HERTFORDSHIRE, BEDFORDSHIRE & CAMBRIDGESHIRE
Hidden leaks in Enfield found with thermal imaging, acoustic and tracer gas equipment rather than by digging, with full written reports for insurance claims.

Leak detection in Enfield for the leak that is somewhere under the floor of a Bush Hill Park villa, behind the tiles of a Southgate en suite, or along the supply pipe of a Winchmore Hill garden, and that nobody has been able to find. We bring a thermal camera, a ground microphone, a tracer gas kit and a moisture meter, and we use them in the right order so that one floorboard comes up instead of ten. Ring 01462 506 374.
The water meter keeps turning with every tap shut. The boiler drops pressure and wants topping up every few days. A patch of floor is warm for no reason. A stain on a wall or ceiling dries out, then returns. The Thames Water bill has jumped with nothing in the house to explain it. There is a sound of water at night with nothing running. One of those has an innocent explanation more often than not. Two of them together mean water is escaping, and the sooner it is found the smaller the repair to the building around it.

Nothing is opened until the leak has been located. We start with the thermal camera, because it is fast and touches nothing: a hot pipe leaking under a floor throws a plume on screen, a cold one shows as an evaporative chill. If the pipe is under pressure we put the ground microphone on it and follow the noise along the run until it is loudest, which puts the leak within a tile or two. If neither has given a clear answer, or the leak is on underfloor heating in a screed, we drain the circuit, charge it with a safe hydrogen and nitrogen mix, and walk the detector over the floor until it finds where the gas is escaping. And throughout, the moisture meter tells us whether what we are chasing is a pipe at all, or a shower seal, a roof, or the ground.
London Clay, trees, and the pipe in the front garden. West of the Lea, Enfield sits on London Clay, and London Clay changes volume with its moisture: it shrinks when tree roots draw the water out in a dry summer, swells when the rain returns, and the geologists’ list of consequences includes fractured service pipes. The service pipe in question is the one between the boundary and your house, which moves with the ground, and it is yours rather than Thames Water’s. On the 1880s streets of Bush Hill Park and the older stock around Enfield Town it can still be lead. We find the leak on it and price either a repair or a new run in plastic.
Three storeys of Victorian pipework. Bush Hill Park, Winchmore Hill, the Edwardian avenues near Enfield Town station. Pipes routed through solid floors, joints that have corroded quietly for a century, and now and then a pipe somebody buried in a screed with no protection. The microphone does most of the work here and the camera confirms it.
The loft tank that is not a leak. Southgate, Oakwood, Palmers Green and Enfield Chase were built in the 1930s with a cold tank in the loft, and a float valve from the 1970s with an overflow that discharges somewhere unhelpful produces a damp ceiling that looks exactly like a burst. We check the loft before anyone lifts a floor.
Underfloor heating in screed. Enfield Island Village on the old Royal Small Arms Factory site, the Alma Road rebuild at Ponders End, the Meridian Water phases. Underfloor heating is common in anything built this century, a loop damaged during construction can stay silent for years before it declares itself as a boiler that keeps losing pressure and a patch of floor that is warm for no reason. Tracer gas finds the spot and the smallest possible area of floor comes up.
Showers that are not plumbing. A large share of “leaks” beneath a bathroom are a failed seal at the tray, a cracked grout line or a screen channel that has parted from the wall. The water only gets through when the shower runs. We test the shower separately from the pipework, because a sealing failure is not fixed by a plumber under the floor.
Flats and shared risers. The Edmonton Green blocks of 1965 to 1974, the towers at Ponders End, the newer developments by the Lea. A stain in your ceiling can be two floors up, and tracing it through a block without shutting the block down is a skill we have.
East of the A10 the ground changes. Ponders End, Enfield Lock, Enfield Island Village and Edmonton sit on the flat land beside the Lea, the Lee Navigation, the River Lee Diversion and the reservoirs, and the Island Village in particular was built on former marshland. Down there the leak that is not a leak is groundwater: a damp ground floor, a wet cellar in one of the older Ponders End terraces, or a stain at the base of a wall that has nothing to do with the plumbing and everything to do with the water table. The moisture meter and a pattern of readings across the floor tell the difference between a pipe that is leaking from above and ground that is wet from below, and it matters, because one is a plumbing repair and the other is a building problem we will tell you about honestly rather than sell you a pipe repair that changes nothing.
Water actively escaping: stopcock off, a cold tap open to drain the pipes. A slow leak with nothing visible: change nothing. No dehumidifier on the patch, no heater drying it, no floorboards lifted, because once a leak has dried out it has to be found again from scratch, and it is the contrast between wet and dry that the camera sees. Photograph the meter with every tap shut, and again an hour on. If the reading has moved, the water is escaping on your side of the boundary, and you can tell us that on the phone.
A fixed survey fee, agreed before we attend, not a clock running while somebody looks. In return: the leak located and marked at the property, a written report containing the thermal images and the readings, and a second fixed price for the repair should you want us to do it, which nearly everyone does, since the engineer who located it already knows what is beneath the boards.
Trace and access cover sits in most household policies and covers the cost of finding the leak and reinstating what was opened, even when the pipe repair is excluded. The report is written to give your insurer what they ask for: where the leak was, how it was found, photographs, what was opened up. Read your policy wording rather than assuming either way, and ring us if it is not clear.
Non-invasive first, every time. We locate the leak, show you the evidence and fix it properly.
Thames Water is responsible for the supply pipe up to your boundary. From there to the internal stopcock it is yours. The meter test with every tap shut is the quickest way to know which side the water is escaping on, and it sometimes saves you the visit.
A supply leak that has run for months shows up as a bill, and on a metered property in Enfield it can be a large one. Once the leak is repaired and the meter has stopped turning, ask Thames Water about a leakage allowance on the metered volume that was lost, which is something most water companies will consider once for a property where the leak was on the customer’s side and has been fixed. Our report gives the dates, the location and the repair, which is what the request needs. We cannot promise what Thames Water will grant, but we can make sure you ask with the right paperwork in hand.
Water leak detection in Enfield covers both sides of the meter: the supply pipe between the boundary and the house, and everything inside it. The same thermal camera, ground microphone and tracer gas kit find both, and the report says which it was, because a leak on the supply pipe is yours to fix but may earn a leakage allowance from Thames Water once repaired, while a leak on the heating circuit is a job for the same engineer who found it.
Once found, most leaks are everyday repairs for plumbers in Enfield. A heating system that has been topped up for months is full of sludge and needs a power flush in Enfield once the leak is fixed. Water surfacing at a gully or a manhole is drainage, not a supply leak.

