Leak Detection Nundah
A water bill that's crept up for no reason? Damp under the floor, mould along a skirting, or a musty smell that won't shift? Nundah's older Queenslanders run ageing galvanised-steel and copper pipework that springs hidden leaks in subfloors and wall cavities, while the newer slab units around Nundah Village hide leaks under the concrete. We track them down accurately — without tearing into your home to find them.
Leak Detection in Nundah — Find the Hidden Leak Without the Demolition
A water bill that won't settle, damp creeping up a wall, cracked tiles or a soft spot underfoot — in Nundah's character homes these usually mean a leak you can't see. Nundah is one of Brisbane's oldest settlements, and its pre-war and post-war timber-and-tin Queenslanders often run original galvanised-steel and copper pipework that corrodes from the inside out. The leaks tend to hide where the house can't show them: in the subfloor of a raised home, inside a wall cavity, or behind a fixed-in cabinet. Around Nundah Village and the Toombul corridor it's a different story — the newer slab-on-ground units and townhouses develop concealed slab leaks under the concrete instead.
TBP Plumbing Nundah finds the source with acoustic detectors, thermal imaging and pressure testing — no opening up heritage walls or lifting floors on guesswork. We show you exactly what we've found and quote the repair at a fixed price before any work starts.
We look after homes, strata complexes and businesses across Nundah, Wavell Heights, Banyo, Northgate, Clayfield, Toombul, Virginia, Ascot and the wider inner north.

Signs You May Have a Hidden Leak
A leak under a Queenslander floor or behind a wall rarely announces itself. These are the warning signs Nundah homeowners notice first — and the sooner you act, the less it costs to put right.
Higher than normal water bill
A bill that climbs while your household and habits stay the same is one of the clearest signs water is escaping somewhere you can't see — often a corroded line in an older home.
Damp walls or ceilings
Soft plasterboard, peeling paint, bubbling VJ walls or a stain spreading across a ceiling — with nothing obvious above — usually means a pipe is weeping inside the cavity.
Mould in unexpected places
Mould well away from the bathroom or kitchen — along skirtings, inside a wardrobe, or under a raised timber floor — points to constant moisture from a hidden leak feeding it.
Wet or soft patches outside
A patch of grass that's greener than the rest, boggy ground, or water pooling in dry weather along a side path can mean a buried supply line is leaking below the surface.
Sound of running water
A trickle or hiss inside a wall or beneath the floorboards when every tap and appliance is off is a strong sign of a leak in the pipework behind the scenes.
Water meter moving when idle
Turn off every tap and appliance, then watch the meter. If the dial keeps turning, water is escaping somewhere on the property — even when you can't see or hear it.

How We Find Leaks
Our whole approach is built around pinpointing the source first and disturbing your home as little as possible — no cutting into a heritage wall or lifting a floor until we know exactly where to look.
On-site assessment
We talk through what you've noticed, check the meter and usage, inspect the visible plumbing and the subfloor where we can, and narrow the leak down to a likely zone before any specialist gear comes out.
Locate with specialist equipment
Depending on the leak and where it's hiding — a subfloor line, a wall cavity, or under a unit slab — we use pressure testing, acoustic listening gear, thermal imaging or a CCTV camera to fix the exact spot without guesswork.
Clear report & repair plan
Once we've found it, we show you what's leaking, where, and your options for fixing it — with a fixed price quote before any repair work starts. No surprises and no pressure.
Detection Methods We Use
Method
Pressure testing
Best for
Confirming a leak is real and isolating which run of supply pipework has failed
Acoustic listening equipment
Tracing leaks in subfloor lines, buried pipes and under unit slabs by the sound of escaping water
Thermal imaging
Spotting moisture behind walls and ceilings through temperature variation — nothing opened up
CCTV pipe inspection
Eyes-on inspection inside drain and sewer lines to find cracks, failed joints or blockage points
Leak Detection Costs
We confirm costs before any significant investigation or repair work begins.
What leak detection costs comes down to where the leak is. A visible dripping tap or fixture is simple to diagnose and price on the spot. A concealed leak — in a subfloor, a wall cavity, under a unit slab, or in a buried supply line — takes more time and specialist equipment, and the cost reflects that.
For the trickier ones we start with an on-site assessment to confirm the likely source, choose the right detection method, and give you clear costs before we move ahead with any significant investigation or repair work.
In plenty of cases, once we've found the leak, we can carry out the repair on the same visit.
