Leak Detection in Langford
Locate it first, lift second
A hidden leak is not a digging job, it is a finding job. We use thermal imaging, acoustic detection and tracer gas to put a mark on the floor where the fault actually is, so if anything has to come up, it comes up once, in the right place, and it is small.

Why the ground in Langford hides leaks
Langford sits on the west bank of the River Ivel, and the ground the village stands on changes the way leaks show themselves. Anyone doing leak detection here without knowing that is guessing.
The village itself sits on river gravel. Gravel drains freely, which is good news for soakaways and bad news for finding leaks, because water escaping from a buried supply pipe disperses down through the gravel instead of pooling at the surface. A leak that would leave an obvious wet patch on heavy clay can run for months here with nothing to see. The first and often only symptom is the water bill.
Alongside the river it flips the other way. The soils on the floodplain edge, down towards Henlow Common and Langford Meadows, are loamy and clayey floodplain soils with naturally high groundwater. Down there the ground is damp anyway, so a damp reading at the base of a wall near Mill Lane or Common Road is not proof of a plumbing leak. It might be groundwater. We measure and cross check rather than taking a moisture meter reading at face value, because opening a floor to chase groundwater helps nobody.
East of the village the ground rises towards Topler’s Hill, and the fields out that way are boulder clay over Gault. Clay shrinks and swells with the seasons, and that seasonal movement is a classic cause of stressed joints and cracked pipework on longer buried runs to properties set back off the road.
One more thing about the shape of the place. Langford is a straggling village, nearly two miles long along the B659 through High Street and Church Street. Long frontages and set back plots mean long private supply pipe runs, and the longer the buried run, the more there is to go wrong and the more valuable it is to pinpoint the fault rather than dig on a hunch.
The signs, in the order people notice them
The water bill jumps. Anglian Water supplies Langford, and a bill that rises with no change in the household is the most common reason the phone rings. If the meter keeps turning with every tap and appliance in the house off, water is escaping somewhere between the meter and your taps.
Boiler pressure keeps dropping. Topping up every week or two with nothing visible under any radiator almost always means a heating circuit is losing water into a floor or a wall.
A warm patch on a solid floor. Heat from a leaking heating pipe comes up through screed and tile. People notice it in socked feet before they notice anything else.
Damp that will not dry. A skirting or a patch of carpet that stays damp whatever you do. Near the river this needs careful interpretation, for the groundwater reason above.
A hiss in a quiet house. Usually near the stopcock or the incoming main, and usually at night when the village is silent.
How we find it
Thermal imaging. A thermal camera builds a map of the temperature across a floor or wall. A heating leak shows as a warm plume, a cold mains leak as a cold anomaly. It reads the surface rather than seeing through it, so we use it alongside the other methods, but it is nearly always where we start because it is completely non invasive.
Acoustic detection and correlation. A pressurised leak makes noise. Ground microphones pick it up, and a correlator listening at two points on a pipe can narrow a buried leak to a short section, which on a long Langford supply run is the difference between one small hole and a trench the length of the front garden. Acoustic work performs best on metal pipe. Plastic carries sound poorly, so on newer plastic runs the next tool takes over.
Tracer gas. We isolate and drain the suspect pipe, then introduce a hydrogen and nitrogen mix, harmless and non flammable at the concentration used. The gas escapes through the smallest defect and a detector finds it at the surface. This is what finds the leaks nothing else will, especially under screed and solid floors, and especially in free draining gravel where water leaves no surface trace.
Moisture meters and hygrometers. For mapping how far the water has travelled, separating leak damp from groundwater damp, and confirming afterwards that the building is drying out, so you know the repair actually worked.
Isolation and pressure testing. Sometimes plain discipline is the fastest route: valve by valve, circuit by circuit, proving which part of the system is losing water before any equipment comes off the van.
Where the leaks are in Langford's housing
Langford’s housing has an unusually clear age map, and the age of the house tells us a lot about where the water is going before we arrive.
The old spine along High Street and Church Street. The pre war and Victorian stock, including terraces like Denny Cottages from 1862, is where the oldest pipework lives. Lead and iron supply pipes, solid walls, shallow and uneven joists, and pipe runs altered many times over. Old metal supply pipes corrode from the inside out, and the private section from the boundary into the house is the homeowner’s responsibility, not Anglian Water’s, which surprises most people. On these houses the leak is as likely to be under the front path as under the kitchen.
Riverside Gardens, from the late 1960s. The first of the modern estates, and prime territory for heating pipework buried in solid floors, often without sleeving. Where a pipe passes through concrete, corrosion at the contact point is a classic failure. These houses also sit towards the river side of the village, so damp readings need the groundwater cross check.
Wilmon Court and Ivel Close, from the 1980s. Small bore and microbore heating pipework from this era pinholes, and an 8 mm or 10 mm pipe weeping into a floor void can go unnoticed for a long time because the loss is slow. A dropping boiler pressure gauge is usually the only clue.
Garfield, Rowley Fields, Merryweather Grove, Steamer Croft and the newer schemes around Bramble Corner, Mayflower Lane, Campion Edge and Elderberry Close. Modern pipework fails less, but when it does it is usually a fitting: a pushfit joint buried behind boxing during a refit, a concealed valve with no access panel, or underfloor heating in a rear extension. UFH leaks are among the easiest faults we locate, because the temperature signature through the floor is very clear on a thermal camera, and that means opening one small square of screed rather than the room.
Shower trays and wet rooms, in every era. A steady share of calls that come in as plumbing leaks turn out to be sealing failures: water getting past a tray edge, a failed seal at the waste, or tanking that was never continuous behind the tiles. No amount of pipe testing finds that, so we test the tray and the enclosure separately, and if the fault is a seal rather than a pipe we tell you so plainly.
One more local factor. The water here is hard. Anglian Water supplies the village from its Potton Public Water Supply Zone, drawn from groundwater boreholes in chalk fed ground, and hard water is tough on concealed fittings, thermostatic cartridges and compression joints over the years. Scale does not cause every leak, but it shortens the life of the weak points.
Insurance and trace and access
Many buildings insurance policies include trace and access cover, which deals with the cost of finding the leak and reinstating whatever had to be opened to reach it, separately from the pipe repair itself. Policies differ and we are not going to tell you what yours covers, because that is your insurer’s decision, not ours. Take a look at your schedule for trace and access wording and speak to your insurer before signing off on any work. The report we hand over sets out our findings, the thermal images and exactly where the fault sits, in the form your insurer wants.
If water’s escaping right now, get the stopcock off and give us a ring. Where it’s the heating system leaking, turn the boiler off and stop repressurising it. Each time the pressure is topped up, more water is going straight into your floor.
What it costs
A detection visit is priced as a job, not by the hour, so you know what you are committing to before we start. What it costs depends on the size of the property, which system is under suspicion, and whether the pipe run is internal or buried. Repairs are quoted separately once the fault is found, because a repair price given before then would be invented. No online booking, no gimmicks: call 01462 506374 and we will talk the symptoms through first, because sometimes a five minute conversation rules a leak out.

