The first method doesn't find it, and the person holding one tool has nothing else to try.
Acoustic listening is excellent on pressurised supply. It hears nothing at all on a waste pipe, because there's no pressure to make a sound. Thermal imaging maps a wet area beautifully and can't tell you which of three pipes in that wall is leaking. Moisture meters find the wettest point and say nothing about why it's wet.
Every one of these is genuinely good equipment. Every one of them has a blind spot — and if that blind spot happens to be your leak, the visit ends with "we couldn't locate it," a bill, and a suggestion to open up and have a look.
The methods aren't competitors. They're a sequence.
Acoustic rules a supply leak in or out. Thermal defines the wet area's boundary. Moisture mapping finds its wettest point. Tracer gas confirms an exact position where the others can't reach.
We carry all of them, and we work through them until the answer is a point rather than an area.

Knowing the blind spots is the whole argument for carrying more than one.
Establishes whether a leak exists and roughly where — inside, outside, or on the incoming supply. Free, fast, and correctly the first step.
Narrows from a building to a run by isolating sections individually.
Escaping pressurised water makes a characteristic sound carrying through pipe, structure, and ground. Highly effective and frequently the whole answer.
Reads surface temperature differences, mapping the extent of a wet area. Excellent on hot supply and heating leaks.
Measures actual moisture content in materials and finds the wettest point — which sits nearest the source.
Running each fixture individually while watching the damp respond. The method that works on waste leaks, where acoustic is useless.
A safe gas mixture in a drained line escapes at the fault and rises to a detector. The method for plastic pipe, very small leaks, and deep or noisy environments.
For drainage — cracks, open joints, displaced sections.
Each one rules something in or out, and the combination produces a position precise enough to justify one cut.
Every one of these narrows it before we arrive.
Close every tap and appliance. Nothing filling, no toilets flushed.
Read your water meter, including the fine dial. Leave it one to two hours. Read it again.
A pressurised supply leak, running continuously right now — and acoustic becomes the lead method.
Your supply is tight, and it's waste or heating — which means acoustic is off the table and controlled testing or tracer gas leads instead.
Watch the damp through a normal day. Darker after a shower, after the washing machine empties, after a particular toilet?
Waste — and the fixture that triggers it identifies the branch.
Pressurised supply.
Check the gauge.
Needing topping up over days means the heating circuit is losing water — a third system, with thermal imaging as the strongest tool.
Close the main and repeat the meter test.
The leak is between meter and shutoff — usually underground, and acoustic ground microphones lead.
Condensation, a failed roof, blocked guttering, penetrating damp, and rising damp all present as an internal damp patch. Establishing whether it's plumbing is part of the job — and if it isn't, we'll tell you and stop.
The rule that makes the sequence worth working through: water emerges where the building lets it, not where it failed.
It leaves the fault, runs along the top of a joist, follows a pipe through a wall, crosses a floor void, and comes through wherever gravity and construction allow. The visible damage can sit rooms from the actual failure.
Which is why cutting into visible damage is how people pay for a hole in the ceiling and still have a leak running.
Every wrong opening is a cost you keep, and a wrong guess narrows nothing.
Detection inverts that — the location is established first, and the opening is one deliberate cut at a known point.
Supply lines in or beneath the slab. Acoustic through the floor, confirmed with tracer gas where the sound doesn't carry.
Meter test identifies it; ground microphones locate it.
Water travels down the outside of the pipe, emerging a storey below. Thermal maps the extent; acoustic pinpoints on supply.
Running along joists until something stops it. Moisture mapping finds the wettest point.
Failed tray seals, waste connections, and grout no longer shedding water. Extremely common — and a waste leak, so acoustic won't touch it.
Pan seals passing a small volume with every use.
Because the water is genuinely hot.
Until the cabinet gives it away.
Made once, covered, never looked at again.
Which is also the case against a detection visit that ends inconclusively. A week spent arranging a second attempt with different equipment is a week the structure keeps absorbing.
Acoustic, thermal, moisture, tracer gas, dye, and camera — because each has a blind spot, and one of them might be your leak.
Each method rules something in or out. The combination produces a point rather than an area.
That answer usually means one tool ran out of road, not that the leak is unfindable.
Supply, waste, or heating decides which methods even apply — and searching the wrong one thoroughly finds nothing.
Meter, use-pattern, heating pressure. Every result you bring us shortens the sequence.
Condensation, roofing, and penetrating damp all imitate a leak. If that's what we find, we stop and say so.

Thermal can't separate adjacent pipes. Each tool has a blind spot, and the answer is working through the others rather than opening the wall and hoping.
Because they're a sequence, not alternatives. Acoustic rules a supply leak in or out, thermal defines the wet area, moisture mapping finds its wettest point, and tracer gas confirms a position where the others can't reach. The combination produces a point; any one alone frequently produces an area.
Close everything, read the meter, wait one to two hours without using water, read again. If it moved, water is leaving your system. Free, and it decides which method leads.
By whether it changes. Supply is pressurised so it leaks constantly — the damp is unchanging whether the property is busy or empty. Waste only leaks when something is used. Watch it for a day and tell us; it eliminates a whole set of methods.
Frequently not. Water runs along joists and pipe runs before it drops, so the fault can sit metres away. The stain marks where it emerged.
One of the most reliable indicators of a concealed or underground supply leak. Buried leaks run for months on the bill alone, and every litre is metered.
A safe gas mixture introduced into a drained pipe, escaping at the fault and rising through the structure to a detector. It's what works where acoustic struggles — plastic pipe, very small leaks, deep or noisy environments.
That's a leak on the closed heating circuit rather than your water supply. Thermal imaging is at its strongest here, because the water is genuinely hot — a different system needing a different lead method.
That's the point of the sequence. The methods locate the fault so access, when needed, is one deliberate opening at a known position rather than exploratory cutting.
It could, and that's a real part of the diagnosis. Condensation dries and stays dry; a leak returns. If it isn't plumbing, we stop and say so.
Often a hot supply or heating line leaking beneath. Distinctive, and worth acting on quickly — sub-floor leaks saturate a wide area before surfacing.
Frequently a couple of hours where the leak is narrowed quickly. Longer where the sequence has to run further. The free tests you do beforehand genuinely shorten it.
Acoustic can't hear a waste leak. Thermal can't separate two pipes in a wall. Moisture meters can't tell plumbing from condensation. Every one of these is good equipment with a blind spot — and a detection visit that ends in "we couldn't locate it" usually means one tool met its limit and there was nothing else to reach for.
