My water bill has spiked but I can't see any leaks. What should I do?

A sudden increase in your water bill is one of the most common signs of a hidden leak. The leak could be underground, under a slab, or inside a wall where you'd never see it. Call us and we'll use acoustic and thermal detection equipment to find the exact source without tearing anything apart.

Can you find leaks in pipes that run under my Alderley Queenslander?

Yes. Many Alderley Queenslanders have plumbing running through the subfloor space beneath the house. We use acoustic listening devices and thermal cameras to trace leaks in these pipes without pulling up floorboards or digging. If the pipes run under a concrete slab or pathway, we can detect through that as well.

How do I check if I have a water leak before calling a plumber?

Turn off every tap and water-using appliance in your home, then check your water meter. If the dial is still ticking over, water is escaping somewhere. You can also listen for hissing or running water sounds near walls and floors. If anything seems off, call us and we'll do a proper detection to find exactly where it is.

Can a small water leak cause serious damage if I leave it?

Yes. Even a slow drip can cause mould growth, timber rot, foundation movement, and thousands of dollars in wasted water over time. The longer a leak goes undetected, the more damage it does. Getting it found and fixed early saves you money and protects your property.

Do you fix the leak as well or just find it?

We do both. Once we locate the leak, we can repair it on the spot in most cases. Whether it's a burst pipe, corroded fitting, or failed joint, we carry the parts and equipment to get it sorted the same visit. You get one plumber, one visit, and the problem handled from start to finish.

How soon can you get to an Alderley property for leak detection?

We're through Alderley and nearby suburbs like Newmarket, Enoggera, and Grange daily. Most leak detection jobs can be booked within a day or two, and if you've got water actively leaking or a major spike on your bill, we'll prioritise getting to you as quickly as possible.

Water Leak Detection in Alderley

A hidden water leak in an Alderley home is a particular problem. These are older properties, many of them elevated Queenslanders built in the 1920s and 1930s, with subfloor spaces, wall cavities, and decades of renovation layered on top of original plumbing. By the time a leak shows up as a damp wall or a spike on your water bill, it's usually been running for a while. Our Alderley plumbers find exactly where it is without cutting through walls or lifting floors.

A lot of the galvanised and copper pipes in Alderley homes have been in the ground or behind walls for decades. Galvanised pipe corrodes from the inside out, slowly narrowing until it starts to pinhole and weep. You won't see it happening. The first sign is often a soft patch on a timber floor, a musty smell under the house, or a water meter that keeps ticking with everything turned off.

Methods We Use To Find Leaks In Your Alderley Property

We don't guess and we don't start cutting. Acoustic sensors pick up the sound of water escaping through a pipe under pressure. Thermal cameras show the temperature difference that moisture leaves behind in walls and subfloors. Moisture meters confirm exactly how far the water has travelled. Between the three, we can tell you the location before we touch a single wall.

Detection Methods

Our High Technology Leak Detection Equipment In Alderley

Acoustic Listening Devices

Water escaping under pressure makes a sound. We use sensitive microphones to pick it up through walls, under timber floors, and beneath concrete slabs. In older Alderley homes with subfloor cavities, this often finds the leak in minutes.
Thermal Imaging Cameras

Moisture changes the temperature of whatever it touches. Our infrared camera shows those changes on screen, so we can see a cold water leak tracking through a wall cavity or a hot water line bleeding heat under a floor.
Moisture Meters

Once we know where the moisture is sitting, we use meters to map how far it's spread through the timber and plaster. In a Queenslander that's been leaking for months, this tells us how much damage has already been done.
Pressure Testing

We isolate sections of pipe and watch what the pressure does. If it drops, water is getting out somewhere in that section. It's how we confirm a leak before we commit to any repair work.

Our Alderley Leak Detection Process

Initial Assessment

We discuss your concerns, check your water meter for movement when all taps are off, and visually inspect for obvious signs of leaks or water damage.
Detection Scanning

We systematically scan your property using acoustic listening equipment and thermal imaging to locate the leak source without invasive testing.
Pinpoint & Confirm

We use moisture meters and additional testing to confirm the exact leak location and assess the extent of any water damage to surrounding areas.
Repair Options

We explain what we found, provide repair options with upfront pricing, and can often fix the leak the same day with minimal disruption to your property.

Leak Types

Common Leaks We Find in Alderley Homes

Most leaks in Alderley follow a pattern. Older pipes, elevated homes, and decades of renovations create the same problems in different places. Here's where we find them most often.

