Let’s Fix Group Ltd traces hidden leaks across Wandsworth by acoustic, thermal and tracer gas methods, then repairs and reinstates. Call and talk to one of our leak detection specialists about the damp.
The process is the product here. The property is isolated to prove there is a live leak, the run is narrowed acoustically, thermally or with tracer gas, two methods have to agree on the same spot, and only then does a floor come up. The opening is the last step.
The Quick Answer
- Hidden leaks located by acoustic, thermal imaging and tracer gas methods, not by digging.
- The opening is the smallest area that reaches the fault, then made good.
- A written record of where the leak was and how it was found, for a trace and access claim.
- Detection and repair by the same team, so no second firm and no second bill.
- Cover around the clock, with a person answering rather than a message service.
David Prince heads a team of expert engineers across London and the South East, and the same people handle boiler repair in Wandsworth when the pressure loss turns out to be the appliance rather than the pipework.

What Leak Detection Covers
The job is finding water you cannot see, without taking the house apart to do it. That covers supply pipework, heating circuits, hot and cold feeds, and leaks running under solid floors where nothing shows on the surface until a ceiling gives it away.
It also covers telling you when the water is not a supply leak at all. A failed waste run, condensation in a cold corner or rain getting in at a parapet all read as damp, and they are three different repairs with three different costs. You get told which one you have before anyone quotes for anything.
A boiler losing pressure every few days belongs here too. That is a leak on the heating circuit, usually a joint under a floor, and proving it before somebody prices a new appliance is the single most useful thing a detection visit does.

Common Signs of a Hidden Leak in Wandsworth
The obvious one is a stain that grows. The less obvious ones matter more, because they show up months earlier: a meter that ticks over with every tap in the house shut off, a patch of floor that is warm underfoot, a musty smell in one room, or pressure on the boiler gauge that needs topping up more often than it used to.
Where the water shows is rarely where it comes from. Around Wandsworth Common the stock is highly intact Victorian and Edwardian property, described as two and three storey terraces and villas, and in those houses water runs sideways along joists and down inside a wall before it appears. The stain is a symptom of travel, not a location.
The other local pattern is age. Eighty per cent of the borough’s housing was built between 1940 and 1980 and only five per cent since 2001, so a great deal of the pipework in Wandsworth has had decades of thermal movement through it. Joints fail at the point where they were always going to fail.

Leak Repair and Reinstatement in Wandsworth
Finding it is half a job. The engineers here are plumbers first, so the same visit usually carries the repair once you have seen the evidence and agreed to it, rather than handing you on to a second firm with a second bill.
The opening is the smallest area that reaches the fault, sheeted and contained before anything comes up. A failed joint is remade in the right fitting for the pipe it sits on, because lead to copper and copper to copper are not the same connection, and where a length is beyond patching it is replaced rather than taped over.
Then it goes back. Floors are reinstated, the property is left as it was found, installation work carries a 10-year guarantee and the business is fully insured. Whether you need a leak detection in Wandsworth or a leak detection in Putney, it is the same engineers and the same standard either side of the boundary.

How the Investigation Works
It runs in an order, and the order is the point. First the property is isolated section by section to prove there is a live leak at all, and to establish whether it is on the supply, the heating circuit or neither. A great many call-outs end here, correctly, with no floor lifted.
Then the run is narrowed. Acoustic listening picks up a pressurised leak through a solid floor, thermal imaging shows a hot feed where it should not be, and tracer gas is used where the circuit has already been drained down. No single method is right everywhere, which is why more than one is carried.
The opening comes last, and only where two methods agree on the same spot. That is the whole answer to the fear of paying for an inspection that wrecks the place and finds nothing. Whether you need a leak detection in Wandsworth or a boiler installation in Wandsworth once a tired appliance is ruled in, it stays with one team.

Emergency and 24/7 Callout Support
Water does not keep office hours. Cover runs around the clock and a person answers rather than a message service, because the description of what is happening decides what goes on the van.
On an active leak the first instruction is isolation, and if you do not know where your stopcock is you get talked to it on the call. Minutes of running water cost more than the visit will. In the borough’s 1920s garden-suburb estates and the Dover House Road estate the stop tap is often in a hall cupboard or an external box that has not been opened in years.
Attendance holds up because there are engineers based in and around the borough rather than one van crossing London, and nine out of ten repairs are finished on the first visit.

Non-Invasive Detection Methods
Non-invasive means the equipment does the looking instead of a chisel. Acoustic listening equipment amplifies the sound a pressurised leak makes escaping a pipe and narrows it to a length. Thermal imaging reads surface temperature, which finds a hot feed under a floor and often the cold plume of a mains leak. Tracer gas is introduced into a drained circuit and detected where it surfaces, which is what works when there is no pressure and no heat to find.
Equipment is only half of it. The reason two methods are used is that each has a blind spot, and agreement between them is what turns a guess into a location worth opening a floor for.
What you are left with is a written record: where the leak was, how it was located, what was opened and what was put back. Our water leak detection work produces that document as a matter of course, because it is exactly what an insurer asks to see on a trace and access claim.

Common Questions About Leak Detection in Wandsworth
What is the average cost of leak detection?
It depends on the property, the access and how far the water has travelled, so the figure is confirmed before the visit rather than after it. What will not happen is a number given down the phone and then revised once the equipment comes out of the van.
How to check where a leak is coming from?
Start with the meter. Turn every tap and appliance off, note the reading, and check it again after an hour. If it has moved you have a live leak on the supply. If the boiler gauge is the thing dropping, the leak is on the heating circuit instead, and those are found different ways.
Does home insurance cover leak detection?
Most policies carry trace and access, which pays for finding the leak and making good what had to be opened to reach it. Read your own wording before work starts. The written record of the investigation is supplied as standard, because that is the document an insurer will ask for.
Do you find leaks in the Victorian terraces around Wandsworth Common?
Regularly. The housing around the commons is highly intact Victorian and Edwardian property, mostly two and three storey terraces and villas, which means older heating layouts and constrained access through side returns. Water travels a long way along the joists in those houses before it shows.
Our Wandsworth house is a post-war build. Does that change anything?
It changes where we look first. Eighty per cent of the borough's stock was built between 1940 and 1980 and only five per cent since 2001, so the pipework has had decades of thermal movement and the failures tend to be at the joints rather than along a run.
