly.
Hearing water when nothing runs
Water moving through walls or under floors with every tap turned off suggests a pressurised line has split somewhere, and because pressurised leaks worsen quickly we treat that call as urgent rather than routine, day or night.
Why waiting costs more
Catching a hidden leak early is the difference between a small repair bill and a renovation invoice, and these are the stakes in plain terms.
- Structural damage compounds quietly Water soaking subfloor timber, plaster and framing does its worst work in the weeks nobody is looking, and by the time a stain appears the repair has often grown from a fitting to a rebuild.
- Bills and insurance both punish delay A leak left running costs money every hour, and insurers increasingly want evidence of prompt action, which is exactly what a written detection report provides.
- Small leaks become emergencies A weeping joint today is a split line next month, and the difference between a planned fix and a burst pipe at midnight is usually just time, which is why a maintenance plumbing check catches these early.
How it works
The 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
Locate, then confirm
Your plumber runs the acoustic, pressure or thermal testing the symptoms call for, marks the exact leak position on the pipe run, and talks you through the repair options and reinstatement scope before quoting the fixed price.
- 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 Asquith
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 Asquith 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.
Every detection job also gets the whole-property view, and where the symptoms point below ground rather than through the walls, a CCTV drain inspection shows exactly what is happening inside the line.
Where we work
Where else we work
Detection work covers North Wahroonga, Hornsby, Mount Colah, Waitara and North Turramurra too, with the same testing kit travelling to each job, and a leaking line in a Mount Colah cottage gets the same careful treatment as any nearer address.
Good questions, straight answers
Leak questions Asquith locals ask
How do you find a hidden water leak?
We combine acoustic listening gear, isolated pressure testing and thermal imaging to pinpoint the leak's position first, so walls, tiles and floors only open where the fault is actually sitting.
What does leak detection cost?
The call out is $0 and every job carries a fixed written price before work starts, so you approve the full amount for finding and repairing the leak before anything begins.
Why do older homes here leak more often?
Many homes from the 1915 subdivision onward still carry galvanised and early copper supply lines, and age, ground movement on sandstone slopes and mature tree roots all shorten those pipes' working lives.
Who carries out the detection work?
Every attendance is by a fully licensed and insured plumber working under licence #275278C, never a subcontractor, and compliance paperwork for any repair follows with the invoice, as it should.
Is the repair covered afterwards?
Any repair we complete after locating a leak is protected by our Lifetime Labour Warranty, which means if the same fault ever returns we come back and make it right at no cost.
Can you detect leaks under slabs or gardens?
Yes, acoustic and tracing equipment locates leaks under concrete slabs, driveways and garden beds, including the root-affected lines common around treed ridge blocks, without excavating half your yard to find the problem.