Slab Leaks

If your water bill has crept up but nothing obvious has changed, a pipe under your slab is worth checking. These leaks run silently for months and can undermine the concrete before you know they're there. We pinpoint the exact spot so repairs are small and targeted.
In-Wall Leaks

Alderley's renovated Queenslanders often have copper or galvanised pipes running through walls that haven't been touched in 40 years. When they start to pinhole, the water tracks through the wall framing before it ever shows on the surface. Thermal imaging finds it without opening anything up.
Underground Water Main Leaks

A wet patch near the footpath or a garden that stays soggy after dry weather are classic signs of a leaking water main. On a property with an established garden, we locate the break accurately so you're only digging where you have to.

Warning Signs

Signs You May Have A Hidden Water Leak

Hidden leaks often show warning signs before causing major damage. If you notice any of these indicators, professional leak detection can find the source before problems escalate.

Unexplained High Water Bills

A sudden increase in your water bill without changes in usage often indicates a hidden leak. Even small leaks can waste significant water over a billing period.
Water Meter Running When Taps Off

If your water meter continues moving when all taps and appliances are off, water is escaping somewhere in your system. This is a clear sign of a leak.
Damp Or Discoloured Patches

Wet spots, water stains, or discolouration on walls, ceilings, or floors indicate water is reaching places it should not be. These patches may come and go.
Musty Smells

Persistent damp or musty odours often indicate hidden moisture and mould growth. This is common in wall cavities and under floors where leaks go unnoticed.
Warm Spots On Floors

Unexplained warm areas on floors, particularly over concrete slabs, may indicate a hot water pipe leak below. This is often the first sign of a slab leak.
Low Water Pressure

A gradual decrease in water pressure throughout your home may indicate a significant leak is reducing flow before water reaches your taps.

What Happens When a Leak Gets Left Too Long In Your Alderley Home

The longer a hidden leak runs, the more it costs to fix. Not just the plumbing, but everything the water touches along the way.

Your Water Bill Keeps Climbing

A slow leak that you can't see is still using water around the clock. By the time the bill arrives, you've already paid for hundreds of litres you never used. It won't improve on its own.

Timber and Foundations Take the Hit

In an elevated Alderley Queenslander, water finding its way into the subfloor or wall framing is a serious problem. Timber softens, stumps shift, and what started as a pinhole leak becomes a structural repair job. The longer it runs, the bigger the bill.

Mould Gets Into the Walls

Mould doesn't need much. A damp wall cavity or a wet subfloor space is enough. Once it establishes itself inside the structure of a home, getting rid of it properly is a serious job that costs a lot more than fixing the leak would have.

It Affects the Air You're Breathing

A home with ongoing moisture problems and mould growth isn't a healthy place to live. Dust mites, spores, and damp air aggravate asthma and allergies, especially in kids. Fixing the leak fixes the air quality too.

Why Alderley Homes Leak More Than You'd Expect

Alderley has some specific things working against its plumbing. These are the causes we come across most often when we're called out to a property in this suburb.

Ageing Galvanised Pipes

A lot of Alderley homes still have their original galvanised water pipes. From the outside they look fine. From the inside, they've been corroding for decades. Eventually the wall of the pipe gets thin enough to pinhole, and water starts tracking through the wall or subfloor long before anyone notices.

Flexi Hose Failures

The braided flexible hoses under your kitchen sink and behind your toilet have a use-by date that most people don't know about. When they fail, they fail fast, flooding a room in minutes. If yours are more than ten years old and have never been replaced, they're worth checking.

Soil Movement Near Kedron Brook

Properties on the lower side of Alderley, closer to Kedron Brook, sit on ground that swells and contracts with moisture levels. The 2022 floods shifted soil under a lot of homes in this area. That movement cracks underground pipe connections at the joints, often without any visible sign above ground.

Tree Root Intrusion

Alderley's leafy streets are one of the reasons people love living here. The mature trees along Banks Street and the older residential blocks near Grinstead Park send roots a long way in search of water. Underground water pipes at joints are exactly what they find.

Subfloor Pipes in Elevated Homes

Raised Queenslanders have water pipes running through open subfloor space that gets no attention for years at a time. Those pipes move with the house, corrode in the humidity, and sometimes get knocked during storage or pest inspections. By the time someone notices a problem, it's been dripping for a while.
