A real person answers, day or night
When a hidden leak runs for months with no puddle to follow
On the Botany sands the ground stays damp all year, so an escaping pipe soaks away unseen instead of pooling. Call (02) 9072 0592 and we locate it without tearing the place apart.
Why leaks hide so well under the flats
A permanently wet subsoil
Leaks inside shared walls
Rising bills before symptoms
Our leak detection services
Finding a concealed leak is about proving where it is before any wall opens, and across the slabs, risers and supply runs of the estate we work through it like this:
Acoustic listening
Using ground microphones and listening discs we amplify the hiss of water escaping under a slab or inside a wall cavity, walking the run until the sound peaks over the exact fault rather than opening the floor on a guess.
Pressure testing
By isolating a section and watching whether it holds pressure, we confirm the supply is leaking and roughly where, which matters most on the galvanised risers that corrode and weep from several points at once.
Thermal and moisture
Reading surface temperature and moisture through the walls and floor shows where warm or cool water tracks behind the finishes, so a vague damp area narrows to the single small spot worth opening up and repairing.
Camera and dye
Should the trail point at a drain or buried waste, we push a camera through and use dye to confirm exactly where the line has failed, so the repair lands on the real fault, not a hopeful dig.
Galvanised risers and ground that never dries
Corroding from both sides
One leak signals more
Testing beats digging
Common signs of a hidden leak
A climbing water bill
A water account that keeps rising while nothing looks wet is the classic hidden leak, usually a supply line weeping underground, and a metered test finds it so the water is stopped.
Warm patches on the floor
A section of floor that feels oddly warm underfoot often means a hot water line leaking within the slab, and thermal imaging pinpoints the run so we lift the smallest patch of concrete to reach it.
Damp in a shared wall
A stain creeping along a party wall between two flats usually traces to a buried riser weeping inside the masonry, and acoustic listening finds the exact joint so only that short length is exposed and renewed.
Why finding a leak early pays off
A concealed leak wastes water you are billed for and damages the building around it, so the sooner it is pinned down the smaller the repair and the damage stay:
Water you cannot see still costs
Damp undermines the structure
Precision saves your home
How it works
How leak detection works step by step
- 01
Call and tell us
Ring (02) 9072 0592 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
Pinpoint before we open
Rather than guess, we combine acoustic listening, pressure testing and thermal imaging until the readings agree on one spot, log it precisely, and confirm it so the only thing opened is the small area over the fault.
- 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 Hillsdale
Locating the fault this carefully is only worth it if the repair behind it is done to the same standard.
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 Hillsdale 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
Areas we service
We trace hidden leaks across Eastgardens, Matraville, Banksmeadow, Pagewood and Maroubra too, bringing the same acoustic and pressure gear to a slab weep in a Maroubra unit or a riser fault two suburbs over.
Good questions, straight answers
Leak detection questions from Hillsdale locals
How do you find a leak without digging up the floor?
We prove the leak with acoustic listening and a pressure test before touching anything, then open only the small patch of floor sitting directly over the fault rather than the whole slab.
My water bill jumped but I cannot see a leak. Why?
A hidden supply leak runs underground on your meter day and night, so the bill keeps climbing even though the taps all look dry, and a pressure test is the quickest way to confirm it.
Can you detect a leak inside a concrete slab?
Yes, warm or cool water moving through a slab shows up on thermal imaging and acoustic gear, letting us fix the run through the smallest area of concrete rather than lifting a whole floor.
Why do the old flats here leak inside the walls?
The galvanised risers inside the shared brick walls of the old estate blocks corrode after seventy years and weep into the masonry, which is why a damp stain shows before any pipe is visible.
What does a leak detection call cost?
You pay nothing for the call out, and once the leak is located we set a single fixed written price covering the find and the repair, agreed before we start.
Is the leak repair covered by a warranty?
Yes, both the detection work and the repair we carry out are backed by our Lifetime Labour Warranty, so a fault that resurfaces on the same line is ours to put right at no charge.
