A real person answers, day or night
A hidden leak wastes water and structure at the same time
Call (02) 9072 0504 and describe what you are seeing, whether it is a spreading stain, a bill that keeps climbing or damp that never dries. A licensed plumber will talk through the likely culprits and book a detection visit that finds the truth before anything gets opened up.
What leak detection looks like on this plateau
The houses built across the 1940s to 1960s boom here still carry much of their original supply pipework, copper in the better cases and early galvanised where nothing has been upgraded. Sixty-plus years of service shows at fittings long before it shows on a ceiling.
- Shallow shale sitting over reactive clay swells and shrinks through every wet and dry season, working joints constantly even when nobody touches them
- Water follows the easiest path through framing and cavities before it ever stains plaster, so the leak is rarely where the damage appears
- Detection here is an instrument job, not an exploratory one, because guessing means opening walls plastered over half a century ago
Core leak detection services, done properly
Supply tracing, pressure testing, underground locating and moisture mapping: the four capabilities below handle the great majority of concealed leak callouts across the suburb's post-war homes. Each one proves where the water goes before committing to a repair, and the full range sits on our plumbing hub.
Acoustic and thermal tracing
Acoustic listening gear and thermal moisture mapping trace a hidden leak to the exact failing joint behind brick veneer or under a slab, so the repair opens one small, deliberate access point instead of demolishing a wall on a guess.
Pressure drop testing
Isolating sections of pipework and running a pressure drop test confirms whether a loss is genuinely real, separates supply faults from drainage faults, and gives you proof of the problem before anyone lifts a floorboard or drills into decades-old brickwork.
Underground leak locating
For suspected underground leaks along the long block-front supply runs, tracer gas and electronic line locating pinpoint the escape position on the pipe rather than digging exploratory trenches across a garden that has taken a good fifty years to establish.
Documented findings
Every detection job finishes with a written report recording where the leak sits, how it was confirmed and what the repair involves. Insurers and Sydney Water both accept that documentation when a concealed leak claim needs supporting evidence on file.
Why water here travels further than you think
The blocks along the plateau edges fall away steeply toward Berowra Creek and the gorge, and water obeys gravity without argument. A supply leak on the high side of a battle-axe block can travel metres through soil and framing before it surfaces downhill.
- The damp patch you can see often sits nowhere near the pipe that caused it, surfacing instead at a low-side garden bed, a retaining wall or the footings below
- Homes backing onto the bushland valley cop the same effect from slope-side moisture, where surface damp and a genuine pipe leak get confused for one another
- Instrument-led detection ends that confusion, and it also separates clean supply faults from drainage issues that need the CCTV drain inspection camera instead
Common hidden leak problems we diagnose
The bill that climbs without a drip
A water bill that climbs without any visible drip usually points to a concealed supply leak under the house or in a wall, and because the pipework here is original copper from the fifties and sixties, fittings fail quietly.
Stains far from any wet area
A ceiling stain appearing rooms away from any bathroom or the laundry means water is travelling along a framing member or pipe run before it shows, which is precisely the situation acoustic detection was built to resolve.
Leaks that follow the seasons
Ground movement through reactive clay stresses joints on older supply and drainage runs alike, so a leak appearing after a wet winter often traces to a pipe that has shifted rather than one that has split.
Why finding it properly matters: three reasons to act
Water destroys quietly. A weeping joint inside a wall cavity saturates framing, insulation and plaster long before the stain appears, and by the time damage is visible the repair has grown from a pipe fitting into carpentry as well.
Every litre is billed. A concealed supply leak runs around the clock whether you are home or not, and on a metered connection that loss lands on your quarterly bill month after month until the pipe is actually fixed.
Certainty beats demolition. Detection before repair means one access point instead of three holes in the wrong walls, and a documented diagnosis also protects your position if the damage ends up as part of an insurance claim.

How it works
Our leak detection process, step by step
- 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, repair and prove it
With the fault confirmed, we mark the exact position, open the smallest access the repair allows, fix the pipe or joint with materials matched to the home's era, and pressure test the line before closing anything up.
- 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 Hornsby Heights
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 Hornsby Heights 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.

Good questions, straight answers
Leak detection questions Hornsby Heights locals ask
How do you find a leak without breaking into walls?
We combine acoustic listening equipment, thermal moisture mapping and pressure testing to pinpoint the exact failing point first, so any access opening we make is small, deliberate and in the right place the first time.
What does leak detection cost?
The call out and assessment cost nothing, and once we have confirmed the fault you receive one fixed written price for the detection and repair before any work begins, with nothing added afterwards.
How long does a leak detection visit take?
Most detections are resolved within a single visit, though genuinely complex concealed leaks under long supply runs can take longer, and we tell you honestly on the phone what to expect before we arrive.
Why do older homes here develop hidden leaks?
The post-war housing stock still runs much of its original copper and galvanised pipework, and decades of movement in reactive clay soils stress joints until they weep inside walls and under floors.
Can a leak be repaired on the same visit?
Usually yes, because our vans carry the common fittings for the era of pipework in this area, and once the leak is located we scope the repair and proceed once you approve the fixed price.
Is a hidden water leak an emergency?
A concealed leak becomes urgent when it is flooding, staining ceilings or pooling near floor-level light fittings, and our emergency plumbing team handles those after-hours situations, while slower weeps are best booked as planned work.
