How Do You Know a Leak Is Hiding?

Most hidden leaks stay quiet for a long time. They begin as a pinhole in a corroded joint or a hairline crack where two materials meet underground, and the water escapes into soil, a wall cavity or the sand base under a slab.

The water meter dial still turning with all taps and appliances off
Damp patches or lifting paint with no obvious source above them
Hot water giving out sooner than it should, which can mean the hot line is losing water
A faint hiss inside a wall, easiest to hear late at night
Patches of yard that stay greener and softer than the rest

One clue alone justifies a trace call. Water that has nowhere to show itself does its damage invisibly, and the repair bill grows the longer it hides.

How the Trace Runs

Guessing costs you floorboards, so a trace follows a set order.

01
Isolate and test
With the supply turned off, the house pipework is pressure tested one section at a time. The section that loses pressure holds the leak, which narrows the search area before any gear comes out.
02
Listen along the line
Listening equipment picks up the escape point's signature through the ground or slab, and a pipe locator maps where the run travels so we follow the pipe, not a hunch.
03
Confirm before we cut
We check the suspected point from more than one direction before drilling a hole or lifting a paver, and show you the spot.
04
Quote, then repair
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead. The repair is done on the same call where the fault allows it.

If the leak turns out to be in a waste or stormwater pipe instead of the pressure line, the blocked drains hub deals with it, and a CCTV drain inspection puts the pipe's interior on screen.

How Is a Leak Trace Priced?

A trace is priced on where the pipe runs and what it is made of:

Under timber or under concrete

A joint below a raised floor is easy to reach, and one beneath a slab or driveway means cutting in

Steel, copper or plastic

Corroded galvanised pipe is replaced once found, not patched

Repair or renewal

Fixing one joint is small, and renewing the whole water service is a larger job

After-hours tracing

A higher rate applies, and you hear it when you book

Nothing gets opened up on a maybe.

Why This Suburb's Leaks Hide So Well

Steel services rust shut quietly

Galvanised water pipes were the standard fit when the Gateshead West estate went up between 1964 and 1967, and a great deal of it is still in the ground. That steel corrodes from the inside, so a pipe can be half closed and still pass water, and a damp carpet may be the first sign instead of a burst.

Patchwork junctions are the weak point

Years of piecemeal landlord repairs on tenanted commission-era houses have joined fittings from different decades underground, and those joins are where old and new metal part company. The reactive clay under these blocks moves between soaked and baked, so a joint that weeps now can open wider by autumn. A trace that names the exact section saves you digging up the wrong stretch of yard.

When We're Not the Right Call

A failed shower membrane

If the water is getting past tiles and a broken waterproof membrane instead of a pipe, a builder or waterproofer fixes that, and we name the trade instead of charging for work that won't stop the leak.

Smell of gas, not damp

If what you can smell is gas, that is a different safety process entirely: the gas leak detection page sets out the first steps, including clearing the house and using the network's emergency line before anything else.

Leak Questions From Gateshead Homes

My water bill jumped but I can't see a drip anywhere. Could a leak be hidden?

It could well be, since a buried or in-wall leak shows on the meter before anywhere else. Turn off every tap and appliance and watch the dial for two minutes; if it moves, water is escaping and a trace will find it.

Can you find a leak under the concrete slab of a Gateshead home?

Yes. We pressure-test the line first, then follow the pipe's path with a locator and listening gear to narrow the escape point before anyone drills a hole. You get the spot marked and a fixed figure for the repair before the concrete is touched.

Is a slow leak in a commission-era cottage urgent?

Book a trace soon. Old galvanised pipe gets worse without showing it, and the shifting clay here opens joints further each season, so a small drip now can be a slab problem within a year.

Do you trace leaks on hot water pipes as well as cold?

Yes. A hot pipe leak can show up as the tank running out early. We trace it the same way as a cold pipe: isolate, test, listen, confirm, then quote.
