A warm floor is a leak telling you where it is

Most hidden leaks are unhelpful. They surface somewhere other than where they started, or they never surface at all and the only clue is a bill. There is one exception, and on slab-on-ground housing it is worth knowing about.

If a hot water line running within or beneath the slab starts leaking, the water is heated and the concrete conducts. The warmth reaches the surface, and you get a patch of floor that is noticeably warmer than the rest. Bare feet in the morning is how most people find it.

That is unusually generous, because it points at the location rather than merely announcing that something is wrong. The supporting signs are worth knowing too: a sound of running water with every tap closed, a hot water system cycling more than it used to, and a bill that has risen with nothing visibly wet anywhere.

None of that means concrete has to come up. It means it gets located precisely first, with acoustic listening, pressure testing on the hot and cold lines separately, and thermal imaging. Only then is it worth discussing whether the answer is opening one small area or abandoning that run and re-routing it.

Local leak guide

Leaks in a Seven Hills home

The slab conducts heat

A leaking hot water line under concrete warms the floor above it.

It is one of the few faults that points at its own location.

Running water with the taps closed

A sound that should not be there is a real symptom, not imagination.

Worth listening for at night when the house is quiet.

The system cycling more than it used to

Hot water being lost is hot water being reheated.

That shows up as the unit working harder for no apparent reason.

Opening the slab is a last option

Not a first one, and never before the leak has been located precisely.

Re-routing the affected run is sometimes the better answer entirely.

A creeping meter is the fallback test

Everything off, and a moving dial means water is genuinely leaving.

Under a slab it can do that for a long time without surfacing.

What leak work costs in Seven Hills

Fixed price agreed before anything starts. These are indicative 2026 ranges.

Emergency isolation and make-safe $200 – $450

Water stopped and the situation stabilised, at any hour.

Locate a slab leak $350 – $700

Acoustic, pressure and thermal, with nothing cut into concrete to find it.

Locate a concealed leak $250 – $600

The same approach, for a leak that is not under the slab.

Burst pipe repair $300 – $900

Depending on the pipe, the material and how it has to be reached.

Re-route an affected run quoted

Where abandoning the line under the slab is the better answer than opening it.

How a leak call-out runs.

Step 01

We ask about the floor

Whether the house is on a slab and whether any part of the floor is warm. Those two answers narrow it enormously before anybody arrives.

Step 02

Thermal imaging a slab leak in Seven Hills

Located with equipment

Acoustic listening, pressure testing on hot and cold separately, and thermal imaging over the suspect area.

Step 03

Options set out

Open one small area, or abandon the run and re-route it. Both get priced so you are choosing rather than being told.

Step 04

Repaired and written up

What failed, where, and what it took, at the figure agreed before we started.

There is a warm patch on my floor. What is that?

On a house built on a concrete slab, that is one of the clearest signs there is of a leaking hot water line running within or beneath the slab. The water is heated, the slab conducts, and the warmth reaches the surface above the leak. It is one of the few plumbing faults that genuinely tells you where it is.

What else points to a slab leak?

A sound of running water when every tap is closed. A hot water system that cycles more than it used to. A water bill that has climbed with nothing visibly wet. And in some cases a damp patch appearing at the edge of the floor where the slab meets a wall.

Does the slab have to be broken open?

Not necessarily, and not until it has been located precisely. Depending on where the line runs and what it serves, the options can include locating and opening one small area, or abandoning the affected run and re-routing it above ground or through the roof space. We would rather set both out than assume.

How do you find it without opening anything?

Acoustic listening, pressure testing on the isolated hot and cold lines separately, and thermal imaging, which on a warm slab leak is particularly effective. The point of all of it is to be certain before any concrete is touched.

A pipe has burst. What first?

Turn the water off at the meter before anything else, then ring. How much a burst costs is largely decided by how long the supply stayed on.

The bill has jumped but nothing is warm or wet. Still worth looking?

Yes. Close every tap and appliance and watch the smallest dial on the meter. If it creeps, water is genuinely leaving somewhere on your side, and under a slab it can do that for a long time without ever showing at the surface.

What does leak work cost in Seven Hills?

Locating a slab leak is $350 to $700. Locating a concealed leak generally is $250 to $600. A burst repair is $300 to $900. Re-routing an affected run is quoted once it is located.
