Leak Detection Lewisham

Same-day appointments are usually available in Lewisham, 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 Lewisham 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 Lewisham detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.

All of it, including Lewisham, Catford, Deptford, Forest Hill, Blackheath. We cover every London borough, so coverage never depends on which side of a postcode line you live.

Because the floor decides the method, and in this borough the floor cannot be predicted from the street. A suspended timber floor over a ventilated void routes water along joists and sole plates, so surface moisture readings mislead and the void has to be inspected through an airbrick or a lifted board. A solid floor with a screed holds water in place, so thermography and tracer gas both work well and the reading is meaningful where it is taken. Getting that wrong is not a small inefficiency, it is a survey that produces a confident answer pointing at the wrong room. Establishing the build up takes a few minutes with a borescope and it determines everything that follows.

It restricts opening up rather than instruments. Thermography, moisture mapping, acoustic correlation and tracer gas are all non contact or connect at existing valves, and none of them affects the external appearance that conservation area designation is concerned with. Where it becomes relevant is at the repair stage, and particularly where the failure turns out to be in a rainwater goods run, a parapet or a roof covering that is externally visible, since replacement in an unmatched material can be an issue. Locating the failure precisely limits that exposure, because the works are then a defined length of an existing element rather than an open ended proposal.

Almost always yes, and doing it the other way round is one of the commonest ways a claim gets into difficulty. A policy responds to an escape of water from a fixed installation, and the evidence that this is what occurred lives in the failed component and in its immediate context. Once the area has been stripped, the pipe cut out and the wet material removed, the cause can no longer be demonstrated and the position rests on recollection. The order that holds up is to establish and document the loss by measurement, locate and photograph the failure in situ with its position recorded against fixed features, agree the scope of opening up on that basis, and only then begin removal. It also prevents the other common outcome, which is a strip out that turns out to have been in the wrong room.

It matters both for how the survey is set up and for why the failure happened. Where dissimilar metals are joined in a wet system, the less noble one corrodes preferentially at the junction, and a galvanised steel section jointed directly to copper will fail at that point long before either would have failed alone. In a borough where properties were repaired piecemeal over decades, those junctions are common and they are exactly where to look. For the survey itself, a change of material is also a change of acoustic propagation velocity, so a correlation run across a mixed material span will return a wrong offset unless the position of the transition is known and entered. Establishing the materials along the run is therefore a prerequisite, not a detail.
