Leak Detection Wandsworth

Same-day appointments are usually available in Wandsworth, and next-day almost always. If water is actively escaping, tell us when you book. Live leaks are prioritised and we can talk you through isolating the supply while an engineer travels.

Not on a leak arising within your own property that we cannot find: in Wandsworth that detection fee is waived. Trace it instead to a neighbour's pipework, a shared riser or the water main beyond your boundary and the fee stands, because that is a located leak, and it is the finding that moves the repair bill off you.

Yes. Trace and access reports documenting the cause, precise origin and affected areas are available for every Wandsworth detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.

All of it, including Battersea, Putney, Balham, Tooting, Earlsfield. We cover every London borough, so coverage never depends on which side of a postcode line you live.

Thermography is the right first instrument on a wet underfloor circuit, but it rarely finishes the job on its own. It shows where the loops run and where the floor is warm, and a failing loop often shows as a zone that warms or cools at a different rate from its neighbours, which means the survey has to image through a controlled heating and cooling cycle rather than take a single frame. What it cannot do is convert a warm band into a point, because the screed spreads heat laterally. For that the circuit is isolated at its manifold, drained and charged with tracer gas, which leaves at the failure and surfaces through the floor finish where a probe can find it.

By dating the build up before diagnosing anything. A borescope or an existing access point establishes what each floor actually is: original suspended timber over a ventilated void, a 1980s slab, a modern screed over insulation, or a basement slab with a cavity drain membrane. Each of those routes water differently and each responds to different instruments, and the affected area is frequently in a different construction from the failure. Once the build up is known, the candidate systems in each zone are isolated and pressure tested in order of how cheaply they can be excluded. It is a short stage and it prevents the common outcome of a confident reading taken in the one part of the house where that method does not work.

The most likely explanation is that the pumped drainage stopped. A cavity drain system does not keep water out, it collects what arrives at a perimeter channel and pumps it away, which means the basement is dry only for as long as the pump runs. A tripped circuit, a failed float switch, a silted chamber or a simple power cut will fill the channel and then the floor within hours, and it typically happens at night when nobody notices. This is why these systems are specified with a second pump on an independent supply and a battery backup, and why the alarm needs to be audible somewhere a person actually is. Where a survey finds a single pump on a single unprotected circuit, that is the finding, and it is a more useful one than a pipe location would have been.

Because the wet services for it were installed above a ceiling that was never designed to be a floor, and the run to reach it is long. A loft en suite typically requires hot and cold supplies taken up from the floor below, a waste that has to be driven horizontally with limited fall to reach the stack, and very often a macerator or a pumped waste where gravity will not do it. Each of those is a failure point above the original top floor ceiling, and any escape has the full height of the house to travel. Add that the pipework sits above the insulation line in a cold roof void in many conversions, and frost becomes a live risk. It is the first area to survey when the affected ceiling is on the top floor.