Related work in Langford
Finding it is half the job. We repair what we find: renewing lead and iron private supply pipes on the older Church Street and High Street stock, repairing heating pipework and underfloor circuits under screed, and rebuilding trays and tanking where the leak was a seal. Where the investigation turns up a tired, sludged heating system rather than one failed joint, power flushing in Langford covers that, and where the water is coming from a drain rather than a supply pipe, drainage services in Langford picks it up. For everything else there is general plumbing in Langford.

Frequently asked questions
Will you need to dig up my floor to find the leak? No. Thermal imaging, acoustic tracing and tracer gas locate the fault from above. Any access needed for the repair is one precise, targeted opening in a location we already know, not guesswork holes.
There’s been a jump in the water bill without any sign of a leak in the property. How? Langford sits on river gravel, which drains freely. Water escaping from a buried pipe disperses downwards through the gravel and may never show at the surface. A rising bill with no visible water is a classic presentation here.
The bottom of my wall is damp. Is that definitely a leak? Not necessarily, especially towards the river. The floodplain soils near the Ivel carry naturally high groundwater, so damp near Mill Lane, Common Road or Riverside Gardens can be the ground rather than a pipe. We measure and cross check before anyone spends money on a repair.
Whose job is the pipe between the road and my house? Yours. Anglian Water is responsible up to the property boundary, and the private supply pipe from the boundary into the house belongs to the homeowner, including its repair. On Langford’s long plots that pipe can be a considerable run.
Will my insurance cover the cost? That’s entirely down to your policy wording, and it isn’t something we can answer on your behalf. Check your schedule for trace and access cover, then run it past your insurer before work starts. We provide the written report insurers usually ask to see.
How long does a visit take? Typically two to four hours. Properties near the river can take longer, because we cross check acoustic and moisture results against thermal imaging and tracer gas rather than trusting one reading in ground that is naturally wet.
