Leak Detection in Huntingdon
Locate it first, lift second
The worst way to find a leak is with a crowbar. We find leaks in Huntingdon with thermal imaging, acoustic listening and correlation, tracer gas and moisture mapping, so if a floor does have to come up, it comes up in one small place, once, over the actual fault.

Why hidden leaks are a Huntingdon problem in particular
Two local facts shape almost every leak detection job we do in this town.
The groundwater sits high. Huntingdon sits on the north bank of the River Great Ouse, directly opposite Godmanchester, and the district council’s own flood risk work for a Main Street site records a high risk of groundwater flooding, with the site in Flood Zone 2 and affected by surface water as well. High groundwater matters for leak detection because it produces damp readings that have nothing to do with your pipework. A moisture meter at the bottom of a wall near the river will tell you the wall is wet, not why. Damp at low level here can be groundwater, river influence or a genuine leak, and separating those takes measurement, not a guess. That is exactly the situation where thermal imaging and tracer gas earn their keep, because they respond to the leak itself rather than to general wetness.
The water is very hard. Anglian Water supplies Huntingdon, and the published figures for the PE29 district put the supply in the very hard band. Anglian Water is actually headquartered here in the town, but the hardness is the practical point. Very hard water scales pipework and fittings from the inside, and scale is one of the quiet drivers of pinhole leaks in copper, weeping compression joints and failed shower cartridges. And a leaking heating system that keeps getting topped up takes on a fresh dose of dissolved minerals every time, so finding the leak early protects more than the floor.
A third factor: Portholme Meadow, just outside the town, is described as England’s largest meadow and acts as a natural reservoir in times of flood. The flood water around Huntingdon goes somewhere by design, and property that sits low near the Great Ouse lives with periodically wet ground. On those streets a leak investigation starts by ruling the river and the ground out before blaming the plumbing.
The signs that usually start the phone call
A water bill that’s suddenly jumped. An Anglian Water bill that rises with no change in the household is the most common first sign. If the meter keeps turning with every tap, appliance and valve inside the house shut off, water is escaping somewhere on your side of the boundary.
Boiler pressure that will not hold. Topping up the filling loop every week or two, with nothing visible under any radiator or around the boiler, almost always means heating water is going into a floor or a wall.
A warm patch on a solid floor. A heating leak under screed warms the floor above it. A cold mains leak does the opposite. Either way the thermal camera sees it before you feel it.
Persistent low level damp. A skirting or wall base that never dries, often misdiagnosed as rising damp, and in Huntingdon sometimes actually groundwater, which is why it needs proper investigation.
A hiss in a quiet house. Usually near the incoming main, usually at night.
The kit we use and what each piece is for
Thermal imaging. A calibrated thermal camera maps the temperature of floors and walls. Heating leaks show as a warm plume spreading from the fault. Mains leaks show cold. The camera reads surface temperature rather than seeing through concrete, so we use it to narrow the search, then confirm with another method before anyone talks about opening up.
Acoustic listening and correlation. Water escaping under pressure through a defect creates a sound, and ground microphones can detect it. On longer buried runs a correlator listens at two points on the pipe and calculates where between them the sound is coming from, which turns a whole front garden into a patch the size of a bucket. Acoustic work is strongest on metal pipe. Plastic carries sound poorly, so on modern plastic supply pipes we lean on tracer gas instead.
Tracer gas. The pipe is isolated, drained, and then filled with a hydrogen and nitrogen mix, safe and non-flammable at the concentration we use. The gas finds its way out through even the smallest defect and rises upward, where a sensitive detector picks it up at the surface. Under solid floors, under screed and in saturated ground near the river, this is the method that settles arguments.
Moisture meters and mapping. Used to define the edge of the wet area, to compare damp readings against a dry reference elsewhere in the building, and to confirm after the repair that the structure is actually drying.
Isolation and pressure testing. Before any equipment comes off the van, disciplined valve by valve isolation often proves which circuit is losing water. Not glamorous, but it stops us testing the wrong system.
Where the job gets more interesting around Huntingdon
The historic core: High Street, Princes Street, St Mary’s Street and Ermine Street. Most of the historic buildings here date from the 17th to 19th centuries, in buff and red brick and render, and the conservation area contains 122 listed buildings, four of them Grade I. Pipework in this stock has been altered over two or three centuries, supply pipes can be lead or old iron, and the building fabric is not something you open on a hunch. We work non-invasively here as standard, and where a repair needs access in a listed building, the opening is minimal and agreed first.
