How Do You Know a Leak Is Hiding?
A dripping tap is easy to spot. Hidden leaks give quieter signs:
- The meter dial keeps turning when nothing in the house is running
- A bill that keeps rising even though nothing about your usage has changed
- One patch of lawn or garden that stays damp while the ground around it dries
- Staining, blistering paint or a musty smell on a wall or floor with no obvious source
- Hot water that runs out fast, which can point to a leaking line under the floor
Any one of these deserves a proper look. A leak behind a wall or under a slab never fixes itself, and the damage compounds the whole time it stays hidden.
How the Trace Runs
- 01
Test the system
We read the meter and run a pressure drop test to confirm a leak exists and narrow down which section of pipework is losing water.
- 02
Listen along the line
Acoustic detection equipment pinpoints the spot the water is escaping, so the repair targets one joint or one run rather than a guess.
- 03
Show you the finding
You see where the fault sits and what caused it, with the price settled, before any wall, floor or paving comes open.
- 04
Repair and confirm
Once the fix is in we test the line again to confirm the loss has stopped, and the work carries our 365-day warranty on all work.
What Decides the Cost of a Trace?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
No tile comes up until you have that price. The main drivers:
- Depth: a weep in an exposed copper line under the house is quicker to reach than one in a supply run under the driveway
- How many sections of supply have to be isolated before the loss shows up
- What the repair needs once the leak is found: a fitting, a short section of pipe, or a longer run that has simply worn out
The Housing Here Keeps Leaks Quiet
Old pipework plus moving ground. The ground under Lambton is reactive clay on a shale base, and it swells and shrinks between wet and dry spells. That movement works joints loose in supply runs that have been in the ground since the miners' cottages were built, and the area's average rainfall of 1,076 millimetres a year repeats the cycle often enough to turn a slow weep into a running leak.
The 1894 Mechanics Institute on Elder Street has ridden out every one of those seasons, and plenty of cottages in the streets around it carry supply runs nearly as old. Electronic detection finds the joint at fault before original floors or linings come open, which keeps a small repair from turning into a renovation nobody budgeted for.
When We're Not the Right Call
Damp that comes from a shower whose waterproofing has let go, with every pipe testing sound, is work for a waterproofer or builder. If the water is coming from a waste pipe instead of a supply line, blocked drains is the better starting point.
Straight Answers on Hidden Leaks
Can you find a leak under a slab without breaking the concrete?
Yes. Acoustic listening gear and a pressure drop test narrow the fault to a spot before anything is opened, so only the small section at fault gets exposed. On the older cottages around Lambton that saves original floors from exploratory digging.
Why is my water bill climbing when nothing is dripping?
A buried supply line can lose water day and night with nothing visible, and reactive clay soil hides the damp even longer. We test the meter, isolate sections and trace the run to the point it is escaping.
Do you check older Lambton cottages for hidden leaks?
Yes. Many of the pre-1940 homes here still run their original supply pipework, and joints shifted by a century of soil movement weep quietly under floors and behind walls. Detection finds them before the damage shows.
What happens once the leak is found?
You get the location and cause in plain terms, then a firm price for the repair. If the pipework is past its useful life we price the options honestly rather than patching a line that will let go again.
