Leak Detection Sandgate
Unexplained water bills? Damp patches on walls, mould in the wrong places, or soft patches in the lawn? Many Sandgate homes are on ageing galvanised or copper pipework — and the salt air and sandy coastal soils accelerate corrosion and movement in underground supply lines. We find hidden leaks accurately — without unnecessary cutting or digging.
Leak Detection in Sandgate — Galvanised Pipes, Salt Air, and Heritage Homes
Sandgate and Shorncliffe's older homes present a specific leak detection challenge. Galvanised steel water lines fitted in the 1930s to 1950s corrode from the inside out — the first sign is often a spike in the water bill or a patch of unusually green lawn. Salt air from the bay accelerates external corrosion on exposed fittings and connections. In homes on stumps, under-floor supply lines can also develop slow drips that go unnoticed for years before the damage becomes visible inside. TBP Plumber Sandgate uses acoustic detection, thermal imaging, and pressure testing to find the exact source before any repair work begins.
TBP Plumber Sandgate uses acoustic detectors, thermal imaging, and pressure testing to locate leaks precisely — without opening walls or digging unnecessarily. We find the exact source, show you what we've found, and quote the repair with a fixed price before we start any work.
We serve residential and commercial properties across Sandgate, Shorncliffe, Brighton, Bracken Ridge, Taigum, Zillmere, Deagon, Boondall, and the wider Brisbane City Council area.

Signs You May Have a Hidden Leak
Leaks aren't always obvious. These are the most common warning signs — and the earlier you act, the less damage and cost involved.
Higher than normal water bill
An unexplained increase in your water bill — with no obvious change in usage — is one of the clearest signs water is escaping somewhere in your system.
Damp walls or ceilings
Patches of damp, soft plasterboard, peeling paint, or water stains on walls or ceilings with no obvious cause above often indicate a hidden pipe leak behind the surface.
Mould in unexpected places
Mould appearing in areas away from bathrooms and kitchens — particularly on internal walls, under floors, or in wardrobes — suggests persistent moisture from a hidden leak nearby.
Wet or soft patches in the lawn
Patches of unusually green or lush grass, soft or boggy ground, or water pooling in dry weather can indicate an underground pipe leak below the surface.
Sound of running water
If you can hear water running, trickling, or hissing inside walls or under floors when all taps and appliances are turned off, there's likely a leak in your pipework.
Water meter moving when idle
Turn off all water in your home and check the meter. If it's still ticking or the dial is moving, water is escaping somewhere in your system — even if you can't see or hear it.

Early detection keeps repair costs down and prevents structural damage. Call us for an on-site assessment.
How We Find Leaks
Our approach is focused on finding the exact source with minimum disruption — avoiding unnecessary cutting or digging before we know precisely where the problem is.
On-site assessment
We review your symptoms, check water usage patterns, inspect visible plumbing, and isolate the likely zone — narrowing down where the leak is before any specialist equipment is deployed.
Locate with specialist equipment
Depending on the leak type and location, we use pressure testing, acoustic listening equipment, thermal detection, or CCTV pipe inspection to pinpoint the exact source without guesswork.
Clear report & repair plan
Once found, we explain exactly what we've located, where it is, and what repair options are available — with a fixed-price quote before any repair work begins. No surprises.
Detection Methods We Use
Method
Pressure testing
Best for
Confirming a leak exists and isolating which section of pipework is affected
Acoustic listening equipment
Locating leaks in underground pipes and under slabs by detecting sound of escaping water
Thermal imaging
Identifying moisture behind walls and ceilings through temperature variation — no cutting required
CCTV pipe inspection
Visual inspection of drain and sewer lines to identify cracks, joint failures, or blockage points
Leak Detection Costs
We confirm costs before any significant investigation or repair work begins.
Leak detection costs depend on the type and location of the leak. A visible leaking tap or fixture is usually simple to diagnose and price on the spot. A hidden leak in a wall, under a slab, or in an underground pipe requires more time and specialist equipment — and the cost reflects that.
For more complex situations, we start with an on-site assessment to confirm the likely source, decide on the best detection method, and provide clear costs before moving ahead with any significant investigation or repair work.
In many cases, once the leak is found, the repair can be completed in the same visit.
