A real person answers, day or night
The leak you hear but never see
A hidden leak rarely announces itself with a puddle. It shows up as a water bill creeping upward, a musty corner that never quite dries, or a faint hiss behind brick while every tap sits closed. Gordon homes hide their plumbing well, which is exactly why finding the leak matters more than guessing at it.
Why local houses hide their leaks so well
- Federation and mid-century pipework The weatherboard and double-brick homes on the leafy streets toward the Stony Creek valley often run their original supply lines, and decades of corrosion inside those runs eventually weeps into wall cavities and subfloors.
- Brick skins that mask moisture Solid brick and brick-veneer walls absorb and spread damp, so a leak that started months ago only shows on the surface long after the damage underneath has grown.
- Reactive clay and shifting ground The suburb's shale and reactive clay soils move with the seasons, stressing buried supply runs and older joints until slow leaks develop where the pipework was never designed to flex.
Core leak detection services: what we find and how
Our leak detection covers the full supply side of the property, from the water meter to the last fixture, using acoustic listening gear, thermal imaging and pressure testing to pinpoint faults without tearing the house apart.
- Concealed wall and slab leaks Thermal imaging and acoustic correlation narrow a hidden fault to a single spot, so the opening in a wall or slab is made once, at the leak, not exploratorily across half a room.
- Underground supply line leaks Pressurised mains between the meter and the house are isolated and tested section by section, and because tree roots and shifting clay are common around here, we dig only where the evidence points.
- Hot water and fixture leaks Slow weeps from cylinders, tempering valves and buried fittings are traced and repaired, and a tank that is quietly losing water often needs attention before it becomes a burst pipes call instead.
- Meter and pressure testing We isolate the property at the meter and watch the dial, separating a genuine household leak from a supply-side issue, then hand you the evidence before any repair is quoted.
Slab country on the station side
- A different kind of leak Walk from the village retail strip toward the heritage railway station and the housing mix changes character: newer apartment blocks and renovated ground-floor commercial tenancies sit on concrete slabs along that corridor.
- No crawlspace to listen under Slab pipework is buried in the pour, so the first sign is often a warm patch on tile or a carpet edge that never dries rather than a damp floorboard.
- Thermal imaging earns its keep here It maps the heated run through the slab before a single square of tile is lifted, which keeps the repair small and the disruption contained.
The problems that bring locals to call
A water bill that climbs without explanation
A meter spinning with every tap closed almost always means water is escaping somewhere on the property, and finding it early costs a fraction of the quarterly bill it quietly generates.
Damp patches and mould that return
Plaster that blisters or paint that flakes in the same spot, especially through the cool damp ridge winters, points to moisture feeding it from behind, and cleaning the surface never fixes the source.
The sound of water with nothing running
Hissing behind a bathroom wall or under a floor while the house sits silent is the clearest signal there is, and it deserves a proper diagnosis rather than a wait-and-see.

How it works
How the job runs, 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 and confirm the leak
Acoustic listening gear and thermal imaging narrow the fault to a single point, pressure testing confirms the diagnosis, and you see the evidence before any wall, slab or trench is opened, so the repair stays as small as the leak itself.
- 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 Gordon
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 Gordon 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 diagnosis to repair, the full range of general plumbing work sits on our plumbing hub, and where a leak turns out to be drainage-side rather than supply-side, our CCTV drain inspections find that too.
Where we work
Areas we service
Leak detection runs across the suburb and the surrounding Ku-ring-gai area, taking in Killara, Pymble, West Pymble, St Ives and Roseville, with the same acoustic and thermal equipment carried on every van, so a concealed leak in any of those suburbs gets the same pinpoint diagnosis and the same fixed written price before a repair begins.
Good questions, straight answers
Questions Gordon locals ask about hidden leaks
How do you find a leak hidden inside a wall?
- We combine acoustic listening gear with thermal imaging to narrow the location, then confirm with moisture readings, so opening the wall happens once, at the exact spot the leak sits.
What are the warning signs of a concealed leak?
- Watch for damp plaster, musty smells, mould returning after cleaning, a creeping water bill, or the sound of running water with every tap turned off, and call us to investigate.
Do older homes around here leak more often?
- Yes, because pre-1940 houses in this area run their original supply pipework behind double-brick and weatherboard walls, and decades of movement and corrosion eventually show up as concealed leaks.
Will my water bill drop after a leak is fixed?
- Usually, yes, because a hidden leak can waste thousands of litres quietly, and once the run is repaired the meter stops ticking over for water you never actually used.
Can you check whether a leak is mine or Sydney Water's?
- We can, by isolating the supply at the water meter and watching it, then tracing the household side, and we will tell you honestly which side the fault belongs to.
How long does leak detection take?
- Most residential jobs are diagnosed within a single visit, because the acoustic and thermal equipment narrows the location quickly, and we quote the repair separately once the fault is confirmed.
