Bill up, no puddle?
Leak Detection
A leak you can’t see is the one that does the damage. We use acoustic and thermal detection to pinpoint a hidden leak before anyone starts cutting tiles or digging — so the repair is targeted, not exploratory. You get a fixed scope before we begin.

“Hot water died on a Sunday with three kids in the house. Mainline answered, gave me a 60-minute ETA, and had a new unit in by lunch. Knew the price before they started.”
“Burst pipe under the slab at 11pm. They talked me through the mains shut-off on the phone, turned up fast, and the quote was the quote — no surprises on the invoice.”
“Booked them to install a gas cooktop. Proper licence, compliance certificate handed over on the day. The first plumber who actually explained what I was paying for.”
Common questions
Leak Detection — answered.
How do you find a hidden leak without wrecking the house?
With acoustic listening gear, thermal imaging and pressure testing — we narrow it to a precise spot before any tile comes up or any slab is touched. The whole point is to repair a small targeted area, not go exploring.
What are the signs I’ve got a hidden leak?
A water bill that’s climbed for no reason, a warm patch on the floor (a hot-water line leaking under the slab), the water meter ticking over with every tap off, or an unexplained musty, damp smell. Any of those is worth a look before the damage spreads.
How much does leak detection cost?
We quote a fixed scope before we start, so you know the cost of locating the leak before any access work begins. Finding it precisely almost always saves money on the repair, because we’re not opening up the wrong area.
Can you detect a leak under a concrete slab?
Yes. Slab leaks are exactly what acoustic and thermal detection are for — we pinpoint the spot so the repair is a single targeted opening rather than lifting the whole floor.
Will my insurer want a leak-detection report?
Often, yes — a documented location and cause helps a claim. We provide a clear written report you can hand straight to your insurer.
