Chasing the Leak You Cannot See

When the bill creeps up, a musty smell lingers, or render stays damp in one spot, water is escaping where you cannot see. Ring (02) 9072 0502 and we will pin down exactly where.

What Makes a Hidden Leak Hard to Find

Two features of the local housing turn a simple leak into a genuine hunt.

Galvanised pipe corroding out of sight

The pre-1940 cottages used galvanised steel that rusts from the inside, so pinhole weeps open at joints buried in wall cavities where nothing shows for months.

Slabs sitting on shifting clay

Reactive clay swells and shrinks with each wet and dry spell, stressing supply lines under later slab additions until a joint parts and water tracks beneath the concrete.

Long runs under period floors

Timber-floored homes on Harrow Road hide long supply runs under the boards, where a slow drip feeds the bearers and joists before anyone notices a soft spot.

How We Detect Hidden Leaks

Detection means narrowing the search, then confirming the exact point before any tile or slab is touched:

Acoustic Leak Tracing

Using ground microphones and listening discs, we follow the faint hiss a pressurised leak gives off as it escapes, working along the buried run until the sound peaks above one point, which reveals the break far more reliably than any guess or educated hunch.

Pressure Testing

By sealing off the supply and watching how fast it bleeds down, we confirm a leak is genuinely present and gauge its rough scale, then shut branches one by one until the loss narrows to the single length of pipe truly at fault.

Under-Slab Leak Location

Where water is escaping below concrete, we layer acoustic readings over pressure-drop figures and the thermal signature of a warm line to fix its position tightly, so any cut through the slab lands squarely on the break rather than probing about in hope.

Meter and Supply Checks

Watching the meter dial creep with every outlet closed tells us at once that water is moving when nothing should be, and we then test the incoming service, the internal branches and any garden line apart to separate a true leak from a weeping tap.

Leaks Behind the Older Streets

How a leak behaves depends on when and how the home was built.

Cottages near Seaforth Park

In the Federation and interwar homes, decades-old galvanised and copper joints are the usual offenders, and finding the one weeping fitting among many is where detection earns its keep.

Later slab additions

Rear extensions and second bathrooms poured onto reactive clay put supply lines under concrete, and when the ground moves those runs fail first, so we expect movement.

Common Leak Problems We Trace

The situations that most often bring us out to hunt a leak:

The Runaway Water Bill

A bill that climbs while the household uses no more than usual usually means something is running out of sight, and checking the meter after dark with every tap shut confirms it before more litres are lost.

The Soft Spot in the Floor

A patch of flooring that flexes or a skirting that stays damp is often fed by a line weeping under the boards or slab, and locating it early spares the bearers, joists and footings from rot.

The Warm Line Underfoot

An unexplained warm strip across a tiled floor usually traces to a hot water line leaking beneath the slab, so pinpointing the run means we lift only a small area of tile, not chase it across the room.

Why Early Leak Detection Matters

A concealed leak is never static, so acting early is the difference between a small repair and a structural one:

Footings and slabs stay stable

Water pooling under a slab on reactive clay accelerates the ground movement that cracks it, so stopping the leak protects the footings before the damage spreads.

Repairs stay small and targeted

Precise location means we open one square of wall or floor, not a whole room, so the disturbance and making good stay minor.

The waste on the bill stops

A hidden leak runs day and night whether you are home or not, so sealing it settles a bill that has quietly been climbing.

How it works

Our Leak Detection Process, Step by Step

  1. 01

    Call and tell us

    Ring (02) 9072 0502 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.

  2. 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.

  3. 03

    Locate then repair

    With the leak pinpointed on the day, we show you exactly where it sits, agree the fix, then open only that spot to renew the failed pipe or joint and pressure test the run again to confirm the escape has genuinely stopped.

  4. 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 Bexley

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 Bexley 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.

Reading where water hides in a century-old home is a skill built on the ground, not from a manual.

Where we work

Areas We Service

Our leak specialists range beyond the suburb into Bexley North, Rockdale, Kingsgrove, Arncliffe and Banksia, tracing the hidden leaks that trouble the older homes there, always on one upfront price with nothing charged simply to attend.

Good questions, straight answers

Leak Detection Questions Bexley Locals Ask

How do you find a leak without digging up the whole house?

We shut off and pressure test the system section by section, then listen along the run with acoustic gear to pinpoint the exact spot before anything is opened.

My water bill jumped but I cannot see a leak. Why?

A hidden leak inside a wall cavity or under the slab can run unnoticed for months, and in older homes a corroding galvanised joint is a very common culprit.

Can you locate a leak underneath a concrete slab?

Yes, we read acoustic signals, pressure loss and thermal clues together to fix an under-slab leak in place, so any cut is kept to the small patch directly above it.

How quickly can you come and find a suspected leak?

A licensed plumber answers day or night, and most leak searches are scheduled for the same day, since a leak left to run only weakens footings and framing further.

Does the leak investigation cost anything up front?

The call out costs $0 and the whole job goes on paper up front, so having the leak located and the repair quoted is done at no charge to you.

Is the repair after detection guaranteed?

The repair we make after finding the leak sits under our Lifetime Labour Warranty, so should that section ever weep again, we come back and sort it free of charge.