Hartford and the riverside streets. Hartford was a separate village until 1935 and sits on the north bank of the Great Ouse. Main Street, Church Lane, The Grove and Old Houghton Road all appear in the Environment Agency’s flood warning area, alongside Waters Meet, Temple Close, Hartford Road, Tennis Court Avenue, Nursery Road and Brookside on the Huntingdon side. On these streets the ground is periodically wet regardless of the plumbing, so a leak diagnosis based on damp alone is worthless. Thermal and tracer gas, cross checked, is how we do it here.
Oxmoor and Sapley. The Oxmoor estate went up in the 1960s for London overspill, with the first houses on Elm Close dating from around 1961, and Sapley reads as part of the same district. This is the town’s biggest concentration of 1960s solid floors with heating pipework buried in or under the slab, often unsleeved. Corrosion where a pipe passes through concrete is a classic failure, and the leak announces itself as falling boiler pressure and a warm stripe across a lounge floor. The thermal signature is usually clear and the repair opening is small.
Alconbury Weald and the newer estates. Thousands of new homes are going up to the north west of the town. New build leaks are a different animal: pushfit joints behind boxing, wastes and traps on plastic systems, and the occasional screed floor with underfloor heating. A leak in a UFH loop can be located thermally with real precision, so one flag sized piece of screed comes up instead of a whole room.
Long private supply runs in the PE28 villages. Older houses in Brampton, Houghton, the Hemingfords and similar villages often have long buried supply pipes from the road, sometimes crossing gardens and drives that have been relaid over the years. A correlator across a long metal run, or tracer gas on plastic, beats exploratory digging every time.
Shower trays, wet rooms, and the leak that is not a leak
A steady share of the calls that come in as plumbing leaks turn out to be sealing failures. Water tracking past a shower tray edge, a failed seal at the waste, or tanking behind the tiles that was never continuous. Testing the pipework won’t find these, because the pipes themselves aren’t at fault. We test the tray, the enclosure and the pipework separately, so you get told which one is failing rather than paying to chase the wrong thing. If the answer is a sealing failure, we say so plainly and quote for the right fix.
Insurance and trace and access
A lot of buildings insurance policies carry trace and access cover, which can meet the cost of finding the leak and making good whatever had to be opened up to reach it, separate from the repair itself. Cover varies enormously between policies, and since we’re not your insurer, we won’t try to tell you what’s included in yours. Have a look for trace and access wording in your schedule and speak to your insurer before committing to anything. What we can do is provide the written report your insurer asks for, with findings, thermal images and the located position of the fault.
If water is escaping right now, shut off the stopcock and call us on 01462 506374. If it is a heating leak, switch the boiler off and stop topping the pressure up, because every top up sends more water into the structure.
What it costs
We price detection as a fixed job agreed in advance, not by an open-ended hourly rate. Price depends on the size of the property, which system is thought to be at fault, and whether the run is internal or buried. Repairs are quoted separately once the fault is located, because a repair price given before anyone knows what is broken is a guess. If the investigation shows the problem is groundwater or a sealing failure rather than a pipe, you get that answer straight.

Frequently Asked Questions
Will you need to dig up my floor to find the leak?
No. The fault is located from above using thermal imaging, acoustic correlation and tracer gas. If a repair then needs access, it is one small opening in a known position, not a trench across the kitchen.
My bill has gone up but I cannot see any water anywhere. How?
Escaping water often never reaches the surface, and around Huntingdon the ground near the Great Ouse is damp enough anyway that a modest leak simply disappears into it. If your meter turns with everything in the house shut off, water is going somewhere.
Could my damp problem just be the river or groundwater rather than a leak?
It genuinely could. Groundwater flood risk is documented in parts of Huntingdon, and low lying streets near the Ouse and in Hartford sit close to the water table. That is exactly why we measure rather than assume, and if the answer is groundwater, we tell you so rather than inventing a leak.
Whose job is the pipe between the road and my house?
Yours. Anglian Water is responsible for the network up to your property boundary. The supply pipe from the boundary into the house is the homeowner’s, including locating and repairing leaks on it.
Will my insurance cover the cost of finding the leak?
That depends entirely on your policy and is your insurer’s decision, not ours. Check for trace and access cover in your policy schedule and speak to your insurer before anything starts. We supply the report insurers ask for.
How long does a detection visit take?
Typically two to four hours. Properties near the river can take longer, because damp readings there need careful cross checking against thermal and tracer gas results before anyone points at a floorboard.
