No find, no fee
Applies to leaks starting in your own property; pinpointing a neighbour's counts as a find.
All of Greenwich
Same-day and next-day cover across the whole borough.
Insurer-ready reports
Trace & access documentation loss adjusters accept.
Multi-method survey
Acoustic, thermal, tracer gas and moisture on every visit.
Local knowledge
How Greenwich properties leak
Greenwich housing is dominated by period conversions, post-war estates and new riverside towers. New riverside developments run plastic push-fit pipework in ceiling voids; a single failed O-ring can soak several flats before it surfaces.
Knowing the local building stock matters: it tells us where the pipework usually runs, which materials to expect, and which detection method will get to the answer fastest, before we arrive.
Covered in Greenwich
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss
- Underfloor heating loop leaks
- Flat-to-flat leak origin investigations
- Trace & access reports for insurance claims
Three methods, one marked point
Acoustic survey
Ground microphones and correlators follow the sound of escaping water through floors and ground.
Thermal imaging
Infrared cameras reveal wet patches and buried heating runs through the floor surface.
Tracer gas
A safe hydrogen mix escapes through the exact failure point and rises to our surface detector.
Common leak problems in Greenwich
Push-fit pipework leaks in ceiling voids
Across Greenwich's new riverside towers, plastic push-fit pipework is installed in ceiling voids. A single failed O-ring can cause a hidden leak that soaks through multiple floors before any visible signs appear. This demands urgent detection to prevent extensive structural damage to multiple flats.
Leaks in period conversion pipework
Many period conversions in the borough have ageing, often modified plumbing systems. Original lead or galvanised steel pipes may have been patched with newer fittings, creating weak points. Leaks can develop suddenly at these junctions, often within walls or under floorboards.
Post-war estate heating system leaks
Post-war estates often have centralised heating systems with ageing radiators and pipe runs. Corrosion and scale build-up over decades can lead to pinhole leaks in pipes or radiator valves. These leaks can quickly escalate, causing water damage to neighbouring units and common areas.
Balcony drain & cladding leaks in towers
Modern riverside towers with balconies and complex cladding systems are prone to drainage blockages and seal failures. Water can ingress behind cladding or seep from a blocked balcony drain into the structure, mimicking a plumbing leak and requiring immediate tracing to its source.

How to Choose a Leak Detection Company in London: Speed is Everything
Choosing a leak detection company in London comes down to one critical factor: response speed. Here’s how to ensure you get immediate, 24/7 action.
Leak detection in Greenwich: FAQs
How quickly can you attend a leak in Greenwich?
Same-day appointments are usually available in Greenwich, 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.
Do you charge if you can’t find the leak?
No, so long as the leak is one arising inside your own property in Greenwich: attend, fail to locate it, and you are not charged the detection fee. It is not cover against the leak being someone else's. Where the trace ends at a neighbouring property, a communal riser or the mains before your boundary, we have located it and the visit is payable.
Can you provide a report for my insurer?
Yes, trace and access reports documenting the cause, precise origin and affected areas are available for every Greenwich detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Greenwich do you cover?
All of it, including Greenwich, Woolwich, Eltham, Charlton, Blackheath. We cover every London borough, so coverage never depends on which side of a postcode line you live.
What should I have ready if I live in a gated Royal Arsenal or Peninsula block?
Three things save more time than anything else: the concierge or estate number, the building and core name rather than just the postcode, and whether visitor parking or a loading bay can be used at that hour. If you can warn the desk that an engineer is coming, do. Where a heat network serves the building, say so as well, because a leak on that circuit is the operator's system rather than your plumbing and the route to fixing it runs differently. Check whether your development uses an app or portal for reporting, because in some of them that is the only route that reaches anybody overnight.
We are in a Georgian house in Greenwich town centre. Does the conservation status affect a night visit?
It affects what gets opened, not whether anyone comes. Original joinery, sash boxes, plaster and floorboards in a protected building are not something to attack by torchlight at two in the morning, so the overnight aim is to shut the supply, contain the water and protect whatever it is running towards. The tracing that follows is non-invasive by design, and any opening up is agreed in daylight with whoever has to consent to it. Photograph any original feature near the wet area now, while it is intact, rather than after it has been dried out.
How do we get equipment to the door in a development with barriers and underground parking?
By arranging it before anyone sets off rather than at the barrier. What helps is knowing whether there is a visitor bay or loading area usable at that hour, whether the height restriction on the car park ramp rules out a van, and which entrance actually connects to your core, since large developments frequently have several that do not link internally. If the desk can meet an engineer at a named door, say which one. That single detail removes most of the delay at the front of a night call.
Our building has a heat interface unit rather than a boiler. What fails in those?
Usually a component inside the unit rather than the pipework in the flat. A heat interface unit takes heat from the building's network and transfers it to your heating and hot water, and it contains valves, a plate exchanger, a pump in some designs and a set of connections, all in a cupboard. Leaks show up as water in the cupboard itself or staining on the floor beneath it, and because the network runs at pressure it does not stop on its own. Crucially, the unit is normally maintained under the building's contract rather than by the resident, so the fix comes through the operator. What you can do is isolate at the valves either side of the unit if they are accessible, catch what is coming out, and report it to the building straight away.

Leak detection is not one technique. It is a sequence: prove there is a leak, work out which system it is on, then use the method that suits the pipe, the floor and the failure. Here is how each method works and what defeats it.
