How Do You Know a Leak Is Hiding?

A leak behind plaster or beneath floorboards seldom makes itself obvious. The clues tend to build slowly:

  • A water bill well above what the household normally uses
  • A hot water tank heating up again when nobody has touched a tap
  • Damp marks, loose tiles or one warm patch on a tiled floor
  • The sound of running water in a silent house
  • A stripe of lush green lawn in a dry spell, or a dip forming in the garden

Test the meter. Read the meter at bedtime once every tap is off, then another first thing in the morning before anyone uses water. A changed number means water is leaving the pipes somewhere past the meter, so book a trace.

How Does a Leak Trace Run?

Finding comes before fixing, so the repair lands in the right spot first time.

  1. 01

    Isolate and test

    Parts of the supply are closed off and put under pressure to prove there is a leak and narrow down which section holds it.

  2. 02

    Listen

    Acoustic detectors pick up water escaping a pressurised pipe through concrete, brick and garden soil.

  3. 03

    Locate and mark

    A pipe locator follows the line, and the loudest spot gets a chalk mark so only a small patch is opened.

  4. 04

    Repair and retest

    The failed length is fixed or replaced, the pipe goes back under pressure, and you see the result before anything is closed up.

Where the escape is from waste pipework instead of the supply, CCTV drain inspection takes over with footage from inside the pipe.

What a Leak Trace Costs

The price comes down to:

  • Whether the leak is somewhere easy to reach or under a slab, where tracing takes longer and the repair needs a careful cut
  • How much pipe needs renewing once the fault is exposed, as an old pipe near a split can be weak for some distance
  • The pipe material, since ageing supply pipe in the earliest estate homes can call for more than a spot repair

Where Leaks Hide on the Estate Blocks

Supply lines from the first build waves

Maryland was farmland until housing began in the 1970s, and the brick-veneer homes built then have water pipes that have now been in the ground for decades. In those earliest stages, joints and fittings are old enough to start weeping.

Clay ground that moves

The same reactive clay that opens old sewer joints also shifts buried water pipes as it swells and dries. A seeping joint below the slab can go unnoticed for months until the bill or a damp patch gives it away.

Wet ground on the low side

Blocks toward the Hexham Swamp edge sit on lower, wetter land, and damp soil there can hide a slow leak in a garden line for a long time. On any block, a tiled floor that feels warm in one place deserves a look.

"The team … were fantastic in quickly assessing a massive water leak at my place. They also went above and beyond in fixing it promptly." Nitin

When We're Not the Right Call

Sometimes the pressure test holds and the damp is coming from a shower whose tiled floor has lost its seal. Redoing the membrane under that shower belongs to a waterproofing contractor, and the test result shows which problem you have.

A gas smell needs a different process altogether, set out under gas leak detection, and a drain that keeps blocking belongs with the blocked drains work rather than a leak trace.

FAQs

How much water can a hidden leak waste in a Maryland home?

A lot, because it never switches off. A cracked pipe under the slab loses water every hour of the day, and damp ground can hide it for months. To check, write down the meter reading, use no water for an hour, then read it again.

Do you find leaks under concrete slabs in these estate homes?

Yes. Listening equipment picks up the hiss of a leak below a slab or lawn, and a pipe locator follows the line so the opening can be kept small. On estate homes from the 1970s onward, the fix then goes in through that one opening.

Is a rising water bill always a sign of a leak?

No, but it is worth checking. If the bill has jumped well beyond your usual use, do a meter test first. A meter that creeps while everything is off means book a trace; one that stays still means the water is being used somewhere.

Can you check a rental or strata property for a suspected leak?

Yes. The tenant gets a text to lock in the visit and another as we head over, and the owner or agent gets photos and a written invoice showing what was found and what was fixed. The rental and strata process sets out the full routine.
