What Are the Signs of a Hidden Leak?

The obvious ones announce themselves. The hidden ones leave clues first, and each is worth a call:

The meter creeping or spinning with every tap in the house shut off
A damp patch, a bulging wall or a floor that's warm in one spot for no reason
A hiss behind plasterwork when the house is quiet at night
A musty smell or staining that returns no matter how much you scrub
A bill that jumps a tier without a change in how the house uses water

A slow weep can run for months inside a wall cavity before it shows. Caught early, it's a small repair; caught late, it's a rebuild of whatever it soaked.

How We Track Water to Its Source

01
Ring or send the form
Call (02) 4093 0558 or use the form to explain the fault. We ask enough to bring the right equipment the first time.
02
A fixed price first
A plumber inspects the job and names a fixed figure up front. Nothing gets started until you give the go-ahead.
03
Traced and marked
Listening gear, pressure testing and a pipe locator shrink the search to one marked spot before anything gets opened up.
04
Covered for a year
Every job carries our 365-day warranty on all work. If something we did isn't right, ring the same number.

Once the point is marked, the repair is usually a small, surgical job: one opened section of pipe, one join, one patch of wall. If the locator work shows the pipe itself is finished, you see the evidence and we talk through replacement, or pipe relining where the failing line is a drain.

What Changes the Price of Leak Work?

We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.

What moves the number:

Where the escape sits A worn washer under a sink is a short visit; a buried run under a driveway means tracing, marking and opening a surface.
The pipe material Cutting into corroded galvanised steel is a different job to working with sound copper, and the older the line, the more care the repair takes.
The repair scale A single joint is one price; a supply line that's rusted through in three places is a replacement conversation.

If the trace points to a burst rather than a weep, the emergency plumber page covers what happens in the first hour.

Where the Hidden Leaks Sit in This Town

Galvanised lines that weep from the inside

Cottages from the Excelsior era, close to the lake, still run galvanised water pipes in places, and it corrodes from within until pinholes open behind painted walls. The stain you see is usually a metre from the hole that made it.

Ground that moves with the seasons

The reactive clay and alluvial soils around the lake edge swell and shrink with wet and dry spells, and annual rainfall averages 1,092 mm, so the ground rarely stays still for long. Joints in older pipe part a little each cycle, and a weeping joint under a floor is silent until the timber swells.

Damp that isn't a leak at all

Low-lying foreshore blocks stay damp long after rain, and owners sometimes chase a "leak" that's actually the water table. The pressure test settles which one you're facing before anyone cuts anything, and our foreshore stormwater work covers the drainage side if that's what it turns out to be.

When We're Not the Right Call

Once we trace a leak to a failed waterproof membrane under the shower, the rebuild is a builder's or waterproofer's job, not ours. And a smell of gas is never a water job; that runs through the gas leak page and the network's emergency line first.

Leak Questions From Around the Lake

My water meter ticks over with every tap off. Is that a leak?

Almost certainly. Shut every fixture, note the meter reading, wait an hour without using water, then read it again; if the dial has moved, water is escaping on your side. Ring us and we pinpoint the escape before any floor gets opened.

Can you trace an escape beneath the slab of an older Toronto cottage?

Yes. Listening gear picks up the sound water makes leaving a pipe under concrete, and the pipe locator maps the run so we know where to open. Most slab jobs finish with one small access hole rather than a torn-up floor.

The yard near the foreshore is always damp. How can you tell a leak from the water table?

Low-lying blocks here hold moisture from the lake side, so damp ground alone proves nothing. We pressure test the supply line and read the meter with everything shut off; if the pipe holds pressure, the damp is ground water, not a leak.

Do you repair the pipe once the leak is found?

Yes. Locating the escape is one job and repairing it is the next, quoted before we start. When the locator work points to a whole failing line rather than one joint, we lay out the repair and replacement options with the evidence in front of you.
