Water Leak Detection: How We Approach It
A damp patch that never dries, the sound of water moving when every tap is shut, a ceiling stain with no obvious cause: these are the classic giveaways of a hidden leak. The pipe at fault usually sits out of sight, under a floor, inside a wall or below a driveway, quietly losing water the whole time. Ignore it and the damage keeps building long before anything looks seriously wrong.
Everything begins non-destructively, and we only go further if the job demands it. Listening sensors pick out the noise of pressurised water forcing its way through a pipe wall. Thermal cameras show where damp is pulling the temperature of a wall or floor down. Where confirmation is needed, we introduce tracer gas, a safe mix of 5% hydrogen in 95% nitrogen, and follow it with a surface probe. On combi boilers, cold pressure repeatedly sinking below the usual 1–1.5 bar band frequently tells us which loop to suspect before a single board comes up.
Coverage runs the length of Scotland, city tenements and remote cottages alike, and each survey ends with a report your insurer can work from. Same-day attendance is the norm rather than the exception, and the quote costs nothing and commits you to nothing, so you can learn what is going on before spending a penny on repairs.
Common Questions About Water Leak Detection
Can you locate a leak without lifting my floors?
Yes. Acoustic listening, thermal imaging and tracer gas all work from outside the structure, so nothing needs opening up at the start. Each pass shrinks the search area, meaning any later exposure work happens at one small, confirmed point instead of several guessed ones.
Will water leak detection work in my type of property?
We survey houses, flats, tenements and commercial premises all over Scotland. What changes is the mix of methods: pipework and construction dictate the approach, so a Victorian tenement gets treated differently from a new-build bungalow, though both start without anything being opened up.
How much disruption should I expect during the survey?
Very little in most cases. There is no need to move out or empty rooms, we fit around your routine where we can, and any access we do need gets explained before it happens rather than after.
Will your report support my insurance claim?
It is written for exactly that purpose. Trace-and-access cover features in most buildings insurance policies, and price-comparison service Confused.com notes it commonly pays up to around £5,000 towards finding and reaching a leak, with the repair costed separately.
How much is a leak detection survey likely to cost?
Published prices from UK specialist firms generally sit somewhere between £500 and £1,500 depending on the job. Because no two properties are alike, we skip the fixed price list and give you a free quote once we know what the work involves.

How To Tell You Might Have A Hidden Water Leak
Most hidden leaks announce themselves in small ways long before the ceiling comes down. Recognise any of the signs below and it is worth getting the property surveyed, because every week a leak runs adds to the repair bill and the risk to the building itself.
Water Bills Creeping Up
Usage climbing with no change in habits, or a bill that has jumped for no reason you can point to.
Running Water You Can Hear
A faint flow through the pipework when nothing is switched on, often easiest to catch late at night when the house is quiet.
Damp Patches or Staining
Wet marks turning up on walls, floors or ceilings, sometimes with paint lifting or plaster changing colour around them.
Musty Smells or Mould
A stale, damp smell that keeps returning, or mould appearing in rooms that have no business being wet.
Low Water Pressure
Taps and showers running weaker than they used to across the whole property can point to water escaping from the supply pipe.
Lush Or Boggy Garden Patches
A strip of grass greener than the rest, or ground that never dries out, often points to an underground water leak.
Meter Moving With Everything Off
Shut every tap, appliance and toilet off and watch the meter: if the dial still turns, water is leaving the system somewhere.
Peeling Paint or Wallpaper
Bubbling paint, wallpaper losing its grip or plaster going soft are typical results of moisture working through from a leak concealed in the wall or ceiling.
Act on the early signs. Winter freeze-thaw cycles put Scottish pipework under real strain, and stone buildings, tenements and new builds all suffer for it. Catching a leak early is far cheaper than repairing what it leaves behind.