Yes. The camera if the pipe is hot, the microphone if it is pressurised, tracer gas if neither is conclusive. The floor is opened once, where the leak is.
Tracer gas. It is the standard method and it works through screed.
Yes, on a separate fixed price agreed before the repair starts.
Trace and access cover is in most household policies. Our report is written for it. Check your wording.
Nearly always, on the heating pipework or occasionally inside the boiler itself. The boiler is where we start, since it is the quickest thing to rule out.
Because the water only arrives when something is used, a shower, a washing machine, rain on a flat roof. That points to a seal, a waste or the building rather than a supply pipe, and the moisture meter settles which.
With thermal imaging, acoustic listening equipment and tracer gas, in that order. Thermal imaging shows the temperature change a leak leaves under a floor or behind a wall, acoustic equipment picks up the sound of escaping water in pipework, and tracer gas finds pinhole leaks the other two cannot. Together they pinpoint the leak so only the spot that needs opening is opened.
A typical leak trace takes around half a day. We tell you the price on the phone before we book, and once the leak is found you get a fixed written price for the repair before anything is opened up. We provide a full written report with photographs for your insurer.
Most buildings policies include trace and access cover, which pays for finding the leak and for making good the floor, wall or ceiling that had to be opened to reach it. The repair to the pipe itself is often excluded. Check your policy wording, and use our written report and photographs to support the claim.
From the boundary of your property inwards, including the pipe between the outside stop tap and the house, the pipe is yours. The water company is responsible for the mains and the pipe up to the boundary or the meter. If your water bill has jumped and there is no obvious leak inside, the supply pipe is the first thing we test.
