A real person answers, day or night
Two owners, two very different mystery leaks
One caller has a quarterly bill that doesn't add up, another a patch of ceiling that keeps returning after painting over it twice. Ring (02) 9072 0597 with either story.

Leak detection services we cover
Finding the exact origin of a leak, no matter which fixture, pipe run or floor of the building turns out to be responsible:
Slab and underground leak detection
A suspected slab leak gets narrowed to one small zone using electronic and pressure methods together, turning what could have been a full floor lift into a single targeted opening once the location is confirmed.
Hidden wall and ceiling leaks
A stain or soft patch tracks back through the cavity to its real source, telling a supply pipe fault apart from roof damage or failed waterproofing that only looks like the same problem.
Rising water account investigations
An unexplained jump in the quarterly bill is investigated in order, starting at the meter, moving fixture by fixture, until the responsible section is pinned down instead of guessed at.
Strata and common-property leak tracing
When a leak sits inside a unit block, testing establishes whether the fault belongs to your own pipework or a shared riser, giving owners and the strata manager one clear answer instead of a guessing game between two parties.
Reading a building's age before testing even starts
- A postwar cottage has usually been patched more than once Two or three generations of repair work can share the same roofline, so working out which run is genuinely live matters before any testing equipment gets switched on.
- Falling ground changes where escaped water ends up On streets stepping down from the ridge toward the water, a leak underground can travel well past its source before it ever reaches the surface.
- A younger townhouse near the centre hides faults in newer places Original build fittings tend to hold up, so a leak in a recent property more often traces back to a renovation rather than the original plumbing.
Common leak detection problems
The bill keeps rising and nobody can explain it
An account trending upward quarter after quarter, with no new appliance or extra household member to explain it, points at water leaving the system somewhere between the meter and the taps.
A patch stays damp no matter the season
Ground or flooring that never fully dries, whether it's midsummer or the middle of a dry spell, is being fed by something below the surface that a visual check alone won't find.
What an unresolved leak costs beyond the water itself
Ignoring a hidden leak rarely keeps things simple, and the longer it runs the more it touches:
- Structural timber softens well before paint or plaster shows it A stud or joist can be absorbing water for months while the wall in front of it still looks untouched.
- Every cycle it runs adds to the account A leak left unresolved across a couple of billing periods can turn an ordinary bill into a genuinely uncomfortable one.
- A pinhole caught early is a quick fitting swap Left to widen, that same fault can mean replacing a run of pipe and repairing everything the water travelled through on the way.
How it works
How a leak detection visit runs, start to finish
- 01
Call and tell us
Ring (02) 9072 0597 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
Traced and verified
Electronic and pressure methods combine to pinpoint the source, verified on the spot ahead of any opening, so whatever repair follows targets the actual fault rather than the general area around it.
- 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 Mona Vale
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 Mona Vale 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 testing points to a failed section of pipe rather than a pinhole, that becomes burst pipes work, and a drainage-side result routes straight to the drainage range. Everything else this crew covers sits on the plumbing page.
Where we work
Areas we service
This tracing service also covers Bayview, Warriewood, Newport, Ingleside and Elanora Heights, using the same equipment matched to whatever construction era and slope each property presents.
Good questions, straight answers
Leak detection questions from Mona Vale locals
My unit's water bill jumped but nothing inside looks wet. What now?
A rising account with no visible change usually means the loss sits in a wall, slab or riser, and acoustic listening equipment narrows that down before anyone talks about opening anything.
Could salt air actually be the reason a fitting started weeping?
Yes, corrosion pinholes an exposed brass or copper fitting from the outside in, and that failure point often shows up as a slow weep long before it becomes an obvious leak.
Whose responsibility is a leak inside a strata building here?
Anything inside your own walls is yours to fix, while a leak in a shared riser or common pipe is the strata's, and tracing the source properly is what settles which one it is.
Does an older house near the beach hide leaks differently to a newer townhouse?
Original copper on a house that's never been touched tends to fail at joints, while a newer townhouse leak more often traces to a fitting installed during a recent renovation.
Will you need to lift tiles or dig up the garden to find it?
Only once the equipment has already narrowed the search to a small, confirmed area, so any opening that follows targets one exact spot rather than a wide, hopeful search.
How do you tell a plumbing leak apart from a shower recess that was never sealed properly?
Pressure isolation rules the pipework in or out first, and if the supply and drainage both test clean, the fault almost always sits with waterproofing rather than a pipe.