The instruments do the exploring so your building does not have to. MCR Leak Detection engineers combine several detection technologies to place a hidden leak precisely, whether it sits behind a wall, beneath a floor or underground, and the property stays exactly as it was when we arrived.
Thermal Imaging Cameras
Escaping water shifts the temperature of whatever it touches, and our thermal imaging technology turns that difference into a picture. Moisture the eye cannot see shows up clearly on camera, letting us place leaks in walls, floors and ceilings without drilling a single hole.
Acoustic Listening Devices
Pressurised water leaving a pipe makes a sound, and our acoustic listening equipment makes it loud enough to follow. Mains, supply pipes and buried runs all respond well to this technique, and an experienced ear can read those faint noises down to the exact position of a tiny leak.
Tracer Gas Technology
When a leak refuses to show itself, tracer gas leak detection settles the question. A safe, lighter-than-air hydrogen mix goes into the system, finds its way out through the fault, and our sensors follow it back to the source. Complex pipe layouts and underfloor heating respond especially well to this approach.
Moisture Meters and Hygrometers
Calibrated meters and hygrometers measure how much water building materials are actually holding. Those readings confirm whether a hidden leak exists and show how far the damage reaches through walls, floors and structural timbers.
Endoscope and CCTV Cameras
Flexible endoscopes and CCTV drain cameras let us look directly inside pipes, cavities and drainage runs. Seeing the fault confirms the location and usually reveals the cause too, be that corrosion, physical damage or a joint that has failed.
Pressure Testing
Pressure testing puts numbers on the problem: it proves whether the system is losing water and how quickly. Those figures feed straight into repair planning and give insurers the hard evidence they ask for.
Because we carry several technologies to every job, no leak scenario is off the table, whether that is a tenement flat with generations of altered pipework or a new build running underfloor heating. Granite walls, traditional stone and listed-building restrictions are all familiar territory for our engineers.
What Happens During A Water Leak Survey
Every job runs to the same tested sequence, built to get an accurate answer with as little intrusion into your day as possible. Here is how a typical survey unfolds from first call to final report.
Talk Through The Problem
First we listen: what you have noticed, when it started, and anything about the property that might matter. That conversation shapes which detection methods we bring, and you get a fixed price before anything else happens. No extras appear later.
Walk The Property
On arrival the engineer inspects the property visually, noting likely leak points and where access might be needed. Before any equipment comes out, we set out the plan and take whatever questions you have.
Run The Detection Survey
The property then gets scanned methodically, using thermal imaging, acoustic testing, tracer gas or several of these together, whatever the situation calls for. Nothing gets cut, lifted or drilled at this stage.
Mark The Exact Spot
Once the readings converge, we mark precisely where the leak sits. The evidence stays on screen for you to look at, so you understand what has been found and how far the problem extends before anyone talks about repairs.
Put It In Writing
You receive a full written report covering the leak position, the probable cause and what we recommend doing about it. Where a claim is involved, photographs and technical readings are included in a format insurers will accept.
Sort The Repair
If you want the fix handled too, we can carry it out or bring in one of the qualified plumbers we work with regularly. Afterwards the system is retested to prove the leak has genuinely gone.
You are kept informed at every stage, and the property gets treated the way we would treat our own. Full insurance cover protects you throughout, and when we leave, the only thing missing is the leak.

Common Water Leak Issues We Solve
After thirty years there is not much we have not seen. The call-outs below come up again and again across Scottish properties, and each one needs a slightly different detection approach.
Bathroom And Shower Leaks
Shower trays, bath seals and hidden bathroom pipework quietly soaking the room beneath. Thermal imaging finds the moisture with every tile and fitting left in place.
Underground Supply Pipe Leaks
Mains supply pipes failing under driveways, lawns or foundations. Our underground leak detection specialists put the fault on a precise mark so only a small excavation is ever needed.
Central Heating System Leaks
Boiler pressure that keeps falling, or water escaping from radiators, manifolds or heating pipework. Our central heating leak detection service gets to the cause fast.
Underfloor Heating Leaks
A leaking underfloor heating loop is one of the hardest faults to place by eye. Tracer gas locates it exactly, sparing the rest of the floor. Full details on our underfloor heating leak detection page.
Commercial Property Leaks
Water loss in offices, shops, warehouses and other business premises. Our commercial leak detection service works around trading hours to keep downtime short.
Leaks in Walls and Concealed Pipework
Pipes buried in wall chases letting go out of sight, a regular occurrence in tenements and older buildings where pipe routes have been altered over decades.
Freeze-Thaw Damage
Pipework split by freezing weather over a Scottish winter. We find every affected section and record the damage properly for repairs or an insurance claim.
Slab and Foundation Leaks
Water escaping under concrete floors or within the foundations themselves. Our slab leak detection service catches these before the structure pays the price.
If your leak does not fit neatly into any of these boxes, that is fine, we will still find it. And our trace and access service makes sure the repair that follows opens up as little of your property as possible.

Let Us Find That Leak
Water leak surveys across Scotland: quick to arrange, precise, and kind to your property.
The Case For Acting Quickly
No leak ever fixes itself. A slow drip today becomes saturated insulation, mould and structural repairs further down the line, and the bill grows with every week the water keeps moving through the fabric of the building.
Scottish weather makes things worse: hard frosts, sudden thaws and persistent rain all accelerate what a leak can do, and older buildings with traditional construction feel it soonest. The earlier the leak is found, the less the weather gets to work with.
MCR Leak Detection exists to shorten that window. We arrive promptly, survey without damaging anything, and hand you a precise answer you can act on, so the problem gets solved once rather than managed forever.
Deal with it while it is still small. Call the team now and get your water leak found, wherever you are in Scotland.
