A real person answers, day or night

The leak you cannot see is often the one that costs the most

A water bill that climbs for no reason, or a warm patch underfoot, usually means a pipe is weeping somewhere out of reach. Call (02) 9072 0502 and we will locate it precisely.

Where a hidden leak goes before you notice

Galvanised supply in the old cottages

The pre-war semis off Botany Road still run original galvanised water lines that corrode from the inside out. A pinhole can weep behind a wall for months, softening plaster and lifting paint long before the meter tells the story.

Concealed runs in the apartment slabs

In the towers around the station, supply pipes are cast into concrete and hidden above set ceilings. A slab leak there can migrate a full level down through the building before it ever surfaces as a stain on someone's plasterboard.

How we track a concealed leak

Every hidden leak leaves clues, so your plumber works from the meter inward with the right gear to fix a position before opening anything up:

Acoustic listening

Listening along the supply with acoustic sensors picks up the faint hiss of water escaping under pressure, which lets us fix the spot on a slab or behind a wall to within a small zone before a single tile ever comes off.

Pressure testing

Testing the line under controlled pressure shows whether the supply is losing water at all and roughly where, separating a genuine pipe failure from a dripping valve or a stop tap that somebody has quietly left half closed.

Thermal and camera

Scanning with thermal imaging and feeding a camera into the accessible runs reveals damp tracking through a slab or a cracked joint inside a wall cavity, so the diagnosis rests on what we can actually see rather than on a hunch.

Meter isolation

Isolating fixtures one at a time and watching the meter confirms whether water still moves with every tap shut, a plain check that proves a concealed leak really exists before anyone commits to lifting a floor or opening a wall.

Storm-season slab damp

On the filled former swampland the groundwater lies only a metre or two below the surface, so after heavy rain a real supply leak and rising groundwater can look alike until we test which one is wetting the slab, and a CCTV drain inspection rules the waste line in or out.

Older pockets off Gardeners Road

Around O'Riordan Street and Church Avenue the ageing galvanised runs fail most at their threaded joints, so a scatter of small pressure drops across a cottage points to pipework one weak joint away from a burst pipe.

Signs of a leak we get called about

The bill that jumped

A water bill that suddenly doubles with no change in how the household lives almost always means water is escaping somewhere unseen, and a meter test quickly confirms whether the loss sits on your side of the boundary.

The patch that stays warm

A stretch of floor or wall that feels warm or stays damp between uses often lies directly over a leaking hot line, and tracing it early spares the framing and the flooring the slow, steady soaking that otherwise follows.

The pressure that dropped

A broad drop in pressure through a period cottage frequently means corroding galvanised supply is furring up and weeping at once, and locating the worst run lets us renew only what has failed instead of the entire house.

Why finding a leak early pays off

A concealed leak wastes water every hour it runs and quietly damages the building around it, so tracing it precisely, among the more technical calls in our plumbing line, beats guessing every time:

Water damage compounds silently

A pinhole can soak a wall cavity for weeks before a stain appears, feeding mould and rot the whole time. Once the stain finally appears, the repair bill has usually multiplied several times over.

Precision saves your finishes

Knowing the exact spot means opening one tile or one section of ceiling, not a whole room on a guess. Accurate detection keeps a renovated shower recess or kitchen intact.

Insurers want proof

A documented location and cause supports a claim, so we report clearly on what failed and where. That paperwork often decides the outcome once the damage reaches your insurer.

How it works

Our step-by-step leak detection process

  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

    Pinpoint and repair

    Narrowing the search from the meter inward, your plumber marks the exact failure point, opens only that small section, renews the failed pipe or joint and retests the line under pressure to prove the loss has 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 Mascot

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 Mascot 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

Neighbouring suburbs on the same detection service

We trace leaks well past here as well, through Botany toward the bay, Rosebery, flat Eastlakes, riverside Wolli Creek and Tempe beside the canal, every job on one written quote.

Good questions, straight answers

Leak detection questions Mascot locals ask

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

We combine acoustic listening, pressure testing and thermal imaging to fix the position first, so we open one small area rather than excavating a slab on a guess.

My water bill jumped but I cannot see a leak anywhere, why?

A concealed supply leak often weeps inside a wall or slab for weeks before it stains anything, and a quick reading at the meter shows whether water is escaping unseen.

Can a leak in an apartment come from another floor?

It can, because supply runs cast into the slabs can carry water a level or two lower before it shows up as a ceiling stain elsewhere in the block.

Do the old cottages leak differently to the towers?

They do, since the pre-war cottages weep from corroded galvanised joints while the towers hide slab and riser leaks, so each needs a different tracing method.

Will I get a price before you open anything up?

Yes, once the leak is pinpointed you get a single written quote for the work, backed by the $0 call out fee, with no extras appearing later.

Do you provide a report for my insurer?

We can, documenting where the leak was, what failed and the damage found, which is often exactly the evidence an insurer asks for on a water claim.
